Was hoping to receive the new memory today (Trident Z Neo 32GB 3600MHz CL18) but the couriers are in no hurry. Can't say the same about me, because this week I must sort things out and decide what to keep and what to return from the stuff I bought.
During the last few days I read as much as I could from this thread - not all of it, but I went through all ~120 pages written since Vermeer launched, and to my surprise discovered that it wasn't smooth sailing for quite a few users who reported problems very similar to mine. Here's some snippets: (sorry for not using the quote function, but I had saved everything of interest in a text file).
tried 3333, 3267, 3200, 3133. Nothing works, it feels like mobo is not even attempting to work with those, everything just locks up.
The soft power and reset buttons stop working, not responding to long holds as well.
Set 3000 again and it booted like it was nothing. (

guys stop flashing 7.03 with Zen3 its dangerous.Its not stable with 4 dimms even with 2133 goes black screen,fans spins and reset/power buttons are not working.It need hard power off and clear CMOS to get training memory again. (
@Senniha)
Did you made any changes to the PBO section ? i.e PPT/EDC/TDC values ? when mine is set to auto it won't boot. (
@wizardwiz)
All good but windows boot stucks before starting, anyway I can see the round icon rotating, just for 20 second. Then at reboot ask me to recover for not good shut down.
System start correctly in safe mode! (

Last one, right after the release of 7.10:
1st major bug: Setting IF on auto, fcks up booting in windows, gets to recovery console, but everything is messed up. Setting it manually on 1:1 (1900, in my case), works as it should. (

I also learned a lot about various BIOS versions incorrectly setting the secondary ram timings and also about (God forbid!) crossflashing with the X470TC firmware. Anyway, since the new ram didn't arrive today and I'm gonna be quite busy for the rest of the week, I started tinkering with the system as if the new ram was there. And although I had a (mental) list of things to try, I went straight to the most radical item, crossflashing. And it actually works, so my board is now a X470 Taichi with P5.10 BIOS. Dunno if I'm the first to report it, but I confirm that the 5900X works with this BIOS (there was much talk about Vermeer not working with previous X470TC BIOSes when crossflashed to the X370).
Problems? Yeah, still, but nothing of the magnitude I experienced with 7.10. Twice I wasn't able to enter UEFI setup, system just froze with the Asrock logo and "press F2 to enter" still displayed. This seems to be solved for good after a CMOS reset and now I can enter setup at will.
The CPU temperature is a bit on the high side, often hitting 90 degrees C under Prime95. For now I'll assume this is because I completely run out of MX-4 (ordered a new tube, should arrive together with the RAM) so I had to use a very dubious and old "Halzniye HY510".
Also, adding the other 2 DIMMs and setting the frequency to 3200 (XMP) and entering the correct secondary timings resulted in BSOD-ing even at 1.4 volts, so for now I'm at 3000MHz @1.35V. And while we're at this, how can I find out the proper values for ALL of the secondary timings? The BIOS (XMP information) reveals little, and Thaiphoon burner even less, compared to the plethora of settings available under "advanced dram timings" or how it's called...
