This is with uncore set to 34x on F9 on this board. It runs at 4GHz and idles at 800MHz. (4670k)


I started to flash back to F9 but got the message about Qflash being out of date. I'll stick with F10 for now, running the uncore at 35x doesn't really bother me. I won't hold my breath since they seem to have their hands full with x99, but maybe GiB will update the next BIOS eventually.

Thanks.

I have Z-97P-D3 board and Uncore only drop on auto at idle, tested on latest bios F6 and previous F5.

cpu-z is useless unless you use an old version from like a year and a half ago because they're still showing the VID instead of vcore. Many other programs use VID instead of vcore, too - some even label it as "Core Voltage" etc, when that's not what it is.

Also manually enable c6/c7

I use multiple utilities and they are consistent with the readings. If I set the CPU vcore to auto, voltage would drop at idle but if i set it to manual it doesn't. The utilities also properly read if i set the CPU vcore to 1.2v or 1.3v so I know it is reading correctly.

I tried doing that but it didn't made any difference. I also tried enabling every single power save feature for the cpu but it didn't made any difference.

Try using HWInfo instead of HWMonitor.

http://www.hwinfo.com/download.php

Shouldn't matter, but do you have Balanced set for your Windows Power Plan?

I told you already I am certain my utilities is reading the voltage properly

and yes I do have windows power plan set to Balanced. Also tried setting it to power saver but it didn't made any difference.

All of these utilities read CPU VID, which is -NOT- cpu VCORE!

We're not wrong. If you set 1.3v for example, it will even be 1.32 at load due to an IVR behavior.

On manual voltage, the CPU VID mirrors the value you type in the bios (but not the actual voltage, which differs from that). It also drops to other values in idle states, but it's the VID. VID is not a voltage. Vcore is the voltage, and there are many VID sensors mislabeled as core voltage and vcore

I just realized that there were 2 different F10c BIOS for the UD5H. One is dated April and one June....anyway, I flashed the June dated one and now the uncore on Auto will reach 40x, and although it will not idle down to 800 it will go as low as 1600 at idle. So I guess I'm pretty happy with that.
There is still a bug in this one where the bus needs to be set at Manual and 100.01 for it to reach 100, however, but again no big deal.

If i use the "An Easy 4.4/4.5/4.6GHz Template" should i touch uncore frequency or any other setting not listed there.
It seems important from reading the parts earlier on but im not sure using the template means i don't need to do anything else

PS: In computer system properties it shows stock speed, but in programs like hwinfo64, hwmonitor and cpu-z it shows 4.6ghz
I think this is because I have only changed the CPU mutliplier as mentioned in the template, is that alright?

Thanks

Edit:
Gaming at full load peaks at 84C @ 4.6GHz, average 68.8C over 10hrs+
Idle is around 43C

Temps look alright but could do with second opinion. My cpu is 4670K, with NH-U12S cooler

Don't need to touch uncore, if you tweak it then it's good to just use ~0.1v less than vcore, and whatever multi is stable with it. My gigabyte board when uncore is set to stock (35 on 4770k, 34 on 4670k) will give 8x at idle, 40x at load on the bios that i have, so i just use the voltage that i need to stabilize that, instead of running ~33x 24/7.
