Thanks so much all. I have solved the problem. Insert another DIMM and get improved the PCIe Gen5 IO performance. At the begining, we are using single DIMM in system, the IO is limitted. Now the 2nd DIMM is inserted, the issue is solved.
Thanks a million. The configuration x4x4x4x4 is used to assign dedicated 4lanes to individual SSD. In theory, 4 SSDs must show us the performance more than 50GB/s in sequential reading test. But it is not true.
I have also tried the "ROG CROSSHAIR X670E GENE" from ASUS, of course, CPU is still...
Now I am using a B650E motherboard with 7600X CPU to measure the PCIe Gen5 devices. Unfortunately, I find the PCIe Gen5 slot can not get up to full speed. It seems the PCIe Gen5 x16 slot has only x8 capability.
Using B650E and X670E MB with 7600X CPU to test PCIe Gen5 performance. The...
