RAM question

[michaelcooper5]

As posted on my system spec's, I have 2 x 2mb sticks of OCZ Reaper 8500 ram. On the DFI motherboard i have, as we all know, four RAM slots .. What would be the benefit and would you suggest I fill the other two slot up with 2 more sticks of the Reaper RAM?
Would i see a performance increase? Thanks for my RAM schooling, much appreciated!

You should see some nice improvements in speed in Vista and stuff like photo editing. For the price of memory at the moment, I don't think you can ever really have too much
