FSB support question?

I have a gigabyte GA-7VRXP socket A motherboard that I bought when an athlon XP 2600+ was the greatest thing going. It says it only supports a fsb of 266 but is that just because nothing higher was available? I tried to up the FSB a little but the PC-2100 ram is a definate limiting factor. Is the motherboard also limiting my performance?
 
That board uses the KT333 chipset, which IIRC does support a FSB of 333. I'd bet that it's your RAM.

Would upping the voltage on the ram help that?

yes, upping the voltage can help, though only to so much. bump the voltage up to 2.7-2.8 and see how high you can get.

Many KT333 boards supported DDR333 but not FSB333 until much later. I don't think it was the chipset, per se, VIA wouldn't give its 'official' blessing to FSB333 on the KT333 until later revisions, so vendors didn't put too much effort into designing a KT333 board that would go much beyond the 'official' FSB266.

GA-7VRXP R3.0 does support 333MHz FSB, but a quick check of Gigabyte newsgroups doesn't show many success stories (none that I could find) getting any previous revisions to run @ 333MHz.
