my maximum vcore adjustment is up to 1.6v...
how fast can i push my xp1800+ thoroughbred with that voltage?

Jenz,
Your title block says you have a K6-2 350, but as to your question about the XP 1800. I run the XP 1800 Thuroughbred A on a MSI KT4 Ultra, which only allows me to set my vcore up to 1.6. I run my CPU 100% stable at 145 x 12, 1.6 vcore. I had it up to 145 x 12.5, 1.6 vocre, and at 150 x 12, 1.6 vcore but I was running in to stability probs with those last two settings. I believe this is because my Vid Card, and PCI cards could not handle the higher FSB. The Bus speed for the AGP, and PCI are usually derived from the FSB 1/2 for AGP, 1/4 for PCI, so as you up the FSB they up as well. You may not have problems with the higher settings I tried if your mobo lets you control the bus speed for AGP and PCI slots (some do). I read on a site somewhere of a guy who had his 1800 at 1.91G. Hope this helps.

I can get my xp1700 up 2 1736 using 11/158 but i only got that when i put my pc2700LL ram in before i got about 1620 stable. Think better ram helps
