Hey guys, I've just gotten these two new gigabyte 7970's and they're posting hash rates of around 600kh/s each. (See screenshot below)
I have configured other 7970's to be around the 720-750 mark in the past, but this is kind of underperforming for what I was expecting from the gigabytes.
In GPU-Z they show up as Radeon 7900 Series, and my GPU usage is 99% on both cards, not to mention the heat is around 86*C for GPU 0 and 78*C for GPU 1.
I have cleared the bin files as per this
readmecgminer says that my thread concurrency should be 22400 (as per what was selected and put in the bin filename)
Here's my .bat file
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o stratum+tcp://stratum.wemineftc.com:4444 -u maursader.1 -p x --shaders 2048 --intensity 13 --worksize 256 --thread-concurrency 22400 -g 1 --gpu-engine 1100 --gpu-memclock 1500 --auto-fan
Please let me know your thoughts, as this has been driving me up the wall! I removed the look up gap because I read that it sacrifices hashing power on the first GPU.
Cheers
Ps. For hardware, I've got a gigabyte am3 motherboard with the phenom x2 945 black edition, 12 GB DDR3, 750W antec power supply.. etc.
