Lower voltage on an e8500

[mpj88]

Hi, just wondering if there is any thing im missing with some settings in the Bios to try and bring my core voltage down.

Im currently using an fsb of 480 with a multiplier of 8.5 (so at 4.08ghz) and to achieve this im using 1.392v (reported in cpu-z) if i lower the voltage in the bios anymore it fails prime. However i have seen people clock their processors to this speed still on stock volts. Am i missing something or is my proccesor just not very good and overclocking!

I have manged to get it to 4.5ghz but that used a fair amount of voltage and prefered to keep it below 1.4v for daily use.

Thanks

It's hit and miss i am afraid. Mine needs 1.4v for 4.5Ghz but only 1.275v for 4Ghz. You need to play around with other voltages as well but don't go mad.

DFI i see.. hmm... picky motherboards

try increasing VTT voltage and both chipsets, north/south

as about your volts they sound just about right.
but also have in mind that although these volts are needed for 480 bus.. it may even be sufficient for 490 or even 500

but generally its all about finding the sweet spot for your cpu.

my 8400 for example runs at stock up to 3.5ghz, it needs just +0.025v for up to 3.8ghz
and then from there up to 4.5ghz the volts are increasing expotentialy
i.e. 1.3v for 4.1ghz
1.35 for 4.2Ghz
1.45 for 4.3
1.55 for 4.5

I think you get the picture.
generally i found on my dfi that help keeping the VTT volts close to cpu.

hope this helps a bit.
good luck
