Hi. I've just built my first rig for years, and I'm attempting to OC it - something I haven't done in the past.
I'm not really sure what I'm doing, but I've been trying to get to grips with it over the past few days.
But, have been unable to get even a moderate OC stable, and seemed to be having lots of problems with my
RAM. Orthos would be fine with
CPU tests, but gave me hassle whenever I introduced the blend test.
So, I changed my
ram from Corsair XMS2 6400, to OCZ Reaper 1066, and Initially have had MUCH better results.
My set-up:
E8400 with AC Freezer Pro 7
ABit IX38 QuadGT
4870s Crossfired
4GB OCZ Reaper 1066
Lian Li B25B case
Corsair TX750

This gives me a fairly stable system, and runs Orthos in blend mode for 35 minutes before getting an error.
But, 3D mark crashes upon completion, Crysis Bench crashes during, and UGuru freezes the system on launch.
Could anyone point out where I'm going wrong please?
