    When in the bios after just loading Optimized defaults, look at the column in the center for vcore. This value should be the VID (default vcore) for me my cpu was 1.115. Now as you change cpu multi vcore will change when set to auto or using DVID following the SVID in the cpu.

    Edit - When overclocking the cpu the only thing you should need to change is vcore. I would suggest changing Load line calibration under 3d power to turbo then set vcore to the value you see at the middle column. As you increase cpu multi slowly increase vcore as needed.

    For memory set memory to rated speed then set Dram timing selectable to quick and set the base timings for your memory example 11 11 11 28 1T. 1T being command rate which is a little further down in the same screen.

    Leave everything thing else on auto.

    That's actually quite a difference. I understand it right then.
    So basically whatever I see in the middle column is a default value? (assuming I am running with optimized defaults setting)

    I was just interested why does the middle column value change at all after playing around with multiplier.


    Btw I tried some Prime95 and with (presumably) default vcore and just slightly raised multiplier (only 37 so far, slowly testing) I am seeing temperatures around 80-86C across the cores. Is that bad? Idle temperatures seem to be more or less 50C. I expected a bit less tbh....

    Hmm your cpu should auto overclock to 39x or atleast mine did from optimized defaults and 35x being set in bios. If you are on the stock intel cooler those temps sound correct. These things run hot, I would suggest getting after market cooler or look into a watercooling kit. I forgot to say to set ddr voltage to rated votlage for your memory.

    Max core temp on these is 105c so you wanna keep core temps to around 85c for 24/7 use.

    Well I bought Coolermaster 212 EVO and swapped the fan for my Noctua P12 I had in the "old" PC, so cooling should be good.
    The temperatures still seem a bit high, but Prime95 really pushes the damn thing.

    In fact the idle temps seem to be more like 45 (I didn't leave it alone long enough before, it seems), with some of the power saving options enabled. Priming again I see pretty much the same results: 80-85. At least it seems stable at 38x.

    I got one more question on top of the curiosity about "normal" values, which are still a mystery.

    When underclocking, or say trying to lower the temperatures in general, which one shall I lower first? Vcore or PLL? Or maybe, which one has likely higher effect on stability? I hit a stock vcore limit at exactly 4GHz it seems, so I might as well just try to lower the volts a little.

    Yes normal values are exactly that normal or what is stock voltage for stock clocks.

    leave pll set to auto. to lower temps at idle you can try using dvid which will lower vcore at idle and then raise vcore at load.

    So I did a bit more testing, and despite being somewhat unlucky with my CPU I really like IB so far.
    I couldn't get anything above x40 to work properly (x41 still booted, 42 was freezing the bios after a second or two) so I started to tweak down the voltage.
    I could boot into windows at 1.000V but Prime95 would apparently crash after some time (I woke up in the middle of the night and it was just gone; PC was still running though), so I was upping vcore a bit few times. Currently testing 1.015V, hopefully I won't have to go higher.

    I wonder what kind of miracle piece did this guy have. 4.4GHz on default voltage and stock speed at 0.9V!

    There's a lot of variability in IB cpu's, just as there is in SB cpu's. Some are good over/under clockers with low volts, most aren't. Neither one of my 3770K cpu's are particularly good as far a low vcore, although x44 OC is pretty easy on stock volts with the UD5H on at least one of my rigs, if I remember correctly. I keep both rigs around x45 now. Prime 95 max vcore is between 1.26-1.272, others can go lower, some higher. Pretty much luck of the draw cpu wise.
    Of course temperatures scale with voltages MOL, and the lowest stable vcore will give the lowest temps.

    Guess I just have to experiment more.

    Btw anyone ever had problems with F_USB30 double port? I connected a 3.5" bay with two USB 3.0 connectors to it an only one works. I hope my board is not faulty because RMA would take a month. I'm left with one functional port either way :/

    Just got a new 3770k cpu in today and is installed. This chip is a Malay chip vs old chip was a costa rica chip. I believe the costa rica chips are better overclockers and temp then the malay chips. I will post of benchmarks when i have some.
