    Overclocking 9900KS on Maximus XI Code/Hero - Results?

    Has anyone started overclocking the 9900KS on the Maximus XI Code/Hero?

    Are there any results yet?

    I'm about to pick up my 9900KS and am not sure if I should Stick with Maximus XI line (i have an 8700k on a Maximus X Hero now) or switch to Gigabyte Aorus Master (or even the Aorus Xtreme)

    I keep reading the bios and ram overclocking is better on the asus boards, but the CPU Overclocking is better on the Gigabyte. I'm conflicted...

    Any suggestions would be appreciated

    The 9900KS is just a cherrypicked 9900K. Just like the 8086K was a cherypicked 8700K. My 9900K runs very happily at 5GHz on all cores just like a KS. It's all about the silicone lottery!

    EDIT: My 9900K might even go higher than 5GHz I just haven't tried it yet lol.

    Mike, this is totally off topic, but were you a Street Fighter or Chess player ?

    Asus X hero Z-370 wifi owner + 9900 ks just installed on latest bios 2103 and everything seems fine

    5 ghz all core
    load line level 6
    cache @ 4.7 ghz
    vcore = 1.28 v manual
    ram @ 16 gb 4000 mhz cl-17
    all power limits / ia dc load lines maxed and ia ac dc load line = 0.01

    hard ware info 64 open and core temo logging

    seems my 9900 ks on z 370 x hero needs

    1.28 v load line= 6 manual vcore to pass prime 95 versionm 26.6 1344k test and 1.26 v for asus real bench

    this is with 4000 mhz ram tuned tight and cache @ 4.7 ghz

    adia 64 memory benchmnark said 59,987 k read , 60,4123 write 53,231 copy latency = 40.1 ns !

    my 8700k did 5 ghz @ 1.28 v and 5.,1 ghz @ 1.355v no avx offset in prime 95 26.6 small ffts .

    switching out 8700k for 9900 ks droped my memory latency from 42 ns down to 40.2 ns thats 2 points ! same exact settings

    so long story short my 9900 ks and 8700k both need 1.28v for 5 ghz lol

    should i keep it or go for better 1.28 v for 5 ghz all core ?

    i heard z-370 needs 0.030 - 0.050 v more then z-390 to be stable is this true ?
