The CORRECT way to gain FREE FPS with any AMD GPU 

Glad you revisited this topic so quick. I’m used to only overclocking nvidia, so it was interesting seeing the amd side.

I like how he just casually uses a 65 inch monitor

I've been an undervolt person for ages. My focus is trying to get my GPU to perform as it did at stock at lower temps. I'm not willing to lose performance, but I want to optimize what it takes to get there.

The quirks of the new gpus and their overclocking potential is certainly going to be interesting to learn about over the next couple months.

I think there is misconception about undervolt. The whole point for me is to run the system cooler with lesser wattage while getting stock or slightly above stock card’s performance. Which has been the case with nvidia gpus so far.

Infinity fabric speed makes a ton of sense, that's a great observation. Maybe when you're pushing the memory too far it gears down to 1:2 or something like that just like the CPUs.

Always appreciate the thoroughness and follow up from your site. If you find a problem that clearly as it shouldn't be, you dig to find out why instead of just saying it's trash and ignoring it afterwards. This helps tremendously as I just switched from a EVGA 3080 to a 7900XT Red Devil, my 1st Radeon card since the early 2000's.

I'd love to see you experiment with water blocks on these. -Removing the fan power draw leaves a bit more power on the table -Eliminating temperature concerns I'm curious as to what your results will be.

For the "perfcap reason" and other sensors, they do show in HWInfo64 along with a bunch of other stats. You can also view graphed data in it. I highly prefer HWInfo64 over GPU-Z.

Thank you! Appreciate all your and the teams work and effort to explain this stuff.

Just had this video on my home page and decided to watch it. Overclocked my RX 7900 XT and got the same score at the Auto OC on the 7900 XTX. Granted, it's been a year since this video came out, and AMD has been doing really well pushing out driver updates to improve performance. I got my 7900 XT july last year for $700, and I couldn't justify spending another $300 to go for the XTX. Seeing how my overclock went, I'm glad I didn't go with the XTX because I'm getting the same performance with my overclock!! Been watching your videos for years, and I'm not the one to comment much. Love the videos. Keep it up man!

Just received my Dad Bod PC Mod shirt when I was watching this video. Ordered 17th Nov..Thx and Merry Christmas from Hull ,UK

Well, on 5000 series, the advanced showed percentage, but the fine tunning options in fact gives you a graph as values, and basically you can redo their voltage/fan curves. And a thing I personally found out, is that you can do the Auto Overclocking/Undervolting, then switch to manual, and it will keep the setting of the auto that you just did, but you can now fine tune it and control the fan curve.

This is actually really helpful for me, built my first gaming PC in about a decade, definitely out of the loop, after all this info I've decided to just use the default OC and leave it at that. Cheers Jay

Thanks for the fast revisit, i was hoping for such a video 🙂

good old school informative jay video... more of these please and thank you for these 2 videos on this subject. I hope you find the cause of it!!

Downclocking of GPU and VRAM is an issue with RDNA series cards, it affects us a lot with yuzu, losing over 40% of performance if you don't manually force a high VRAM clock speed (this is caused by the variance of an emulator workload with a lot of overhead). You can enforce max VRAM clock speeds with video encoding, set instant replay and record desktop to enabled, the encoder will enforce higher VRAM clocks for the video buffer.

Glad you got to see/show the AMD driver recovery. As i mentioned yesterday, i believe AMD's own built in OC tools are targeted are being simple yet functional. 1 button overclocking for the every day user as an option. I will also note that there hasn't been any actual driver releases since before the 7000 series released. Meaning the users are running on press drivers AFAIK.

Honestly, your last video, I was so exhausted and your voice was so relaxing I passed out about a third of the way in. I found the information interesting, but after spending half the day at the Dr's office and being sick, I had nothing left in me. Thank you so much for the wonderful videos though! If I can get one of the new cards from this generation I'll definitely be going back to rewatch every single one of these videos.

