Hi everyone! I make this post to ask : how to get a ryzen 7 5700X3D to post on a MSI B450 Gaming pro carbon AC?
The thing is I am upgrading from a ryzen 5 2600 to a ryzen 7 5700X3D but I can’t get the mother board to POST. The system posts properly with the ryzen 5 and I already cleared the CMOS, and the BIOS is up to date.
Likely a bios update you need to apply. At one point the B450s weren’t going to support Zen 3. AMD reversed course later, but that likely means that a bios update had to come along in order to add the support.
Lots of motherboards, even new ones, still ship with old-ass bios.
Also, remember that memory-training is a thing now – don’t assume that 10 seconds of a black screen means it won’t post. Easily wait a minute or more - board could just be in memory-training to get the best speeds.
Some boards even have a light indicating this is occurring!
