    Hello everyone.
    I recently got my Schenker XMG U507(clevo p751dm2-g) with the 6700K and a GTX 1070.

    I had some temperature issues when it comes to the CPU, but found a thread on this forum that solved them by putting an undervolt of -150mV to the CPU.

    On my laptop there is a software pre-installed, where you can adjust these cpu setting, but I decided to install XTU because I saw that it is more advanced than the factory tool.

    The only thing I changed in XTU is the core voltage offset to -157mV (currently) and somehow the System is adjusting the "Turbo boost power max" value automatically.

    If I restart the system it is automatically set to 53.XXXW. Due to this, the cpu gets clocked to 3100Mhz when stress testing.

    I have to manually set this value to 95W again, every time I restart the system.

    I checked the Bios and the P1/P2 settings are disabled there.

    Shall I try to just set this value hard to 95w from bios?

    Thanks in advance.

    Could I ask what are your fan settings and temps when running at 4Ghz after the undervolt? Also which screen are you using? (sorry I'm just really interested in this machine)

    Regarding your problem I don't know much but I have heard that the stock Clevo Bios is very faulty. I don't know if it's possible by any means but maybe it will help if you get the Prema BIOS - it's a modified BIOS created for CLEVO machines that solves many problems and enables maximum performance. I just don't know if it's possible to get it after you buy a machine.

    Hope you solve the issue! Could I PM you for some questions regarding this laptop? :3

    For Gaming I mostly use the "custom" fan setting, starting fans at 65 and stopping them by 50. Max Fan on 80%. I now have a undervolt at -157mV. The VID at load is about 1.16 - 1.2V. The Temperature at Battlefield 1 with ULTRA Preset and Full HD + VSync enabled (60FPS) is 65-79C for the CPU(at around 55-80% load) and 70-80Cfor the GPU.

    Without the Undervolt and fan settings at "auto", I reached 100C CPU Temp in Battlefield after about 15mins of gameplay. It reached so far, that I had thermal throttle and bluescreen.

    The undervolt saved me around 15-20C for the CPU, which is great!

    Right now idleing at 4184.63Mhz (99.63x42) at 1.1570VID and 32C CPU with fan settings set to "auto"

    No problem, just PM me.

    Found something out:
    I removed XTU and "Hotkey"(CC) and made shure, that the XTU service is killed and all files are gone.
    After I reset the BIOS back to the defaults, the Power Limit is back at 95W.

    I enabned the overclocking options in the bios, but I cannot change the "core voltage offset" to a negative value in the bios...

    Does anybody have an advice..

    that's one of my gripes that I told @Meaker@Sager about in the stock BIOS

    If you look at the tooltip next to the voltage offset on the right, it says you can set a value from -500mV to +500mV, but if you type a minus sign, it doesn't register......

    Even if you do it through CCC and set it to a negative value, if you check in the BIOS it shows as a positive value :rolleyes:

    In the Prema BIOS, you cannot type a negative value in the field as well but underneath it, there is a + or - sign you can select from. I think Clevo just forgot that part

    Pretty reassuring that I'm not the only one haveing this problem. Thank you.

    But for me now, the problem stays, that as soon as I undervolt in CCC and restart the system, the CCC changes the Power Limit 1 / 2 to (random?) low values. After the restart now, the values have been set to

    PL1: 29.3W
    PL2: 53.125W

    Are the Power Limits at the same value for you, if you restart the system ?
    Its annoying to change them everytime as soon as I restart..

    :(

    Here's what I would do......

    Reset BIOS to defaults......

    Downloads the latest Throttle Stop and set your options like this.....

    TPL are the power limits, maximize them like me, it won't hurt, the system will only draw the power it needs

    But change the multipliers and voltage offset to what suits your CPU. The power limits and turbo power limits shouled be maxed out

    @Mr. Fox , please suggest anything that you would change in these settings if any

    Thank you very much ! I reset the bios to factory defaults and disabled XTU in the Services in Windows.
    I Pretty much just changed the voltage offset and TPL limit and kept defaults on the other values.
    Working perfectly.

    But there is still the question why the CCC/ XTU change the PL1 and PL2 limit to such low values... Is it because I have the 230W PSU ? Maybe @Meaker@Sager knows why ?

    Thanks

    Its something I have raised but for now you will have to set it via software.

    And regarding my problem with the power limits ? that the CCC automatically sets them to low values?
    Thanks in advance
