"Otherwise you'd have to hook up to the I2C like somewhere in this area" Just got done soldering to a 5700XT to find out the IR35217 I picked is the one that doesn't do Vcore... and the other one is EVEN MORE annoying to get at than the one I've already soldered to.
Hey Buildzoid, just wanted to say thanks for the "Daily stable RAM OC: 2x8GB G.skill Ripjaws V 3200C14 + Gigabyte A520M H + Ryzen 5 3600 " video. Your comment about tCWL below 16 giving you errors was just the nugget of information I needed to get my 2x16 3200 14-14-14 playing nice at 3800 16-16-16. Just passed 140% on memtest (it would crap out by 20% before with tCWL below 16 above 3600 speeds). Come on 800%!
XFX Vcore memory is great BUT AMD WONT ALLOW OVERCLOCKING... this card has unique ways of placing and using capacitors BUT AMD WONT ALLOW OVERCLOCKING... XFX made a really great card BUT AMD WONT ALLOW OVERCLOCKING....
Its almost like people made FX run at 5Ghz 1.5v Complaineda bout temps and power draw. Overclocked vega to 400w and complained about poor efficiency. AMD released a bios update to make vram chips run at thier 14gbps rated frequency, People complained. "fine you want low temps and power draw fine, No overclocking for you" -AMD Normies brought it upon themselves.
It's pretty obvious I think. AMD is ok with OC, as long as lower-end cards can't be OCd to be as fast as higher-end-cards. Then they limit the clocks. If you can OC the 6800XT to be as fast as the 6900XT, why buy the higher end card?
@@titaniummechanism3214 🤔 "If you can OC the 6800XT to be as fast as the 6900XT, why buy the higher end card?" because you can OC the RX6900XT to be even faster 😁
@@shaneeslick Yeah, makes little sense. And yet AMD does limit the clocks. And has done so in the past as well. And that's the only plausible explanation I could come up with.
@@titaniummechanism3214 I've heard that reason in videos & seen it in chat but it makes no sense to me, GPUs are not like a R5 3600 to R5 3600X that have the same Die, higher level GPUs have more 'Processing Units' like R5 to R7, like when some people were saying "Don't buy a RX5700Xt, Because you can buy a RX5700, Flash the BIOS & then give it a Huge OC & get close to the performance of a RX5700XT" yeah, but if you are happy to Flash the BIOS to a risky one for RX5700 then just get an Unlocked Power Limit BIOS & OC the RX5700XT & you get even more performance
@@rikipatel4340 I do support BZ and others. The ads are only worth commenting on when they prevent the viewers’ ability to get into and follow a video. This is a good example of ads causing a negative experience. I found it jarring and hard to follow BZ. Just as he was getting going an ad would start and distract. By bringing up the ads I am supporting BZ’s ability to connect with and retain his community’s attention.
You keep complaining about OC, but as an owner of this card I wanna say I never had to OC for any reason. This card is a beast and stock clocks are more than enough
Well, got this Card yesterday. Its huge and still looks slick. Got a question though (never OCed myself). I logged the cards values while playing with two separate Programs. Both showed clocks up two 2514 MHz while playing and clocks were over 2400 MHz. I did not touch the OC switch, i used it out of the box. How does this happen? Did the UEFI of the MB OC the card? I never cared to much about OCing myself, just bought OCed Customs.
dont hate yourself for ripping off smds, please do more videos playing with old or new gpus, thank you man, happy christmas for you if you care about that but love you man
: Can you explain why there are always parts left out when there is a spot where something could be soldered? Like at 6:04 on the backside there is this row of black bricks :D where five are present and four are missing and C861 is the first one. What would happen if you soldered more of them onto the card? Since you can't overclock it too much I suppose nothing much would happen but would something happen if you could overlock the card more? Would it be more stable or something? I always wonder when I see these open spots because I don't know enough about electronics...
