Underclocking

[krooton]

I'm inheriting the following, and thinking about making a wee media centre out of it:

Socket 478 P4 2.8Ghz
Asus p4v8x-x
1GB DDR400
Radeon 9550

Now the TDP for the cpu is 64w, but all this box will be doing is outputting video to a tv or playing mp3s, and I'd like to minimize the power draw.

Does anyone know if this cpu and mobo will allow for underclocking? And what sort of wattage saving could I look at running it at 1.6-2ghz (or less if it can still do video)?

Ta!

very limited potential to drop the volts on P4 mobo - and any intel ones really
Clock and multi is easy but as Audigex said it's all about the volts.

Worth a look - but AMD's are the underclocking kings

Edit: just check the users guide 'auto' and 'over voltage' are only options

Doh!

Well, free is free, can't really complain.

Maybe I will see if I can sell the mobo and cpu and get a cheapo socket A mobo/cpu, they undervolt pretty easily as I recall.

Thanks for the head's up!
