mixing memory

[bucfanmike]

i have 2x512 ddr400 using a gigabyte k8ns ultra 939 mb.

a friend has 2x512 dr533. is it ok to add these, i believe from what i read along time ago, all the memory will work, just at the speed of the lowest pair.

thanks

It will work, although you'll have to run all 4 sticks @ ~200 Mhz, and at the timings of the slowest pair. You'd probably be better of just selling the PC3200, and trying to buy another 2x512 MB of PC4200, if you're an overclocker.

edit: Note that whether it will even be able to run @ 200 Mhz depends completely on your processor, not on your motherboard.

ok..not an overclocker, run an amd 3000. i dont do anything cpu or ram intensive, just want to be at 2 gig for vista install. SHould i just stick with my original plan to add 2x512 pc3200 to match my current two sticks?
