I'm not too sure about that card tbh. The BIOS flash is not to put a more up to date BIOS on, but to put a different BIOS on which doesn't suffer from the low scrypt hashrate. As i say this is a problem with certain cards, usually the OC / Ghz editions.. Just to confirm, your card is a normal Gigabyte, not OC or Ghz edition or anything?
Try the following and let me know what hashrate you get: -s 2 --thread-concurrency 20992 -I 13 -w 256 -g 2 With 1040mhz/1081mV GPU and 1500Mhz/1500mV RAM.
*Edit - reading your post more closely, am i right in saying you have an OC edition card? If so then i'm pretty sure a BIOS flash to the non OC version would work.
Also if anyone's interested, my 7970's use about 250w each at these settings.
Yeah am pretty sure it is an OC version from these numbers :
GPU: Gigabyte HD 7970 3072MB GDDRS
GV-R797OC-3GD
Display device : AMD Radeon HD 7900 Series on Tahiti GPU
Display driver : 9.14.10.0969, Catalyst 13.4
BIOS : 015.022.000.004
Do you know how to flash the card or what BIOS to actually flash to as there are so many to choose? this will be my first time flashing but am confident I can make it happen
