P III 850@1190mhz 1.95v... -18c...sub zero voltage limits??

[woofer]

Hi,
Im using the new Vapochill Socket with my P III 850@1190mhz 1.95v . It is totally stable in all apps and temps are -20 to -14 max .

I have read that once you attain SUB ZERO temps you can increase the voltage higher than you normally would when using AIR cooling, can anyone give me some input as to wheather they consider this to be correct , and is 1.95v at -18c overly dangerous.

What would be a maximum LONGTERM voltage at this temp? ( -18c )

Any input would be greatly appreciated.....

As CMOS state becomes colder, it's ability to perform increases. This means that you should be able to increase the FSB more and more as things become colder.

You may even be able to drop voltage.

However - there is still a limit on how far you can go with your chip.

I wouldn't be happy to keep my chip running at 1.95v if it were air cooled (warmed!), but I'd be happy to keep it running at 1.95v under a constant sub-zero peltier or Vapor Chilling Unit.
