I reached out to MSI last week to see when and if it would be updating its X370 chipset motherboards to support Precision Boost 2, that we found to work so good on our water cooled Ryzen 2700X, and it tells us that the support is already in all its X370 EFI. That seems like it happened fairly quickly, but I guess that is a good thing.



The X370 BIOS on the website [already] supports AMD Precision Boost 2.
