Kicking Ryzen 7000 into HYPERDRIVE! Overclocking, Curve Optimizer, 5.85 GHz! 

Thanks! This is great advice comming so early in the life cycle of all this new hardware. Early buyers are really on their own so much more. Your kind of help is really needed. Please keep this focus into the near future. Thank You.

Wendell, thank you for going through all of this and doing it in such a way that people who aren't nearly as tech savvy as you or the majority of early adopters of AM5 may be. Coming from a 5800x and running it all stock to as of later today a 7900x learning how to actually use curve optimizer is a benefit for damned sure. I would be interested in seeing you go through similar steps using some of the different bios that are out there (Asus, MSI etc) I would also be interested in seeing what if any extra headroom you get or how the temps may be improved going from a 360mm rad to a 420mm rad. I wouldn't expect a massive difference but then again, AM5 has already shown with a few slight tweaks the performance and thermals are pretty damn good.

Glad atleast your channel wasn't ignorant and decided to a look at curve optimizer. Its shame because its basically two settings for AMD to drop 30c, be 4% faster than stock and atleast 40% more efficient Than stock. Why its not by default...

Thank you very much. I have the 7950x on an Asrock board so it's like you were speaking to me directly, lol. I am able to get the PBO stable at -30 and get an all core boost between 5300-5400 MHz during Handbrake rendering. 95C temps on a robust custom loop at 175 watts. I was curious if I was getting my full potential, as I am newer to AMD OCing. This video was a great relief and I appreciate you spelling it out for someone like me.

Here in Denmark the Liquid Freezer II is actually around 100DKK cheaper than the pure loop. So which is the cheaper one is highly dependant on where you are.

One of the cool things about Ryzen Master is that it will tell you which 2 cores are the best performing / boost highest at the stock voltages. So if you want to go into the weeds of optimizing the curve for each core, having a more aggressive offset on your top couple of cores is a great place to start and may help get that last bit of single core performance. Another helpful thing when using the curve optimizer for each core, when you run into stability issues there's a way in the windows event viewer to see which core caused the system to crash (I forgot how to do it off the top of my head). This is incredibly helpful for pointing you to the next adjustments.

Awesome video and nice results. Everyone is talking about higher power consumption, so it's cool to see that it's mostly just allowed to consume more, not required.

Nailed it on the Curved Optimiser. Love your work Wendell! Could you do a board review with a itx board? I'm looking to do a new system build, and want to try a SFF PC. A review on the Gene would be amazing. Keep up the great work dude! 👍🏻

I'm definitely interested in seeing more on curve optimizer. I'm one of those who do gaming, but I'm also a hobbyist when it comes to making mods. I will look into upgrading from my current 2700X when the prices of the new platform drop. In particular, I'd be interested in hearing your thoughts possible merits for separate curve optimizer profiles for gaming and productivity.

Takes an engineer to explain the engineering-specific stuff. RU-vid hypebeasts that built their own computers since -insert-age-here- are not a good source of pro and cons for a new product. This is the first video after which I am actually interested in this new architecture

At a setting of negative 30 on Curve Optimizer, my 7950x hits 5750mhz on three cores, and 5500 on all cores during most benchmark runs. Then I limited my temps down to 90c. This dropped my cores down to 5350=5400. So I'm happy with that, and my system runs very quickly on all tasks and sims. With this setting, I scored over 1500 on multi in CPUZ and 750 on the single thread. I also got a score of 38240 in R23. Love this processor. I'm using a Strix X670E-E wifi, 64gb of GSkill Neo 6K and a 7900XTX. I NORMALLY in the past always bought the Hero board, but this go around it was WAY overpriced, and the Strix actually was better equipmented for a lot less money.

The Arctic AIO's are monsters for the price. On Arctics eBay store I picked up a 420mm for $65 earlier in the year and it handles my i9 7960x at 4.5ghz like a champ (over 300w under load). The 240's and 280's are regularly under $50, all include full 6y warranty too.

Hey Wendel, any chance you'll be doing some testing/comparison with 2 DIMM vs 4 DIMM? I've heard the situation isn't great in respect of ram clock speed penalties but it would be good to know what is possible and what to expect, specifically I'm looking towards 64GB (2x32GB), but would like to know any upgrade routes should I need more ram to expand that to 128GB (4x32GB), nobody seems to be testing that at the moment because they're probably busy with AM5 stuff and Intels new stuff for reviews.

