Can i just swap...................

[hse180]

I currently have 2x512 geil1 ram running at ddr500 and have just purchased 2x1g mushkin XP4000 redline.
The question i have is that my system is overclocked some (not by me) ,and was wondering if i can just swap them over?
But the problem i see is that the Geil is running at 3.2v and the Mushkin runs at 2.8
Is there something i must do so i dont damage the Muskin.

Before you change anything, go into the bios and change the voltage to 2.8 and the timings to whatever they are for the new ram.

Save and then power down.

Remove old ram.

Fit new ram.

would this affect the o/c on the cpu?
I am a newb to o/c and read the guides many times for information, just in case i would have to reset all the clocks.

Well, it runs at the same speed, so shouldnt be a problem.