Initially they design pcbs with a lot of extra pads incase they find power delivery filtering problems at testing phase. That's just an example. Sometimes manufacturers even make exposed ground/power planes with solder on top of them to make heat dissipation a little bit better. A lot of extra pads around the voltage controllers could be used for configuration, etc
Is there something wrong with BIOS modding that I don't know about? It worked perfectly fine on my R9 290 & 5700 XT to go beyond any stock OC limits... Are the 6000 series locked down tighter or something?
Buildzoid. Grab your 3-wire SPI kit. (I know you have one.) J4103, pins 4-6. I don't think those are I2C. I think they're SPI to the BIOS, with the phase controllers doing 2-wire on 1-2.
I have an XFX 6900 XT Black and man its a beautiful card but I'm getting some overheating issues. I'm going to put some grizzly thermal paste on the core and see if that helps. I've already configured the fans to hit 100% speed at 80c+, and it helps shave off a few degrees, but it's hitting over 90c (and I'm not talking about their junction temp).
That’s insanely hot for that card, i have been running mine for almost 7 months now and have never gotten close to those temps, did you end up Rma’ing it or did it simply leave the factory without thermal paste and the new application fixed it? (Had a Strix 1080ti that left yeh factory with the thermal paste essentially missing, it was terrifying until I opened it up and saw the easy fix
hey Buildzoid, wouldn’t you mind rambling about caps? Like why capacitors are judged by their origin country (like if japan can’t make bad caps)? Or by manufacturer, as if all nichicons are great by default, and elite is trash . What caps are better suited for specific kinds of work and etc.
the origin thing was an issue in the past because many Taiwanese electrolytic capacitors had issues with failing due to bad solution inside them however, modern polymer capacitors don't suffer for this at all, pretty much all pc parts use polymer capacitors rn, so capacitors don't matter that much, certain polymer capacitor have better performance characteristics(like esl or esr)[like the molded polymer caps] but it mostly doesn't matter as long as u have enough capacitors for it to function.
MLCCs (tiny colored ones) are high speed low energy capacity and less stable under heat and used for signal filtering (VERY cheap). Tantalums/Polyester (Big Black or Yellow orange) are REALLY stable and good for power management in hot areas (EXPENSIVE though). Electrolytic (Big round metal cans) hold a lot of energy so they are used for supplying power/supplying power. They are heat sensitive and can explode when they get hot and as they age they hold less energy. They are still pretty cheap though. Then there are those (brown) "chicklet" gum looking square ones with the rounded corners and they hold REALLY high voltages. They are used in power supplies and in quick discharge situations like a camera flash or in CRT displays. Big (Yellow) Flat Squares with sharp corners are the same just slightly slower discharge than the chicklets. Used in mains voltage like wall adapters. Used for safety/protection. Big-Small round electrolytic non metal cans. These are general purpose through hole capacitors and hold a good amount of power but are not very stable or heat resistant. They are Average in every way possible which is why they are so common. They are mostly throughhole because they are so heavy that they would rip pads off the pcb otherwise. The metal cans are basically the same but surface mount. There are a few other types but they are less common. Hobbyists still use some wax caps because they are used in old radios but they age and go bad after a while and need to be replaced. There are metal foil caps that look like shiny through hole resistors with a red line or a mike and ikes which are extremely precise like 0.25% or 0.1% they are used mostly for precision applications and only hold small amounts of power. This is what allows them to be so accurate because a little more or less metal foil only makes a small difference in capacity. Hope this helps.
hey BZ i did 25° world place for timespy in my configuration yay ryzen 5 1600 af and rx 590, i will tweak more when have time but i did some basic oc, you have any insights about ocing the rx 500 series? (my card is a gigabyte rx 590, seems to be a horrible overclocker), the voltage do something or it is a placebo? the memory timings seems only to crash too... any thoughts? continue the great work love ya
He's done a few vids on Polaris cards so feel free to check those out. For a more up to date video on mem timings, check out his Polaris Pro Duo overclocking video. All polaris cards can be tweaked the same ways. And I believe the Gigabyte 590 was the worst of the bunch. (I have a sapphire RX 590 myself.)
Could the 12v input caps be there to help compensate for crappy PSUs? I mean... I can't imagine a few small caps would help THAT much, but maybe that's the logic?
