Workstation DDR5 upgrade for W790 platforms

This V-color TR564G56D436Q kit delivers 256GB of DDR5 ECC Registered memory across four 64GB modules. It is built for Intel XMP-enabled W790 workstation motherboards and is not compatible with standard desktop PCs or laptops.

Registered ECC with 2Rx4 organisation

Each module uses SK Hynix ICs in a 2Rx4 configuration running at 5600MT/s with CL36-38-38-80 timings at 1.25V. The registered buffer and error-correcting code provide the data integrity required by workstation workloads.

Thermal sensor and 10-layer PCB

A built-in sensor monitors operating temperatures from 0 to 85°C while the premium 10-layer PCB and heat spreader maintain signal integrity. Every module is validated for voltage tolerance and signal quality before shipping.
