at last i found a way to increase fix vcore on socket370 mobo...like my DFI CA61...
previously i fail to oc my cII to 850mhz on the board as the vcore is auto detected at 1.50v...
after have some look at the celeron datasheet...i found that there is way to manually change the voltage identification (VID) by modifying the VID0 VID1 VID2 VID3...
TABLE :
VID3 VID2 VID1 VID0
1 0 1 1 1.5v
1 0 0 0 1.65v....etc
if u ground the VID1 and VID0 to VSS pin which is near the VID pin..u will effectively increase the vcore to 1.65v which enable my CII 566 to run at 850mhz...damn stable...
other voltage like 1.60 and 1.55 also can be done by this way...unluckily...1.70-1.85 is impossible to be done...onli 1.90v can be modify....which is a bit risky...and this method can be apply to PIII cop also...
how to gound??? ha... i use a s. tape or double side tape and little piece of soldering iron(2.5mm long) and simply tape at the back of the motherboard socket370 pin... and now i run at incredible 850mhz @ 1.65v...seti@home for 1 day+++....and well good job DFI's guy, the board is damn stable too....
anyway...i warn u...this will definitely void ur warranty....use at ur own risk...
any question to ask simply msg me... sweetpotatoes_2000@yahoo.com

CII566 @ 850 1.65v(modified) DFI CA61 mobo
might run at 875mhz(crashed once while play counter strike )
