Your CPU is not defective, you are just getting a lower score in R20 than you should. This indicates something maybe not enabled in the BIOS. PBO, Precision Boost Overdrive, is not normally enabled on motherboards by default. Mine was set to Auto which seemed to never use it. You would most likely get scores that are closer to what everyone else gets if you enable it in the BIOS. My 3900X scored lower in R20 bench tests as well compared to what others were getting and it was my PBO settings. By default A-XMP, memory settings, and PBO seem to be not enabled(turned on) by default. Being that you are building your own system you will find that somethings you need to enable or change to get the best performance.

Need to keep temps up to 62 - 65c range and of course have PBO enabled, fast memory also helps.

I am fiddling with X570 Taichi and I cannot get an OC at 4.3 or 1.30v with R3900x ,, I also have ASUS ROG Strix X570-E Gaming and with this I get 4.3 at 1.25v with the calibration at minimum
Is anyone working with this board ?? I can't achieve something stable
