Your ram has spd settings you can check in cpu-z, and these settings have various speeds, timings and voltatges. Find out the speed at which your ram can run at around 1.8v, and manually enter it into the bios, and set your vtt to at least 1.35v, and you'll be fine.
He's exactly right.

What you need to do is to clock down your ram so that you can feed it less volts (undervolt).

I would pick a low ram divider = DDR3 1066 (if available should be the sweet spot)

Give it the lowest volts it needs to run stable (Maybe 1.65, at most at default CAS latency and timings)

Remember, you want to maintain a .5v difference between vdimm and vtt, so 1.65v means you could run vtt as low as 1.15v.

To be safe, I'd set 1.3v vtt (this will allow you to overclock past 4Ghz), allowing you to push vdimm all the way to 1.75v (a .45 difference, which also makes room for overvolting on your mobo).

Be sure to set everything manually! Trust nothing to AUTO. Goodluck.
