How do you buy "non-dual channel" ram?
Dual Channel is a Motherboard function. I can take old DDR2100 RAM made before Dual Channel was available and run it in Dual Channel as long as the motherboard supports it...
Are you saying that you have 2 unmatched 512Mb sticks? In theory it's possible to get non-matched sticks to DC as long as they're the same size, but there's a large risk of instability and most boards won't even try it.
If you're looking to buy an additional 1gb of RAM, try to match the sticks you already have. General rule of thumb for any RAM upgrades, Dual Channel setup or not.
yea I was thinking of getting another gig of ram but the ram I have now I can't seem to get anymore I tried a gig of corsair but my system wouldnt even recognize it.
