    Hi all! Pls help me i have problem

    2 months ago I successfully overclock my i5 6500 to 4.4 (1.35v) .A today I wanted to optimize the voltage (had blue screens) and lowered voltage. After that my PC is not turned on and the BIOS default settings restored. After this I would like to introduce the best value BCLK (135.00) and voltage (1.25v) And when switching windows 10 that I saw standing on the default BCLK (100.00) Thereafter, I downloaded the new BIOS. Here this here “191” and the problem persists(((

    Sorry for my bad English,i just russian guy))

    I couldn’t OC neither with this bios neither with the older one. After changing frequencies, my I5 6600 non K always shows 3,3GHz in cpuz, HWMonitor, HWiNFO.

    It’s like it’s capped @ 3300 mhz and doesnt go beyond that, even if you tweak it differently.

    Any one has the same problem?

      I think intel has done something at the processor level because I’m experiencing the same issue with my Gigabyte Z170 Gaming k3 and new bios FC2. You can turn up the clock as high as you want, but it wont hold after reboot no matter voltage or how low or high clock frequency. CPU is locked at 3,7 ghz (i3 6100). Mr der8auer says hes still able to overclock his cpus no problem. But I don’t think hes gotten any cpus from the new batch.

        just updated my i5-6400 on msi z-170 pro on 4.4ghz because i overclocked my memory before to high and bios was reset in default.
        had similiar issues like the ones described here.
        solution was:

        1) get the corresponding bios flash file on usb stick (mine was because i have the z-170 pro from msi)
        2) turn off the computer
        3) go in bios and start the flash update dialog
        4) IMPORTANT: dont go in the bios, just start your operating system, check with gpu-z if your cpu is still in normal mode (for my it was 3.3ghz dynamic boost mode)
        5) turn off the computer again
        6) now go in bios and put the settings der8auer describes for your model IMPORTANT: check again your memory settings and the ratio, for some reasons it sometimes changes to wrong parameters when you put one parameter, especially the memory
        7) put the core voltage like the 8auer recommends. for me it was 1.25)
        8) now save your settings and reboot. if the pc isnt booting the first time, it will not work

        hope this helps

        P.S.: if nothing helps, you put the clear cmos jumper on your board, and you will have your old standard bios, which is the best to have before flashing the here available ones

  • All hello, help please, do not accelerate the i7 6400 t, engineering sample, put two available BIOS for the motherboard, with one does not start at all, the other does not disperse what to do ??? Sorry for my english … help please !!!))

    i Destroyed my CPU with that BIOS. I am not completely new to PCing, but its been a while. The First Try was ok, i reached about 4GHz stable but there were Sound and other issues due to RAM OCing i think (setups wont run etc). I flashed back to original firmware and a few days later back to the flashed Version. Well then i must had made some mistakes and there went my CPU. All i did was Vcore 1.22 and BCLK 125. But i sure must have had any other stupid option. So now i am going for some really expensive upgrade, but it was really my stupidy. Just want to remember you have to do OCing with patience and system. Not like a Berserker
