yea u have 4 bios on mining cards
check the end of the pcb below the 8 pin
should be 2 dip switches
if not ill check back and grab u copy of one of mine
i dont remember how they are classified tho between the 4 dip switches a search will prolly help with that
i flashed whatever bios it was set at when i bought them
backup the current bios
then modify that bios
copy 1500 memory strap to higher straps (1750,2000,2250,etc.)
and see if it increases your hash
Been there, done that.
I get to 1850 mem clock and 26.7 Mh/s. Anything above that, I get errors.
yea thats the wrong strap way too tight prolly 1425
srb bios tool should be able to auto strap ur bios as well
it uses custom straps pulled from all mem manufacturers
