It is a much better board for high OCes. However the 4-pin power connector wont hurt your OC>
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
, 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.
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.
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.
