Users running the high-end AMD X670E motherboards with Gen5 SSDs are facing various issues, mainly with the devices being limited to Gen1 speeds.
AMD's AM5 platform was the first full-fledged PCIe Gen5 platform, offering Gen5 capabilities for both GPUs and SSDs. The first iteration of AM5 motherboards, the X670E and B650E series, gave users both GPU and SSD Gen5 support while the Non-E motherboards offered optional support with Gen5 SSDs. The upcoming X870E and X870 platforms will further extend Gen5 capabilities.
However, it looks like those who invested in the AMD X670E platforms are facing several issues with the primary one being their Gen5 SSDs being limited to Gen1 speeds. This issue is affecting many customers who are running a Gen5 SSD on their X670E motherboard and it's not just Gen5 speeds being limited. When both the first Gen5 SSD slot and the PCIe Gen5 slot are populated, the system experiences random crashes, with several users unable to boot into Windows.
The issues have been occurring on various Gen5 SSDs such as the Crucial T700 and T705 SSD which are some of the fastest Gen5 drives on the market right now. Users report that the Gen5 SSDs ran flawlessly at the start but later, their systems started to hang, crash & fail to boot into Windows. It would take several restarts before the system would eventually work but upon troubleshooting, it was discovered that the Gen5 SSDs were running at Gen1 speeds which hampers the overall speed and performance.
The ASUS and MSI motherboard forums show several users running X670E motherboards and a graphics card in the first slot experiencing similar issues. It was discovered by some users that reverting to Gen4 speeds or using a Gen4 drive would resolve the issue and the systems
