Hi All,
I've been running the following rig for a month with no issues:
Mobo:Gigabyte GA-990FXA-UD5 R
CPU: AMD 4-Core FX-4100 3.6G 8M R
RAM: 4GB (can't remember which, cheap sticks)
HDD: 60gb Corsair Force 3 SSD
OS: Xubuntu
GPU: (2x) Gigabyte GV-R7970C-3GB HD7970 R
PSU: Corsair HX1050
Miner: cgminer
Mining LTC I am seeing a consistent 715kh/s per card, so all has been good.
I have also been running a third Gigabyte GV-R7970C-3GB HD7970 R on a separate box as I could not run all three without serious heat issues on the first, I as seeing 715kh/s as well on this card.
I finally picked up a 16x riser and last night I built a frame to hold the card up, and support my ghetto fabulous cooling system...WalMart box fan :-)
I have it running (about 24hrs now) and the riser seams to be working without heat issues of its own but I have not been able to drive the hash rate past the low 500's per card.
So my question is, is the lower hash due to a power issue, is the 1050 just not enough? Is it a config issue? Or is it something else I am missing completely?
Any and all help will be most appreciated
