For reference: the standard setting (2224 MHz target, 1025 mV) with PT +15 is like 200+ W with ~50 FPS. So one can achieve more performance (54 FPS, 2400 MHz target) and 170 W power draw (with 900 mV). Insane!
My RX 6800 is able to do GPU 2400Mhz, VRAM 2100Mhz at 885 mv and a temperature of 60C at 210w. I have an ASUS TUF gaming card and they use the same cooler on the 6800 as the XT and 6900. The result is ridiculously good cooling. Other manufacturers use the 6750 cooler on the 6800 and theirs run hot. I use OCCT software for stability tests because its free and it will give you actual windows and software errors to troubleshoot. My system can run with no errors at its current state. Also, I use the standard VRAM timings because I gain almost 8c and 30w with it enabled for negligible performance gains. The RX 6800 is insanely underrated.
Not to say that the RX 6800 isn't underrated, but that also sounds like you got a great sample. I'm currently at 925mv targeting stock clocks (2274mhz). 900mv kinda works for me, but it's not stable in all tests. I haven't tried increasing core or vram clock targets at all at 925mv yet.
@@labombaromba I have Smart Access memory enabled and fast ram timings turned off. Otherwise I wont be able to maintain my current settings. When I perform testing, I verify my CPU and RAM combination works before touching my GPU. Often times I am able to push my GPU further because the rest of my system is finely tuned.
what fan speeds r u running to get 60C@210W ? I also have ASUS TUF 6800 and its pretty mediocre. Now i'm on 930 mV / 2200 MHz and +10% Power Limit. GPU/HOTSPOT is 63C/71C. TGP is 147W with 1325 Rpm - this is heavy gaming load - FInals Multiplayer which, I found, was game that quickly crashed GPU Driver in case unstable(while Un-engine & Metro benchmarks gave nothing) Is there a way to fix GPU MAX Frequency via MorePowerTool? Any lower voltage - just get stopping driver errors...
@@yingbxua6240 My case is a Lian Li Lancool II with Lian Li SL 120mm on the rear exhaust, two 140mm on top, and modified case for three 140mm on the front. I had never really had a problem, however I noticed better tuning performance after updating my computer with a fresh windows install. My card is currently at 890 mV, 2400 MHz core frequency, 2050 MHz memory frequency with fast timing. If I use regular timing, I can push 2100 MHz memory and 2500 MHz core frequency. I enabled power tuning but leave it at 0%. If I move the power limit slider at all, my GPU will crash. I used MorePowerTool, but found it causes more problems than fixes. The only other tool I use now is OCCT for diagnostics while tuning with Adrenaline.
I'm sure I can do better but I just did 950 / 2200 with power limit maxed out at +10% and am pulling 150-160w instead of 215w. In the cyberpunk benchmark i only lose 5% performance
@@M4Looney thanks but I dunno how to change the frequency since it has alot of options and numbers on the frequency tab. Still having black screen after 30mins of playing graphic heavy games. I'm getting frustrated already.tzk
Hi, first: which card do you have? second: frequency can only be changed in Wattman or tools like MSI Afterburner. But you could try applying higher or lower power limit and lower voltage (higher voltages can only be applied via hardware mods). From my experience you will get higher performance with lower voltage, but not every card can manage high frequency at low voltage. Greetings, Looney's Tech Channel
@@M4Looney ahh ok so the frequencies on MSI after burner. I got a 2nd hand Gigabyte 6800xt gaming OC 16GB Full specs: MOBO: Asus Prime z690-p CPU: i5-12600KF GPU: Gigabyte 6800xt GAMING OC 16GB RAM: G.skills ripjaws 5600 cl36 DDR5 SSD: Adata Legend 850 lite 1TB PSU: FSP Hydro G Pro 750w HDD: samsung 1tb ssd Monitor: Nvision 27" QHD 180hz The thing is I wanna run this on 180 refresh rate. I dunno if I should reduce this but that beats why I bought a 180hz monitor. =( I need to undervolt my rig since I'm getting hotspots @ 103-107⁰C done on 1050mv but I can only play like 30mins. Which driver is latest that is stable?
