PC only stable with OC, not at stock?

Hello,

My PC has been crashing mid-game on a new MOBA. Its fairly random and happens once a day.

I figured I'd stick at stock for awhile just for the stability. The system is a 2500k with 8Gb of RAM on a P8Z68-V.

When running at stock, games will not load. Games that get close to loading, I get a BSOD. Letting the BIOS do its own OC'ing, the PC is stable again. I originally thought this was the RAM (and still might be, since all issues point to it, memtest giving lots of errors), but I have a problem getting it stable even with a modest overclock and a good amount of headroom for voltage.

Its very late here so can dig in for more details, but is having an OC with more CPU/DRAM voltage over stock for stability point to a obvious issue? Might it be the power-supply?

I've had this PC for 6 years running at 4.5Ghz, with the only change of hardware being HD's and graphics card. I'm waiting until Zen to build my next PC, but I dont want this one to die in the meantime.

Kai.

Its running the XMP profile. The OC is currently at 3.7Ghz, I've set voltage on CPU to 1.28v and RAM to 1.6v (will clarify that actually, but its just below the text turns yellow, as an indicator of a highish metric).

The power supply is a Seasonic M12 500W.

Again all these components had been running a modest increase in voltage and at 4.5Ghz for years. I've no problem living with this at stock but thats apart of the problem.

Prime95 blend test for 30 minutes gave me passes. Heat test puts CPU to around 55degrees. The game still dies on me though (better than a BSOD).

Im going to try removing a stick of RAM and see if one is faulty. Can I keep the OC profile while doing this? I know it should ideally be at stock but it might not matter.

Kai.
