Question Can I install DDR2 RAM's of different frequency?

[Pradeep17]

I have dynet DDR2 334.2Mhz 1GB RAM installed in one slot, when I search for the same RAM I am not finding it anywhere so can I install "HYNIX 1GB DDR2 RAM 667FSB DDR2-5300U-555-12 Desktop RAM "?
(PS: Both RAM slots colors are Blue).

THANK YOU!

Mixing makes/models of memory can produce undesirable results, especially with older memory. You really won't know if they will play well together until you try it.

What if I replace older one with newer ones?

same rule applies. mixing ram (ram that is not sold together as a kit) is not guaranteed to work. it might, but sometimes you have issues from not working to working at lower specs. if you get a kit of two to replace them, that will work if that ram is compatible with your mobo.