Nice video, looking forward to the next one! More in depth overclocking would be great. Also what's your fan curve for the AIO?

This has been the most helpful video for this launch! I delayed watching it because "eh, I've already watched thefarmer delidding it" but I should not have doubted you.

I can't wait for people using curve optimizer, tweaking it for 1-3 days and then complaining about "shitty game XYZ crashing because devs are stupid" on reddit declaring that the issue is not their "stable system". PS: My 5900X runs about 150Mhz higher (all core in Blender) using curve optimizer and uses less power. Since the new main boost target is temperature, you should be able to get a lot out of these CPUs if you do it on a "per core basis" but proper tweaking can take weeks of work. PS: If you want better maxed out all core performance, leave the "Max CPU Boost Override" Setting to 0 This setting will greatly influence your possible curve optimizer settings towards the positive range, which you don't want in that case.

I've seen the ECO mode settings that AMD is still working on right now and I like this better than anything else. But, what I WISH AMD would do is allow more settings, and this would accomplish the reduction in clock speeds along with the reduction in power all in one easy step. For instance having the settings of 150W, 120W, 105W, 80W and 65W for the 170W TDP parts would be GREAT. That gives you pretty much everything you need right there. For the 105W TDP parts, 95W, 80W and 65W ECO setting would be GREAT. Frankly I'd just set it at 90W which would have little effect on the 7700X in light loads.

I used this video guidance today to set a -10 setting in curve optimizer or whatever that setting is, I already forgot. haha. Thanks Wendell.

Wendell i really appreciate what you are doing, your explanation make it sound really easy, if it's not so much trouble can you make one of these video yearly because in a year or two some bios update will be available and maybe some better hardware will be available for amd 7000s series. That would be really great. Thank you.

thank you Wendell

Thank you so much. Totally awesome!

Wow didn't even know I could do that using the curve optimiser, my processor runs so much cooler now and my fan doesn't even ramp up when playing a game. Honestly though this curve optimiser should of been a stock setting or optimised by defaults when you load it, becasue it doesn't seem risky but it's a massive enhancement.

Well done! Alot of good information. Thx

Awesome Video please keep these AM5 overclocking / undervolting videos coming Great content !

Built a 7950x myself with your excellent help.

Wendell, did you try the 4 dimms? Apparently Steve at HW Unboxed found that 4 dimms worked fine on all his systems, and actually increased fps by a couple %. Could you actually test this to see if its true for you too?

Hi Wendel, did you try a heatsink and fan and monitor the difference between the CPU temp and the cooler temp? No matter the heat produced in the processor my cooler is staying close to ambient running small fft, etc. with one exception. I have a Passmark score of 38395 so I'm seeing a substantial bump over stock. I am using an AsRock $169 B650 board. I have the memory set to aggressive Expo 6000 CL30 and a -30 PBO on 7700x. The cooler is an Artic Freezer 33 TR single fan. The only thing that lead to a power shut down is when I increased the voltage to 1.275 and turned off PBO when that happened the cooler still stayed ambient including the back of the cold plate. With stock or with PBO the slow heat exchange through the IHS isn't causing problems and you can run a silent fan speeds. Pushing the voltage and the IHS is acting as an insulator. Steve at Hardware unboxed used a Wraith cooler which is all a non-heat pipe solution and saw degradation in performance. I'm not seeing that.

If the cpu can technically go up to 115c, you can literally mod zen 4 computers into zojirushi style water boilers. Plays your games AND cooks your meals? Truly a new age we're entering.

Thanks for the information good sir.

Looking forward to the follow-up video!!!!

Subbed, love the content 👊

@Level1Techs 11:52 Did you mean 5950X or did you mean to say 7950X?

This video and debaur video helpped me tune my 7950x

This guy's conversation is pleasant

Excellent video!

very nice, thanks. i still have no idea which of the new cpus is the best bang for the buck :-) i guess the 7700x, but i'll wait a bit for prices to settle

good advice ....subbed

Thank you for the heads up about CPU-Z and using avx mode

Hey Wendell, what was the Linux GUI tool you used for overclocking?

I’m looking forward to playing with AM5, but as I have 5950x and 5900x PCs, I think it would make sense to wait for the X3D versions and for the hardware to mature a bit.

