Voltage Issue

Hey,

I am trying to set a good voltage for my e8400 @ 3.6ghz, im aiming for around 1.24/1.25V as i know that it is orthos stable at that voltage (due to past overclocks on this motherboard). I have a DFI DK-P35-DS3L and the voltages are given as +mV amounts from the starting core voltage (~1.15v) so if i select +87.5mV, cpuz reads the voltage as correct (~1.2375V). This isnt an orthos stable voltage so i try to up the voltage from +87.5mV to +100mV, however, cpuz doesnt display 1.25v as expected, instead it displays 1.28v which is probably a bit overkill. A few weeks ago when i stepped the voltage to +100mv, it worked, but now it wont.

anyone know why this is?

edit: today cpu-z is displaying 1.296v, it seems to change with every boot which is a pain

Welcome to OcUK forums mate

What CPU-z version are you using?

It could be down to any hardware changes i.e. more/ less drain on PSU if you've upgraded recently.

Also, VRMs, CPUs etc do wear out. Might just need a wee bit more voltage as its getting older

Don't worry about the numbers - put the voltage up to what it needs to run stable. Looks like you gave a low VID chip anyway so you'll hardly be thrashing it. Are your VTT & PLL settings still the same?

Try looking into BIOS updates to see if there's any benefit to be had with an update.

thx for the advice mate, bought my e8400 about 3-4 months ago so its new, and the board ive only had for about a month, i was just being pedantic when wanting ideal numbers, but was worried as u say that it could be a sign of wear on the cpu.

thankfully it is running fine, i will look into bios updates and as far as i know im on the latest version of cpuz.

may push for 4ghz later, this was 1 of my only worries before i tried it since im running at 40degrees full load at 3.6hz and that seems fine for an arctic cooler 7 pro.

thanks again, and suppose uve claimed me
