    Default Asrock 970 Extreme4 strange throttling

    Firstly, I'm sorry for my english, I'm Spanish

    This board have got throttling, and this throttling is very strange. I have got two examples:

    I Start windows and run IntelBurnTest in stress level maxium 10 times 1.2 hours and nothing happens, no sign of throttling

    I Start Windows and whait 25 minutes, I Start IntelBurnTest in stress level maxium: extreme throttling all the time

    Haven't got throttling in the CPU whit stress level in Very Hight, No throttling whit stress level in Custom 6144, only throttling when I use the Maxium memory that it have got.

    The temps are very good, 26c mainboard 44c CPUInt 32c Package.

    I think that the problem is because the bios need a new update

    I wait for a answer Thank you!

    Write more about your system configuration, and hope somebody can help.

    Your hardware specification looks good; But now, at first step, you should make isolation between hardware and software defects.
    For doing so, simply, prepare a diagnostic tool which is self-bootable either on a usb flash or an optical disk (cd/dvd).
    For example, see this project (has both cd and flash version):
    https://www.ultimatebootcd.com/
    After you made relaxed about the hardware, you start to investigate your Windows OS, its configuration (e.g. power options), suspicious interfering software (e.g. antivirus), and etc.
    My guess is that one of your hardware components doesn't wake up properly after sleep.

    UBCD is useless, this is for X86 machines, and my SO is X64. The power options are configured in balanced mode. My antivirus had béen desactivated during the stress test. And I'm not use any sleep configuration too. I dont' know what is the origin of the problem. I know about another PC with the same motherboard, processor and memories that it have the same problems. Is for that I think the problem origin is for the bios.

    Throttling problems with AMD boards when using high power usage processors like an 8350 are usually caused by the CPU voltage regulators (VRMs) over heating.

    Your board's VRM design is a 4 + 1 Power Phase Design, which is not very strong. ASRock includes this in your board's processor compatibility list for the FX 8350:

    For cooling the CPU and its surrounding components, please install a CPU cooler with a top-down blowing design.

    This really means air movement over the VRM heat sink, to the left of the CPU socket, is needed to keep it cool.

    It is strange that you do not get throttling when you run the CPU stress test right after booting the PC, but only after waiting 25 minutes. But using all your memory in IBT is the highest stress level possible. It may take longer for the VRMs to get hot, and after 25 minutes the cooling in your PC case cannot cool the VRMs enough.

    How much memory are you using, and what CPU cooler are you using?

    Memtest86+ (included in UBCD) tests total of memory (not restricted to 4GB). Its test also is a good proof of CPU/Chipset sanity. So, most incompatible hardware is shown in this test, many computers show errors when they are cool, while some show errors when they become warm (and many machines, always). Use it for at least two pass and see.
    The only thing which is not tested by Memtest86 is IO problems, specifically problems caused by your hard disk(s). That CD has various manufacturer utilities for diagnosing hard disks.
    Other CPU diagnostic tools are run on any x86/x64 systems and do not need the system to be x86 only! Because AMD64 architecture includes all 32bit as well as old 16bit CPU codes.

    Bios is most effective in computer start (before OS startup) and hardware detection. A bad bios should usually have one of these symptoms: memory incompatibility, lack of hardware detection, or power saving issues.
    Heating/Cooling investigation (as "parsec" said) is in hardware phase and should be considered first. After that, you can open windows task manager in conjunction with your test to see if other process is using the CPU. A burn-in test should take above 98% of CPU as usual.
