Anyone tried the X470 Taichi 5.10 BIOS with a 2700X installed?

Hello

 

Has anyone tried using a Ryzen 7 2700X with an X470 Taichi on the latest 5.10 BIOS from ASRock? I am wondering what the experience is like and if any of the issues with RAM speed are sorted out  from dropping support for even older CPUs (currently I've tried the 2700X in my board and any speed above 2133 refuses to POST and goes back to 2133 after 2 boot cycles. Disabling CSM for Resizable BAR Support on my 5900X also means the system refuses to POST with the 5900X installed and I have to use the 2700X instead if I want to use ReBAR. If this doesn't fix any of the issues should I downgrade to 3.50 (last BIOS before full support for Pinnacle, Raven and Summit Ridge CPUs was dropped) so my CPU has full support for 3200 speed DDR4 again ? (For context I just picked up a cheap used X570 Taichi with all the accessories and a 2TB WD Black SN850X on Black Friday for a deal too that I want to use instead of my X470 board and current 1TB drive. Theres also the Wifi 6 improved RAM speeds, USB ports and the fact that I can either use my 2700X, some spare RAM, a 500GB NVMe as another PC with my GTX 1070 or I can sell the mobo, CPU and RAM as a set which means it will need to work properly with that spare RAM).

The problem is not the motherboard, it's the memory controller in the CPU.

Zen+ has a pretty bad memory controller.

I could DEFINITELY run 2666 speed and 3200 speed and POST before I updated my BIOS to support Ryzen 5000 series. I know it was temperamental at times because I had crashes and unstable behaviour in Windows which is why over the years I dialled the speed back to 2933 and 2666 and after that it ran rock solid and didn't have any memory issues until I upgraded to the 5900X last year. Any speed above 2133 doesn't post at all and 2133 cripples performance especially on Ryzen. And it doesn't sound like you have a Taichi and are running that particular BIOS anyway. Wanted to know if I could run a higher speed on the latest BIOS before going through the downgrade process as that can be dangerous if things go wrong. I'd prefer not to brick my first computer motherboard.
