Windows 10: ASUS motherboard RAM timings problem

Ok, just updated the BIOS on my ASUS Pro WS X570-ACE motherboard, from 1302 to 2301.
Obviously, the computer is working, but I had previously set the RAM timings to manufacturer's specs, but can't seem to do that... this time.

Motherboard support page: Pro WS X570-ACE FAQ | Motherboards | ASUS Global

My RAM: F4-3200C14D-16GTZKW-G.SKILL International Enterprise Co., Ltd.

Here's the current status... the problem ofc is translating the XMP naming scheme to the BIOS nbaming scheme... for the DRAM timings.













The problem is, that w/e I try to manually set my RAM timings, like before the BIOS update, everything craps out. No display, can't get in the BIOS. Have to pull the CMOS battery to reset... and to do that I have to pull the vid card.

Here's how I had the timings set before the BIOS Update...

Asus Z370 Maximus X Motherboards

The 9th gen processors that are currently available is still the P0 stepping and will eventually be replaced with the new R0 stepping processors.

Here are the screenshots I took from Gigabyte's website




Gigabyte redacted the new R0 processors from the list a day later.

 

Choice of memory and motherboard... a bit stuck...

No one who got some suggestions on this one, huh?

I've found out that the Asus M3A78-T needs to be flashed, so then that motherboard is excluded from my list. Which motherboard and memory should I then go for? Any suggestions?

 

ASUS Z370 ROG Maximus X Hero Motherboard - Drivers

Thanks for the info.
Just out of curiosity, I am wondering if the ASUS EZ Update utility provided you with a newer driver that "was or was not" already listed on the ASUS download page for your motherboard ?

Has there ever been any known cases where something such as ASUS EZ Update utility provides the user with updated drivers that are not listed on the website ?
