Suggestions about more RAM for my mobo

I'm currently considering throwing more RAM into my current system. My mobo is an Asus K8N:

I already have 2x 512MB DDR400 Corsair RAM running in it. The CAS latency on the RAM is 2.5. Basically, the following RAM is the exact same as the two I currently have:

Would getting that 3rd chip inhibit performance since my mobo says it dual channels my RAM?

slapping a 3rd still will remove dual channel, and you will lose a chuck of speed.

ktr is spot on. you'll loose dual channel, which will seriously decrease speed. now, if you upgrade in identical matched pairs, you should be able to retain the dual channel. you have to weigh ram capacity versus speed (capacity if you do a lot of multitasking, etc, speed if you play games and do other intense tasks like that)

Thanks guys. Guess I'll just save the money for the next system.
