Hello.
Last week a bought a used Board, the Asus P8Z68, for using my 2 GTX 970 in SLI. HAve a 700 Watt Power Supply. I used to have a Core i5-2300, overclocked him to 3600 Mhz (103,5 x 35).
Today, I got an new, also used CPU, the i5-3570K. And the trouble starts. This CPU crashes, as soon as I overclock it above it´s regular 3,4 Ghz. So in fact it is slower than the 2300. I crashes always at the same Point in Metro Benchmark. It crashes sooner or later depending on the overclock in HEaven Benchmark. In LinX, it run stable for 10 min, a pure CPU Test at multiplicator 41!! And in FurMark, it seems also stable one Round with higher Multipl. as long as I do the CPU Test. When I do GPU Test, it crahes hard within seconds.
The Screen gets Black. The GPU Coolers switch to 100% in the same Moment. They sound like an Airplane, till I press reset. Sometimes System resets by itself. Sometimes, in Witcher 3 colours change completly Tonecurve and screen freezes.
I underclocked my RAM
Sounds like GPU Problems, but happens only when I overclock the CPU.
the 2300 was Sandy Bride, the 3570K is Ivy Bridge. He added PCIe 3.0 to my Z68 Board.
My SLI GTX 970 run now in 8 Lanes @ 3.0 instead of 8 Lanes @ 2.0.
I did not install the Operating System new.
I spended so much Money now for Board, CPU, 16GB RAM (Crucial Tactical 1866) and 2 EVGA 970 (which are also awful to overclock), and now my System is completly over and out. The BIOS is latest.
Please help me. I have no more Idea!
