Celeron II Safe MAX Voltage

[Werty]

hello & sorry for this old question. im currently running my Celeron II 850 => 1.113Ghz @ 1.85volts. temperature is 40-41 on idle, and 49-50 on FULL load. i would want to give it more power, but is 1.9volts still safe for this old but trusty CPU? how much voltage is considered enough?

whats stock voltage 1.65, 1.7?? on a .18 micron, im jsut guessing 1.9 is highest i would go.

default voltage is 1.7, based on coppermine-celeron i think...

1.9v should be fine, I ran the same cpu overclocked at 1190MHz for several years, no ill effects.

I've run 1.89v (set to 1.85, mobo overvolts) using a Celeron 800@1066 in a Shuttle SV24 system. Actually I've done three setups like that. All have run fine for 1½ years, except for one of them that I sold and the new owner promptly got a 1.2 Tualatin Celeron on a socket adaptor in there faster than you can say "lower FSB." I'm just waiting for him to ask me to volt/pin mod that puppy for 1.6GHz.

any links about this voltpin mod?

Download the PDF datasheet:

Intel Celeron datasheet (.18u, socket 370)

Page 20 of the datasheet gives you allowable voltages. You said your default voltage is 1.70. Looking at the chart on page 20, you can easily get 1.90v by connecting the VID2 pin to VID3. Reading the chart, a "0" means there is voltage and a "1" means no voltage. Very easy to convert a "1" to a "0" by connecting it to another "1." To convert a "0" to a "1" you would have to insulate or break off the pin.

Page 97 of the datasheet tells you where the VID2 and VID3 pins are. Hold your CPU with the pins facing you and orient it so that the corners missing the pins correspond to what you see on page 97. Look at the top right corner pin. The two below that are VID2 and VID3. Just get those two pins to somehow be electrically connected, and your motherboard will magically give the CPU 1.90v.

To connect the pins, you can drop a "U" shaped fine wire into the corresponding holes in the socket. You can also use a fine wire to connect the two pins by wiring them to each other. You can also use conductive ink (typically found at auto parts shops as "rear defogger repair kit") to connect the two pins together.

done it, but i didnt gv it much juice.. just enough to avoid the "cool boot" problem just as another link suggested
