Hello
just got my self a 3x sapphire 280x dual-x and a PSU thermaltake 1200w gold
at high load when temps reach 80-84c suddenly the screen freeze and cant do anything other than hard reboot the PC.
when i try to run each card individually i see no problem or crashes which make it impossible for me to identifey the problem
tried to downclock my cards from 1020mhz to 870mhz at lower voltage 1.0v, and it was fine till 4 hours later when its crashed again the same way.
some times when the crash accure, one of the card (mostly the problem because of it) suddenly its temp change from 84~ to 511c, which its not for real a 511c otherwise ill had the meat ready for a BBQ, and have seen few posts claiming they have same problem, didnt find a fix in these threads.
at some point i remember the problem solved by its self then later i was adjusting the case fans and re installing them in different location inside the case, then after i powered my PC the problem came back again, and this problem are driving me crazy, cant understand a thing about what happening exactly.
tried flashing diffrent bios
tried clean install my drivers, tried both 13.11 beta and 13.12.
tried disabling ULPS
tried enabling constant voltage to GPU
my PC spec:
i5 3570k
Sabertooth z78
PSU: Thermaltake 1200w gold
16gb RAM 2133Mhz
