While X299 Dark supports 32GB memory sticks I am still unable to use them to get full 128 GB on X299 Dark. Those interested in details of my experience can find it in this thread https://forums.evga.com/128GB-of-memory-on-X299-Dark-with-i910900X-m3019996.aspx

No, G.SKILL DC modules are essentially two DIMMs on one PCB, requiring special receipe to work. They are not supported on EVGA boards.

Would these be supported https://www.gskill.com/product/165/326/1571734065/F4-3200C16Q-128GVK-Overview , please?

Any issues with using G.Skill, e.g. Model F4-3600C17Q-32GVK or Model F4-4000C18Q-32GTZKW given that they're not listed on G.Skill's QVL? This would be for the Z390 FTW variant.

I'm having odd huge performance drop when trying to use 32GB sticks in all 4 slots on X299 Dark. Details can be found here https://forums.evga.com/Low-Memory-Benchmark-Woes-m3040897.aspx
 
I've opened ticket for it and EVGA's Jose is already looking at it but I would appreciate if other senior EVGA techs could please look at it too.

TiN_EESupported 32GB memory list:

No mention of the X299 Micro ATX 2. ?

While the CPU Compatibility lists have been updated to include 109??X CPUs, none of the X299 boards Memory Compatibility lists have been updated to include any 32GB DIMMs.
I am sitting here with a shiny, new X299 Micro ATX2 motherboard and a shiny, new i9-10920X CPU.  I have not yet purchased RAM for this system.  Seems like there must have been some testing before making this splashy announcement.  Share, please!

Im also curious which 32 Gb sticks will work on the Z390 Dark, I would like to upgrade to 64 Gb from 16 Gb. Keep the good info on coming.

I never tested X299 Micro ATX , but I'd expect latest BIOSes for all X299/Z390 to support 32GB density DRAM modules, EXCEPT G.SKILL DC modules.
Feel free to contact EVGA CS for exact details. Particular kit may not work best, especially when overclocking with XMP, but it should work.

Would this Kit work on the Dark X299 ?

no takers on my question ?
