I acctually found out the undervolting was the problem... or Sapphire Trixx rather. reseting clocks etc made everything stable so it's trixx thats crashing my card

You were having the problem after under volting the cards?

Yea. I reseted them with TRIXX again and rebooted computer and everything has been running fine

Be careful whenever you undervolt.

Careful about what? Never underclocked before only overclocked so new to this business ^^

Flashing a custom BIOS with modified clock speeds, voltage and fan profile is the most reliable method in my experience.

You haven't undervolted?

900-100W from wall seems impossible for 4x 280x. I run 1100 from wall with undervolts from 1.200v to 1.143v on each card.

Depends on how far you undervolt. Some of our Gigabyte 280x Rev2 could undervolt as low as 1.01V @ 1040/1500, and our 5 GPU rig would pull 1250W at the wall. If you were to take out one of the GPUs, I bet you it would pull just a hair over 1000W, maybe 1020W?

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....

Windows 8.1
Corsair AX 1200i Digital 1200W 80+
Sapphire Radeon R9 280X 3GB DUAL-X OC x 4
Corsair 4GB (1x4GB) CL9 1600Mhz VENGEANCE
Intel Pentium G3220 3.0 GHz (Haswell)
ASUS Z87-PRO ATX
120GB Sandisk SSD

14.1 Driver - Tested with 13.25 aswell no improvements.
CCC disabled
Reformated comp. no fix
Pulling 900-1000W from wall

Help me out please!