For those who are familiar with PBO tuning, you gain more boost clocks when you can keep the temps lower. The “curve optimizer” is a good example of how that works, since you allow higher clock speeds at lower voltages, and get less heat from the lower voltage so you also boost higher. The GPUs work the same, where you just have to keep the internal boosting move the clocks by finding ways to lower temps and/or voltage

Awesome video thank you I just went and bought a 7900xt and was starting to look for videos on overclocking undervolting etc and was thinking there would not be any good reliable ones out for a while. Very useful 🙂

Interesting result. To me it seems like the firmware is lowering (throttling) the workload sent to the memory controllers to keep the power level in check, even though the clocks are high. It's a complex algorithm with many different factors... There's also 24 channels, six memory compute dies so maybe the average or the max die clock is high, but the active die(s) are lowering their clocks and not represented. I'll bring this up with the power team :)

Jay, thnx for this video, I love that you are transparent and are a community centered person, you've shown this often, keep it up!

First thought I have is that the RDNA3 with the chiplet design is a first gen, so there might be some oddities in the beginning like we saw with Ryzen fist gen. Like you pointed out. So for my part, I'd love to see you revisit this issue in a few months when the drivers have matured a bit more and maybe AMD/Radeon could have found the source of the issue and corrected it.

Fast timings is just tighter memory timings, if you are running stock memory speed you'll be fine with fast, unless the silicon lottery really skunked you. If you're overclocking, the default will let you get to a higher frequency. You then have to test if the lower frequency with tighter timings is more performant than higher frequency with loser timings. It's usually one or two percent difference between them, except for some edge cases.

Thanks so much for making another video so quickly. After reading all the comments saying to under volt and is the trick with AMD GPU's, I was curious to know if they where right or not. I'm impressed to see some actual decent OC now with this card your testing, at least in Port Royal, for gaming it still feels silly to me since you only gain a few FPS so it would have to depend on how stable it is for me. I have always found that OC'ing to gain a couple FPS but increase crashes or wondering if a crash in the game your playing is due to your GPU OC or another issue was never worth it for me. But if I buy an AMD GPU I may give this a try anyway and see what happens. This also goes to prove that "higher number" for Mhz doesn't mean higher performance in an actual game as shown when you try running voltage and everything maxed. I wonder how many people will buy this card, OC it so it to a higher frequency but not actually bench mark it properly and play games clueless that they made it worst, haha. So important to actually bench mark your favorite game before/after to verify it actually benefits then just trusting what the OC tool numbers are showing you and running a tool like Port Royal is good for stability testing.

After watching the initial video, i went into my 7900XT settings and fiddled with it for a few hours. After coming from an Nvidia 1070ti having to undervolt felt very wierd, but managed to get the XT to 3.1GHz GPU CLK and 2.6Ghz MEM CLK at 960Mv under timespy looped. So watching this is definitely proof that AMD and NVidia GPUs behave very different to overclocking.

Hey Jay that was me who mentioned not opening the vram tuning section lol. Thanks for revisiting the topic and taking AMD overclocking serious this time. In DCS I get increased performance with the vram set to fast timing.

Hello Jay. I believe it might be a driver reporting issue. If I remember correctly, RX Vega also had an issue where you could overclock it to insanely high frequencies and the driver was reporting those frequencies but in actuality the card was dropping down to it's 2D clocks. I don't know if 3D and 2D clocks are still a thing now with how much frequencies fluctuate but it might be something that is software related and we can only hope that AMD will fix it in the near future.

Jayz good to see you admit to messing up those oc and improve fast. Put power limit to +15% and then undervolt for higher performance. Set memory to fast timings. Test both rt and non rt game, the oc is different if AMD rt muscle is resting. Mine 6700xt did 2,8ghz and 2,9ghz oc on non-rt games. You need to oc memory a lot for small fps gain. Cheers

Finally, someone has done this research. I've been trying to figure out what's going on there for a year now. Thank you!!!

I agree so much about the separate fan control from default GPU clock distinction!!!!

Ancient Gameplays has a complete run through of these settings if you need a few pointers Jay ;)

Cool video, jay. It would be great if AMD could explain in detail these behaviors to us.

That studio turned out great btw, I love it. Great job!

