Okay thanks Don ;p

Bottom line on 3rd gig of ram: 3.2 recognized(despite 4 being installed hardware-wise) is more or less equal to simply 3gb; though if you 5box, it might make a noticeable difference. The 2 dual-channel sticks, if placed in the correct slots, will still work as dual-channel, then adding a third will simply make that single, third stick non-dual

I have 2gb ddr2 dualchannel setup as the H's in your diagram so yeah I'm good then ;p I might grab a third stick just for the performance increase soonish, though at this rate I may just sit down one weekend and do a complete overhaul of my case and specs; I've got a perfectly good, probably-faster(than my current IDE HD) SATA drive sittin around brand new unused, my case is getting crowded(and probably a bit dusty) and not to mention is an ugly 7+ year old beige case I've simply upgraded parts "into" over the years, I think it's about time to get a fancy tower case with more room for my drives and without the poor processor being stuck under the power supply lol in addition to the extra RAM and HD
