Bought a second Toxic 280x as my first one performed brilliantly,unfortunately the second one has Elpida memory and i cant seem to get a decent hashrate from it
The first one with Hynix memory can hit 800kh no problems,but the new one struggles to keep a steady 650.Also when i use them both together the new one seems to drop the first one's hashrates to below 700.
I just dont know what i'm doing wrong,the bios of the new card is 015.043.000.005.000000 and i have tried to flash to previous bios but i only get black screen upon a reboot of the pc.
i've tried individual bat files for each card with different settings,i've had both cards on the same bat file,i've switched cards to different pci-e slots,but nothing really seems to be giving me any improvement.
Does anyone have any idea what i can do?
Another thing i noticed is that my main pci-e slot seems to be stuck at x4 when it should be at x8,tried resetting bios,reseating the card etc with no joy,my mobo is a maximus formula vi.
Cheers for any advice.
Nikkers.
