Hello,
I have problem.
Who can help me?
I have mining rig hardware:
- 4x XFX7950 FX-795A-TDJC
- ASUS SABERTOOTH 990FXR2.0 motherboard
- 8GB RAM
- CPU AMD FX8320 8x Cores 3.51 Ghz
- PSU Lepa 1600W
Software:
- Windows 7 SP1 x64
- AMD Radeo HD drivers 13.4 x64
- AMD SDK 2.7 x64
- CGMINER 3.3.1
My cgminer.conf
"api-allow" : "W:127.0.0.1",
"api-listen" : true,
"api-port" : "4028",
"expiry" : "120",
"failover-only" : true,

"lookup-gap" : "2",
"shaders" : "2048",
"thread-concurrency" : "21712",

With this configuration 3x GPU cards running stable. But when I connect 4 card and run cgminer works very bad and turnoff motherboard. But PSU still running.
Who can help me with this problem? Maybe not impossible run rig with 4x GPU's? Maybe my configuration is wrong? Or I forget something to install?
Than you in advance,
