512GB DDR5 ECC RDIMM kit for ASRock W790 WS

This 512GB kit contains eight 64GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It is built for the ASRock W790 WS workstation motherboard and targets professionals who need maximum registered memory capacity for compute-intensive workloads.

Installation notes and common issues

The modules are 288-pin DDR5 RDIMMs that install in the standard DIMM slots of the W790 WS board. Registered ECC memory must be populated according to the motherboard manual; incorrect slot order or mixing with unbuffered DIMMs will prevent the system from posting. Heat spreaders are not present, so airflow across the sticks should be verified in dense configurations.

DDR5 4800 registered ECC limits

The kit runs at the DDR5 4800 JEDEC base speed with 1.10V voltage and CL40 timings. Registered ECC operation adds a clock cycle of buffering, which caps maximum frequency compared to unbuffered alternatives. Total capacity is fixed at 512GB across eight slots; expansion beyond this kit requires a different motherboard platform.
