It will definitely work at CAS 2 (see page 23 in the manual) but only at 266Mhz. If you want to run CAS2 at 333Mhz you will be technically overclocking. It may work, and then again it may not. But you can still try. Worst case scenario is you'll be underclocking your RAM. No big deal.

This board was designed for pc2100 cas 2-2.5 memory. I would recommend exchanging it for some. Go to the AMD website and do a search on recommended memory. Micron, Samsung, and Hynix are all good choices. You will get no performance gain by using what you have but you are definately not using recommended memory and are underusing what you have. Problems (error messages)may develop by not using what the board is designed to use even though there may be no hardware damage.
"Underusing"? That's not even a word. It doesn't matter if you use faster memory, you can keep higher speeds, it will just drop down to match the FSB, unless you force it to not be sychronous in the BIOS.
Thanks for the info guys, I baught the higher memory because i see no point in spending the money on old memory i cant use if i decide that this Nforce chipset is not for me.. so i got faster ram incase i decide to buy a new board, your info was helpful.. i wasnt 100% sure if it was the same idea as it used to be with sd.. because i COULD use pc133 with pc100 boards
No problems using faster memory at slower speeds... really means its running underclocked so you can use really aggressive memory timings with no issues.