Just wanted to say I'm glad you're finding cool things you want to make videos about in the tech space still!

Im working on a bios editor similar to the ampere bios editor I released. So far iv found there is 3 main power targets and logic. If you dont touch the memory or core clock speed then it will target a total board power limit. You manually push the core clock like what you have been doing then it will prioritize the core as getting the main power budget. And like wise you manually push the memory clocks then it will prioritize the memory as the main power budget. Which is also why you cant enable auto overclock on both of those at the same time.

Thank you for sharing this, I really appreciate it! Gonna try it with my 6800XT Pulse soon and see what score I can hit.

Great advice, Thanks Jay for this video! It surely solved some some mysterious questions...

Hey Jay, any chance you could write up a step by step guide on undervolting cpu and gpu for dummies? Something that explains the process at each step, not just tells you what to do.

Literally just bought an AMD GPU yesterday. Appreciate ya Jay!

I really like this kind of video. Its very informative for newbies and people that have been watching you and overclocking for years even on Nvidia cards. I was able to get another 10fps on my 2070 from information gained here. Thank you Jay and team.

Great video Jay! Appreciate you and the team's hard work!

Based on the deep dive Steve did for the new GPU structure id assume the controller from either the infinity to memory to cpu is the issue and it could also explain the physical power limit too. Look back at the substrate that AMD used between the 6nm memory chips and the 4nm cpu chips in peticular.

Have a look at HWINFO64 sensor panel. That may show more info than the other software. I suspect that the interconnects between the GCD and the MCDs (Infinity Fabric) clocks are having their frequency ratio messed with when you manually push the core/memory clocks up. The core clock runs fast, the memory runs fast and the connections in between are being strangled and cut in half.

I am pretty sure that you're right about the memory speed tanking related to bus-speed dependencies, like with the CPUs. Another cause could be that at certain overclocking values the memory falls into a asynchronous operation, that leads to huge memory latency and/or to many waiting cycles!

I do like How you sit down with the critisism and did another Video about it. Really enjoy these Kind of Videos

Hey Jay, so according to me issue is not the memory, its the core because if mem load is decreasing it means it is not the bottleneck there (if memory clock was decreasing than mem load will increase you can test it by doing the reverse i.e. overclocking the memory for same test, mem load will decrease). So the other part that i can think of is core as it was only reaching max of 2700 mhz (when min core clock was set to 500) i think thats the max it can do stably so forcing it further introduces core streching, try hwinfo for checking if thats the reason ( ig it was effective clock which shows the actual core clock). Waiting for your next video on this 🙃

RDNA overclocking can definitely be a pain, but as a general rule, you want to tune memory first (fast timings when possible). Then you can tune your speed by dropping your voltage. It’s definitely more complicated than that, but what Jay was doing in this video is a lot closer to what you want to do. Ancient Gameplays has a few vids on it, but it you want to try to fine tune it, you increase the uv, then move the min/max sliders to within about 100-200 mhz of each other until you get stability/ fps drops. You’ll hit your lax uv and clocks. Then you usually want to pull back from those maximums for your stable OC. You can drop your min clocks then too if you want.

If the infinity fabric is not the fault of the loss in fps, I believe what might be happening where the fps is dropping (both frequencies remain the same reported: game clock and memory clock, but when the fps drops, the shader clock is getting the short end of the stick. Essentially, the game and memory clocks are both being reported and shown properly, but when manual overclocking is being done, the shader clock is unable to be changed or viewed by the user, resulting in seemingly unchanged clock speeds, but also a drop in fps. This might also explain the lack of memory controller usage.

Jay, a little explanation on the Minimum Frequency at the start of the video. Yes, pulling it up will seemingly force the card to run at higher frequency. But, it becomes a problem when the card runs into a power limit at which it can't sustain the set Minimum Frequency. That's when it will internally downclock/clockstretch anyway, degrading performance. The power management simply doesn't allow enough power draw to keep a high min clock stable. Leave Minimum Frequency relatively low, far enough down that it can still be sustained in a really power-heavy workload. I mean you can already see that at maxed power limit, the card can't really do more than about 2600-2700MHz in Port Royal. Trying to force it to run at a higher minimum clock than that can't work (unless you can disable the power limit). Intermittent load switches in the millisecond range probably even run below 2500MHz. On RDNA and RDNA2, you realistically could only push Min clock up if you gave the card vastly more power limit via MPT.

