16GB DDR5 ECC RDIMM for ASRock WRX90

This 16GB DDR5 4800 ECC Registered DIMM is built for the ASRock WRX90 WS EVO motherboard. It delivers 4800 MT/s transfer rates with CL40 latency at 1.1V. The 1Rx8 single-rank layout uses major OEM chips from Samsung, Micron or Hynix. It fits standard 288-pin DDR5 server slots.

Compatibility limits for this module

The module suits administrators expanding memory on the validated ASRock WRX90 WS EVO platform where ECC RDIMMs are required. Builders using consumer motherboards without registered DIMM support or systems needing non-ECC UDIMMs should look at different memory types. Workstations requiring higher capacities per slot will need larger modules.

Single spec that decides fit: DDR5 ECC RDIMM

The registered ECC design with 288-pin DDR5 interface is the deciding factor for compatibility. Only motherboards that explicitly accept DDR5 RDIMMs with ECC can use this module. The ASRock WRX90 WS EVO is the validated target; other platforms must confirm registered DDR5 support before purchase.

Questions about this item

Does this 288-pin DDR5 RDIMM require an ASRock WRX90 WS EVO motherboard to function?

Yes, the module is validated for the ASRock WRX90 WS EVO platform and must be installed in a compatible DDR5 RDIMM slot on that motherboard.

Will this 1Rx8 CL40 registered ECC module operate correctly alongside other DDR5 4800 registered DIMMs already in the system?

It can run with other DDR5 4800 registered ECC DIMMs, though the memory controller will set a common speed and latency for all populated slots.

How can I confirm the module is running at DDR5 4800 with CL40 timings after installation?

Check the BIOS memory information or use a system utility such as CPU-Z to verify the reported speed of 4800 MT/s and CAS latency of 40.
