ASRock W790 WS DDR5 Kit

This 128 GB kit contains two 64 GB registered DDR5 modules built for the ASRock W790 WS workstation motherboard. ECC and registered signalling protect data integrity in professional server and workstation workloads. The modules run at 4800 MT/s with a CL40 latency at 1.1 V.

128 GB ECC Registered Capacity

Two 64 GB 2Rx4 modules provide 128 GB of error-correcting memory for large datasets, virtualization and rendering tasks. Registered buffering reduces electrical load on the memory controller, allowing stable operation at full capacity. Systems needing more than 128 GB must add further compatible kits.

DDR5 4800 PC5-38400 Interface

The kit operates at the DDR5 4800 standard (PC5-38400) with 288-pin RDIMM form factor. Bandwidth and latency are fixed by this JEDEC speed grade; higher frequencies are not supported by this module. Compatibility is validated for the ASRock W790 WS platform only.

Questions about this item

Will this 2Rx4 DDR5 4800 CL40 kit run correctly with other DDR5 RDIMMs already installed in my ASRock W790 WS?

Mixing ranks, speeds or latencies can prevent the system from training; for stable operation populate all slots with identical 2Rx4 DDR5 4800 CL40 modules.

How can I confirm the ECC function is active after installing these 1.1 V 288-pin modules?

Enter the BIOS and verify ECC is enabled, then run a memory diagnostic to confirm error detection and correction are working.

Does the package include only the two 64 GB RDIMMs or are any cables or brackets supplied?

The kit contains only the two 64 GB DDR5 4800 ECC RDIMM modules; no cables, brackets or additional accessories are included.