I bought a RX 6700 XT a few weeks ago. It is a good example that you have to have a case and cooling to go along with it. I put the card in my mid-tower case. I started to run games and the GPU was hitting 80c, but junction temps were toward 110c. I am an engineer, an worked on electronic products for 18 years. A lot of components were rated at 104c for highest temp before problems. So I looked at the case. I added one fan. Put all fans directly to the power supply molex plugs. The mainboard fan connectors were to slow for cooling the case. So I have 3 fans air intake, and two fans air exhaust (including power supply). There are grills in the case the intake air can also escape by pressure differential. I set the Graphics card fan profile to on early at 60c to get ahead of GPU, and Junction temps early. The card fans hit a steady 2600 - 2900 rpm and keep the junction temperature down between 80c - 90c. The GPU runs about 65c, and the CPU 70 - 75 c. I happy with this level, and I don't smell heat, like to hot anywhere in the case. At 1440p this card performs well, about 120 - 200 fps depending on the Battlefield games I am playing.

the 7900XT is my first card after a 1070 and i am rly blown away. sure would have been blown away by a 4090 even more but i come from 1070 budget (which was 450 bucks back then) and didnt want to go quadruple the price.

I agree that there is probably some other clock, e.g. fabric (or whatever they call it on GPUs) that's switching from FCLK=BCLK to FCLK=BCLK/2. It does seems as though something is switching, because it's immediate and significant drops for relatively small changes. My guess would be that the fabric can't match above ~3GHz

I was game stable for a while @ 3125 core 1125mv but it ran warm and I actually gained 1000 points in timespy by reducing the clocks and going to a 1100mv undervolt. It also runs max 75c junction temp so I'm happy with it.

So glad you admitted you messed up last time then just went back and started undervolting and tweeking with software and just got on with it. Well done

The thing is AMDs current hardware relies on voltage and temperature to determine how much performance headroom you have. Lowering the temps/reducing voltage curves tend to leanto higher sustained performance from my experience.

This is why I love J2C so much, he is engaging with the audience. Asking the viewer for help and bringing them into the conversation. Jay you rock!

March 2024: just completed my first build. Used guides by two other creators i wont name; massive issues. Microstuttering. crashes. freezes. Terror. Followed this video. Fixed every issue immediately. Almost doubled my performance. Would love a revisit to this

What a timely video, I just bought a used RX 480 for $50 to refurbish a PC to give for Christmas, and I had to tune the voltage down 90mv to get it a bit cooler and stop throttling itself.

hi jay, it would be cool to see some game benchmarks after u overclock the gpu to see how much performance gain translates from portal royal to actual games

This has been happening for awhile now i remember trying to overclock my 580 a few years ago and wondering why nothing was happening

Definitely interesting seeing how infinity fabric may work, I wonder what drivers can improve. As well as more precise reporting.

Something to do with synchronicity, possibly? The problem seems to occur when moving the minimum clock speed up. Maybe by forcing the clock higher then it's expected to go, in some specific moments different parts of the whole GPU process might get unexpected data one to the other, or there might continuously be instances when a clock tick is wasted for some kind of timing misalignment, or for a forced re-synchronization time out. I mean, with the chiplet design it seems reasonable to think synchronization problems can occur, doesn't it? (BTW obviously I don't know what I'm talking about: it's youtube, yey!) Thanks for your videos!

