    Awesome! I'd like to repaste it but I have no clue how to do it, I've seen videos but nothing specific to this laptop. Kinda afraid of messing something up! Do you have any tips for a beginner, or maybe know of a guide?

    Always a reason... From the

    NBR review of Omen X laptop with unlocked i7-7820HK

    In our testing, we were unable to get a stable overclock at any multiplier between 37x and 40x. Performance was shaky in both the Omen Center benchmark and Cinebench with some multipliers giving lower scores and hitting lower clock speeds, and one setting (38x CPU multiplier, +0.505 V) crashed the system and forced a full reboot. Given the high thermal output of the CPU at its base multiplier (more on this in the Stress Test below), we opted not to push the silicon any further.

    Yes I noticed that huge downgrade in performance too for better battery life 344 mins Optimus prime profile.

    I think I know what they are on about regarding stability between 37 and 40x. The Omen Center appears to not hold onto those settings upon rebooting. Although it says it does, after rebooting it goes back to 35x.
    38x +0.505V is a monstrous amount of voltage.

    I've got mine repasted with Kryonaut, CPU Core and Cache at -135mV, iGPU at -65mV, multiplier set to x39 with all cores active and it's working great. All the settings were done in throttlestop. Handles it like a champ.
    I think I can go way lower with this. Tested it at x40 with -150mV and it breezed thru 4 games of Battlegrounds, then I tried a -165mV and it crashed. Still needs more testing to get the most out of it, I'm just not very patient.

    Current settings (x39, -135mV) it doesn't go past 86C in gaming loads which is pretty good. Stable and no throttling.

    BTW, what's the best way to revert Throttlestop changes when crashing occurs? It won't open in safe mode, I had to delete the settings.ini to get it back to default values and start over.
    I heard some people put it on a 5min delay on task scheduler but I can't find that option.

    I use another TS profile for startup when I test out new overclock settings. Aka pc boot up as usual with stable voltage and settings. Take a look here regarding delay of startup task.

    Hello everyone! Glad to see a group discussing the Omen X laptop performance, I too own this fantastic machine (since December) and recently did a repaste with Noctua NT-H1. Running benchmarks with a -.125mv undervolt runs in the 70s, but gaming on Vermintide 2 with a 36x multiplier results in a crappy 86c on the CPU. The GTX 1080 stays around 71c though. I do want to try a repaste one more time this weekend to ensure i have the best paste job on the 7820hk. Ill take pictures this time if anyone is interested.

    If you want to repaste might as well switch to a better paste. NT-H1 is pretty good but Kryonaut is slightly better when it comes to regular paste.
    You can also go the Liquid-Metal route, I bet that, with this cooling system, you would get some pretty radical temps. It does come with some safety concerns though.

    I took some pictures when I opened mine up:

    I got Micron modules for the 32GB 2400Mhz RAM

    Similar to the Alienware 17 R4, you also need to remove the rear "trunk" in order to get the heatsink out easily. Not similar to the AW 17 R4, this thing is much easier to repaste.or clean

    To remove the heatsink the CPU fan has to be removed on its own

    Heatsink assembly off (don't forget to remove any M.2 SSDs before pulling on the heatsink, as these have a plate under them for added cooling)

    Close up of the vacum chamber. Any sugestions on how to prepare and clean up this surface a bit?

    This is mid thermal pad replacement. Swapped them out for Arctic pads. I didn't run into any issues but figured might as well. Very important to check every single chip for proper contact when doing this.

    I was hoping for a better drop in temps but it didn't happen. It really needs an undervolt to keep it under check. GPU temps are great though.

    If you have any questions fire away

    HI. Few questions if you don't mind.
    1. What is weight of this laptop?(it seems its weight is not as shown on official web)
    2. Does it work for 5 hours on light use?
    3. Can you recommend it for hard 3D content creation? Not gaming
    Thank you

    And sorry for newbie question, but will i have better color accuracy if i purchase 4K panel but downscale it to 1080p?
    If i am correct this will even save some battery?
    I don't need 120Hz. I need very good color reproduction

    Almost 5Kg, plus the charger, pretty hefty.

    I don’t know, haven’t used it for very long on battery power. Check notebookcheck.com, they have a nice review where they test and talk about the battery.

    I think it’s more than well equiped for that. But if you can wait I’d go for something with a coffee lake CPU as I think the added cores will be beneficial for 3D work.

    If color accuracy is what you’re looking for then yes, the 4K panel is better. I don’t get why you would downscale though, might as well use the added resolution!
