RAM Voltage Question...

[jjblanche]

For my particular RAM (G.Skill 1000 2x2), the "test voltage" is 2.0-2.1v. I was actually having a stability problem, because BIOS was defaulting the voltage to 1.88v. So, I upped it to 2.06v. Booted fine. Ran large FFTs for ten minutes before a reboot. Now, that could have been due to my processor's voltage, as that's what I'm pushing at the moment, but nevertheless, to be sure, I increased the voltage on both the CPU and the RAM. The RAM is now at 2.116 according to BIOS, which is just a shade beyond the "test voltage." I'm wondering if this would cause any problems.

I think 2.2v is on the upper-limit of most RAM, so you should be alright. It might just cost a little bit more on the power bill. Just keep a careful eye on it for a week or two to make sure nothing goes wrong. Better safe than sorry!

cpu z can read ram spec, check them

2.0-2.1v...I already know that much. At 2.06 it may or may not have been stable. I know at 2.116 it is, but I just wanted to verify that the extra .016 voltage isn't going to harm anything.

JJ- if you want to test the RAM, underclock the CPU with a multiplier and OC the RAM. You can NOT test both at the same time and upping voltage to both was not a good idea.

Normally I will go up to 2.35v for 24/7 on RAM (it's really cheap now so I don't care if I burn it out). If you are worried about burning it than 2.2v is the way to go.

I'll go up to 2.5-2.6v for Benchmarks.

Sometimes too much voltage will cause instabilities. If it only requires 1.8v and you set it to 2.2v, expect tons of BSOD.

It requires 2.0-2.1v. I was getting tons of errors with 1.8v, that was my original problem. I have it set now to 2.116v, and my question is, will the extra .016v cause a problem? I think no, because it's such a small increase over the test voltage, but I figured I'd ask to be sure. I'm not running it at anywhere near 2.2v.
