my memory has been underclocked to match the cpu frequency and they are now running at 1:1 ratio according to CPU-Z, i want to reatin my Dual Channel memory (interleaved) so i have decided to get another gig (2 x 512) so after adding this i should have 3gig memory al together.

Do you see any reason why i shouldnt get the additional 1 gig (2x512)? it just seems that the timings are way different would this cause me a problem?

can you make any recomendations from the crucial site?

Thanks,

 

With 2GB already installed,you have enough to run just about any program
out there,unless you are doing some serious professional video creation or something.
You can run that extra memory,but will have to downclock the slower speed.
You might want to check newegg.com for deals as DDR2 memory has been going
pretty cheap lately.
There is no reason you can't run the memory speed that the board is rated for
as CPU and memory bus speeds are controlled independently.
You shouldn't have to sacifice performance and run 1:1.
