    The problem is obtaining spare parts. One of the reasons bro @Mr. Fox sold his.

    FInally had time to install the 9900KS. Had to do a CMOS reset but after that BIOS recognized it. Unfortunately the factory set 5.0 Ghz (all cores) is just too much for this chassis so I had to downclock and reduce voltage. The lowest voltage I was able to get to is 1.070V during all core load or 4.6 Ghz!
    WOW!
    My 9900K would BSOD with this voltage even on 4.3 Ghz.
    For me 4.6 Ghz is way enough, it still easily beats even a 5.0 Ghz overclocked 8700K/8086K.

    After playing 2 hours of Rise of the Tomb Raider (this game is very sensitive for CPU voltage, if its not stable the game or the entire laptop crashes within a hour) I run some Cinebench and FireStrike runs.
    Please note that that the fans were on max however tests were made after the inside of the laptop was warmed up due to gaming. (if I run these tests right after boot the temps are about 3C lower).

    Cinebench R15
    After 1st run:

    during 6th run:

    Fire Strtike run:

    No throttling at all which I find cool considering that I only use the stock pew pew Clevo BIOS and only the single stock 330W adapter.
    I consider these temps acceptable considering that the CPU is using the stock IHS with STIM, if I were to delid it and install the copper IHS I have for 9th gen CPU, I could reduce the temp by another 5-8C.

    I do not have my results when I tested the 9900K but I can confirm that the 9900KS is a binned, much better quality chip which can work with lower voltage and thus give lower temps. With same all core 4.6 Ghz setting the stock 9900KS is about 10C cooler than my delidded 9900K (and about 16C cooler than a stock 9900K). With these settings this 9900KS runs around the same temp as my delidded 8700K did, however gives way much higher performance.

    tl;dr: If anyone wants to use a 9900 CPU in this chassis then among all of the variants (9900, 9900K, 9900KF, 9900KS), only go with the KS! This chassis can not handle its default settings however after downclocking and setting low voltage it can still give much higher performance than any other BGA laptop with acceptable temps.

    ps: Darn, just realized that RAMs were running on 2666 mhz instead of XMP 3000 mhz :/

    A machine a 1/3rd of the weight can keep up. I'd say it's a moderately powerful machine in the grand scheme of performance machines.

    Yea your right. The ole P570 is a Dinosaur now. X79 is old news ever since Ryzen increased our mainstream Processors core count.

    I’m starting to question if my current CPU actually is delidded. I feel like my temps should be better. Plus the black sealant around the IHS lid is pretty clean looking. Almost too clean looking.

    I may have to remove it and confirm.

    I can only run 4.8Ghz in BFV. And temps are in the low 90’s. I know the game is stressful. But still. If I run 5Ghz it will eventually throttle to 4.9Ghz and stick at 4.9Ghz with temps bouncing off 94-96C on some cores.

    “Previous owners said that he was told it was delidded” so I’m uncertain.

    I remember the good days when I first got in to X79 platform. I was pushing a i7 3820 to like right at 5Ghz or 4.95Ghz. The multiplier would only allow x44 hard limit on all cores, and I had to bump the BCLK for the additional overclock. Sandy Bridge would overclock pretty good though

    My chip was not the best, 4.3-4.4 was where I ran my 4930k.