PREFACE: I have the XT and not the XTX I had the best luck maxing power limit no matter the settings i used after this. I found that i kept gaining in FPS and timespy (dont have port royal) score increasing memory until crash at 2750. 2751 produces instant crash on my card no matter what every other setting is 100% of the time. I left it at 2750 for the rest of this and tried decreasing to see if i would gain performance after the further testing. I then would increase max GCD clock until i would see a drop in performance/timespy score. I would drop 10mV which would let me push the clock harder with performance increase. Once i maxed out what i could push that way i tried dropping the memory clock by 10 and instantly lost performance which did not come back with more GCD clock speed. Overall i ended up at core max: 3150 | voltage 1010mV (minus 90) | memory 2750 | (again on the XT). This pushed timespy from 19936 to 26327 and the 2 main games i tested in CP2077:107>124 and RDR2:141>158 at 1440p Now i hope they fix the drivers to make VR better because that's the entire reason i bought the card. My 6700XT was fine for flatscreen stuffs :( PS: You're def my favorite youtuber mixing PC and gearhead stuff all the time. I feel like you would just be a cool dude to shoot the breeze with about either.

This happens with 6000 series as well. I found it happens mostly when I increase VRAM clock. I thought it was errors occurring within the memory causing the drops.

Well Jay you did it again. I moved the minimum frequency up to just under the max and my fps literally almost tripled

For the reason the GPU drop when you move up min GPU clk , I think it must be related with data feed to GPU : A GPU/CPU to work must have input data to "use" , so if we dont have enough data for a given higher clock speed , it's necessary to give a "fake/artificial" load to the CPU/GPU to balance the load , and this will sink performance .

Bought a xfx merc 6800 xt during black friday, first amd card I ever bought and very happy with it. I like the adrenaline software for overclocking, the ability to set a custom OC profile for different programs is a neat feature eventhough I just settled for a global overclock. My only gripe is that every time I restart my computer it goes back to default and I need to load my profile (might have to do with fart startup, haven't yet tried to disable it) I focused on undervolting for better temps ergo better longetivity, along with an aggressive fan curve (I just don't hear the card fans over the ones in my pc case when gaming). It is also nice to reduce the power draw with the increasing price of electricity. But even for people looking for better performances, undervolting yield better results since lower temps prevent thermal throttling. In my case I went with a stable OC going from 1150 mv to 950 mv (could go as low as 930 in benchmark and most games but would crash in cyberpunk). very happy with the xfx card, I also noticed that the hotspot temp is always very close to the overall temp; the fans and thermal pads seem to be doing a very good job

Reckon interlink between MCD & GCD or between MCD to VRAM is dropping from 1:1 to 1:2, hence Jay's video showing memory controller load halving from 32% to 16%. AMD built some load protection balancing for stability.

Love this stuff, Jay. Interesting to see the progression... I'm very interested in this topic. I had an XFX RX 480 8GB and now have a 6700 XT. On my RX 480, AMD's software had separate voltage controls for the VRAM and GPU. On the 6700XT (and on your 7900 XTX), they don't. On my RX 480, I could up the GPU clock to 1400-1425 no problem. Slightly sigh on the VRAM clocks or VRAM Timings setting? Crash. Now move on to the 6700XT. Similar situation to 7900 XTX but, when overclocking, I've noticed similar but different behavior. On my 6700 XT, I have the max slider set to 2750 and the VRAM to 2100. Here's the difference in behavior I noticed on mine as I was trying to find balance: As I upped the clock, like you, it had very little impact (no negative performance but I'll get to that). If I didn't touch the clocks but upped the VRAM, it did improve slightly. At high enough "Max GPU Clock" in AMD's control center, I would get memory artifacting. GPU OC = VRAM artifacting didn't make sense. If I set it to "fast timings," it would cause a GPU Hang/freezee and force a restart. So, ultimately, what I think I oops'd onto was that memory/GPU thing you're seeing here EXCEPT my VRAM clocks never dipped but I got similar behavior. I either got a freeze or VRAM artifacting. Freezing/artifacting applied to toggling fast timings options, too. Lowering the "voltage" under GPU fixes the artifacting and freezing and allows me to maintain an OC on GPU and memory both with a net gain in performance and reduction in temp (both fairly marginal though). I also have a 4600H/5600M laptop that uses AMD's SmartShift thing where it dynamically changes power availability between CPU and GPU for efficiency. (More CPU = more power to CPU, less to GPU and vice versa. So, I have a few theories but not sure based on the three different generations of cards I've had for AMD but may just be guessing. My suspicion is that power delivery must not be regulated the same on post Polaris chipsets and, on RDNA3, is being shifted dynamically similar to how they've done their mobile CPU/GPU chips in laptops. (Mine's a Dell G15 5505 or something.) RDNA1 and 2 seem to lack the shifting feature so stealing power for GPU ultimately robs the VRAM. That leads me to my other suspicion. On RDNA2, I think the "default" timings must be dynamic and "fast" must be a locked setting. So, on RDNA2, my suspicion is that increasing power draw on the GPU won't lower the actual clocks on the VRAM but it's loosening the timings to lower the power requirement. On RDNA3, what you're seeing looks far more akin to the SmartShift technology on their mobile setups. I'd love to see more tests on this but I think this is something I'd love to hear more from AMD about. I don't think it's a bad thing, I just wish there was more information out there so it made more sense what's happening. Anyway, I could be stupidly off base but I thought I'd share my thoughts since I've had the opportunity to kind of watch the evolution from RX 480 -> 6700 XT and now 7900XTX thanks to you so it kind of paints a picture when you look at those changes and behaviors gen over gen. EDIT: Also to note, my current 6700 XT is the XFX QICK and is set to 500/2750 on the GPU clocks, 2100 on Memory with fast timings on, and +15% power limit, voltage at 1110mV (default 1200). This works stable with no artifacts.

