I am using the latest miner and this is my bat file
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
COLOR 0A
del *.bin
cgminer.exe --heavy --vote 512 -w 64 -o stratum+tcp://hvcpool.1gh.com:5333 -u x-p VIP -o stratum+tcp://hvcpool2.1gh.com:5333 -u x-p VIP -I 8 --gpu-memclock 1400,1600,1300,1300 --gpu-engine 1000,1100,950,950
The GPUs are as follows 7970, 280x toxic, 7950, 7950
I am getting around 10MH/s each of these... any ideas? I thought I should be getting 20MH/s each?
I am using the latest miner with the 13.12 installed
Lower the memory clock on the 280 to 1500Mhz, increase GPU clock on the 7950s to 1000Mhz, try a different worksize, add "-g 2" for multi-thread mining, try "-X 4" instead of "-I 8", add "--thread-concurrency 8193".
My 7950s run 1050/1450 at ~15Mh/s
My 280s run 1100/1500 at ~20Mh/s.
