Is my overclock Unstable or should I get a bigger power supply?


I currently have an antec ea 750w 80 plus

However I am a little skeptical about it

As I am currently running a 2600k @ 5.0 ghz with 1.456 voltage

Corsair Vengeance DDR3 1600 mhz
Timings : 9-9-9-21-1 Voltage : 1.515v

MSI GTX 660 Ti Power Edition

Default Core : 1020 Memory Memory 1502 boost 1098

Current with Power at 114% no tweaking done to voltage core using MSI after burner

Default : 1082
Memory: 1700
boost: 1160

overclocked and boost in all categories that might use the 12 v rail

I also running 1 hybrid hard drive which should not matter much.

However my system just sometimes dies on me randomly and I get blue screen fragmentation which memory needs to be cleared. Is this indication I need more voltage to my overclock because it's not stable or do I need to buy a new power supply unit because I don't have enough voltage?

Thanks reply soon,

  2. Try lowering your CPU overclock a bit, if the crashes stop, then you know that was the issue.

    Also I wouldnt run the CPU at that frequency on a daily basis, was just on a thread where someone was running their 2500k at 5Ghz and it burnt out and cant get above 4.7Ghz.
