Well my MOBO(http://www.tigerdirect.ca/applicatio...?EdpNo=1194276
) has 2 slots for DDR and 2 for DDR2, for my 2 DDR slots I have 512x2 of Corsair value select. now i'm thinking to buy some DDR2 ram for my other slots.
I was looking at Corsair Value Select Dual Channel 1024MB PC4200 DDR2 Memory (2 x 512MB)(http://www.tigerdirect.ca/applicatio...?EdpNo=1168922
) because they match my other RAM but they are DDR2.
Then i was looking at Corsair TWINX 1024MB PC5400 667MHz Dual Channel DDR2 Memory (2 x 512MB)( http://www.tigerdirect.ca/applicatio...?EdpNo=1010860
. they are better and are still made by Corsair so i was thinking they should be OK and won't cause crap with my other RAM. I'm willing to put out the extra money for them so that doesn't really matter.
