Hey guys, so I got my 3090 Ftw3 from step up and played a bit around with it. When I set my card to 119% Powerlimit = 500 Watts the boosts starts at 1965 mhz and goes down to 1890 mhz fast as soon as the temps rise. I know 1890 ist more than the advertised 1800 mhz but dang, from a 500 watts i expected the card to boost to around 2010 mhz and going down to around 1950 mhz when temps rise. Overclockingwise i can't go past + 120 on core in timespy which results in dissappointing 2055 going down to 2010 mhz when temps rise and the memory doesnt go further than +500 also very disappointing. I already tried undervolting and the card cant even manage 1860 mhz @ 0.9, i have to go down to 1800 mhz @ 0.9v. I have never had such a bad 3090 till yet. Also I have never seen the card using more than 470 watts. In games its most of the time around 430 to 460w (playing in 4k) Has anyone else had such a bad card? Other cards I had could easily hit 2100 mhz or more and +1000 or even more on memory. Is Nvidia keeping the good chips for the 90ti and only puts chips on 3090 or is there something else going on with my card?

Thanks, so my timespy graphics score is 21505, my previous cards had more or around 22k graphics score there. Perfcap reason is PWR even though it never shows 500 Watts. It already shows pwr at around 440 Watts. Pcie Slot never saw more than 66 Watts so it runs within specs. GPU Temp max was 74 degrees in Timespy with fans set to 100 percent . In Games it reaches 78 - 80 degress with 119% Powerlimit and stock fancurve

In afterburner i set + 105 core + 500 memory (anything above crash) +120 is only possible with no memory oc.

In games + 90 core is stable, everything above crash

Nvidia Driver ist the newest available
Control P settings in Timespy was prefer max performance

Roomtemp around 23 degrees

Memory Temp never went above 80 degrees.

I have my 12900k running stock with only xmp enabled for the ram

I can make my kingpin pull more than 470 watts but the card slows down , your card seems to be average and you had good samples before

Is your Dominator 6200 C36 100% stable? I couldnt get mine stable at all at that speed....one day it would pass Memtest and the next day would fail.
Also when it did pass Memtest I would get random crashes gaming.
 
The Dominator Kit I have running at 6000 C32 and is rock solid stable.
Check that it is 100% stable or try setting to default 4800 and then play with GPU OC'ing.....

I dont know if its stable, memtest had no errors for me so i believe yes.

Can you show me a picture of your 6000 cl32 settings please :)

I wouldn't worry too much about GPU memory OC for games, it does VERY little. Also, I've noticed Afterburner seems to want to crash 3D mark when messing with memory OCs. I never have both programs going at the same time when setting memory speeds and it helps greatly.

It's likely crashing when load drops and clocks jump up. Limit the maximum frequency. If I were you, if start at the stock max frequency of 1965MHz. Do like +150 on the offset, apply it then go into the F/V curve and flatten the curve out once it hits 1965MHz. If that's stable, push the offset higher but keep it capped at the same max frequency. If it's not stable, lower the offset and try again. There are quick ways to do this, reach point does not have to be set individually.

Doing this will minimize power use and temperatures, which will keep the boost clocks high. It will outperform stock settings while using a lot less power and run a lot cooler. You can use this same setup too go higher max frequency, but it will be diminishing returns.
