Intel dualcore cpu 2.7 GHZ
Using 14.7 drivers,tryed also 14.6,14.2 and i only didnt checked 14.11
Also tryed win7 64bit,win8.1 64bit..
I have also powercolor r9 280x but i dont have problems with them.
SO 4 R9 290 TDHE WITH H61PROBTC,1300 EVGA G2,4GB RAM,CHINESSE EXTENSION CABLES,
I m keeping them on 85-94 temperatures on x11 sgminer,checked a lot of versions...
from 3 - 5.1
They mine fine,but the question is why i have so much problems, from 15 machines i got problems with 8-9 of them / sick/dead/freeze/blackscreens?
Somebody tryed that cards?
Any opinions?
Thanks
