Apologies for using English, my Duetche is horrible.
Information in this thread has been very helpful, thank you everyone.
Results can be seen on 3Dmark ORB as Claviger. All results with water at 4c-6c, Liquid Metal, Bykski Block, ~7 liters/minute flow, MPT only, all power saving enabled, all safeties enabled.
At up to 680 watt draw temps are these or less:
Core temps ~30c, Hotspot ~ 50c, Memory ~35c
6950xt OCF ASRock:
Using FCLK 2300 in all 3 spots.
Using 1100 SOC speed max, 450 min speed.
For FT2 @ 2360 I need VDDIO 950mv, MVDD 1500mv, TDC SOC 140a, SOC min 1050mv, max 1250mv.
For FT1 @ 2420 I need VDDIO 925mv, MVDD 1475mv, TDC SOC 110a, SOC min 1050mv, max 1225mv.
More MVDD than 1500mv shows no improvement for me.
Using vGPU min/max of 1100mv/1325mv
For TS/TSE Wattman Clocks: 2800min 2990max
For FS/FSE/FSU Wattman Clocks: 2820min 3050max
Raising vGPU min/max to 1200/1350 gives more clock speed, but I have not benched like this yet, waiting for EVC2 for high power testing.
Raising min clock and lowering max clocks to narrow gap to 100mhz is less score and less stable.
2800mhz min +/- 20mhz always gives best results for my card.
When EVC2 arrives I'll be shooting for 2900/3100 round of benches, sometime next week with 1.3vgpu actual, not VID.
When test week is done for me in a few weeks I'll make another 3dmark run, have learned a few tricks recently I had overlooked
