Title: Quick RAM question
Post by: jacktheripper305 on March 12, 2009, 09:54:13 PM: I'm looking to add some RAM to my computer, as a cheap, easy upgrade.

Currently I have 2x 1 GB DDR2, and I'm not sure what the frequency is. Hence my question:

If I put 2 more 1 GB chips on the secondary channel, does the frequency matter? or does it have to be the same as the current modules?

If the frequencies don't match they modules will run at the lowest frequency of any of the modules.

Your mobo specs..
