I believe it's due to the 2 second update interval or something. Still trying to figure out the whole OC settings thing. Set mine to 1802 (950mV), 1150 mem - and yet the wattman graph shows peak of well over 1800 gpu speed and well over 1200 mem after playing a game. Don't know how accurate all this status reading is in wattman, or how the overboost thing works?
Nice and quiet card playing RE2 in DX11 mode, but when I switch to DX12 and up the model quality beyond 100% fans ramp up really quickly and get's noisy. RE2 setting shows used memory in yellow stating "memory usage high, might cause instability" even though it's a lot less than the 16GB available. Game/driver bug?
It's all early days so think it will take a while to get the best out of this card.
