MSI launches new B550M-P and B550M-B motherboards that extend the life of the AMD AM4 socket
The longevity of the platforms amd is well known by users, and to display a button, with the platform AM4 reaching the 10 years of life and receiving full processor updates 2026. So that users not only have options to add CPUs to their current equipment, manufacturers are also adding more motherboards with this socket to their catalog. He already did it ASUS and now he also follows in his footsteps MSI which has added two new plates with B550 chipset.
MSI launches the new PRO B550M-P and B550M-B to extend the life of the AM4 socket
These two new models are the MSI PRO B550M-P and the MSI PRO B550M-Btwo models microATX that they have socket AM4 and therefore support for DDR4 memory. Perhaps this compatibility with DDR4 memory is so necessary at this time that the decision to amd extending this platform has surely helped (and made happy) many users who are not willing to pay the high and exaggerated amounts who are currently asking for the DDR5 memory.

Economical motherboards with DDR4 and options to expand or repair AM4 equipment
As for the two added models, they seem to be more oriented to home users and small offices. The PRO B550M-P has four slots for memory DDR4 with up to 128GB maximum, and is accompanied by 2 slots for discs M.2 SSD with connectivity PCIe 4.0. The PRO B550M-B has two DDR4 slots and support for 64GB maximum, although it maintains the two slots for M.2 PCIe 4.0 SSD drives whenever a AMD Ryzen CPU with AM4 socket that admits them.

An ideal option not only to build your new PC with a lower cost, but also offers the possibility of repair equipment where the motherboard has been damaged. Whatever your option, one of the two will surely meet your objective in case you have a Home PC with AM4 socketor are looking to build a new PC for basic functions that do not require state-of-the-art hardware.

We leave you the complete configuration of both models.
