You'll need to verify the regulator chip is capable of CUMine voltage, 1.7vdc. Find the regulator chip (close to the slot 1). Look at the manufacture numbering on its surface. If the numbering ends in BCB, the motherboard regulator can cope.

Have the ASUS MB P2B-b and am having same dilemma. Manual only list CPU's up to 450 pII and Celery 366, Extra leaflet upgraded the manual to PIII 600 using 6 muliplier times 100mz,and Celery 500 using 7.5 miltiplier times 66mz. Local computer shop web site lists 750 PIII at 100 mz for sale. Don't see why 750 wouldn't workd unless they changed voltage. Checked Asus site, and doesn't list upgraded leaflet. Don't think that an 850 will work.
