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 BIOS versions although I am not sure which BIOS to flash with since i have a OC model and I have read that is not the best for scrypt mining hence needing to try a TO??
My current config for cgminer is :
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
As I mentioned I tried -g 2 as suggested from everyone and every time it drops dramatically down to 380 Kh/s from 540 when using -g 1. When following the ReadME file for Cgminer my ThreadConcurrency speed came out to be 22400 but have read to use 8192 and see no difference in speed between the two. So at this point I am thinking a flash of the bios will be the way to go although I am still up for hearing anyones suggestions Thanks for the help in advance! this is driving me crazy..rawwr
if it come with f72 bios you can flash it with 7950 f43 bios an it can run 730khs @ 1040 1250
Not sure what F# the original Bios was but it was this : BIOS 015.022.000.004
Which do you recommend me going to in the end? and do you possibly have a link so I can flash that now before going forward?
I found this link but do not see a F43 : http://www.gigabyte.com/products/product-page.aspx?pid=4102#bios
I see a F3, F72, F41_A and f2.
There is also this link with more Gigabyet cards. I do have the r79703GD model

Basically it looks like i kind of have two options in Bios picking..a 1100/1500 or 1000/1375...any ideas on which would be the best to continue my testing? Thanks!!
it is 7950 bios
to check f# use gigabyte utility
so for a 7970 then a F43 bios is a no go? right now i am running stable at 640 kh/s with a 925/1000 but running temp at around 83/84 so higher then i would like. Anything above a 940 engine seems to go black screen. Going to do some more testing tonight and keep the good fight coming..at least i am out of the 500's now..yes!
