And its on in Windows and fullscreen and then applied first? And still no option like the screen shot I sent you? That's bizarre.

In the xml change window mode to 0

Yep. The value is already at 0.

I've given up now, I'll just settle for the higher averages of DX12 and hope that Rockstar eventually fix it.
 
I ordered a 6900XT early this afternoon …….when they were showing as in stock......and of course now they are out of stock and Im still waiting for confirmation of dispatch (confirmation of order was around 2pm)

I was feeling a little guilty paying so much for a gpu…..and a 5800XT......and a gaming chair....but I will be gutted if I missed out again (after missing out on 5800 on day of release , and then just getting what looked like German popups while trying to pay for 6800XT on day of its release)

Gibbo removes them from sale so you might have one, just have to wait and see or ask him directly @Gibbo

Good evening, a day ago I received my new 6900XT (reference model) and I would like to know if any of you have a good profile for this graph (voltage, speed of the gpu core ...) I await your response, a greeting. I have this config. Something to change?

Hey.

I created some 6900 XT GPU Tuning profiles that you might like to try. You can just load them into GPU Tuning and away you go.

2300Mhz/2012Mhz 1.025v Power Saving 255W
2400Mhz/2112Mhz 1.050v Balanced 275W
2500Mhz/2112Mhz 1.100v Performance 300W

I can vouch for these, very good profiles. Using Balanced at the moment, silent, but fans climb at a good rate when you need it.
Better than stock.
 
Getting ready .. Waiting for the water block..

Did some memory performance testing in Red Dead Redemption 2 and again i saw the behaviour play out as i mentioned before, 2112Mhz appears to be the sweet spot, at least in games.

Testing was done using the built in game benchmark.

2160P
RDR2 DX12
Ultra Settings - Tree Tess Off, MSAA/Reflection Off Water quality High, Refraction/Reflection 3/4.
TAA enabled and sharpness 100%
5950X PBO
6900 XT 2270-2370Mhz Undervolted to 1.000v (actual in game core clock is minimum of
2300Mhz, peaks up to 2325Mhz)
Fast Timings On
21.2.2
No MPT, using default board power limit 289W+15% power limit so no chance of power limit affecting results as power draw was 220W-240W ish according to HWINFO64.

2012Mhz Memory Clock

2112Mhz Memory Clock

2150Mhz Memory Clock

This behaviour in memory clock performance has been the same now on 1x6800 XT MBA, 1x6900 XT MBA, and 2x 6900 XT Mercs.

Don't run your memory at 2150Mhz when gaming folks, you are possibly getting stock levels of performance. In synthetics you can crank it up to 2150Mhz and see gains, but games seem to see reduced performance back to near stock levels.

Is that with default or fast timings?
 
The Vram has error correction so if you increase the frequency too much, error correction will kick in and you will get worse performance than you get at lower frequencies. That's why you need to test it in more games to see if the 2000MHz or 2100 or 2150 or whatever is the sweet spot.

I've tested it in Far Cry 5, COD MW, Red Dead Redemption 2 and all showed the same behaviour.
