currently im running 2x saphire nitro R9 390 im undervolt to -15% and overclock to 1100mz no mod bios and running perfect at 31mhs
if i mod my bios what i get ?
For my own mod, I run the R9 390 below 1000mV, but the Core/Memory is just 975/1000 MHz, so the hash rate is just 27.4 MH/s.
You might need to mod the memory strap timing.
I heard the Eliovp has modified the Sapphire Nitro cards in the past.
