X670E Motherboard Issues: PCIe 5.0 SSDs Slow Down to Gen 1

Owners of X670E-based motherboards are facing a serious problem: their PCIe 5.0 SSDs, which are supposed to demonstrate high speeds, are suddenly reducing performance to ancient levels. Gen 1. This failure affects not only individual board models, but also products from well-known manufacturers such as Asus и MSI.

In the early stages of using Gen 5 SSDs, such as Crucial T700 и T705, everything worked as expected, but over time, users began to notice serious failures in operation: performance decreased, systems began to freeze, failures occurred when loading Windows, especially in cases where an SSD and a video card connected via PCIe 5.0 slots were used simultaneously.

The problem goes beyond the usual troubles that can accompany new technologies such as PCIe 5.0For many early adopters of X670E boards, the move to Gen 5 SSDs was a key decision factor, and now they are faced with unacceptable limitations.

Asus recommends that users contact support from SSD manufacturers such as Crucialto deal with the problem. In turn, Crucial conducted its own investigation and determined that the root of the problem lies with the motherboards themselves. In tests on several X670E boards, they reproduced the speed drop and said that users should contact motherboard manufacturers to issue BIOS updates that will fix the problem.

Crucial has released a statement indicating that the issue appears to be occurring when connecting Gen 5 SSD to the corresponding slot on the motherboard. As a temporary solution, it is recommended to use Gen 4 mode for SSD, which will avoid performance degradation.

Company MSI already released a BIOS version update 1.0c, which has reportedly helped some users, but the problem persists for others. For now, the temporary solution remains to use SSDs and graphics cards in Gen 4 mode, which, of course, is not a satisfactory option for those who purchased the equipment for the benefits Gen 5.
