1.64.0 is the best version of cpu-z for haswell.

Software voltage readings are not neccesarily accurate

Really? I'm on 1.67 and it's pretty darn accurate! I thought it was 1.65 where VID was sorted?

So one for mobility and one for home use, nothing in between.

I've got a laptop and this massive desktop. This is going to for my wife to use as well as hopefully some LAN parties. It's more general purpose than Ze Cube. I don't plan on going crazy all out like I did with it. Mainly just going to be re-using the parts left over after build Ze Cube.

Using a Gigabyte Z87-D3HP, the one from the review where I pulled this SS from. Using CPU-Z just gives me the VID. Using HWMonitor or HWInfo gives me my proper vcore of .8 or .7 or whatever. I'll try setting it to Enabled.

But it is possible. However, CPUZ's voltage readings have been suspect ever since Haswell came out, and have been misleading for a long time. Not sure if they fixed it recently though. I still use HWmonitor to track voltages.My power supply is not super duper old but it's before Haswell's time.
Forceman may have mentioned Gigabyte board as IIRC they have wonky power control settings.
The c7 point will now be listen in the guide. (Further clarified)

Ah so I HAVE to leave adaptive on? Cannot afford that at all. But I don't have an adaptive setting for voltage control on my board. At least I haven't looked around and found one. Just an Auto ( which I presume is adaptive ), Normal ( which allows me to use offsets, which are highly stupid, because they give even more vcore even when I'm undervolting ) and the voltage setting ( which I use for setting voltage.

I'll test later today and see what happens when I set everything to default in BIOS and such.

Most people undermine Gigabyte, but their low-end boards have an excellent power delivery design, with the mosfets and caps that they're using. I'm talking about ROG standard (forget about their high end boards). The only thing that kills them is their bioses and non-user friendly bundled software, easytune, etc....

I had the 1.64 x64 version, but looked around and people recommended the 1.64.1 version. Either way, the former gives me correct vcore but incorrect bus speed ( well, that's alright, since I don't touch it anyway ) and the latter gives the correct bus speed and the VID instead of vcore. And I totally agree with you; the board is excellent but the software is crap.

That version of CPU-Z is the only on that gives the correct vcore along with hwmonitor and such.

But that ES chip thing. Maybe that's why AT's review said the S0ix idle states weren't available on the desktop chips and I think that's what it referred to.

As for SFF, I wanted to use my previous mATX case, but couldn't get a board when I was getting my haswell parts otherwise it's a very potent PC for BYOCs and such.

If it's a Gigabyte board, you'll need to manually enable C6/7 along with the regular stuff (EIST, C1E,C3) to get those drops. You can check it with HWInfo (down at the bottom, not the VID reading up top).

I'll give it a look-see. Thanks

I've said it before and I still say it.. that's a myth. Haswell does not go that low, not even Intel's own XTU shows that - it shows exactly what all other tools show (as long as you're not using a very outdated version of CPU-Z).

cpu-z and hwinfo show me the same "vcore" sensor which is ~0.02 higher than VID at load and drops to ~0.7-0.8v or below that and weird/unreliable readings in c6/c7

cpu-z 1.64.0 is the only one i found recently out of like four i tried that show a sensor that's not VID. VID is quite useless for OC'd CPU, because it's always exactly what you set in the bios (at least on gigabyte) so it's useless as you already know it and it never changes

Same here vid is always the same as bios setting and I have a Asus board

What Forceman said. If you have a Gigabyte board, no adaptive is needed, you need to tweak the other settings.
