I have two ASUS GTX 690s and I was recently testing them by themselves. It seemed that one card overclocked and when I put the same overclock on the other card the system would hang.
System is
i7 3930k @ 4.3ghz
ASUS Rampage IV Extreme
2 x GTX 690 in Quad SLI
H100 CPU Cooler
16Gb G.Skill 2133Mhz RAM
I am using EVGA Precision X 3.04 & Unigine Heaven 3.0 (1920x1080, all settings maxed)
PT 135%
GPU +120
MEM +100
On one card the benchmark finishes but when I put the other card in it lasts about 40 seconds and the system hangs.
At stock speeds both cards work fine. Any ideas on why these same cards behave differently?
