Hello,

is one mobo better for extreme mem oc than the others?

Maximus
Hero
Formula?

Or are they all the same and it is only cpu/mem controller related?

Thx

CPU would be a 9900k and a 32GB RAM kit 4000/4133/4266

Any Board in the Lineup can manage what you try to archieve.

IF you want to go waay beyond the specs you have mentioned there are two boards that stand out:
The Maximus XI Extreme of course with E-ATX format. It is available.
The Maximus XI Apex with ATX format is the best RAM overclocker. It is not available everywhere.

Ah thanks - i forgot the Apex!

I remember that the old Apex boards should be better in ram oc.

Then i will take the Apex - thank you!

! Beware of the DIMM.2 SSD placement . It makes installing a NH-D15 with two fans tricky, but not impossible.
Maybe you will take some APEX cover plasic off (which takes one screw more than one would think).
Maybe you will also get rid of the VRM heatsink simply because the NH-D15 is heavy enough and the VRM-heatsink is really not needed (33 to 37C in idle).

My Z390-E does, if that means anything.

Thanks for your hint!
BTW: the DDR4-4000 CL17 Kit is a 4 sticks kit so it wont fit into the apex ^^

As you can see here:

My Hero + 9900KF + G.Skill DDR4-4000 CL17 appears with the new bios 1302 much more stable!

The first time i can run over 2 hours RealBench 2.56 stable at 4000Mhz CL17 !
With the old Bios max 3900Mhz CL17 worked.

Because of the problem with Apex DIMM2 & Noctua NH-D15S i go for the extreme mobo.
