32GB DDR5-4800 ECC RDIMM

This 32GB DDR5 4800 module delivers registered ECC memory for the ASRock W790 WS workstation motherboard. It operates at 1.1V with CL40 latency and a 1Rx4 rank structure. The 288-pin RDIMM form factor targets professionals who need error-correcting capacity for stable compute workloads.

Verify registered DDR5 support

Confirm the motherboard accepts registered DDR5 RDIMMs and check the manual for approved slot configurations before ordering. The module uses a 1.1V operating voltage and 288-pin interface that must match the platform's memory controller requirements. Ensure the BIOS revision supports this capacity and speed combination.

Sustained load stability with ECC correction

Under continuous workloads the registered buffer reduces electrical load on the memory controller while ECC corrects single-bit errors in real time. The CL40 timing and 1.1V operation maintain consistent throughput without thermal throttling concerns on passively cooled modules. This behaviour suits long-running server and workstation tasks where data integrity outweighs peak bandwidth.
