256 GB DDR5 ECC RDIMM kit

This 256 GB kit contains eight 32 GB DDR5 4800 registered DIMMs with ECC and a CL40 latency. It is built for the ASRock W790 WS workstation motherboard and suits professionals who need maximum memory capacity for virtualization, rendering or large dataset workloads.

Verify W790 WS slot population rules

Confirm that the ASRock W790 WS board accepts eight registered DIMMs at the rated speed and that your CPU supports the full 256 GB configuration. Check the motherboard manual for required slot order and any BIOS version needed for eight-module operation.

Sustained load stability with ECC

Registered modules and on-die ECC maintain data integrity during continuous multi-threaded workloads such as compile farms or simulation runs. The 1.1 V operating voltage keeps power draw consistent across all eight sticks during extended sessions.

Questions sur cet article

What comes in the 256GB kit and do I need anything else to install it?

The kit contains eight 32GB DDR5 4800 CL40 ECC RDIMM modules. No extra parts are required; install them directly into the 288-pin slots on the ASRock W790 WS motherboard.

Why choose this 8x32GB kit instead of a different capacity or speed?

This kit provides the full 256GB capacity at DDR5 4800 with CL40 latency and 1.1V operation, matching the W790 WS platform's supported memory specification.

What does the CL40 rating mean for real-world workloads on the W790 WS?

CL40 is the CAS latency at 4800 MT/s; it determines the delay before data is available and is the standard timing for DDR5 4800 ECC RDIMMs on this platform.
