    Thank you good people, I'll try ones again...
    This is not my first time doing OC, but this particular board is stubborn as hell...

    Oh, I see the problem...
    In second screenshot you have TURBO POWER LIMIT 500W and
    CORE CURRENT LIMIT 300A...

    I simply cannot make the change of those values!!!
    What ever I do in 3d BIOS the remain the same.
    In M.I.T. I cannot change the value too. It says AUTO all the time!
    Please help with what I'm missing in this BIOS.

    Same in all versions from F10 to F12t...

    Ibach, leave the Turbo configuration for the last part. First of all you must ensure you can work with 125Mhz on the BCLK, and you won't need Turbo multipliers for that.

    Disable Turbo, save and restart. That should disable all the "features", so the power limit and current limit won't work at all. Set the Host Clock Frequency to 100.00Mhz, and then set the Gear Ratio to 1.25x. Before saving, check the RAM and set it to 13.33x, that should give you 1666Mhz.

    Save and exit. Now you have 4500Mhz. Once you got this working you should start playing with Turbo multipliers, memory, timings, etc.

    True.
    Works at 4500 :) 1.47 v (will try to lower it as possible though EDITED: stable at 1.4v might try lower...)
    What about overvoltage and overcurent protection?
    should I simply max it out or set it to minimum stable values?
    And, again, how did you change TURBO POWER LIMIT?!

    Hm... And I really have no clue about XMP settings of the memory...
    Mine should work on 2133, but when BCLK set to 125 it only can boot and be stable on 2000 (16x 9/11/10/28 how do i set 10r 1t on this board?! hate gigabyte the BIOS i mean) with XMP disabled.
    I also cannot save any of my settings in BIOS (F11 option does not seem to be present) so it is a pain setting all those things after clearing CMOS... EDIT: Got it, reflashed BIOS, it showed up in save and exit last 2 options, no F11 shortcut.

    Great, I'm glad you found it.

    Now, if you set Turbo Enabled, you should have the power limit enabled automatically at the same time. I set 500W, and 300A, to avoid throttling. But I'm almost sure that you can keep them in AUTO and it should work, at least for 4750Mhz. If you see any kind of throttling while at full load you should set those values to avoid it.

    On the memory side, those timings seem to be Samsung based ICs. Anyway, they should work 2333Mhz without a problem. Remember that not every CPU can handle those clocks, but you could give it a try once you've found your max CPU clock. You'll need to use a higher VTT and IMC voltage, also.

    Go to MIT - Advanced Memory Settings, and set the XMP to Profile1. It will set the XMP profile but the clocks of the memory will go to 2666Mhz, so select the 18.66x multiplier instead. On RAM Timing Selectable choose "Quick", it will use the timings you set on the first module to the rest. Then, on Channel A Timing Settings set 10-12-12-30 1T, and you should be good to go. If it's not stable, 10-13-13-30 will most likely do it, or play with the voltages.

    I've only got this screenshot, it's old, but it should serve as a guide:



    Please, post your results. I'm trying to hit 4625Mhz, but it's asking too much volts. Maybe it's a bad overclocker, or maybe you find something I'm missing.

    tried lowering cpu pll voltage to 1.65v? it might help you get stable with less cpu voltage

    if its locking up at idle its either using too little voltage and you need to add more offset/dvid or level higher llc,for memory make sure you set dram voltage between 1.5-1.6v and maybe a touch of qpi/vtt,anywhere from 1.05v stock to 1.1v(max safe limit is 1.2v) but you shouldnt need that much

    I'm fully stable (2hs Linx with 16GB RAM usage) at 4500Mhz 1.39V, 2333Mhz 1.65V. CPU PLL is set at 1.81V, I'll try a lower value. VTT and IMC are both at 1.2V, didn't try lower. I'm not having idle lock ups anymore. If I set 4625Mhz 1.47V, it gives me a BSOD, 0x9C, which is memory/IMC related (even if I set 1666 or 2000Mhz), so, I believe it's the L3.

    I can't believe that I need 1.48V, or even more, for a miserable 4625Mhz OC. That is almost 0.1V higher than 4500/1.39 for just 125Mhz... :(

    I've lowered the CPU PLL to 1.65V, the VTT and IMC to 1.15V and it failed within an hour. Now I'm back to 1.2V on the VTT and it looks to be fine. With 1.2V on the IMC but 1.15V on VTT it also failed. Everything as it was befor (4500@1.4 2333@1.66). Once I had it stable with low PLL I'll try 4625Mhz.

    Maybe I need more VTT for 4625Mhz. Is tat possible? Can I give it more than 1.2V? Asus boards give up to 1.4V if is set to AUTO, but I've read that it isn't safe.

    About the performance 24/7...
    As I use AutoCAD at work a lot, I've found that my performance at higher CPU clocks than 4.3GH is actually not much better, even if I get it to 4.65 (which i was able to do thanks to all of you) there is no much improvement in the workflow.
    BUT, pushing RAM to 2666 really made a great difference.
    I've made a ramdrive for AutoCAD cashing of all its s*hit and it fly. Not only that it works great at only 4.3GH but it also does not use any cash on my SSD which is fast, but not comparable with RAM, not to mention it hates too much read/write operations in general).
    These settings also made it bearable to remain in the same room with my PC considering all the noise it was making when on 4500GH+ ;)...
    Drawing in AutoCAD for some reason does not ask for clocks that high, what it really needs is responsiveness (the stupid program uses mostly only one core and that is its biggest problem).
    Hand is still much faster than PC of any kind, brain too, so if PC does not response in milliseconds it all goes to hell.
    To achieve that I've found that TURBO is what I need. All enabled and set to Auto will closer responsiveness to drafter needs.
    KILL - disable C1E, and all the other C states, Thermal monitor and EIST. Those things are killing the performance I need, with files that are not too big I'm ok at4.3GH and very fast memory.
    Big files are the problem for CPU, and there is slight performance improvement when at +4.5GH.

    I'm now interested in quiet cooling for my system so I can actually work in the same room with my PC.
    What I'm thinking of is building custom water-peliter based cooling system that will cool my CPU and all the other components at 20C all the time at all the stress it can take and with moving parts (those stupid noisy fans) out of my box, placed in the other room or the window with only cool water flowing to my PC.
    When I do that I'll post back.
