Need to up RAM volts on my PERL

Hey guys, just got a new D865PERL, and 2 512 GIEL sticks... They're currentley running on 2-3-3-6 but I was trying to get them to 2-2-2-5. It wouldn't work, So I thought it would If I up the voltages. Tried doing it through the mobo but I couldn't find a way to...

Any suggestion anyone?

The PERL mobo is not an ocing mobo. Doesn't have ocing features in the bios. No way of adjusting anything anyways. This mobo is just meant to run stock period. If you wanted to oc, you got the wrong mobo for that.

Sry charlie-

Nah I didn't get this mobo for OC'ing I would have gotten an IC7, I got this mobo for a good price, and thought what have I got to loose, it's good enough.
