Hello... you will only be able to use the DDR3 ram in your new MB... the DDR2 ram has different slot keys and will not physically fit... you can use 1333 DDR3 ram too if a better price option is available... 2gb DDR2 sticks can be sold on EBAY yet, at a good price.
Thanx Ironsounds. Had no idea of pin configuration. I checked 1333MHz prices, and they're more expensive!?! Posts I've read say 1600 is better so I will go for the original recommendation. May just have to wait a while longer. Thanx also for the e-bay tip, will check it out.
