Also, if I am going to go from 2 gigs ram (2 of 4 slots filled) to 3 gigs, do I have to fill the other two slots with 512's or can I just but a 1 gig stick in the third slot and leave the 4th slot open?
The ram is DDR 400.
Thanks again.
As far as I'm aware it will depend on the sophistication of your motherboard - it is technically possible for a single DDR to be accessed and used. However, if you have an odd number of DDR's the performance of the memory will be affected. The gains DDR memory makes are based on pairs of devices.
