Need Help w/Memory Voltage

My computer has been on the fritz lately. I am running a utility called Core Center which came with my MSI mobo and have been getting warnings for the past couple weeks when my memory voltage has been dropping below a certain point. It fluctuates anywhere b/w 2.5 - 3.2 and has been crashing my computer lately when running too low for long periods of time. Any idea what might be causing the problem? My CPU is not overclocked. Time for new RAM? Power Supply?

playing games, running videos seems to make this occur more frequently.

the voltage shouldn't vary that much. 3.2v is pretty high and unless you're using BH-5 or UTT, you shouldn't even come near that.

please list your complete system spec's.
also, any software or stress testing that you may have already done as well.
