The Ryzen 9 5950X processor is compatible with the MSI PRO B550M-P GEN3 motherboard as it uses the AM4 socket supported by this motherboard. The air cooling used for the Ryzen 7 5700X might not be sufficient to effectively cool the Ryzen 9 5950X as the Ryzen 9 5950X has a higher TDP of 105W. It might be advisable to use a more powerful cooling system to ensure optimal performance and longevity.

Thank you very much for letting us know. We will be happy to pass this on internally to the relevant department and hope that this will be checked promptly.
