Compatible DDR5 ECC RDIMM for ASRock W790 WS

This 16GB DDR5 4800MHz registered DIMM is built for the ASRock W790 WS workstation motherboard. It delivers error-correcting code memory for data integrity in professional workloads. The module operates at 1.1V with CL40 latency and a single-rank 1Rx8 organisation. It suits system builders who need validated server-class memory for this specific platform.

Suited for ECC workstations, not standard desktops

This memory fits professionals running workstations that require registered ECC modules on the W790 WS board. It is not for standard desktop PCs or consumer motherboards that accept only unbuffered non-ECC DDR5. Buyers who need higher capacity per slot or faster speeds should look at other qualified modules. Systems without RDIMM support cannot use this part.

Registered ECC RDIMM with CL40 timing at 4800MHz

The defining specification is the registered ECC RDIMM format combined with DDR5 4800MHz speed and CL40 latency. This combination determines compatibility with the ASRock W790 WS workstation motherboard. The 1.1V voltage and 288-pin DDR5 interface are standard for this module type. Verify your motherboard requires registered ECC memory before purchasing.
