Sammelthread Big Navi RX 6700XT/6800(XT)/6900XT Overclocking/Undervolting

How do I know if my card is dying? Now, no matter what settings I use that had previously passed Time Spy, are all crashing at GT1.

 

[GerryB]

reinstall 3dMark and Adrenalin and MPT
test@stock without MPT

CPU+RAM = no OC/UV

I think my card is degrading; I have to use like 10–20 MHz less clock speed than before on different voltage levels. Would changing the thermal paste help at all? I asked other people with Gaming Trio cards, and mine is way too hot.

How hot 🔥 will it be at the hotspot, Vram and GPU? And at which RPM?

Just so happened to be my highest score; maybe because I ran the test as soon as I opened my computer so temps were cooler. I used to be able to pass with 2625MHz at 1075mv now it barely passes at 2600, so I did 2595 for this test.

DDR5 Temps seem fine at 7200 with tight timings around 55ns in Aida 64.

The Chassis1 fan is a 40mm Cooler Master fan I have bringing air out of the side of the GPU heatsink. My 12700k is undervolted by 100mv with a 140mm AIO.

Illustrative example of Chassis1 Fan.

When I asked someone about their temps on a few-month-old 6900 XT Gaming Z Trio, they said those temps. Which are A LOT cooler than mine. The temperatures shown by my TimeSpy result in HWINFO are slightly cooler than what I see in game.

 

[GerryB]

may be, after some hours gaming
the airflow is too bad

If you want to repaste, try to get the new Honeywell-Pad:

works good with the bigger 7900xtx

How would that do compared to regular thermal paste on the Gaming Trio? Since the mounting is awful, there are big gaps between the die and the heat pipes. I guess since Navi 31 is Chiplet it helps get between the gaps, but the XFX cooler its being used on has a flat contact plate.

Also, how big are the thermal pads in case they rip when opening up the card? Or should I just RMA since it would be hitting a 110-degree hotspot at default?

 

[GerryB]

I would try to run the GPU hot, that brings the Pad to work, then very fast the graphiccard out and the screws a little bit more tighten.

generally a pad is no problem, look at the 6900ref.

btw.
why not additionell fill the small gaps between the pipes with liquidmetall or good paste

 

[Evgasüchtiger]

Why not just run the card with human tact and excitement. I would only use these clock rates and tensions with a wakü. Fuck the pair of frames, but quiet and cool 😎

I paid for the whole card, I want all the performance

@GerryB Do you remember what size the thermal pads were from when you repasted your card ?

 

[GerryB]

I use 24/7 only <150W@UV = no need to repaste.
With this it´s near the stock performance.

btw.
+50W =33% more PL gives me only 7,5% more Points in PR
= not really required

Did FT2 end up being unstable for your card?

 

[GerryB]

may be FT2 is useful@6900 but not permanent required@little 6800nonXT
the 6900 needs 33% more bandwidth

FT2 needs a little bit more Volt+Watt and also to get the highscores a little bit more fclk+soc with also more Volt

but in real games with Fps-Limit+Upsampler+FG/AFMF, there´s 24/7 no need of the highest bandwith
What to do with this Watts?
I decided, to use a "slower" setting with a little bit more GFX-Volt+Clock because FG/AFMF needs more Shaderclock-Boost. This actuell 2275MHz is my default maxClock, but with good UVing@GFX+SOC/fclk+Vram.

example 2+3 without fps-limit to show what´s possible@custom inGame-Settings with the 150W-MPT
example 4 with fps-limit = RTSS 59fps means AFMF 118fps, ... stay´s cool+quiet

 

[cra3khead]

This actuell 2275MHz is my default maxClock

Wouldn't undervolting cause you to achieve 60Mhz less due to the undervolting than the effective clock would be at stock though? Wouldn't you have to bump up to like 2340Mhz to have the same performance as stock?

 

[GerryB]

The real game clock depends mostly@PL+Temp: -->the max eff. clock@launchreview = eff.2215MHz
therefore maybe the UV@GFX and SOC+fclk+Vram helps enough

also the effect of Vram-OC+FT helps to reach the same Fps
and
there is no temp-throttle@my UV-setting <60°C Hotspot!
I don´t know the SOC temp but should be <50°C.

look @temp-throttle with a XFX in example 2
seems@default-Bios to be locked @90°C Hotspot as throttle target temp
the fan-control of the XFX use Hotspottemp !

you can try moore target temp with the Trio
MSi use GPU-Edge as targettemp:

try to test with open case at the morning with low ambient temps
may be with 275W you can reach the same clock as with 281W in Kombustor
(run the light GL-Test some Minutes, it has a good boost clock like Gaming with Upsampler+FG/AFMF)

example 3
with my 24/7 fan curve @"closed" case it works <60°C Hotspot and <50° memory Junction (x)
(with distance sticks between glass to case, ... should work like a open case)

may be <50°C memory helps to have less failure correction

 

[cra3khead]

therefore maybe the UV@GFX and SOC+fclk+Vram helps enough

also the effect of Vram-OC+FT helps to reach the same Fps

Should I just keep 1050mv/2565Mhz and bump up SOC to 1025mv and FCLK to 2000Mhz to get more performance then, or would the increase in fps be negligible?

 

[Evgasüchtiger]

Try a little less tension and tact. I would try with 1000mv GFX in the MPT and in the driver to set the max clock to 2480mhz mhz and nail PL in the MPT to 250w

 

[cra3khead]

I don't think that would work on my card though. I can only do 2500Mhz at 1025mv I'm not trying to go below 2.5Ghz.

 

[GerryB]

Try a little less tension and tact. I would try with 1000mv GFX in the MPT and in the driver to set the max clock to 2480mhz mhz

a quick view to other optimized Settings with this voltage
Bread can run maxClock 2352MHz@993mV
Lyero use maxClock 2360MHz@1000mV (x)

edit: may be, your good 6950 can run maxClock 2475 with this voltage, because of per part curves!?
or my little 6800 (see example 3)

and nail PL in the MPT to 250w

230W should be enough to reach 6900ref Performance

(x) The new Ideas of Lyero are interesting!
He runs the Vram@Standard Timing with very good UVing.
and low SOC+fclk, ... needs less watts !!!, ... may be lower soc helps at the temps also!?
With this less Watts he scores very good in TS, ... >6950ref
(the example 2 shows the Fps in GT1+GT2, so the advantage of ST/FT1 is checkable)

I doubt they run those settings 24/7, though. I've seen Bread's 250-watt efficiency score of 22,600. I wish my card was that good; the best I've gotten was <22,400 at 281 watts. I'd run his setting with no complaints. My vram is also bad, so I doubt I could go that low with the voltages. I had tried to previously, and although it was stable during a benchmark, the score was down by a noticeable amount.
