Asrock B550m Pro4 - Hyper M.2 slot

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi All,

I've recently installed a WD Black SN7100 on this motherboard and for some reason, it's only showing on the WD Dashboard Tool that it's only connected to a Gen 3 x4 PCIe slot, even if it's a PCIe 4.0 SSD. I'm only getting read speeds of up to 1300mbps and read speeds of up to 2300mbps.

Why is this the case when the MoBo says it should support PCIe Gen 4? Any help would be appreciated.
