System-Specific DDR4 Kit

This 64 GB kit contains four 16 GB DDR4-2400 registered ECC DIMMs built for the ASUS WS C422 PRO/SE motherboard. Each module runs at 1.2 V with CL17 timings and a 2Rx8 organisation. The 288-pin design fits only platforms that accept registered memory.

Registered ECC Upgrade

The modules replace standard unbuffered DIMMs in workstations that require error correction and signal buffering. The jump is worth it when the workload demands data integrity across 256 GB maximum capacity with RDIMMs or 512 GB with LRDIMMs. Mixing registered and load-reduced modules is not supported.

DDR4-2400 Interface Limits

The DDR4-2400 interface caps transfer rates at 19200 MB/s per module and the memory controller will clock down depending on the installed processor. Registered DIMMs add one cycle of latency versus unbuffered parts. The platform provides eight sockets but does not allow RDIMM and LRDIMM mixing.

Questions about this item

Will these 288-pin DDR4 DIMMs fit the eight memory sockets on my ASUS WS C422 PRO/SE motherboard?

Yes, the kit provides four 16 GB registered ECC modules that install in any of the board's eight DDR4 slots, leaving four sockets free for future expansion up to 256 GB with RDIMMs or 512 GB with LRDIMMs.

What is the correct installation order for the four sticks so the system recognises all 64 GB?

Populate the slots following the motherboard's quad-channel sequence — typically slots A1, B1, C1, D1 first — and ensure each module clicks fully into the 288-pin socket; the most common mistake is seating only one side of the DIMM.

If a module fails years from now, can I replace just that one 16 GB stick?

The kit carries a limited lifetime warranty from Computer Memory Solutions; a single failed 16 GB RDIMM can be swapped for an identical CL17 2400 MHz part without replacing the full set.
