Same EVGA card and I've set mine almost exactly the same except the following.
Used Afterburner and enabled the basic over-volting option. Set that to +27mV as more doesn't seem to allow more OC just a bit more stability. Set the turbo to 1450 MHz just like you but I am running the memory at +450 MHz
I'd rather stay at that level and keep in the 40s DegC rather than try to push it for a few more percent gain in fps.
Thanks. Ill try that tomorrow. Precision seems to be a bit buggy with loading on windows start and applying OC settings. Ill try afterburner.
