What is the CAS latency on the memory you bought? That's the only
thing I can think of that may cause an issue of not even POSTing
besides two bad sticks of RAM. When I'm not 100% sure what kind of
memory to get for a computer, I always go to to both look
up what's needed and most likely purchase it. Their prices aren't bad
and they guarantee the memory to work with the model you bought it for

Looks like this requires a CAS of 2.5.
