    Each CPU is different, no all CPU's can do -130mV undervolt, looks like your is only stable with -55mV, there is not much magic to be done, its the silicon lottery.

    Repasting might help you.

    What @senso says is accurate. The ballpark average for 9750H is probably about -125mV (just a guess based on observations, not a scientific study,) which means many will be capable of something less.

    An undervolt is also arbitrary. There is nothing magical about the undervolt setting number, only the end results matter. What is your load voltage? This can also vary by product/firmware, so -55mV on system A might be the same as -100mV on system B. (For example, the product of 500 - 100 is not the same as 450 - 100, even though you are deducting 100 in both calculations.) I think a fairly average load voltage for 9750H is around 1.125-1.175V, which will vary based on load temps. A CPU running at higher temps needs more voltage, and most turdbooks run way too hot no matter what you do. Some manufacturers do not adhere to reference firmware specifications. Some improve upon them, some make them worse, and others follow direction precisely, even to a point of fault, because they lack the ability to think on their own and don't care about the outcome.

    And, 89°C is better than average for turdbook load temps. The errors mean the core or cache voltage is too low. You can try setting the core voltage lower than cache voltage and see if that helps. Leave the cache at -55mV and try more than that on core, see if the temps, benchmark scores and TS errors improve. The goal here is to achieve full performance and keep the temperatures under control. So, don't get overly caught up in the idea that there is anything special about the undervolt value. If your CPU runs right and the temps are good, the value of the undervolt being applied as a custom setting is totally irrelevant.

    Nice job. Temps are decent. And, your actual voltage (not the offset amount) is right about where it should be, too.

    I'm regularly seeing Power Limit Exceeded, Ring Power Limit Exceeded, IA: Package Level RAPL/PBM PL2, PL3, IA: Max Turbo Limit and IA: Turbo Attenuation (MCT) all being hit shortly after starting up the machine. I know this isn't an HWInfo forum, but are these anything related to undervolt or overclock being too aggressive. Sorry, still learning with all this stuff.

    I just wanted to share a ThrottleStop success story. I was recently helping a user on the TechPowerUp forum with his new 10th Gen Core i7-10710U.
    https://www.msi.com/Content-creation/Prestige-15-A10X/Overview

    https://ark.intel.com/content/www/u...0710u-processor-12m-cache-up-to-4-70-ghz.html

    The Intel spec shows a CPU with a 15 Watt TDP rating but he was having no problem pushing this CPU up over 50 Watts. :eek:
    He started hitting the wall at this point. The ThrottleStop log file was showing VRTEMP throttling. Not too surprising considering how far beyond TDP he was running. We should call this kind of performance, "beast mode". Nice to see that the 10th Gen has some potential in a thin and light package.

    Hello, it seems I now have my integrated voltage regulator VR faults disabled and have no way of enabling it back on my i7-4720HQ. It was changed in XTU, but I turned it back on before it asked for a restart of my p650se laptop. After the restart, integrated voltage regulator VR faults disappeared and integrated voltage regulator VR effficiency mode was left disabled. I can turn efficiency mode back on but not VR faults. Throttlestop shows VR faults as disabled with an unchecked box. Thought adding a check would enable it back, but still reports disabled.

    Thought maybe it's set in the bios and did a reset to defaults, however that didn't enable it back. Tried a system restore, that didn't work. So I guess it's just stuck in a disabled state forever now, correct?

    Update: Nevermind... should have did a cmos reset (removed battery) before bothering anyone.

    It'll be jnterestiin what performance a 9750H or 10750H(?) Will get in a 15W package.
    On another note, was that CPU undervolted? My older 8250U at -140mV still guzzled 40W under Prime85

    Anyways I'm getting the i5-10210U in a few days. Am hoping for unlocked FED159A0 power limits and capable VRMs. Not expecting desktop class performance from the (presumable) single heatpipe, but I'll see how far I can take it. The Thinkpad E14 series is new and I'm not sure if they've managed to lock down enough things. Anything you want to see with TS and Comet Lake?

    Definitely! With 6 cores hitting 50W, you need all the help you can get.

    Thanks for your offer to help. ThrottleStop appears to be working wonderful with 10th Gen Comet Lake. Post lots of pics so other users realize this. XTU is probably not going to be supporting the 10th Gen U series so ThrottleStop might be the only option for users. :cool:

    TS is working great on my MSI Prestige 14 with the i7-10710U and my Dell XPS 7390 2-in-1 with the i7-1065g7. Just trying to figure out which of these laptops I'll keep though...