Could you fool the power sensing by adding some resistors and making it think the voltage is lower than it really is? Or change the crystals to change the switching frequency.
I have a black merc rx6900xt and the vram does not go beyond 2070 mhz without problems, beyond that it is unstable, I get less fps in the benchmarks and the other cards crash and I see that they also reach 2150 mhz, at the circuit level what could be the problem or could it be the Bios the cause? Thank you
From tests (and this PCB breakdown) this looks to be a really good card, just a shame that (like seemingly all of the 6800XT custom cards) it's way overpriced and not available anywhere.
3 months ago it was $799 USD and people were desperately trying to trade this card for Nitro+ variants (size limitations in their cases), myself included. Couldn't get the trade, tested the card, and never looked back. It's amazing
Idk why these companies need to lock down overclocking. How does it benefit them? It seems like its more work to put limits on things than not, and setting records and having good PR from XOCers seems like it would be beneficial. Is there something I'm missing?
Putting 16GB on those cards and capping covercloking for me only means soon there will be next line of cards that will target 4k market. It's like AMD wants to sell same chip twice to people that can afford it.
Its almost like people OC'd FX to 5Ghz 1.5v..and Complained about temps and power. Overclocked vega to 400w and complained about poor efficiency. AMD released a bios update to make vram chips run at thier 14gbps rated frequency, People complained. "Fine you want low temps and power draw fine, No overclocking for you" -AMD Normies brought it upon themselves. Most people think nvidias throttling algorithm is "boosting" just because cards run higher than thier 100mhz base clock.
guys, i upgrade my pc every 10 years. now im used fx 6300, which ryzen 5000 series for next 10 year if i want play all game smooth, some multitask with programming ? and how much ram do i need 16 or 32 GB ?
Shouldnt matter that much which Ryzen 5000 chip you choose. Just pick whatever is in stock and fits your budget, since you can always just drop in a higher skue chip, when you (maybe) run out of threats in future. That is the beauty of AM4 platform. Futureproofing for 10 YEARS into the future is kinda foolish now, judging by how much gains hardware has gotten in just couple of years.
10 years ago folks were using 4 or 8 gb of ram. If you start needing more than 16 over lifespan of system then used ram will probably be pretty affordable. If you need 32 gb today then get it.
If they didn't limit you everyone would boost them to 6900xt performance. Maybe they will unlock them all once Nvidia releases their 3080ti to give them the finger.
A few things: 1. This Merc already achieves 6900 XT performance. I tested it against the 6900 XT and found equal performance, or performance in the MERC's favor. 2. Silicon lottery gold 6900 XTs on LN2 could hit 3GHz. 3. 3080Ti is a ways off since 3090s are higher margin and a 3080Ti would be a cut-down 3090. Dies have been found with certain product numbers crossed out hinting at 3080Tis being changed back to 3090s.
can you please review ASUS ROG STRIX LC RX 6800 XT GAMING OC? the PCB pics are at TPU: www.techpowerup.com/gpu-specs/asus-rog-strix-lc-rx-6800-xt-gaming-oc.b8216
I owned a red devil 6700xt and now a xfx 6800xt merc. Both are good/ amongst the best out there, not a apple to apple comparison(6700xt vs 6800xt) but Red devil run a bit cooler and quieter, xfx however are more attention to detail with thermal pads on the back of the PCB to take advantage of the metal backplate(non on RD 6700xt). XFX merc 6800xt was $200 cheaper in Aus hence me getting it over the RD.
@@darcoz3028 nah, I'm happy to see this comment. I didn't know what allude meant off the top of my head, so I googled it. And it made no sense in the video... I'm happy I know the right word would have been elude.
I think it must be something to do with logic breaking down but even if that was the case, let the users find that out - unless once the logic breaks, the whole card just bricks completely. In which case, it would be understandable why they just dont wanna risk it.
quit doing reviews on GPU when Nvidia and AMD are going to sell direct to Miners Co and leave adv joe wanting it just gives power to scalpers to make 2X -4 X MSRP
