My System Specs

Does this mean I'm not giving enough voltage to my cpu, or my multiplier is too high? On my previous test, my voltage was at 1.100, my multiplier was at 41 and I received that error. I decided to increase my voltage to 1.105 and leave my multiplier at 41, which still produced that error. Am I doing something incorrect? The CPU is the only component I have overclocked on my system.

ASRock Z77 Extreme4
CM Hyper Evo 212
Patriot Viper 4x4GB

Currently running at:
Voltage: 1.105
Multiplier: 41
Yes...... ;)

It could be any number of things whether it's voltages, or a multi/frequency that's beyond what your current setup will allow (mem/cpu/motherboard/chipset/etc.....) , but basically it's telling you that the OC isn't stable.

Are you taking the OC up slowly or did you pick a goal and attempt to set it? I normally pick a mid level OC that I know should be easy to attain and then once I assure myself that it's stable at that level I start bumping up slowly.
