Unfortunately I don't remember the original rev, but I was able to successfully upgrade the board to Rev P5.00.
Yes, the mainboard is mATX.
No. The mainboard supports PCI-E 3.0.
Hello, It is the BIOS version that is decisive, the motherboard will be compatible with the processors mentioned as long as the BIOS is updated to version P5.00 or later. This applies regardless of the Revision. Here is the link to the different BIOS versions available for download: https://www.asrock.com/mb/AMD/B450M%20Pro4%20R2.0/index.asp#BIOS As indicated by other customers on your previous question, the card is delivered in Rev. 2.0, with BIOS P4.60. You should therefore plan to update it to use the Renoir and Cezanne CPUs.
Mb revision is 2.0, current bios is P4.60. Younger bios is still beta.
