I fully realize that this question has probably been answered before, however I have been unable to find the pertinent posts/answers.

I was running 4 (2 x 2 DDR2)gigs of ram and recently had a stick of ram die on me and so purchased 2 new sticks (same timing and speed, different manufacturer). My question is will I gain any increase in performance in running 6 (2 x 3 with 1 unpaired stick) vs 4 (2 x 2) gigs of ram.

Mobo: MSI P45 Platinum
CPU: E8400

Thanks very much in advance

Depends on your setup; are you using a triple-channel platform like X58 (core i7 920) or a dual-channel one like the P55 (core i5 750)?

If you are running a 32-bit OS, there will be no increase because 32-bit OSes can only see and use about 3.5GBs of total memory. If you are running a 64-bit system, maybe, you will lose the dual channel - check you motherboard manual for the MSI's recommended RAM configuration.

I am running a 64 bit OS and it is a dual channel system, which is why I was wondering about the loss of the dual channel vs extra memory. I will double check the manual, didn't see anything on first glance but very well may have missed something.

TYVM for replies!
