A64 2800 would it run at 1.2volts?

Could you just buy an athlon64 and run it at 1.2 volts?? i just want a cool running CPU and buying a real mobile is proving to be a huge hassle.

Use cool and quiet?

No i plan to use F@H

Ill probably just have to wait for the 90nm desktop a64s blah!

I am not sure since my motherboard only has lower adjustments to 1.45v for vcore. I was able to overclock my 3200+ to 2.35ghz at 1.45v though, so I assume it might work at 1.2v if you can find a motherboard that has voltages down that low.

maybe. if you don't want to use cool and quiet you might be able to get the voltage down that much.
since it's hot here in the summer i run mine at 2GHz at 1.3 volts. with my new ower supply for some reason the voltages are dead on at normal voltages, but it runs it at 1.26 when i set the mobo at 3.0

ive tested it with sandra cpu burn in wisard and it is table at 2 GHz at 1.26 volts. a 2800 would have a better chance to do 1.2 V than a 3000, but i think my chip is pretty lucky
it's a co stepping newcastle

hope this helps

Makes you wonder why, if AMD chips can run at voltages that low, they ship them at 1.35 to 1.55v stock?

 

[iwantanewcomputer]

while i'm at it, i might try underclocking it to 2800 speeds or lower and seeing how low the voltage will go
will post results later on

Thanks

I may get this thing built soon now with your help.

anyone know what voltages the .09 micron chips will have? Provided they dont have the leakage problem the prescott has youd probably be able to have a super quiet PC and still be able to overclock it since it doesnt run hot.

 

[iwantanewcomputer]

to answer yanagi, i heard that leakage problems like the prescott are getting worse in 90 nm, even though the voltage is lower. the main reason they aren't out though is that amd can'y make them as fast as the 130 nm chips yet. they can get them stable at 2 ghz easy but can't make more than a few that can do 2.6

results of my voltage testing:
I tried testing mine at 1.20 V at 2 ghz-no go
underclocked to 1.8ghz(2800 speed) it booted up. asus probe measured the voltage at an incredible 1.16 volts, and it passed some benchmarks just fine! the temperature monitor showed the temp of the cpu dropping as soon as i loaded it. when it stableized under load the temp was at 37 for the processor, 39 for the motherboard, with a case temp of 34i haven't played with cool n quiet yet, but this will stay pretty cool in the winter.
