Hello, I'm back with my question. "What is the revision of the motherboard Rev. 2.00 or Rev. 2.03? The product exists in two revisions, for the same denomination: A) AsRock Motherboard B450M Pro4 2.0, Rev.2.0 B) AsRock Motherboard B450M Pro4 2.0, Rev.2.3 Is the product sold by Galaxus Rev.2.0 or Rev.2.3? Because the CPU support is different for each Revision: A) AsRock B450M Pro4 Motherboard 2.0, Rev.2.0 = Supports Socket AMD AM4 Ryzen™ 2000, 3000 and 5000 Series Desktop Processors. B) AsRock B450M Pro4 2.0, Rev.2.3 Motherboard = Supports Socket AMD AM4 Ryzen™ 2000, 3000, 4000 G-Series, 5000 and 5000 G-Series Desktop Processors. I happen to have AMD Ryzen type 4000G (Renoir-Zen2) and 5000G (Cezanne-Zen3). Thanks a lot! PS The motherboard model is below the name B450M in small (2.00 or 2.03)
