800mhz in a 667mhz mobo

post #1 of 4
Thread Starter 
Say there's a system with 800mhz DDR2 RAM installed in a mobo that specifies only 667mhz, 533, or 400... what would be the ill effects?

The voltage is 1.8 on both.

As long as the RAM can operate at the voltage that the mobo can supply, it doesn't matter what the rated speed of the RAM is. However, some 800MHz modules require 2.1 volts stock--this may be why. Just match the spec's of the RAM vs. the motherboard as far as VDIMM goes--the RAM will be clocked at stock regardless of what it is capable of running at.

It will just underclock itself to the specific mhz, don't worry about it
