OK...I just ordered a UD5H with 3770k. Hopefully things go well and I don't regret getting the UD5H over the P8Z77-V...

running 1.310 vcore in the BIOS
1.308 @ 100% load in CPU-z
LLC on extreme

Max temps 67*
just passed the 10 hour mark in prime95 blend using 90% of available RAM.
Definitely interested in running offset if it can net me the same clock with lower voltage.
One thing that may get the voltage down now is to use a lower LLC,
But to use DVID Just set vcore to "normal" then you can type in the offset. Start out with something like +.010, and set LLC to High. Depending on how your cpu reacts from there you can either up the DVID or up the LLC. Those settings are good enough for a stable x45 clock for me, but every cpu is different. My vcore max 1.260-1.272 depending on how I set it up.
I usually monitor with HWINFO, there is 32 & 64bit versions and seems to respond to vcore changes faster than some other monitoring programs. All I run is the sensor panel and I configure it so it only shows what I want it to so I can fit it all onscreen.
EDIT: I also use Real Temp to monitor temps.

gotcha, HWmonitor doesn't seem to work for me?

where you located in FL? I'm in fort lauderdale area

Some droop is not a bad thing, but obviously if you can't run stable then you need to make changes. The LLC on these boards is fabulous IMO and finally on Gigabyte boards we have both DVID & LLC working together (if you want to go that route).
As an exercise I proved that you can actually run a +0.00 DVID & get a stable x45 OC just tweaking the vcore LLC. However this didn't allow me to reach my lowest possible vcore. Check out LLC with the different settings and monitor the vcore under load with each and you'll see that it's a handy tool.
Or maybe I misunderstand you completely in which case disregard. wink.gif
I'm sure your comments apply to my situation, I don't understand how any of that works but I will research it. You've given me a starting point so thanks, hopefully it'll lead to some good results. For now I've given up on manually setting vcore cause it seems to give you a voltage much lower than you entered, so looking into these alternate methods is where I'm headed next.

If you don't want any droop during load just set the LLC to turbo or extreme. At extreme you shouldn't experience any droop at all. If you put 1.200V it'll be 1.200V at all times. I have mine on turbo. For a 1.100V setting CPUZ reports 1.092V under load.

In your case it should help with your stability if they voltage is dropping too much for the chip to stay stable during load.

Have you tried HWINFO? It gets regular updates. http://www.hwinfo.com/
I'm in Suwannee County, near Live Oak for last 30 years, but Lakeland is my home town.

Is it worth extra $50?
Also whats the power phase on two board. Also have they fix cold boot bug. I had problem with getting 4.8Ghz OC on my ASROCK mobo.
I'll be forever thankful if you can answer my question.
Well the GB boards have no problem giving you the best OC out of your CPU. I would get the UD3H over the D3H if not only because of all the OC features you gain, such as the buttons, the voltage read points, the POST code, the extra power connectors. It is a much better board for high OCes. However the 4-pin power connector wont hurt your OC>

If that's the case, I know some CPU's can be very sensitive to a higher BCLK, while others will go to 103+ with no problems. So this would actually make sense if they had bumped this default value trying to get higher default scores...and yet have a decent amount of people with freeze/lock-ups because their particular cpu is sensitive to higher BCLK.
Default spec is 100.00 with a +/- certain percentage range, something like .1-.2%. in retro spec i actually think it is +/- 5-7% for OC, so 107mhz. But i can push 115 on all the GB boards smile.gif, that is some fine tuning. At stock there is a BCLK swing from the clock gen inside the chipset which naturally occurs, that is why you se ethe BCLK go up and down 0.03mhz somtimes. As the chipset provides the base clock, and its clock gen varies up and down. As for the new BIOS updates which should release soon. when the BCLK is set to auto it will be closer to 100.00. Right now if you go int on the BIOS change change it from auto to manual ti will set 100.00 exactly, on auto it gives you a slight boost.

The lockups, honestly mate, if you knew how many boards have sold since day 1 you would think the percentage of people complaining would be very small. Also the BSOD thing is also related to software, which is pretty odd. If you don't have windows 7 updated then you can be at risk, which i think accounts for many of these issues. Also other boards have this issues as well, their just aren't many buyers compared to the GB boards, because of their price and the price of the competitor, many more users are buying GB this round than last. I have seen reports from the asus P8Z77-V series of the idle BSOD, I actually saw one on these forums, but i can't find the post again, perhaps it was in their mega thread. I had this happen with a 2500K of mine on one of my UD5Hs, however I did a lot of testing, the idle BSOD after optimized defaults were loaded only occurs at stock and is totally software related, and I found out doesn't occur in Windows XP. My issue was that my Windows 7 wasn't updated at all...... So there can be two problems, one software related and one with the BCLK OC that GB provides at stock, the BCLK will be taken care of very soon. The software one tho, that is up to the user.

However if you have this issue it could also be that there are a batch of early boards that exhibit this, in that case RMA the board and GB will send you one without issue.

I guess I have been super lucky that I have not had one BSOD, lockup or any stability issues since I got the board, compared to many other threads I have seen on various forums and on newegg. To be honest if I had waited to buy my mobo and saw all these reports I am thinking I would have went a different route, but in the end I am happy with my UD5H, it does everything I want and more, and for the price is great.

You aren't super lucky, you are just part of the 98% who don't have the issue at all. GB knows what is causing 90% of the BSODs at stock and that is the BCLK, so thus in newer BIOS updates the BCLK will be closer to what ASUS has set, i think 100.1 or 100.3 instead of 100.7. You wont see many more people complain of it.

THere is also this, which has been bothering me, a lot of people have degraded sandy bridge CPUs, some CPUs especially sandy which degrades super quickly, loses its ability to be stable in stock conditions. THis could have happened to my 2500K, but i doubt it.

Thanks for the great explanation. smile.gif
No I am not an EE, i just had a basic education in circuit engineering, like 100 level courses. You can read this: http://www.alldatasheet.com/datasheet-pdf/pdf/398938/INTERSIL/ISL6366.html a lot of datasheets for PWMs are very informative. That one i linked has a VRM design guide in it lol, but that is Intersil and analog PWm maker, but the PWM is only a chip, the rest of the VRM should be the same for digital and analog.

Offset give you lower idle vcore, your load vcore will be the same or higher as you don't actually know what your VID is.

You need to set LLC man, you have to for Intel CPU OC, is it like a requirment. Some boards have LLC set on auto to a high level, here ithink if you set DVID LLC is engaged at a medium level.

Also you guys aren't measuring from the read points I see, please look below: THis is voltage comparison of CPU-z(Fake) vs digital multimeter(real), you can see extreme is actually raising your voltage while cpuz is reporting lower vcore. Please watch out for this, cpuz sucks for voltage readings, that is why GB put on voltage read points. Digital multimeters are so simple to use, they cost nothing($5-$10) and they are hundreds of times more accurate than software, in all cases on all boards. Depending on the LLC leve it can be okay to use CPUz or it might not be.

That sounds like just what I need, I'm gonna try this. Thanks.

You're right man, I just found an old multimeter and checked my vcore after setting LLC to Turbo and vcore to 1.140. In CPU-Z its showing 1.116 and in the multimeter its 1.135-8. Don't trust CPU-Z vcore! I have noticed that in CPU-Z the vcore voltage always drops when under load and then goes back up while idle.

Yah, I'm getting curious how accurate some of these software programs are. Guess I need to drag my bench meter out of the shop and set it up.
