Ok, it most likely isn't stable...I admit it. So I originally shot for a 4.3 OC with my newly purchased 212 EVO, and upped the voltage slowly all the way to 1.38 while testing with Prime95. I kept getting the error "rounding was 0.5 expected less than 0.4" and one or two of the cores would drop from 100% to 0-15% usage...and my PC would lock up about half the time I ran the test (blend). I kept the voltage the same and went down to 4.2Ghz, and then 4.1Ghz, and I still keep getting the same error and core 6 will drop down to 0-15% usage, now with no freezing. The thing is, I'm able to play games and run all my normal tasks just fine. When I search for what others have their settings at to OC this CPU, none of them seem to need to go all the way to 1.38 volts for even a 4.2Ghz overclock. What do you guys think could be the issue?
P.S. I have also tested the RAM with Memtest several times and it has tested clean...BUT ever since I purchased the RAM (8gb DDR3 1600Mhz Ballistix Sport dual-channel) about 7 months ago I have not been able to get it to function in dual-channel mode. The motherboard only seems to detect the full 8gbs if I use the single channel slots. So I guess there could be some issue with either the mobo or RAM.
