I popped an XP1600+ into an e-machines a long while back, and I find out today it's been running overclocked the whole time. Anyways, was having some stability issues, memtest86 gave errors like crazy.

I'm trying to find how to set the fsb, and there's just one jumber that switches between 100MHz & 166MHz. So underclocked, the cpu & memory seem to run fine, memtest86 doesn't show any errors.

So now I'd like to set it the fsb at 133MHz, but I do not know how, or it I even can? The board is supposed to be able to, according to google searches.
