The AMD X670E chipset motherboard can support PCIe 5.0 channels for both graphics cards and M.2 SSDs However, recently some users have reported that the motherboard has unusual support board for PCIe 5.0 M.2 SSDs, causing the SSD transfer speed to become PCIe 1.0. , or the system cannot read and write normally, resulting in an unsuccessful restart.
On the ASUS ROG and MSI forums, users reported that they experienced distribution anomalies when using PCIe 5.0 M.2 SSDs such as the Micron Crucial T700 or T705. For example, user cx1088 may find that the CrystalDisk Info indicates that the SSD is using the PCIe 1.0 channel, but the CrystalDisk Mark 8.0 run score is using the PCIe 1.0 channel. PCIe 5.0.
Although cx1088 later discovered that the reason for this was that the benchmark software was not using a 1 GiB file size for testing. , but this did not explain why the motherboard It will automatically change the channel PCIe 5.0 to PCIe 1.0.
Same situation happened to ROG motherboard user Tomcoleman and MSI motherboard user rhonkar even if you change back to original mode, you can’t bring it back you have to reload the BIOIS to solve the problem.
Tomcoleman said that about 15 people around him happened to be in the same situation.
At this time, MSI has urgently provided a set of corrected BIOS, but some users still encounter the same problem, which has not been completely resolved by ASUS on actions provide no fix and can only ask users to send the motherboard to be repaired by.
Regarding Micron, foreign media Wccftech received a response after asking about the relevant issues The team can also reproduce this situation internally, and find if it is installed in the channel native PCIe 4.0, SSD chaos can be avoided. Unfortunately, this is a motherboard problem, not a defect on the SSD itself, and requires BIOS updates from each board manufacturer to resolve.
