Overclocking CPU's and voltage levels...

[DK_UK]

Hey there,

I tried pushing my San Diego 3700+ up past 2.6Ghz today, but everytime I entered XP it gave me a blue screen then rebooted, if I reduced the speeds down to 2.5Ghz ish, it was fine.

I just wonder if I increase the voltage slightly, it may run more stable?

At the moment its at 1.400V I tried increasing by 1 increment to 1.425V and it still crashed. How much are you supposed to increase it by in order to be "stable".

The temps are fine, 45C when checking in the BIOS.

upto 1.6v m8, but make sure u have decent cooling and air flow. ump it up .25v each time until stable, but other factors infurence it as while such as ram speed/voltage, et...

Cheers m8.

In the end I only had to up it to 1.475V and all seems fine now, been running it at 2.6Ghz and so far, no crashes or hangs. Just running the Prime95 "torture test" to check for errors, 30 min and no problems, so all looks good! :D

i think the "done thing" is to run prime overnight to check for stability...

yeap.... on blend test I believe.

indeed, although there are folk who have happily run an overclock with no glitches but the machine is not prime stable...
