RAM voltage seems low, could you post a link of your RAM?

Edit: I just looked at some Mushkin RAM and it seems that their voltage isn't as high as I thought.

Check your Power Supply. They can cause all kinds of random weird issues.
If you have a spare, hook it up and see if it solves the problem.