Great videos. I love this type of discussion content. As to what happens, i think that you are right, that something with no visibility is dropping and bottlenecking the performance.

It could be something like the IF ratio on Ryzen. Once you push the core clock past a certain point, it drops out of 1:1

Thank you Jay for all the videos ..

Jay on the undervolting you wanna see something impressive, there's a tool for download that can force the card to 1v or lower, you loose the top 10% of performance, but you save way more in total board power, and the cooling changes are staggering! Ahhh brings back memories of forcing GPU's to 0.975 volts, don't mind giving up a few frames for a seriously cooler operating card

I came back to this video because what Jay says at like 16:50 totally misses me. My GPU drivers crash, then I have to reinstall them nearly every time without fail. I wish I knew what I was doing wrong with my 6700XT. MSI Gaming X 12G Manual OC to 2600MHz@1.05V VRAM tuned to 2100MHz +5%Power. Fan Curves up to max around 50c. Replaced Thermal Paste recently to drop temps, which helped that but not the crashing.

I would appreciate a video about how to properly OC an iGPU like a 4750G Pro, 5600/5700G and so on. It plays along with your RAM of course, but I unless I fiddle with the subtimings, gain in FPS is absolutely marginal. Running a 4750G Pro at 4.4GHz and the Vega 7 at 2.3GHz (1.2v) and my ram 4x8GB @ 3866-CL16 (stock 3600-CL14), I get a 2-3 FPS more. Something comprihensible would be awesome Jay!

Awesome video as always Jay! But yeah what intrigues me. I have been using AMD cards for a while now too and the "Fast Timing" thing is pretty recent. I had RX 5700XT and it did not have it at least at start. I think I saw it first time in 6000-series cards. I really would like to know what is the difference between "default" and "fast-timing"

I think you nailed it with the infinity fabric. It may be multiplier locked to memory and gpu

With the new Amd gpus you actually need to undervolt in order to overclock. There’s videos (2 I’ve seen so far) that perfectly show this. The way I understood it is that, at least with the 7800 xt, the amount of power the card draws is locked. So by undervolting you’re giving more headroom for higher clock speeds within that envelope of power. Gonna test this when I build my pc with hellhound 7800 xt

My 6800xt never changes the voltage from 1150mv if I try to overclock the frequency regardless of whatever voltage I set so its nice to see that the you actually have control over voltage with the 7000 series. The only way to get the voltage down for me would be to down clock it or use MPT. Always love the content Jay, especially the water cooling videos cheers!

drivers are another important thing with AMD GPUs. i havent updated the divers on my 6600XT in almost a year now. i got the latest drivers yesterday and i saw up to 50fps gains in some games.