For my 7950X I'm using an EK AIO Basic 360 with fans swapped to Noctua NF-A12X25s, and with my PBO + curve optimizer tuning I'm getting single core boosts of 5.93 GHz! I'm very impressed with the performance, though it still runs very hot under full load

got a new 7800x3d, did a -15 offset, and ran a few games with it trying to monitor temps (things are a bit spiky, and i've had some instability with like FAH for an hour will stablise at 77c, and then occasionally i'll get spikes to near 90 with an NH-D15 with low load) ; ive seen hwmonitor reporting >6ghz on most cores max, but how much you trust hwmonitor is up to you, so it's definitely doing something in those cases. it also reports only 20% util while folding with ~4.6Ghz boost, so grains of salt everywhere.

It is a pity that ASRock doesn't have an eco-preset: undervolted and slightly underclocked for all-core while maintaining the highest single-threaded performance. I am confident that most users would get the best user-experience that way. Zen4 seems to come quite overclocked out of the box, too much past the sweet spot. Like losing 30% performance for 25% of the power without even undervolting.

Regarding your comment on tower cooler. My ice giant prosiphon with no fans mounted on the cooler has no issues cooling my system. 5.4ghz all core in R23 all day np. I do have a 200mm fan on the side panel about two inches off the cooler, but this is how I cool it with a near silent system. Thermaltake V21 with only four 200mm noctuas on it.

Im completely new to all these features PBO and Curve Optimizer. Do you Curve Optimize first, and then add PBO negative offset afterwards? Further more, I see alot of people disable PBO Limit in BIOS, however my ASUS X670-E Pro Art doesnt have that feature, or i cant find it the very least. Is it something that is necessary? Further more, i cant change PBO to Advanced, but have set it to Enhancement.

I'm looking forward to custom loop results trickling out. Decent pumps, proper thickness rad(s) and greater thermal mass ought to make quite the difference, for both performance and noise. The way [top end] CPU and GPU power draw's gone (and headed?), custom loops may well be become more than a mere vanity project. Probably also gonna see thicker AIOs rolling out soon, which'll mean cases are gonna have to make room as soo many are designed around the current skinny ones, which'll be a boon for silence freaks running the mid-tier components.

Just a PSA I'm currently rocking 4 DIMMs at 6000 no problem on a 7950x

Hello Level 1 tech. What would you a year later now for my 7900x if i wanted to go water cooling AIO? Still pure loop or something new? Thanks.

I only got another 140mhz out of my 7700x. But the power draw is down to 90 watts and the temperature came down to 70C. I'm really happy with that.

super handy thanks Wends I have the aorus master and the 7900x not had a chance to tinker yet I'm gonna get to it with this valuable info also by the way huge open loop cooling dual rad one of which is 90mm thick lol if the silicon gods have smiled upon me this could be fun

Nice nice. I don't even know what this is, but sounds like it's an easy way for beginner OC gamers to OC.

I've noticed those looking at CO are using All core offsets for AM5 when it always seemed best to test per core on AM4? Is all core just work better on AM5 or is there reason to explore a per core offset still?

Maybe try ECO mode on a linux compile session, if you can do that. Maybe not overheating the processor will actually lead to faster compile times ! =D Less throttling hehe. Seems to work for (gaming) average FPS ! ;) Less low minimums more steady FPS.

The Arctic 360, right now on Amazon in the US is only $15 more expensive than the PureLoop 360.

FFXIV Endwalker BENCHMARK!? I ran the same settings with a i7 12700k (stock), RAM at 3200 MHz XMP (stock), and RTX 2070 Super (stock) and got 21249. You were able to get about 13k more points. That system is about 38% faster than mine on that benchmark.

im using an AM4 cooler i modded to work on the AM5. (direct die LM). do you think the physical mass of a waterblock would have changed - in that the AM4 block might have less mass and thus less cooling power? its a phantechs c360a

Please do per ccd or even per core curve optimizer testing.

Got super lucky, stable at negative 30, temps dropped from 75 to 58 in game!

CPU Cooler Roundup you say? The one I'd like to most see on there is the Arctic Liquid Freezer II *420mm*

Furthermore, 95c is the temperature target for 7000 series. It's designed that way.

Is the Razer Hanbo auto compatible with am5? I just bought a asrock x670E Taichi. Will I be able to install my razer cooler with it?

Some notes: 1. These chips/zen 4 was designed for laptops. 2. Lowering power settings can lead to higher average FPS, because of higher minimum FPS, probably caused by less throttling because no more overheating, ain't that funny.

