    Please see new screenshots. Problem solved with bios update.
    Pay attention to lanes and link speeds. Now it is as it should be.
    Thanks for your help.

    Hello,
    First timer here as my journey begins, so I bought this laptop about a year ago, HP OMEN 17 , rtx 2070 / i7-9750h and I had absolutely no problems with it, untill a new BIOS upgrade recomended by HP came along. Untill this new version I was rocking BIOS F.22 Rev A and the cooling on this machine out of the box was amazing. The clock speeds on the i7 were at 4.2/4.3 Mhz (65 celsius) while the rtx 2070 was clocking at 1800 Mhz (55 celsius) that was on witcher 3 at 60 fps this was all done with a -200 undervolt on core and -140 undervolt on cache, while playing all games on default profile in OGH with fan speed on auto, playing it for about 6 months since all uk was on lockdown at the time. After the BIOS upgrade, with my undervolt of -250 mv on core and -120 mv on cache, the laptop is HOT. I mean really hot. Like 85/89 degrees on dota 2 and other games tested. On dota 2 for example I did a little experiment since I know the game is CPU demanding, and I lowered the frequency of the CPU in throttlestop so ii won`t go so hot, now it sits at 3.0 Mhz, and barely caps 120 fps, I raised the clock speeds to 4.5 Mhz in ts and I`ve seen no change in FPS. Same results with 3.0 or 3.9. SInce after the update my laptop can`t go beyond 3.9 Mhz no matter what I do, even if I use cinebench r20 or anyother program to test it. The power limit is also another problem I have, when I benchmark, if I`m on the default profile in OGH, it doesn`t pull enough watts to keep the clock speed of the cpu at 3.9Mhz, and it power throttles down to 3.2 Mhz. If I press the performance profile, it automatically stays at 3.9 mhz but gets really hot even with the fans at max speed. I did repaste, I cleaned all the dust from the machine, I even bought a cooling pad for my NVME SSD since one sensor in Hwmonitor showed me a temperature for the SSD of 95-97 degrees. Now I can`t play one single game without having to use the max fans, which are very loud. . I also tried overclocking my RTX 2070 and undervolting , it doesn`t effect it in games, just if I run a benchmark, it shows the 1.800 mhz clock speed, but in games it stays at 1.500mhz whle under load of 70/80%.
    In read dead redemption 2, before the bios upgrade, I had temps of 65-67 degrees while playing on 1080, 65-70 fps on ultra settings with fans on auto and default profile, now I am playing RDR2 on the same machine, repasted, cleaned, at 40 fps, doesn`t matter if I am on 3.9mhz or 2.9 mhz, while the temps spike up to 78-80 degrees.

    I am so sad that I did this bios upgrade, the laptop was working fine, this will be a lesson learned. All in all the laptop is good, too bad they had to mess arround with the BIOS and now the laptop is acting like 4 year old machine. Did anyone face similar problems after the BIOS updates, I went on HP support community and tried to get them to explain why I cannot rollback to the BIOS version I had when I purchased the machine, and they are clueless as every customer support in the U.K, even spoke on the phone with one of their operators and still nothing, he had no ideea what I was talking about. I am at a loss here, I have no ideea what to do, to make this machine work decent.

    Let's work backwards:
    I haven't had any issues with the BIOS updates all the way up to F35. The HP software on the other hand, specifically Omen Gaming Hub (now Gaming Center)...
    First of all, all the back BIOSs are available and you can try flashing back.
    I had your problems out of the box. It turned out they were all physical. You have different chips than mine (i9/2080) but the heatsink is the same according to the service manual. A repaste fixed all temp issues but it kept opening back up after a month. Turns out my heatsink was mismade and I fixed it with a shim. Can you use Core Temp or another per core temp monitor and tell us what your spread is like? If you have a big temp difference (10C+) that's a good indication the heatsink isn't sitting flat on the package.
    Do you have the H10 (the optane Intel stick)? That thing is nothing but problems. I swapped it out for an ADATA which also ran hot. Turns out the pads on the heatsink bracket are very difficult to make proper contact without some modifications. Removing the black plastic shield from the bottom screen also helps a cooling pad reach the SSDs.
    Are you stuck at 3.9GHz doing a single-core benchmark? It won't hit 4.5 on a multicore. Your system has to be running pretty clean after a reboot to achieve the max single core turbo. I'd try CPU-Z single thread benchmark, use Afterburner to keep an eye on CPU watts and frequency. This is also tell you what your power limits are, although HWinfo will tell you. Which leads to the next issue:
    The latest edition of OGH has a 28 sec timer on turbo, even in Performance mode. It never used to, mine could hit 90W continuous. There's a separate thread in this forum about disabling OmenCAP, as well as the underlying XTU service which is how OGH tweaks these parameters. This will require using a different utility like Throttlestop to have better control over your CPU. I never use anything other than Performance, but it's possible the default and comfort settings have changed the wattages as well which could explain your benchmark issues.
    I don't know what the max watts on the 2070 are, the 2080 is 150W. When it's running full tilt and CPU is using about 30W in a game, I see CPU temps in the 80s.
    Auto fan also never seems to hit 100%, or does so too slowly to be of use. I've switched to Notebook Fan Control which has a more abrupt but effective fan curve.
    The undervolting tolerance has definitely decreased with each update. However this is only good for a few degrees difference, I currently run at -.1 on the core only. The i9 is probably pickier and I don't think I got a great chip, but -.2 is really a lot on Coffee Lake and I'm not sure it was ever even doing what you thought it was.
    The fact that you ever had 55C just shows that you have the same heatsink--the 2080 idles around 40 and 300MHz for windows unless external monitors are plugged in or some accelerated app excites it. But it runs around 70-75C in games.

