1.8v RAM on a 1.5v mobo? (MSI p45-C51, Corsair TW3X4G1600C9D)


I'm a noob so if someone could also provide a bit of an explanation as to how RAM voltages work, that would be great.

I have a P45-C51 mobo and recently bought the Corsair XMS3. To cut a long story short, XMS3 was faulty and replaced with the Dominator. The dominator however is 1.8v and my mobo is only 1.5v? My questions are:

Will the RAM work in the mobo?

Everything will be running at default. Wont be overclocking any time soon/ever. I'm also not overly concerned if the RAM runs at a lower speed, as there is very little chance I would notice it. My PC has been out of action for a month and I'm started to get the shakes. Any help will be much appreciated. Thanks.

  1. memory quality may be defined by it's ability to run at stock voltage settings vs it's highest clock rating.
    Example chip a: 1333mhz 9-9-9-24 at 1.5v
    Example chip b: 1333mhz 9-9-9-24 at 1.65v
    chip a is of superior quality.
    Later models of intel processors with internal memory controllers don't want memory voltages to exceed 1.65v warranty issue.
