Just thought Id update. Got an r5 3600 and b450 board about 2.5 years ago. Gigabyte b450. Been running the older, faster, official "AMD Sata Controller" drivers vs the "recommended" ones from MS with zero issue for two years. From AM3 platform. Offers a significant performance improvement over the MS ones. No downsides. Specific version 188.8.131.526 but there are a few you can find that will work fine.
