Power Down Enable - what does it do

[dazed_00]

In my BIOS settings for RAM, there is a setting for 'Power Down Enable' which is disabled by default.

I'd like to ask what does this do? Is there a significant performance difference if I enable it?

My motherboard is MSI 760GM-P33 . AMD 760G and SB710 Chipset. RAM is 2 x 2GB DDR3 Kingstom RAM.

Power Down Enable is a power saving feature that powers doen the ram slots to a lower voltage when the computer is not in use. It causes lots of compatibility problems, that's why it is disabled by default. It has no effect on performance. You should leave it disabled.
