I can't really give you a reason other than that's the way the boards power delivery is set up. I don't think anything is necessarily wrong with the board.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

I am not saying it's wrong either, but I don't understand how is the offset supposed to work then :)

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

you've tested with all llc levels?

whats your chips default vid as in when you set cpu v to normal what amount does it use in the bios?

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

I am not using any LLC at all.
In the BIOS, the 3D core something section, VCORE says 1.085V on normal and normal+offset both.

I did notice something though: when I eliminated the offset, VCORE reported in M.I.T. screen went from 1.008-1.020V to 1.056-1.086V, so there IS a change of some sort.
What's absolutely weird is the identical VCORE reported by CPU-Z no matter if it's idle or under 100% load.

in windows power saving options,try setting to power saver profile then look in cpu-z at the voltage used see if it lowers

Maybe I am missing something, but could someone explain how the DVID offset really work?
I thought it would universally lowered VCORE, but... I originally used -0.045V, but recently found some instability and started testing again, and noticed something weird. I kept going towards zero, and neither min nor max voltage changed one bit. I even switched from normal+offset to pure auto setting, and there's exactly zero difference in VCORE under idle and load both.
Is somethingh wrong with my board?

I can as far as I undersand it. It goes something like this...

Just playing with my system . In ET6 you have a power on voltage of say 1.290v (bios shows 1.200v so I guess the chip calculates this voltage based on the multi?) Then if I add my dvid voltage of .020V to the power on voltage I get the target voltage of 1.310v. Then using a LLC of high my load voltage drops to ~1.272v. If I use a extreme LLC my voltage runs ~ 1.308V If I use a low LLC my voltage drops down to ~ 1.232V. But I know I need at ~ 1.272 volts to be stable after testing using just vcore. So for me thats what I target when using dvid and LLC.

Using the low LLC to reach my target of ~1.272 I will need to raise the DVID or change to a higher LLC. By the same token if I use LLC of extreme I am over my targrt of ~1.272 go I would need to lower the DVID to reach my target or lower the LLC...

So for me I use an LLC of High and a DVID of +.020 to get me to my target of 1.272 under load. If I went to Turbo I may only need a DVID of 0.00 I don't know off hand...But I do know it will be less.

Does that make any since?

Are all the PWM fan connectors supposed to behave the same way? Some don't even seem to have PWM enabled on them at all. Like fan4 or fan5 connector, it spins a fan to its max no matter what I do. That's my first WTF.

Also, how exactly is the PWM function supposed to work anyway? I thought more voltage was being pumped in according to temperature in the case measured who knows how. Well I have two 140mm Scythe Glide Stream fans in my PC that start at 500RPM when the fan control in BIOS is set to silent, and 800RPM when set to normal. That would make sense, if... if the speed raised significantly under load. Right now I could cook a chicken inside the case, and the fans only increased their speed to 620RPM. That cannot be working as intended.
Normal mode would be fine if the bloody fans didn't start so loud even under zero load.

Did anyone ever have to raise IMC voltage by a LOT in order to make pretty much any overclock stable? With my 3770K I had to go from the default 0.925V all the way to 1.050(!!!) to be Prime stable. Really weird, and I have no idea what to make of it. It could be memory specific, but I couldn't google a single instance of similar behaviour.

No, I can't say that changing IMC voltage ever helped or hurt me.

it wouldn't surprise me with 16gb of memory,it depends on how good your cpu imc is and what make/model of ram your using and how well its supported by the bios ect

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

I couldn't google a single instance of anyone having to siginificantly raise this in order to be stable, and yet I have to go all the way to 1.050V from default of 0.925.

Re: ***Official***Z77X-D3H UD3H UD5H Discussion\Owners Club***

Hi all. I'm having a problem with my newly assembled pc. I bought the Z77X-D3H and a I7-3770K CPU.

The board started with an F6 BIOS, and the PC was working fine, but that BIOS version does not support my CPU. So i upgraded to the most reasont BIOS (F16), which gave me quite a performance boost.
After the upgrade the pc will not shut down. Windows does close correctly and my monitor does go into sleep mode which means there is no signal coming from the graphics card, but the CPU fans and chassis fans keep on spinning.
I then went back to the F6 BIOS, and the problem went away.
I then upgraded to F7, which is the oldest version that supports my CPU, and the problem came back.
I dont think this is a PSU problem as it works on the F6 BIOS.

Any advice?

Thx in advance
Jesper

Could people give me a few examples of 2x8GB of 1866MHz memory they personally tested with UD3H without any problems at all please?

I increase IMC to 1.050V... in 3 days 2 BSOD + 1 freeze in BIOS... same problem with more VDIMM and CAS 11.11.11.* : always 1 or more BSOD per week with my Crucial at 933MHz (4x4Go PC14900 CAS9).
I return to IMC default value, Crucial works fine at 800MHz with CAS 8.8.8.24 and 1.50V.
