Default voltage

[SkinnyBones]

Whats the default voltage that my memory should be running at? Mine says 2.65v. And if this isn't default i was wondering if this could be making my games crash.

what kinda ram do you have? most likely 2.7 is default........look up your ram on Newegg, it will tell you, or the products site

A lot of ram states the working voltage on the sticker, mine for instance says 2.8v on it. In most bios's you'll have the option for either 2.5v, 2.6v, 2.7v & 2.8v (and some go beyond this) or like mine Default (2.5v) +.10, +.20, +.30, etc.

According to JEDEC specs the working voltage for DDR is 2.5v but many manufacturers go above that voltage for added stability at higher speed (mines PC4200) or lower cas latencies or both.

If you'll look in the PC Health tab for your bios it'll tell you the voltage that your dimm is receiving (most modern bios's will at any rate) and if it's below what your ram requires you can adjust the VDIMM in the bios to get the voltage where it needs to be.

ddr400 is actually 2.6v

and from your post i take it you have stability problems? try bumping voltage up to 2.7 or 2.75v

I got this from Kingston's site:

Memtest, Prime, drivers especially video, virus/spyware scan, make sure all software involved especially the OS & the game itself are legal copies...

What are the timings you're running the ram at? Is it value ram or XMS?

kingston is wrong, sorry.