Thanks for making this video. I have the 6650 XT and I tried a few changes and the AMD Stress Test (top right corner of software) kept crashing whenever I ran its built in test. Thinking it was me changing dials that caused it, I clicked on the Default tab. I ran the test - THE SOFTWARE STILL CRASHES!!! This is the first card I've had so much trouble with! I mean I have an AMD Ryzen 7, 32GB DDR6 RAM and this card. And it's been hell trying to do settings for games. I'm almost at the point of just refunding it and jumping to nVidia but I don't want too because I've been about AMD for years. But, trying to play Microsoft Flight Simulator with no stuttering of any kind at any point is a pipe dream so far!

thank you! i have a 19400kf and a 7900xtx and temps were shocking from stock and default settings in bios, since i watched a couple of videos on this from you i know get 5800hz on p cores when underload no higher than 85c and with this setting on my phantom gaming 7900xtx i gain 600 on my benchmark and i can finally have fans on a custom rather than full speed with all my case panels on (i have 9 fans in total) and it still got stupidly hot, so again i thank you!

My experience with overclocking my 6700xt is that I was able to just max the vram at 2150, max the powerlimit and set the max core speed to 2800. This is mostly stable and I have tried lowering the voltage but that gave me less performance and less stability

Youre an incredibly valuable source of information, thank you Jay!

Gotta say that opener was perfect I love it

good stuff jay! happy holidays

I love you content I just built my FIRST pc your videos helped me out alot!

It is great that you decided to make a video about this on amd gpus. I been knowing about this for a little while now and been trying to tell people about it but not very many people believed. This person does know what he is doing for sure with this. It is great that you figured this out to tell everyone.

If the card is leeching the VRAM voltage to stabilize the GPU, it is possible that the VRAM effective clock is slown down due to memory error detection. The reference model tunes its VRAM clocks while the Red Devil maintains the VRAM clock and working out the errors. The GPU may be working out the lowered VRAM wattage by selectively suspending memory modules to keep the data refreshed but not fully powered until used.

I've had good luck overclocking amd cards by also changing the MIN frequency to 100-200mhz lower than the max frequency for manual OC. It seems to help maintain a higher average mhz during a 3d mark run.

I just hope AMD is working some more on drivers and features until 7000 series drops to realistic prices. I would totally go 7900XT or XTX this gen if one drops to 700 to 800 euro. A slider for performance % like Afterburner has would also be neat. I also hope Intel Arc catches up one day so we have 3 major players. Just put more resources into driver, software and feature optimization. 👍

To properly overclock, start by sliding the power slider to its max setting. Next, set the max frequency to 3200, go to vram next. Enable fast timings, set vram clock to 2700. Then undervolt to 1050. DO NOT TOUCH minimum frequency. Now you can go back through and tinker with each setting until you find stability in all games you play.

I sometimes underclock to increase longevity, but also for less heat and quieter performance. For people with acheap system, burning through their circuits by overclocking, I usually suggest that they switch auto tuning and such off, which then also reduces fan noise. (yes at a cost of some performance, but they usually don't care for games in such a case.)

As far as the fan control being locked in anything besides custom tuning, you can just enable Auto OC, Rage mode, or whichever preset you want... And mimick those settings in a custom tune. You can save different tuning profiles. This is what makes Radeon software so much better than GeForce experience.

Can't wait to see Jay hook up the AC to 7900 XTX! Curious to see how it reacts to being Colder!

New to OC but after watching this I was able to increase my heaven score by 6% on my 6700xt, Thanks Jay!

This video helped me a ton, I have an xfx xtx and was wondering why I was not getting the performance as some bench marks out there. The first mistake I made was using 2 psu cables and daisy chaining one of them like a moron, I added the 3rd cable and automatically gained 1000 points in time spy. I then followed the video and set all the OC and undervolt what they would have been if you clicked on one at a time altogether and maxed the power and gained another 2k points. Went from 170fps in warzone 2 to 210fps.

manual fan speeds used to be a thing but they decided to take it away, I had my fans tuned when I wanted random temp spikes to go away while mining
