Then you have to experiment with the OCs, try 75% Power, -200 Core Clock, +1200 Memclock.
for more than 100mhs on 3080, it needs around 1400-1500mhz minimum overclock on memory, my 3080 10gb evga ftw3 I have at 1500mhz overlock on memory and get 103mhs, memory temperature is around 76c and core temperature around 55c.
HI, tks for the guidance 1st. But i have tried to adjust to memory to 2000 before, but the hahrate seem is nothing diff, my current core temp is around 55c but the memory temp is higher than yours which is around 88c.
