For example, if I set Turbo LLC and that same DVID at 4.5 offset my Vcore is 1.23v---I bet that's not what you get.
To your case cooling; just don't use the case. Not until you know how well you cooler works on its own, which you probably have no idea about right now.

Sorry, I meant to include the VCore as reported by CPU-Z. It fluctuates between 1.224 and 1.236V under full load. Unfortunately I don't have time to remove everything from the case to see what my temps look like. I'll probably invest in some nice, quiet case fans. My exhaust fan pushes a lot of air but it's pretty whiny and lately it has been driving me nuts. Any recommendations for nice, quiet 120mm fans?

Oh, then 1.23v sounds pretty normal for that speed.

Is it hot in there? You might have an issue with the 212, or case airflow. Open the case and leave it on it's side for an hour of Prime. If it's not any better then pull off your cooler, check your paste coverage and reapply with a little bit less than pea-sized blob.

yes ,that's what Offset Mode will do (see the link in my sig)

What other programs are you using to measure temps?

BTW, speedfan is working for me. You have to go to advanced, select IT8728F, and set pwm mode to software controlled.

What do you have for BIOS settings?

I still have one question:
What's the explanation for the mainboard's higher power consumption (UD5H)?
Here from an older review.
Shouldn't a highly efficient vrm solution consume less than the other?
Are the things changed with the one of the latest bios?
I don't really mind since I still however love the Gigabyte products but what should I explain to the others (on our Italian 3d's) thinking of the UD5H's less efficient power consumption as an inferior vrm issue? thinking.gif
Well let's consider this, In the USA at least, the UD5H is a freaking loaded motherboard for the price, it is hard to find a board with more features, so many little ICs, so many power consuming chipsets, there is VIA controllers for 1394A, so many extra SATA controllers from marvell, dual NICs which aren't light on power either. Now here is where the UD5H set's itself apart from all the other boards.... get ready for it, it has two on-board audio line-drivers, which are amplifiers!!!! if those don't use power then your sound wouldn't sound good. Now Maximus 5 Gene, just is a simple ALC898 like the UD5H's ALC898, but the M5G has no amps, just more standard capacitors which don't consume more power.

Also the less phase count you have the higher efficiency you will have. What manufacturers like to hide is that higher phase count=higher number of switching components=lower efficiency. So the 6 phase UD3H will have higher efficiency as the 12 phase UD5H. Other than that the switching frequency has the largest impact, and on the uD3H and UD5H is it set to around 300khz which is pretty low. I know it doesn't need to be increased under OC, but on some other boards it probably is increased.

What is interesting is that you can clearly see how bad MSI's VRM design is, your best board should be getting the highest power consumption if you use the same phase quality throughout your line, I am pretty sure the Maximus 5 Gene uses same VRm quality as the P8Z77 line, thus making its 8 phases more efficient under idle conditions as there is lower phase count. THis is evident in the GB boards as well, as the UD3H is higher phase quality but lower phase count as the UD5H, but same type of parts and arrangement, with minor difference in MOSFETs to make there a big difference in power consumption.

Also there are 3 MOSFETs per phase, while this increase the number of switching components, it also helps temperatures and power output greatly as well, these VRMs are built for highest performance. If you want good effieicny, then just run it


BTW maybe tell your friends to protest for your reviewers to buy two of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16811999227 modify them, and use them to measure CPU power consumption off the 12v input for the motherboard, that is how I do it :0 and that is the only way you can start to conclude on VRm efficiency

This club helped me decide on which mobo to get for ivy. I've been a long Asus user until my last RMA with them turned sour..So I ditched them and went with the z77x-UD5H.. Not to mention the awesome Gigabyte RMA experience!thumb.gif
I am coming from an i7 920 so this will be a great upgrade for me!!

You will have fun.

1.4v i believe, sorry. You should have more raise with extreme and less droop with the other settings than mine, but very small amount difference.

I have just put together my rig, along with the UD5H, and I'm running into a problem where the mobo will recognize my 1TB HDD in the BIOS, but not my Mushkin 128GB SSD. I have made sure the SATA cables are connected, as well as the power connector from the power supply, but to no avail. I don't believe there is a difference between the blue SATA cables and the black ones, just the ports where they are plugged in.
I really want both drives recognized because I want to install Windows on the SSD.
The motherboard BIOS is not updated at all, this is a stock mobo. TO be honest, I had to remove my graphics card in order to even get the BIOS to show on my monitor.
Any help to get my SSD recognized would be awesome!
Thank you!
Try one at a time.

What's strange is that I tested the vcore with a multimeter and on load it was a fairly consistent 1.150v so I wasn't getting the temperature benefit of the lowered vcore. On idle it was 1.140v. I thought that raising your LLC was supposed to make the vcore consistent with your manual setting? This is with all other settings on default except for Intel Turbo Boost is disabled. I believe I was still about 5C lower than if I had vcore and LLC on Auto so I am making a little progress.
LLC is the reverse of drooping under load, it reduces that drop under load. Basically there is an equation, and the slope in that equation is what LLC controls. The equation is for drop of voltage under load. So basically the slope increases until the line is straight, and then keeps going one step so you can basically rise under load at voltage below 1.5v, however above 1.5v LLC extreme will droop a tiny bit like at 1.9v. It really is best to use LLC turbo for air and water OC.

I'm thinking it may be something dumb, like I may have plugged a SATA power connector in, but there is no power going into it...I don't know!
You mean into the board or the SSD?

I think others answered this, but set your VCore to normal, and then set DVID.

AHCI is the stock setting.

First just install windows on your Mushkin, if you unplug your other drive, and just plug in the mushkin is it recognized? if so then install on it.

Guys I picked up a Z77 DS3H... and i can't find any vcore adjustments (what?!). I read on another site that this board doesn't even come with vcore voltage changes?? My $40 biostar board even allows you to change vcore you got to be kidding. I heard though that newer bios versions allow vcore changes. I updated from F2 to F5 (and F4). Still don't see any vcore adjustments in voltage.... please help, this board is frustrating me.


Seriously... can't believe they would not allow such a basic (arguably THE most basic) adjustment. why in the world are they doing this?

That went over my head but I will try LLC turbo and see what happens, thanks for the tip.

Sure enough, set it to 1.135v with LLC Turbo and the multimeter reads 1.135 on load. The question is whether I can still pass Large FFT at this voltage. Hope so! Just for another example of CPU-Z giving the wrong voltage, it's telling me that it's running at 1.116v right now.

I couldn't even get Easytune 6 to work, it would crash after running for a bit.
