Questions about voltage

[Tim]

I was wondering what the best course of action is for setting voltage for my CPU is.
When I launch coretemp, it tells me the VID is 1.1125v. Is this the voltage I should set it too?
I know that whatever I set the voltage to in bios, it will natually be lower due to vdroop, right?
Should I set it in the bios to where it shows as close to 1.1125 (VID according to coretemp)?
Help me out here. I'm guessing I should use CPU-z to tell where my voltages really are.

okey that number you see on VID is the stock bootup voltage on the chip.

That VID tells your nice board what voltage to give on auto so the chip can run stock settings.

B4 we tell you whats okey and whats not, tell us what YOU want.

What is your goal oc, and please dont say the sky is the roof.

What is your cooling system, ie what kind of sink you running.

A vid that low leads me to think you either have a wolfdale or a yorkfield or a really great Q6600.


Also im guessing your VID changes as you drop multi.

Meaning if your stock 9x vid is that high, you drop multi to 8 and your VID will change.

It's e8400 wolfdale as the topic summary should say. My cooling setup is a mcr-320 rad, mcp-355 with XSPC top/res combo, and EK Supreme cpu water block. (a EK northbridge block is also in the loop after the CPU)

I'm just trying to understand the voltage situation here. My motherboard (evga 680i) does not set the voltage anywhere near the 1.1125 VID that coretemp shows, It seems to be content putting it at around 1.19ish.

I plan on keeping this at stock speeds with the very ocasional overclock, so the lower the voltage I can keep it at with stock speeds, the more healthy my CPU will be... at least that's how I understand it?

then start dropping the voltage. Problem is you cant set it @ VID because of something called VDROOP.

So you need to manually find out how low she can go with vdroop applied by testing it prime or OCCT, and then dropping it again.

Set it at 1.1125 in bios, CPU-z is showing it "vdroop"ing down to 1.072 under load (running ORTHOS Prime)

How long should it be run to be considered stable, a full 24 hours?

Edit: 22 mins and counting thus far just fine
