Corsair Vengeance memory voltages.

I've had my new build running for around a month now, and I havent really got round to overclocking anything yet, and to be honest not bothered overclocking anything for a while.

However, I have 8gig (2x4gig) of this memory (in the black casing) in my system and it has an XMP profile that means it can run at 1866.

Long story short, it wont.
I have it all set correctly in the Bios, it will boot up and run in windows, and run games and do stress tests, it wont however go into sleep, and when you reboot it it says failed overclock on the Bios screen.

I've been reading around and the consensus is more volts.

Standard is 1.5 even on the XMP profile, shall I just bang 1.6v through it and see if it sorts it then wind it back bit by bit?
Correct?

If you're sure the RAM is the problem I'd start at something like 1.55V and work your way up or down from there.

If you have Sandy Bridge you ideally want to use a maximum of 1.58V and the closer to 1.5V the better.

Well, 1.6v solved the sleeping problem, So i'll try knocking it back a bit at a time till it stops working.
Why does having having a sandybridge chipset mean I shouldnt use 1.6v though?

The memory controller is on the processor and Intel recommend 1.5V +/- 5%.

To much voltage can potentially cause damage to the processor.

The nearer to 1.5V you can get the better.
