Z890 APEX - recommended CUDIMM?

I'm going to purchase CUDIMM RAM for my APEX. I do know the Asus list with certified memory. However, given my very bad experience with  problematic DDR5 on Z690/Z790, I wonder is there any first hand CUDIMM brand recommendation from actual APEX user.

1 (1).pngFor what it matters, I got meanwhile G.SKILL  F5-8800C4255H24GX2 for my APEX.  It runs like butter, booting with XMP @ 8800 without delay. Goes with XMP settings up to 9200 @ 42-55-55-140, would probably reach 9400 with increased voltage. Seems to be good stuff.

  • Motherboard: ROG Maximus Apex 
  • BIOS Version: 1302 with latest ME firmware
    Processor: Intel Ultra 7 265k
    Memory: G Skill  F5-8800C4255H24G @38-53-53-55 1.55v
  • AI OC: ON
  • DIMM FLEX: OFF
  • DIMM FIT: ON
  • TWEAK: Mode 2

 After some fine tuning by trial & error, and found that this GSkill 8800 RAM is running 100% stable and error free at 8800 38-53-53-53-55 at 1.55v. 

With BIOS 13.02 latency is down to 71.8 ns latency.   

 Disabling DIMM FLEX is giving me consistently slighty better/lower latency readings. (not sure, maybe random results)
