<< What are you gonna overclock?? Not many boards will allow you to adjust the speed of the RAM as it runs synchronously with the FSB. That is if you're overclockign via FSB. If you're doing so, get two sticks of high quality RAM as you need it.
If you're overclocking via multiplier, go ahead and buy a stick of 512. 🙂 >>
P4 1.6A GHz with Gigabyte 8SRX. It has good overclocking potential, a lot of options with FSB and voltage. I did decide to go with the stick of 512mb. When I save some more money, I was 1 GB of memory.... =)
Just hope this will overclock well....
