The "Undervolting" Guide

[flipfire]

Your preference, there wont be much temp difference between 600 and 800mhz specially when they are running within the same voltage

Set it at 800mhz if you like

yes it is, i was able to undervolt my T2500 core duo (yonah). the annoying thing was, it had like 10 multipliers to tweak.

Thanks, just for complete 100% clarification, for those that have the XPS M1530, have you successfully been able to change the voltages/undervolt?

And has anyone successfully used NHS/RMClock with their M1530 - not to monitor anything but to succesfully change voltages/settings?

Once again, I have the T8300 CPU. I am just making sure since for those that know DELL, they may have blocked it in their BIOS.

Thanks so much for those that answer this, just need this answer to clear all my confusion and my distractions.

Yes, 99% sure you should be able too. I havent heard of manufacturers blocking UV'ing in the BIOS so far. Lots of T8300 have been successfully undervolted. Why dont you just try it for yourself?

If you using XP you can use NHC but for Vista you have to use RMclock

I will be able to very soon, haven't yet received it

Perfect, done deal, thanks that clears that confusion up.

Just for clarification, through which program are you undervolting it?

PS: Whenever you have the time, I'd love if you could share the voltage measurements you set, that be amazing.

THANKS richierich!!!

I'm using the best out there: rmclock

So far I've been very happy. Slowly testing each multiplier. Right now stability testing 10x 2.0GHz @ 0.950V. 2 more multipliers to go, and I'll post my settings.

Soo with that CPU stress program, if I test it for 20 mins and get 1 error in one of the cores, should I go back to a higher voltage? Or is having 1 error ok?
It just seems that my undervolt is really bad, I cant even go down 0.1000V without getting an error in the stress test

So there really is no way to go lower than the capped voltage in rmclock?

No because Intel/AMD locks the voltage min. temp, that way there is a safeguard in place.
