Funked,
Should work fine. PC2700 is just a rating for the RAM's max guaranteed bus speed. It will run at the speed set in the BIOS (default 266 for and Nforce1 unless you overclock the CPU). I still have an Asus A7N266-c in my Gum rig. I think its latest BIOS supported the 2600+ w 266(133) FSB and PC2100. The rig in my sig has PC3500 installed in an Nfornce2 board supporting 400 FSB and PC3200.
