I think I am ready to flash my bios but need a little help. I have a Gigabyte HD 7970 3072MB GDDRS and have tried everything but no luck getting past 550 Kh/s via scrypt. I am thinking my BIOS may be too old on the card as this is my current stats on windows 7:
Display device : AMD Radeon HD 7900 Series on Tahiti GPU
Display driver : 9.14.10.0969, Catalyst 13.4
BIOS : 015.022.000.004
GPU: Gigabyte HD 7970 3072MB GDDRS - GV-R797OC-3GD
Looking at
http://www.techpowerup.com/vgabios/index.php?manufacturer=Gigabyte&model=HD+7970 there seems to be much newer ones although I have never flashed a BIOS or anything for that matter so maybe I am wrong? My current settings are :
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -w 256 -g 1 --thread-concurrency 8192 --intensity 13 --gpu-engine 1100 --gpu-memclock 1500 --gpu-fan 100 -o http://mining.usa.la.hypernova.pw:9332 -u worker.1 -p xxxxx
I have tried -g 2 and every time it drops dramatically down to 380 Kh/s from 540 in -g 1. I have also followed the ReadME file for Cgminer and my ThreadConcurrency speed came out to be 22400 but have read to use 8192 and see no difference. So at this point I am thinking a flash of the bios will be the way to go. What do you think? Thank yoU!
