Capacity and configuration

This kit provides 1TB of memory using eight 128GB DDR5 RDIMMs. Each module operates at 4800MT/s with a CAS latency of CL40 and runs at 1.1V. The 4Rx4 organisation and registered design suit high-density server and workstation platforms.

Motherboard slot and voltage check

Verify that the ASRock W790 WS motherboard has eight free DDR5 RDIMM slots and that the BIOS supports 4Rx4 registered modules at 1.1V. Confirm the board's qualified vendor list includes this part number before ordering.

Sustained load behaviour

Registered ECC modules correct single-bit errors continuously during long compute runs. The 1.1V operating voltage keeps power draw steady across extended workloads. Eight ranks per channel maintain signal integrity when all slots are populated for hours.
