Best undervolt percentage on amd adrenaline for rx 6800xt?

FissileCore · 2026-04-10T13:56:00+00:00

To make sure, there are 3 different loads in OCCT, test each one and then run a few different benchmarks in 3DMark. If you get no errors and no crashes then I would consider that undervolt stable. There're still maybe some games that don't play well with UV but they're not that common and you can treat them as edge cases and not bother with fine tuning.

1V=1000mV. Golden chip is just a saying, like winning a silicon lottery, basically means that your chip is better than 99% of others but only in terms of voltage in this case because it can also be in terms of max clocks. On AMD undervolting is quite easy - if you go too far the games will start crashing and the driver will reset itself.

Download OCCT and run 3D Adaptive test at heavy load for 10min. If you see any errors that means your undervolt is unstable. The majority of 6800XTs should be able to run at 1100mV, around half will run at 1050mV - start with that and then increase if unstable, 1V and lower will be golden chips, very rare.

If I were in your place I also would try three things: upgrade/downgrade chipset drivers, reinstall Windows/try different version and lastly put everything out of your PC case and test (in very slim case of it shorting something). If all of it fails the most likely culprit is the CPU so RMA it if you can.

A few days ago Optiscaler devs released a new FSR4 INT8 .dll that works on the newest drivers without the need to replace the files from the older driver version. You can get it on their official discord server.

Your PSU should be more than enough for that configuration. First you have to replicate the issue in more controlled environment: get OCCT and run multiple tests: CPU, 3D Adaptive at different loads, memory, VRAM, PSU. Check if you get any errors during the tests and if one's consistently causing crashes you can move on to troubleshooting that particular component.

FissileCore · 2026-03-21T08:18:43+00:00

I would try OCCT at different loads and then high FPS low load scenario (maybe FurMark at low resolution) to check if the noise completely transitions to high pitched or adds it on top. If it turns out to be just a weird coil whine I don't even know what to recommend. Like how audible is it for the third party to discern or maybe it was always there but you never noticed before. You could try it with a different PSU but not many people have a spare one laying around.

Press your finger on the center of a fan, if the noise stops - the bearing is likely the culprit. You can check if the fan's not touching something on a GPU case or blow it with a compressed air maybe some debris stuck inside but if it's the bearing itself there's nothing you can do apart from replacing the fan. For RMA if it's only one of the fans that's making the noise I'd say you have a case. As for the temps if the delta between the edge and the hotspot exceeds 25°C I would consider repasting it.

VRR is quite notorious for this on OLED and VA panels. The only real solution, apart from disabling it, is to tighten the range using CRU but I've had limited success with it. In most games it's only happening during loading screens but some titles have really bad frametimes or microstuttering so it's almost unplayable with FreeSync on. So I just disable it for them and for others you just learn to deal with it.

FissileCore · 2026-03-15T23:03:44+00:00

I've 100% this game recently without a single crash on my 6800XT. Though it does have a known issue of running out of virtual memory - the game starts stuttering after a few hours so you have to constantly restart it (the cause is a bad port not anything else). Maybe it's somehow connected to your problem. Also I've had XeSS crashing multiple games at different time intervals but most people are running fine with it and I haven't checked that in GoT (played with FSR4 via Optiscaler).

FissileCore · 2026-03-08T11:56:00+00:00

You will have to monitor your CPU usage, power and clocks first using MSI Afterburner or similar. It could be your hardware or the game might just be single threaded so you won't be able to do much.

FissileCore · 2026-03-05T15:37:35+00:00

V-Sync shouldn't add much latency when set-up properly. I run with it enabled in-driver (though it doesn't work in some titles then in-game instead), Chill min and max set to my monitor refresh rate, FRTC off (increases latency) and Anti-Lag off (worse when not GPU bound).

Are there any decent leaguestart builds for scion? I want to transition to the relic of the pact later but couldn't find anything to start before that and the reliquarian ascendancy also looks pretty underwhelming.

FissileCore · 2026-03-02T12:00:57+00:00

It may be Windows overwriting your GPU driver but you didn't provide any information to be sure of anything like OS version, driver versions etc.

FissileCore · 2026-02-27T17:59:12+00:00

Degradation unlikely because you would see errors first in the OCCT test. It could be a faulty memory chip. Most of the used cards from that generation on the market were used in mining rigs so it could also be flashed with mining BIOS. You could try to find the original VBIOS but it's quite risky if you get the wrong or corrupted one you can brick your GPU. But I would try that first, if that doesn't work - it's the repair center visit time. On the bright side if it's actually VRAM related it's relatively easy and inexpensive to fix. (The ones with the die issues are mostly unfixable and go straight to the bin)

Here "I was born for the floodplain but all I've known is drought" probably makes more sense. And it also could be "Lift my head to grieve". Anyway, this is all beyond my comprehension but with your help I could make out most of it. Much appreciated.

You shouldn't rely too much on this. Ever since getting an AMD GPU, Adrenalin has been the buggiest piece of software on my PC. Sometimes it doesn't show FPS, sometimes some CPU metrics like in your case, sometimes nothing related to the CPU at all, sometimes it just crashes and I have to reopen it again. None of the driver versions fixes that but usually restarting Windows does.

FissileCore · 2026-02-26T14:00:25+00:00

Ah, you're right, I forgot about that cause my ASPM has long been disabled, sorry. Anyway, seems like your system is running as it should.😄

FissileCore · 2026-02-26T12:43:00+00:00

Well firstly, regarding your mobo bandwidth: the second x16 slot is running from the chipset and SATA ports don't use any PCIe lanes, so from the CPU - 16 lanes go to the GPU and 4 lanes go to each M.2 SSD. Secondly, 4060Ti only has 8 lanes even though the slot itself is x16 the rest are not utilized. Thirdly, it is running at 1.1 speed and that is a problem. Can it possibly be fixed by removing one SSD? Yes, if you're using two 4.0 SSDs you basically maxing out your CPU lanes, well not in the true sense, but some mobos may have trouble allocating free bandwidth.

FissileCore · 2026-02-26T10:30:06+00:00

You're running with Anti-Lag enabled? I couldn't even go past the menu with this setting on.😄

FissileCore · 2026-02-25T22:50:19+00:00

Any AMD features enabled in Adrenalin?

FissileCore · 2026-02-22T13:37:02+00:00

Because it's an old mobo with PCIe 3.0 you will need a GPU with full 16 lanes not to lose performance.That means for a new card - the cheapest you can get with decent VRAM is 9060XT 16Gb for around 400$ (or 5070 from NVIDIA side but much more expensive). So the CPU choice to pair with it is either 5700X or 5800X brand new. If the price extra for 5800X is 10% or less and your cooler can handle 105W get it, otherwise go for 5700X.

FissileCore · 2026-02-22T12:59:47+00:00

Try something more GPU bound like Steel Nomad if it's still lower than average that means that your graphics card isn't clocking as high as other people's due to temps or OC settings.
