For those asking, when benching Forza Horizons 4 i was drawing @ 430w from the socket.

Thanks Dusty. What is your PSU again?

Thanks Dusty. What is your PSU again?

I'm running a good quality 750w - that is a few years old.

And to be fair, I'm getting a little bit of coil whine.

 

[Chewie]

No coil whine to report on mine, running with a Seasonic Prime Titanium 1000W.

Any experiences temperatures wise on your end guy. Mine runs really fairly hot (78C-80C GPU core & 95C GPU junction) while still remaining quite silent and perfectly fine in terms of performances but I'm a bit worried on the long run. I've tried to tweak the fan curve via Wattman but it doesn't seem to take effect.

Like for instance I set it to run constantly at 50% fan speed (just to test), I launch a Time Spy benchmark and when I look back on GPU-Z it shows that the max fan speed was 43%

Perfectly normal, you're 15c below the TJMax for Junction temperature. Undervolt, these GPUs love it if you want ever better temps.

I’m already using the Auto undervolt feature 1150mV instead of 1175mV) but haven’t tried to sure what to go for (not really interested in OC).

You should be able to run a much bigger undervolt than that. Try -0.025mv drops until you hit instability.

 

[Chewie]

But what should I use for the min and max frequencies then, knowing that I don’t want to OC?

Big Navi can overclock and under volt. If stock performance is fine you can just under volt, by a lot!

I was able to lower voltage at stock clocks from 1.150mv to 1.000v without issue on the 6800 XT.

 

[Chewie]

Ok but I still don’t know what values shall I use. The default min 500 and max 2509?

 

[6900 XT]

Try 2300 min 2600 max 1.1v. Tweak from there.

 

[LtMatt]

Try 500-2500 and go from there.

 

[Chewie]

Ok thanks guys, will give it a try.

Potentially stupid question, but do you mean 430W for the card alone?....

I managed to get hold of a 6900xt red devil by luck today then realised the minimum required psu was 900w...........

 

[Jonnym28]

Came in one day! 430/500, not quite number 1

Very nice

Unless i am mistaken Nobody in the world has reviewed a 6900XT red devil so if you can be bothered, buy a £15 socket meter and tell us
