    You have updated the Mobo BIOS right ? I remember some youtuber had a hell of a time trying to get 9900Ks to work properly only to find at the very end that he needed to update the Mobo BIOS. Here is that link although his problem was different
    Are you also saying that the 9900K on the same motherboard with same setting can fly higher then 127W but with the same settings on same motherboard, the 9900KS is restricted to TDP ?

    This video from Gamers Nexusshows how different motherboard vendors is handling the EPS powers differently. May be you need to change your Mobo to Gigabyte ? May be MSI is following restrictions like ASUS.
    You may need to reach out to MSI suppport via Facebook etc. I have reached out to them before and they are usually quite responsive.

    Yeah could be bios. I'm on Apex with latest bios, I'm not sure if it handles the processor different. As I always ran earlier 1801 with 8086K

    Hi guys just wondering your thoughts on cheap z390 motherboards vs high end for 9900k?

    I'm using low end Asus Tuf Z390 gaming matx as wanted smaller board/case. Seems to run perfect and testing 5ghz all core 1.3volts seemed stable with temps hitting max 70degrees.

    Many comments online saying 9900k needs better vrm boards but I dont feel like my current board is causing any issues and I'm not aiming for biggest overclock that is possible. Would you bother getting a better motherboard?

    Ran 9900KS on MSI itx board. OC on 52-53x 1.4Vcore. Fan over the vrm section. That's an average $300 board new

    Just keep your shit running cool. An easy OC now is 5Ghz 1.3v

    Good Lord, that looks really serious. Explains the 1.4 volt. :thumbup:

    For what it matters, I have my 9700K running (stable enough for gaming) at 5 GHz at 1.3 volt with AIO cooling. After an hour or so running Prime 95, one of the cores gives up. My AIO cannot handle temperatures above 1.3 volt.
