Thanks guys I really appreciate it. temps seem pretty good, nothing to worry about 64 at max but that wasn't at max performance.
Using HWMonitor My GTX 1070Ti had Voltage at Value:1.044 Min:0.850 Max:1.050
that was in the Alabao R66 Orbx Cairns, Oculus Rift,, 30 seconds after those values, BOOM! pc restart as I headed to the city of cairns.
I have all the p3d values dummed down, all drivers up to date.
ram test. ok
I actually had a R9 390x which did the same thing, so thinking it was the problem I bought this 1070Ti only to have the same issue.
