Undervolting - Is this bad?

[The Pentium Guy]

Just wondering if Undervolting is bad for your CPU.
For some odd reason I can make my prescott (478) go from 1.33V to 1.30V, but it makes one HELLOFA temperature difference (it's lower when you undervolt)

Just wondering, is it safe/will it have any bad effect?

The only bad thing that could happen is the CPU could become unstable. Run prime95 Small FFTs for 10+ hours, SuperPI 32m, and memtest to make sure you are still stable.

if it's stable, it's stable

Heh. Stability eh? My system begins to throttle when at normal voltages. That's why I'm undervolting . I got some AS5 and some fans coming in (tomorrow or the day after), so it's just a temporary thing.

Thanks though.

if that's so, then maybe it's better for you to undervolt

Nope,that's exactly how AMD's cool & quiet works,that with lower multipliers.

but there's no reason for you to not try undervolting,keep reducing until you get stability problem then bump it back up a bit to regain stability.

I am running a 1.4v San Diego at 1.35. It is stable OC'd to 2420. It runs about 2*C cooler undervolted and overclocked that it does at stock.

NO.


As long as its stable your fine.

Run prime for 24+ hours.

I don't think so. When I run my Venice 3000+ at stock speeds (1.8GHZ) I drop the voltage down to 1.2v from the stock 1.4v. Works great, uses less power, makes less heat.