Yo Bro, i have mine totally stable on 2480 2150 fast timings at 900mv. Im on 22.11.2, the latest driver are good? I had some trouble with 23.2.1 cuz cant keep the same oc. Maybe i must try to do 950mv? I Will test it (6800 xfx qick)
Hi, nice to hear from you! Yeah, mine does 2500 MHz as well but on 950 mV. I could go higher on the max freq. or lower the voltage. I'm on 23.2.2 and so far so good. I even gained a few % on raytracing performance. Two things that are meh: - I have a CPU-OC in Wattman (R5 5600 +200 MHz) but it is not showing under performance - After a few hours with the new driver lot of the performance metrics are not showing in the driver -> reduced parameters to show in the overlay. Besides that (and the bad scaling when recording, issue can be present in the former drivers I guess) driver is good. More performance; MPT is also working just fine. Greetings
@@M4Looney i Will try the new driver than...for the cpu OC i prefer to do everything on BIOS with pbo + new curve fan settings. Im on 5700x so our builds are similar. Your vid are Always intersting, keep up the good work 💪🏻
Yeah, try a little higher voltage like 925 / 950 mV. I've already heard some folks that this is driver dependant, too. You got a very nice GPU, too. Not many can reach those numbers I suppose. A very important thing that comes to my mind: Even though I can run the card @ 2150 MHz FT performance would actually decrease a little when I'm doing so. Check with Timespy or timespy extreme as this could gain some extra stability and performance if that's the case for you.
@@M4Looney well...on time Spy i Lost around 100 point vs 22.11.2, from 18k score GPU to 17.9. seems to keep same settings (2480 2150 FT 900mv)...i try to let memory 2150 without FT as u say but i Lost another 70 80 point, pull up voltage on 925 and Lost other points. I dont really care about the best scoore possibile on time Spy, i prefer to be stable with best performance in game. Cyberpunk bench seems to be similar, maybe Better 1% low. I must test other games...
Yeah, seems reasonable. Benchmarks is not as important as games and stability. Here you got a point. I meant you can try 2100 MHz FT VRAM. FastTimings are bringing most performance but at high clocks these may be unstable. Max I can do is 2120 FT but I like the settings more conservatively. My card does 2150 FT but I lose about 5 % performance instead of gaining a few percent making the too fast setting unusable.
Hey, i'm trying to undervolt my 6950xt, but the new voltages don't get applied for some reason. The profile is working, because turning off the DS settings in feature control works, but the voltages don't do anything. I set the max voltage to 1150 for example, but Adrenalin keeps showing that the max voltage is still 1200. Am i missing something?
@@M4Looney Ah yes, i should have mentioned that I reboot my pc (no fast boot) after writing the sppt, but unfortunately it doesn’t change anything. Should i maybe use ddu and redownload MPT or something?
Do i have to tick something in feature control before it works perhaps? Ive seen other people use the temperature dependant voltages instead, but i’m not sure if that is something i should use.
Ok, then Idk. Which driver are you using? Maybe they patched it. So, doing a DDU seems right. Maybe this helps. Maybe using a new MPT version or using an older driver might help.
Idk what you exactly mean... In MPT you limit the voltage of the GPU whereas in Wattman you give the GPU the instruction to use less voltage (but the GPU is not forced to use this lower voltage). Wattman undervolt is utterly broken as the UV is just a "recommendation" for the GPU and the GPU will use as much as it thinks is crucial for stability. Only MPT undervolt uses a "real" limit. See my other video regarding this topic. MPT undervolt is just much more effective than Wattman undervolt (20 - 30 W less for same performance). Also AMD unfortunately locked / encrypted SPPTs for RX 7x00 cards which means undervolting becomes useless if you want to actually limit the voltage. Also one can't increase the wattage and the other parameters like Amps etc. which is very disappointing.
Hi, depends on what you're doing. Without MPT you can't undervolt well since for whatever reason MPT undervolting is much more effective. If you however increase power without increasing cooling that might be the case. But don't modern GPUs have automatic shutoffs if the GPU is overpowered or overheating? I now got an HP Omen 16 and desperately want MPT for it (7000 GPUs are not supported and igpus, too). I just want to be able to tune it... From a (power-) user perspective that's just one more thing that is forbidden bc there might be problems. I don't like that: why take people's freedom? Greetings
@@M4Looney Thanks. The Best I could do is 2290Mhz at 920mV. Have you tried any DX11 games? I have noticed that those games make the GPU use far More power than DX12/Vulkan.
Today I tested 2400mhz at 900 mv, and it work stable. But temp on GPU 69 and noise on coils. For now i switched to 2224 at 900mV and change fan settings. Noise gone ;) Rx6800 is very good card.
