I have had this processor and a Asus P8/67 motehr board for about two years. I have run it at stock voltage at 4200 ghz with no issues on a shitty air cooler the whole time with temps around 42c average. I recently bought a new case and a Corsair H101 water cooler. At same setting the cpu temp is now about 30c average at load. I wanted to see what the processor could do so increased the multiplier to 45 and ran prime for about 4 hours stable at 1.305 volts stable. Temp never went above 35c. Now my system will not even boot into windows without locking up. If I lower back to multiplier of 42 it does fine. I have looke at all the SB overclocking guides and followed them religiously. IF I change bios to 4500ghz and reset with out shutting down it will boot into windows. It only locks up if doing a cold start up. Anyone have any ideas what is going on???
