Slowly getting some where, I'm currently just running 2 cards a MSI Twin Frozr 7950 and a 7850 with another 7950 on the way, Ive been playing with voltages mem clocks thread concurrency etc, only to get about 540kh out of the 7950 , but now got it to 640kh and on 1.1v.
With the 7850and 7950 minng about 935kh havent tried tweaking the 7850 card since its my display card.
Ok heres my settings if anyones interested -
I use Sapphire Trixx for setting GPU speed and volts to -
7950
1017 gpu clock
1500 mem clock
1100 vddc
stable no rejects at 74c
7850
900
911
1032
stable at 69c
And running this batch file -
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
D:\Downloads\cgminer372\cgminer.exe --scrypt -o http://gld.cryptcoins.net:5533 -u xrturbs.1 -p 1 -o http://ltc.give-me-coins.com:3333 -u xrturbs.1 -p 1 -I 20,16 --thread-concurrency 24000,17000 --lookup-gap 2 -w 256 --gpu-powertune 20
It's a start, got the third card on the way and another psu, looking at aluminium frame and pci-e extender cables to go to 4 cards soon
Oh and shes current pulling 540w from the wall using a corsir gs600 psu, have a 850 on the way to run extra cards
