Check RAM voltage?

[emacsomancer]

Is there any way to check the RAM voltage on a x220? (I'm running Linux on it, if that makes any difference.)

I couldn't find anything in the bios, and I tried various Linux tools which spit out RAM info, but nothing tells me what voltage the RAM chips are running at.

(I'm curious because I put 1.35 low voltage memory in, and I wondered if it's actually running at 1.35 or really at 1.5.)

[edit: I put "battery" rather than "RAM" in the original post title.]

download cpu-z, run the program and you would be able to see the operational voltage under memory section.
