V-color OC R-DIMM DDR5 256GB (8×32GB) 5600 CL36 W790

Workstation 256 GB DDR5 kit

This V-color OC R-DIMM kit delivers 256 GB across eight 32 GB registered modules for W790 workstation motherboards. It runs at DDR5 5600 with CL36 timings and uses SK Hynix ICs on 10-layer PCBs with heat spreaders. ECC and registered buffering provide data integrity for professional workloads. The kit is validated for Asus PRO WS W790E-SAGE SE boards and operates from 0 to 85 °C.

Replaces standard RDIMM or non-ECC memory

Moving from unbuffered or non-ECC DDR5 adds error correction and signal stability for multi-socket or high-capacity configurations. The jump is worth it when workloads demand 256 GB density and registered signalling on W790 platforms. Standard desktop DDR5 will not fit or function in these slots. Buyers who need consumer desktop compatibility cannot use this kit.

DDR5 5600 registered interface limits

The DDR5 5600 registered interface tops out at 5600 MT/s with 1.25 V operation and CL36-38-38-80 timings on this kit. Registered buffering adds one cycle of latency versus unbuffered modules. Eight 1Rx4 ranks per channel can stress the memory controller at maximum population. Systems without W790 chipset support will not boot with these modules.
