X670e Taichi Carrara Bios 3.10 problems

Hi Asrock,
recently I updated my X670e Taichi to the latest BIOS (3.01) and I encountered a severe regression for my DDR5 ram kit.
I am using a Ryzen 7950x and a Corsair 96GB KIT (CMH96GX5M2B6000C30) that always worked like wonders with XMP 6000 AGGRESSIVE profile (wich gives me a NICE performance bump) until the 3.10 bios.

Firts thing I noticed is that with the latest bios there is a sort of "double boot": first there is memory training (code 15), then the system reboots and goes again in memory training , while with the previous bioses it would usually boot to windows. After this second boot, I usually have a 00 code after a minute or so of memory training. And the system fails to boot if using XMP 6000 Aggressive profile.
The funny thing is that if I press the reset button when the 00 code appears, the system reboots, goes into memory training and then it boots to Windows normally and the system is rock stable (mem-tested overnight).
However I am not confident in using this BIOS because when a memery training will occur again (usually in a couple of weeks or so if I am not changing settings) I will again get the 00 code at boot.
This behaviour never happened to me with previous Bioses with the same settings...

Finally, please Asrock, fix that damn bug that prevents the Waterpump fan Header from working during Memory training, making processors overheat and force the system to shut down! I had to completely change fan headers and settings with my Arctic Liquid Frezer III if I want to use individual controls on CPU fan, waterpump and VRM fan.
