Amount of ram and folding speed

I was just wondering if the amount of ram makes a difference to how fast the PC folds? Because Im getting a new setup with DDR and I was thinking of selling my 512mb stick and putting 64mb in this and having it fold.

No it doesnt make a great deal of difference, the main things that affect folding are CPU speed, FSB and memory timings. The most important one being clock speed, 64MB should be fine for a dedicated folder although the OS may be a touch slow but that doesnt really matter, a great deal
