Ok so volts cause heat and seeing as I don't want or need to push my memory and don't want loads of bsod what's a sensible minimum I can expect 2 x 4gb sticks of corsair vengeance 2400mhz to happily run at?
My mobo sets it at 1.65v so I have currently backed it off to 1.6v and all seems well.
Asus Ranger VII
Pentium K 3258 at 4Ghz 1.18vcore

Cheers.
 
Depends if you are willing to drop clock speeds.

2400 will be an XMP setting and will be rated to 1.65v or 1.6v.

If you go to 1600 you'd get away with the stock DDR3 voltage of 1.5v. Going lower might be less easy.
 
Your RAM makes almost no heat so there is almost nothing to save. If you want to do it, then under volt the ram bit by bit until you get errors.

Unstable RAM sucks though and can ruin a windows install.
 
Of course you can under-volt ram.

I have

1333 at 1.3v
1600 at 1.4v
1600 (samsung green) at 1.2v
some early old 1600 Corsair Memory at 1.4v also

Some of those machines are running neural networks 24/5, totally totally stable.

PS Does help if you have a very stable PSU. I'm running Seasonic X series on most of those.
