Hi, I'm running a P4 1.7 with and Asus P4S-333. I currently have 256 MB of Samsung PC-2700 ram and want to add some more. There are excellent prices around for 512MB modules but they are PC-3200. I'm curious as to whether or not this is going to cause me any problems because if that's the case, I'd rather just pay the extra. Thanks for the help.
