I've tried searching for information about this and didn't really find anything that answers my question. I have all the various drivers installed and am running cgminer 3.7.2 with (2) 7770s (MSI R7770 PMDIGD5) and each card hashing at around 50kh/s (107.5 kh/s avg) and ~75 WU total.

Now, on the LTC mining hardware comparison chart, the lowest hash rate for a 7770 is 143kh/s and I'm not even getting close to that with TWO OF THEM..

Anyways, if anyone can help me get my hashrate up to where it should be I will gladly tip them in LTC or BTC for their effort (which it shouldn't take much of since I'm probably making a newb mistake)

Config file:

cgminer.exe --scrypt -u x.x -p x -o stratum+tcp://multi2.wemineall.com:5555 --gpu-fan 100,100 --gpu-engine 965,965 --gpu-memclock 1425,1425 -I 18,18 --lookup-gap 2 -g 1 -w 256,256 --thread-concurrency 8000,8000

Hardware info from AMD Catalyst Control Center

Memory Size 1024 MHz
Memory Clock 1125 MHz
Total Memory Bandwidth in GB/s 72.0

AMD OverDrive
GPU Clock 1300MHz
Memory Clock 1300MHz
Power 20%
Temp 33C
Fan 100%

PS. I had someone help me set this up and he had me input all those values twice, but I never see people do that so please feel free to tell me it's not necessary.

Thanks a bunch! Smiley