    This is a tricky machine--I had to repaste it three times to get permanent (1 yr now) results, including a rather half-assed adjustment with a shim. I suspect you are having a similar issue and that it's physical. The HP software is problematic, but problematic in terms of getting/maintaining max performance, not causing the temp issues. The bottom line is it's a balancing machine that can run the full gamut of the Intel chip, or the Nvidia at max, but not both at the same time requiring some CPU adjustments. Its thermal limit is thankfully right around the wattage that most games demand, but you can't bench the CPU and max Furmark at the same time. Each new iteration of the HP software seems more and more like it's crippling the machine to make thermal complaints go away rather than actually handling this reality as well as we can with Throttlestop. Oh, and a lot of them have defective heatsinks from the factory that doesn't sit flat on both chips.
    The good news is with lower wattage components, if you can get a solid paste job on it you will have better thermals than me. Let me gather some links for you regarding other people with the same issue.

    MY 2020 17t-cb100 i9-10885H and 2080 Super 150w are still on F.20. Thats the only bois HP recommends. There is a Optional update through Windows for "HP Firmware" but I figure thats not a good idea. Maybe thats the F.35. I did have to repaste three times to get a steady run but that could've been the TG Krioynaught to. The cooling solution on the HP doesn't seem to work well with TG paste. Im on Noctua HTN2 now and its almost 30 days strong with great temps. I also use Omen Gaming Hub to UV -0.095v. 75-80*c average on CPU and 55* on GPU.

    I wanted to try Kingpin KPx myself, unfortunately it's not available here in Italy, not even over Amazon in Europe I think. And Kryonaut is way too expensive over MX-4 to justify 1-2 °C less that I see in some indipendent tests.
    Early tesults by youtuber Bob Of All Trades (great channel in my opinion) gives Kingpin KPx the 1st spot, but he did have reservations on the long term stability of teh paste and promised to check back in 6-12 months of usage.
    Can you post a screenshot of CPU temps and frequencies with Hdwinfo and Trottlestop CPU under load? I'm curious about the 5 degree difference over MX-4, seems too good to be true for a normal non conductive paste.

    Well I repasted with MX-4 (and the temperatures got down more than I expected.

    Both on idle (CPU 36°C, ambient 21°C) and while gaming (core 0-1 go to max 81-83°C, core 5-6 only to 74-78°C).
    That is with latest BIOS, Trottlestop SpeedShift set to 0, turbo limits to 39 (3900 mHz) to CPU cores and undervolt (-125 mV CPU core, -100.6 CPU cache, -49,8 Intel GPU both core and slice).
    GPU temp never go over over 50-54°C under gaming, GPU running a little bit over 1600 under load and underclocked in MSI Afterburner to max voltage 0.835 V.
    Also I use NotebboFanControl with a better (more agressive) setup than the original one from latest HP Bios (as in my fans start funning more rpm sooner and bnot when the CPU is already past 80°C). They are not too loud on this gaming notebook and the better cooling will surely help the paste and the hw components in the long run.

    Overall I'm satisfied with this paste's results, but I am courious about Kryonaut as people say they can get about 2-3 °C better cooling on average. But I also hear that the pate doesn't last as long as MX-4 (my last application of MX-4 on another gaming notebook was doing quite good after almost 3 years!). For Kryonaut I read a lot about it losing effectivness after 6-12 months and needing a repaste.

    But data is scrarse about this so I hope some of you here on the forum like @Burrick can keep us updated on Kryonaut or Kingpin KPx over time. Would some of you be intersted in posting screenshots of a particular CPU or GPU test (free trial versions of programs) so we all do the same and compare results?

    Guys I have been testing with trottlestop (9.2) and and I have a question about power limitations on our Omen 17 cb0 (2019). I have the latest bios (F.35) and I experience strange power behaveour under full CPU cores load under both Cinebench and TS Bench.

    When I start the test, all 6 cores (12 threds) are at 3900 mhz as I set them in TS. CPU temps are stable 72-78 °C on all cores....BUT.....after 19 to 20 seconds the PL1 Core power limit appears and the cores go down to 3300-3400 mhz (and the temps go down to 60-68 °C).

    Obviously there is no problem with my temps or power brick (CPU goes easily to 3900 mhz in the first 20 seconds.). Is this power limit directed by the BIOS itself? For what reason since there is no problem with temp or power supply

    It doesn't change even if I change the PL1 or PL2 settings in TPL section of trottlestop, nor if I change undervolting of the CPU (normally at -0.125V).
    Does anyone else have this problem?
    Does anyone else have a different BIOS version and can test this?

    Check that OGH isn't interfering with TS (OGH turns on by itself the UV feature, and sets a value for both Core and Cache when it updates through the MS Store), turn off the feature and disable fast boot in W10. check from time to time when OGH updates, and turn it off again if it happens.
