Title: 4th GPU dying - Sapphire R9 280X Dual-x Post by: mgscs on February 09, 2014, 10:06:09 AM Heya!
Just expanded and added an exact same setup. Everytime I start cgminer after 2-3mins the 4th GPU dies - I get the message "driver has stopped responding and has recovered" and the 4th GPU becomes a CPU miner. If I disconnect 4th GPU the same thing happens to the 3rd one - which is fine when 4th is connected....

Title: Re: 4th GPU dying - Sapphire R9 280X Dual-x Post by: Much_Hustle on April 13, 2014, 11:47:46 PM I'm having the same problem! Have you found a solution? I also have G3220, Biostar H81S2, Ram 8 G PNY, Windows 8.1, AMD 13.25, 6 7950 GPU (2x MSI R7950 TFIII, 2x PC AX79503GBD5 2DH4, 1x Sapphire 11196-16, and 1x AMD R7950 Reference), Corsair AX1200 and CX750M.
Didn't used to do this before, but I had different problems (windows not seeing more than a few GPU). I've done more clean installs than I can count, it's very frustrating. |
