Elminster, that's the setup I have except XMS2700 memory. With a SLX63X packed 9/14/02, retails hs, fan & even thermal tape it was an easy overclock. I have a pci ATA/100 card that caused some instability until I upped the vcore. All other settings are at default, so the lan & sound are enabled and memory voltage is normal. Also running w/ 4 hard drives, 2 CD-RW drives, a DVD drive, a winmodem pci card, and soundblaster live pci card.
Underclocking the memory allowed me to increase the fsb a bit. I'd bet that if I had higher speed rated DDR, put AS on and took out everything except my primary hard drive and my video card I could hit 155fsb for a 2.8GHz system. I'm fine at my current speed, but at some point curiosity will over come me & I'll uninstall all of the non-essential stuff to see if I can hit it
