I have a Asus P4T533-c motherboard. I currently have 512 of RDRAM. I have been searching for more RAM to bring it up to at least 1gig. However RDRAM is so expensive I am wondering if it wouldn't be more cost effective to change out my board and go with a different type of RAM? I got this board as a package with a P4 2.6 chip and the RAM. I don't even know what speed the RAM is. Thank you in advance for any advice you may have.
