Thanks for the reply, Ken.
The motherboard that you have linked to is the same as the one that I am using and I have 64-bit Vista so no issues there.
Two more questions, if you don't mind...
1. Is it o.k. to mix different manufacturers of memory stick? eg. could I pop a couple of Corsair sticks in along side the Geil ones, or should I use the same brand/model?
2. Should I keep the specs the same or are there any advantages to changing some of the 'numbers'? The cards I have are 1 Gb PC2-6400, DDR2-800, CL=4-4-4-12, 2.0v
Even though I have assembled this p.c. from scratch I know very little about such things, the last computer I had before this was a Commodore 64, so I appreciate the help given...
Cheers,
Rich.
