    Maximus X Formula 1401 Bios Unstable OC

    Just reporting in, The new 1401 bios has made my system completely unstable at anything but stock volts and clocks, No clue what you guys at Asus are doing but this is not a good bios.

    I reflashed with the previous bios and the system is rock solid, Performed my suite of tests and all is good, I flashed again with the new 1401 and it's completely unstable so it's definitely the bios that is messing something up.

    EDIT 1

    Ok it appears even with downgrading the bios it's no longer stable either at anything other than stock volts and clocks, I noticed during the flash of 1401 the ME was also updated which I've never seen before and it cannot be undone by simply flashing back to an earlier bios, This seems to have had a negative impact on overclocking, I'm guessing this has to do with more Meltdown and Spectre mitigations, which ironically has also mitigated your most expensive Z370 boards overclocking potential.

    I can confirm this as I have an MSI Z370 board on hand and my overclock works perfectly, So yeah, Nice one Asus, You messed up the ability to overclock on your most expensive Z370 board, Well done.

    EDIT 2

    So I put the 8700K in the MSI board and it runs happily at 5GHz with 1.34v rock solid just like the Maximus did pre-flash, I put it back in the Maximus X Formula and after the latest bios flash which also updated the ME etc... it now requires 1.42v to be stable compared to the 1.34v in the MSI board, That's quite a big difference Asus, No clue what you did in the latest bios but it's really not good especially as this board costs nearly £400 and 1 of your "engineers" has royally messed something up.

    Sort it out please.

    GSKILL F4-4000C18D-16GTZR There is a compliance issue with ram. Overclocking capability is down. Also, in the raid setup, if you disable csm from bios, the system crashes. While fast boot is active.matherboar apex x.
