Hey guys,
a couple of us have been mining altcoins for a while now and i have been messing around with settings but cannot seem to get over 680kh/s per card!!
Info on the rig:
4x gigabyte 7970 GV-R797OC-3GD rev2.1
8gb Ram
Processor AMD FX(tm)-4100 Quad-Core Processor, 3612 Mhz, 2 Core(s), 4 Logical Processor(s)
Motherboard
Running windows 7 64bit.
I am running cgminer 3.7.2 with the following .bat file (after trying various combinations, this seems to give the highest hashrate):
setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 timeout /t 180 C:\Users\Miner\Downloads\cgminer-3.7.2-windows\cgminer-3.7.2-windows\cgminer.exe --scrypt --url stratum+tcp://eac.us1.hackshard.com:3333 -u x -p x --intensity 13 --gpu-engine 955,955,971,971 --gpu-memclock 1500 --thread-concurrency 8192 --auto-fan --worksize 256 -g 2 -v 1 --lookup-gap 2
Can anybody see something i am missing that is denying me the 700+kh/s that people seem to be getting?
Any help is greatly appreciated!!!
Thanks
