AMD may have announced that the Ryzen 5000 series would support X470 and B450 motherboards from January 2021, but ASUS has other ideas. Multiple motherboard manufacturers, including ASUS, have already released updated BIOSes for 500 series chipsets, but the company has dropped X470 motherboards from future plans.
ASUS is yet to officially confirm this, but it is letting consumers know privately that this is the case. Apparently, the engineering department at ASUS has confirmed this, rather than a sales representative or customer service advisor. You can read the ensuing Reddit thread here, which has, unsurprisingly, received plenty of attention from AMD fans.
In May, AMD confirmed that it would ‘enable our motherboard partners with the code to support…AMD B450 and X470 motherboards’, giving some hope for Ryzen 5000 support. However, AMD has not instructed its partners to support B450 and X470 motherboards, so ASUS has decided against doing so. Seeing as ASUS is yet to confirm this publicly, then we would not be surprised if other motherboard manufacturers follow suit in dropping support for the B450 and X470 chipsets.
