Frequently Asked Questions

What is the difference between M393A8G40MB2-CVFS and M393A8G40MB2-CVFSM?

Both are Samsung 64GB DDR4-2933 ECC RDIMM 2Rx4 modules from the same family. CVFS and CVFSM are different production revision suffixes — they are functionally equivalent with the same specifications.

Is the M393A8G40MB2-CVFS compatible with Intel Xeon Cascade Lake processors?

Yes, it is compatible with Intel Xeon Scalable Cascade Lake server platforms supporting DDR4-2933 ECC RDIMM. Verify your specific server's QVL before ordering.

What does 2Rx4 mean?

2Rx4 (Dual Rank x4) means the module has two ranks of memory chips, each using x4-wide chips — providing high capacity with good memory bandwidth for enterprise server workloads.
