Guys, i am rocking 3x R9 390's and i can't seem to troubleshoot it anymore.

Issue:  Getting the GPU returned incorrect data!   Message which freezes the system rendering further mining useless.
Happens sometimes after 30 minutes and sometimes after days.

Seems to happening to GPU0 the most but i switched the GPU's to no avail. Installed all sort of drivers, no avail.
Even removed a troubling GPU and then it seems okay and after some time it appeared again.

Read something about people power limiting GPU's to prevent this, any ideas ?
Any specific drivers recommend for the R9 390 ?

Btw, running Win7 64, using Nicehash Legacy but the system will also hang using claymore mining when mining any other coin.
I do NOT care about electricity, just want to have a stable system.

Who can shed a light on this please ?
