Disable the XMP, and run at Stock for a little while and see if this improves.

Ill try that, but the stock values specified by corsair seem to match what XMP set the values at, but I will try that, and report back with my findings later, thank you!

Somethings just struck me, would memtest86 pick up on an error if the XMP is the issue or not? Or could there be a chance of false positives or negatives etc, with incorrectly configured ram? Because I'm running memtest right now but I havent disabled XMP yet and I'm unsure of how it may affect the test, if it would at all.

im not to sure on that one, Try to run it at stock then with it on. What profile are you using with XMP?

My BIOS only has an option to enable or disable XMP, theres no sort of profile selection, but, incase ive misunderstood, my ram is configured thus; 9-9-9-24 timings, 1600MHz and 1.5V If that is helpful in anyway haha

Well, as it turns out, I disabled XMP and my memory returned to its stock clock of 1333MHz (Despite the manufacturer saying that the ram was rated for 1600MHz) and, I decided as I was restarting anyway, it was worth a punt at trying Prime95 again before I ran a new memtest, I've been running a blend test for 10 minutes now, and normally it would have frozen the system within seconds, now I'm not saying its fixed, I know this is very much one of those things that you can't know if its fixed straight away, you have to play the waiting game and see it if the problem rears its head again, but right now I'm hopeful. Assuming that the XMP is the problem, I'm assuming its something to do with undervoltage for the higher clock rate, what would be your opinion?

I'll run another memtest but honestly I believe the problem to be fixed, only question now is how to get my system stable with the RAM running at 1600MHz, like Corsair claim it should be.

Well thats rather worrying, only thing is, I'm unsure how to isolate which stick it is that can't handle running at that clock, because sometimes a freeze wont happen for days and memtest isnt picking anything up... It could take me weeks to find the faulty stick haha!