My deepcool castle V2 360 cools it pretty well. Had to buy a new bracket for it.

ughh :( I need to run 4 dims (128gig) for rendering and sim purposes.. Has this improved at all?

Last week upgraded ny 5600x/asus b450/32GB 3200 to 7700/B650M PG Riptide/KingBank 6400 CL32, and with tweaks I have quite happy with the final results: BIOS Settings: Memory = 6400 @CL30/38/38/80 1.4V FCLK = 2133 MCLK=UCLK/2 PBO: Advanced/Motherboard, Scaller 10X, Positive 200 CO: All core, Negative, -30 iGPU = Disabled BIOS Thermal Limit = 89C Cinebench R23 Multi/Single = ~19,200/~2000 (~44-46W/~114-116W) Idle = ~49-51C (Windows 11; room temp ~23C) Games max 92C Load (Cinebench R23) All core=5.1-5.2hz @89.4C Single Core = 5.49Ghz (59-60C)

I can get 5.5ghz all core on my 7600 (non x). Set PBO to +200 Curve optimizer -42 (-45 max but lowers benchmark score) This brings me to 5.35ghz so I had to raise the FLK/Base clock from 1 to 1.3 which brought it up to 5.5ghz all core at roughly 72c-75c on my Arctic freezer II 240. Raising FLK also seems to have raised my from from aggressive 6000mhz cl30 to 6180mhz? at CL30 still.

Just got my 7950X based system and I’m getting 5.65 sustained speed without using anything other than Adrenaline. Cool. I don’t think it would be wise to overclock ‘more’ (obviously somehow it’s already overclcoked) for a .15 imperceptible speed ‘boost’.

Would be supercool to see if you can build a whisper quiet fast machine with these cpus, limit it to 65w perhaps 4.8 ish all core or something like that so the fans can stay under 600ish rpm with perhaps a 420mm aio.

Hey Wendel, how are you? Q: Do Intel or AMD consumer class (not workstation or server) current or upcoming motherboards have enough PCI lanes and bandwidth to handle a video card streaming 1080p uncompressed(or very minimal compressing) data to another card, say an Intel ARC, so that second card can do real-time hardware AV1 encoding and stream to RU-vid?

@wendell Can you do a video using B650E; maybe the Riptide?

Regarding the "a lot of electrical load" for having 4 DDR5 DIMMs and trying to run them at, say, 6000 MT/s. I am EXTREMELY curious right now... does Intel have this problem ? Can you run Intel i9 12900K on a higher-end motherboard with 4 DDR 5 DIMMs at 6400 MT/s ? Because I haven't heard of this problem before, only now with AM5

What difference between leaving PBO Limit to motherboard vs setting the limits listed by overclock3D of 140000, 110000, and 172000? I’m using ASRock B650E PG ITX with a 7950X

Hello , umm i was wondering what is the max frequency you can run with just 2 cores loaded without HT under prime 95 ?

I just limited my 7700x to 75c thermal throttle limit and I consistently score over 1000 points higher in cinebench r23

What program is Wendell using at 0:40?

What is the difference of setting the bios for OC and curve optimizing vs using the ryzen master utility?

Based on what I've seen in this video and a couple others, (Optimum Tech comes to mind), it seems quite odd that AMD made the defaults so wasteful when with some judicious tuning you can get more performance with lower temps and lower power draw. I suppose the left themselves a lot of leeway to adapt to whatever Intel does with their next release, but the power draw numbers at release were a big turn off for a lot of people. I really want to see someone do a test to show just how bad it could/will get if you try to reuse an AM4 cooler, particularly air coolers with these new chips at stock settings as well as tuned for more sane power draw.

I'd love to see Ryzen 7000 with ZFS and DDR5.

I was able to just drop my 7700X straight into the -30 maximum my motherboard allows and it just werks. Three months after I've built it and it hasn't shown even a hint of a symptom of instability. Not sure if I just won the silicon lottery hard, but at that level of undervolt it barely hits 80c on stress tests now.

I got 4 dimm expo 6000/30 timing ram to boot, but it I got BSOD every few hours. So far it's been stable at 5800 though. x670e proart creator+7950x

Thanks for this video, just pulled the trigger on a 7950! What specific cooler do you have? Will a "EK 360mm Vardar High-Performance AIO" be sufficient?

