I recently upgraded one of my computers and have an extra stick of ram. I was wondering, will it benefit me, or decrease my pc speed installing it my other computer, here's the specs:
Extra stick of ram is 512mb ddr2 533mhz
I currently have 2x2gb ddr2 800mhz running dual channel, installed in slots 1 and 3
I want to install the extra chip in slot 2. I know the ram is compatible with the system, my only concern is that it is a different speed that the other ram. The extra chip will be running on a different channel, but i didn't know if the bios would underclock all the ram to make it compatible with the 533 or would it leave it alone because it's on a different channel.

The extra memory module you have is rated lower then what you currently have in your machine. Typically, RAM modules will function at the speed of your lowest rated stick.. So if you have 2x 800 Mhz stick and add the 533Mhz stick. Allthough your system memory will increase; your bandwidth will in fact decrease.. In some applications, the difference will be negligeable to you. I would test it and try.. If you play games or run intensive applications, you may see a slight performance reduction. Also in some cases, the memory module will not even work with the two other modules..

Another thing to keep in mind is what do you do with your pc and do you often do you even use all 4gb of ram?
You can view your ram usage via task manager/performance.
If the hardest that you work your pc is with video games, then 4gb is plenty. if you do a lot of video editing (not copying of dvd's) or large Photoshop projects, then more ram will help.
So if you don't use what ram you have, then as stated above, the extra stick will most likely hurt your performance.
