    I have had this laptop for a couple of days, it's mostly for work.
    My work applications are mostly single threaded so was hoping the 4,3ghz single core boost clock would help with those tasks and i could even do a little overclock to 4,5ghz.

    The problem is that it won't turbo boost on a single core. To go into a higher boost clock, the cpu has to put a couple of cores into a C6 state, but that just doesn't happen with this laptop.
    Sometimes you can turn that on in the bios but that is not the case either.
    I've even tried to do a clean install, but 0% C6 state and the boost clock doesn't go over 4,1ghz. Dit gigabyte disable this without an ability to turn it on? (this also increases the battery life).

    I put BITS on a external usb drive and booted from that. To check if C6 state is disabled in windows or the bios.

    Requesting the C states, it only returns C0, C2 and C3. No C6. This means Aorus disabled the C6 state in the bios without an option to turn it on again.

    This link shows the extra battery life http://www.legitreviews.com/what-en...es-do-on-the-core-i7-4770k-haswell-cpu_2217/3

    The C6 is also needed to boost the clock for a single cpu, which doesn't work. With the cpu on stock settings it doesn't go above 4,1ghz while it is supposed to go to 4,3ghz on a single threaded load.

    YES you could remap the key through AORUS Fusion (assign different key)

    maybe try re-paste the thermal grease to see if it works

    Hi,

    This has nothing to do with repasing the thermal grease, it is disabled by the motherboard. I can't enable a feature on a motherboard by putting different thermal paste on it.

    Besides, this should help with thermals, as the lower power state cores would use less power.

    Aorus Fusion allows you to remap keys and/or map macros to a key. My V7 has a UK keyboard and when set to US international, the keys can be mapped according to the US layout. Not sure whether setting it to the German version, in your case, allows you to remap whilst having the actual, German, layout.

    there're two reason for unreachable clock:

    1. Power is not enough
    2. Temperature is too high

    from our experience on X5, the power is definitely enough, however the temperature may get high under heavy load
    when the time we tried overclocking on X5, the clock speed could keep around 4.1~4.3Ghz if the thermal grease is evenly pasted
    The test is conducted under the latest BIOS & EC

    P.S. here's the screenshot of CPU SKU

    I just updated my system BIOS on the X5 V8 from FB03 to FB04 and my CPU speed is now limiting to 2.8GHz for no discernible reason - it's not power or thermally limited; it just tops out at 2.8GHz even if both minimum and maximum CPU speed is set to 100% in my Windows Power Profile. Intel XTU shows all cores set to 4.3GHz just like before the BIOS update but it won't go above 2.8GHz in actual functioning.

    I noticed I can override the limitation with ThrottleStop utility and get full speed, but only with the AC Adapter plugged in. If I unplug, back to 2.8GHz even with ThrottleStop running.
    Has anyone else experienced anything else like this? Could this be a messed up effort in the newer BIOS to limit CPU speed while running on battery?

    Does anyone have an installer for the FB03 BIOS? I'd really like to try downgrading in hopes that it goes back to normal.

    If not, I did create a backup of the original BIOS but it looks like I need help flashing it:
    I did use the AFUWINx64 EXE included with the FB04 BIOS installer to dump my FB03 BIOS to a file BEFORE I undated to FB04 (thinking I could use this same utility to undo the upgrade if there was something I didn't like) but it won't flash the dumped file.
    I'm trying to use this command: afuwinx64 stockFB03.rom /p
    but I get this output: "18 - Error: Secure Flash Rom Verify fail."

    Note: The stockFB03.rom file I dumped is only 8MB whereas the download X5V810.B04 rom file is 16MB. I'm assuming the size difference is because my backup is only the "main BIOS" whereas the download contains additional data, so I'm using the /p switch to "program main BIOS."

    AFUWINx64 does appear to support switches to override secure flash policy to capsule, and/or override secure flash policy to recovery. Do I need to use one of these options to flash my backup? That's what I'd like to try next but I hate "experimenting" when it comes to BIOS on laptops because it's so hard or even impossible to recover if you screw something up.

    Any help would be appreciated; thanks!

    The problem is with the turbo boost itself, the C6 state is disabled by your bios. I can't get 4,3ghz stock, even when the laptop is cold and only 1 thread is used.

    Why don't you try to get that 4,3ghz, without overclocking the cpu. It won't happen because you disabled a core feature of the cpu.

    The other problem is that i want to overclock it only for running 1 cpu, because the C6 state is disabled, it won't ever do that. I have to set the whole overclock to 4 cpu's.

    Usually you have a setting in the bios to turn C6 on, because it can sometimes help with overclocking. But there is no setting for this on the aorus x5.

    The gigabyte 15X does have the C6 state enabled

    I've had this problem too, i disabled the commander software, because that does weird things with a strange overclock settings. After that i overclocked in throttlestop, but only the multipliers, ive underclocked the voltage slightly and kept the turbo short/long boost power the same.
    I've noticed when the boost power is changed, it reverts to 2,8ghz.

    The overclock setting of the commander software is really weird, it sets it at 4,3ghz with the gaming preset but that also puts the fan way more aggressive. Then there is the normal preset, but this one clocks the cpu to 2,8ghz with a more silent fan. Both not what i want.

    Well here's the thing: This all worked FINE with the FB03 BIOS. I could do up to 4.4GHz OC on all cores without needing to involve ThrottleStop. I could even do 4.7GHz single-core. The CPU did everything it was spec'd to do without issue. I settled on 4.3GHz all-core for thermal reasons, but now I'm limited to 2.8GHz ALL THE TIME.

    I've also disabled the Commander software btw and use only Intel XTU for overclocking, but I can find no setting that gets me past 2.8GHz with the new BIOS. If I limit the cores to less than 28x, say 27x, I get 2.7GHz, but anything more than 28x and the multipliers won't go above 28. That CANNOT really be the intended behavior, an i7-8850H that's locked to only 2.8GHz? That's stupid.

    I fully intend to find a way to downgrade the BIOS back to FB03, as I had none of these issues before.
    Does anyone have a copy of FPTW that's compatible with the HM370 chipset? My research indicates this would allow me to flash the 8MB backup I created before the BIOS upgrade.
    Please link or PM me if you have a copy of FPTW that'll work with this machine; thanks!
