I inherited an ASUS P4C800-E Deluxe with Bios 1023 and 2 gigs of pc3200 ram. 32 bit Win 7 is running and I want to max the board (4 gigs). I know the operating system won't allow for the full use of 4 gigs of ram. Has anyone experienced any issues with maxing this board out?
Your ram fsb could drop from 400 to 333 with all 4 ram slots filled, but you won't notice the difference. I recommend you leave your system alone; 2 gigs of ram is plenty for 32 bit windows versions. I use windows 7 ultimate 32 bit, and it runs fine with 2 gigs.