Curve Optimizer at -25 on a 7800X3D, 32GB 6000CL30. Apparently should run at -30 even, but I'll settle for that. Just started dabbling with OC. Not looking for numbers, just something decent, stable, and lower temps & power, with a NH-U14S, can't go crazy anyway.

Why Windows 2009 instead of 21h2? You're missing out on the new scheduler changes!

Derbauer got a 20c drop delidding am5, insane result for sure like 400+mhz

Just in case an ASRock representative is reading along, please put websites in the menu of the BIOS. Not everybody has got a smartphone, I actually don't.

Any chance of you doing a video for X3D CPU ?

This tweaking definitely makes 7000 series a bit more attractive.

Can you look into an issue with dual ccd am5 chips failing avx2 when running single core multithreaded workload at completely stock settings. No pbo no CO or expo. I have had 3 chips fail avx2 fixed occt cpu stability benchmark now. Only way to get them slightly stable or delay the errors being thrown is to give the non vcache cores positive co.

Question is. I can use -30 on my 7900x and it's stable. 92c so far under cinebench. question is can i keep that negitive curve and some how ask for little more cpu ghz? I don't know how to ask. I am doing 5.4ghz at above settings but can i ask for like 50 more mhz higher clock? Or should I not worriy?

I did put it at negative 30. is that bad? Did boot och i have 24c thermal.

Hey man I've just built my am5 system it's an Asus x670e-e Ryzen 7700x d.skill 6000 cl36 kit. But nothing i do lets me use the expo profile. If i set in bios problems booting. If i set in Ryzen master it works then randomly i get recovery screen on boot any idea what it might be? Have you experienced anything similar?

Core cycler makes curve optimizer way easier to stability test quickly

You are calling negative 18 CO aggressive? I got negative 32 stable! R23, R20 and Prime 95 tested. R23 best result was 40271.

My 7950x runs all day @ 6050 with ddr5 6200 with a older water loop with co @-25

Considering a few of these for rendering, do you think it's possible to get 7950x stable

I can run a stable -19 curve on my r7 5700g, but how i know that single cores are stable at -19? It is gonna push more ghz and maybe its not stable overall

Euh, says right there at 0:28 maximum clock is 5.7 GHz not 4.7 Ghz like you seem to think, hehe.

I got a launch 5950x one of the cores can only do a -4 offset in optimizer yet some can do -28 lol

Arctic use AM4 backplate on LFII but one of the manufacturers had a slightly different z height of the backplate which negatively impacted cooling, 1 or 2 degrees at idle but double digits when go brrrrr. (either msi or asus, I use both boards and bring the known "good" backplate with the arctic).

Why are you so sure that '99 % of scenarios you'd be able to set negative 10''??:D Cause that was not was the case with 5900x, i have one 5900x that 3 cores accept negative13 ,but 2 core need positive 0 or 1 ! I know that first the best CCX always accept negative 10-15, but the second CCX can be shitty and one or two core of second CCX may need default or positive 1, i read a lots of stories on reedit and on AMD sites about this probelm, and was not 1 page was 50 pages writes there, i know cause i was have same problem about 2 month i read about it last year, and i could't return the cpu cause at default it was working good:D I see this week 2 other guys who confirm same things about them 5900x in the Optimus review of 7950x curve optimizer, olso Optimus was saying that even is bad siclicone all cpu will accept negative 15 on all cores he say '' you just set negative 15 on all cores and forget'', that's another bullshit cause now we are 3 peoples with 5900x that noticed him that was not the case with 5900x. Also when you manage negative 15 on all cores, and even it's stable at max freq with CPUZ, OCCT, Aida it was still rebooting at idle, no one saying nothing about that lol, first it's can reboot even after few days, then i get one after weeks, then the last one after 2 month that's was the last reboot at idle. But it took about 2 month to adjust the curve to not rebooting at idle. So yeah it's more like lottery silicon not 99% or 100% like peoples saying on them reviews. Still i can't complain about my 5900x cause is booting about one year at 4875 -4900 Mhz with my shitty courve 0, -13,-13,-13,0, -1,-2,-3,-4,-5,-5,-1, and with max cpu boost clock overdrive + 0(+50 Mhz = blue screen lol) and the temp is good with 240 aio freezer, but i still complain when i see ''you set negative 10-15 and forget ''. On the other hand i have also the 5600x that can boost at 4850 Mhz with +150 Mhz and with negative -8 and all 6 cores guees this was better silicon, so yea still lottery, one good another bad:D
