Asus Maximus XII Hero ram QVL misleading, wrong...

Level 7
so I managed to grab this maximus xii hero for my 10900k...

as I checked the ram qvl (ofc I want 4800mhz bdie ram 😄 ) on the official site I found something interesting (I will attach the screenshost also):

g.skill F4-4800C19D-16GTRS as supported... hmmm interesting coz its should be F4-4800C18D-16GTRS

anyway I did a big google search and nope no results for the C19D. ahh ok its just a misstype I thought coz the F4-4800C18D-16GTRS is fully supported by maximus xii apex also stated on gskill site for apex. my idea was hero=apex z490=z490 so, no probs I bought the rams 😄

the first boot with my new 4800mhz rams went fine .., enter the bios xmp and this was funny xmp profile shows 4807mhz .,. and from that part I knew I gonna have a problem with it. reboot bla bla enter windows.. and after 1sec lockup/freez.

the rams are only usable on 4400mhz.. tested all the bios versions (the betas also) but no luck.. contacted the hungarian asus support (pff better not its a mistakwe 😄 )

so I would like to ask is gonna be a support for this gskill rams ? if apex can why not on hero ?

thanks 🙂


Yep. tested everything. my main problem is not that I cant achieve 4800mhz on hero (but Iam 10000% sure one bios update can fix this) .. but to let asus know that the qvl they posted is totaly messed up and ofc to correct it

Have you placed your RAMs correctly on slots A2 and B2 and not A1 and B1 ?

Did you try the XMP 2 mode (the XMP 2 respect default XMP timings, while the XMP 1 optimise XMP timings) ?

Your CPU IMC isn’t up to the task. The QVL basically is stating that if you have a golden CPU with a golden IMC, you could hit 4800.

There’s little benefit to memory at that speed. I’d return your memory and save a dollar by getting something closer to 4000. Even 4000 was tough for some of the previous gen 9900K to support through their IMC.

If I remember correctly with the last gen, there were diminishing returns beyond 3,800.*

or just run at a lower frequency and tighten the timings manually.

now its running on 4400mhz .. with stock cas... dont have time right now to play with it also dont care much now 😄 . anyway the qvl is a big mess but the maximus xii hero official site is down right now I hope they will correct the list

thanks @all for the replies 🙂
