Speed DDR5 5600 (PC5 44800)

  • Massive 512GB capacity with eight 64GB modules
  • DDR5 5600 speed delivers high bandwidth for workstation workloads
  • ECC registered design detects and corrects data errors automatically
  • Built-in thermal sensor monitors temperature up to 85°C for reliable operation
  • 10-layer PCB with Hynix ICs tested for voltage, temperature and signal integrity

Built for W790 workstations

This 512GB kit contains eight 64GB DDR5 RDIMMs rated at 5600MHz with CL36 latency. It is engineered specifically for AMD Ryzen W790 workstation motherboards and will not function in standard desktop PCs or laptops.

Registered DIMM installation

Modules are 288-pin registered DIMMs requiring a W790 workstation board with RDIMM support; they will not post in consumer platforms. Each stick uses a 10-layer PCB and SK Hynix ICs tested for voltage, temperature resistance and signal integrity before shipping.

Sustained workload stability

ECC error correction and an on-module thermal sensor monitor operating temperatures from 0 to 85°C during extended compute tasks. The registered buffer and 2Rx4 organisation maintain signal quality across all eight slots under continuous load.

Questions about this item

How do I confirm the 5600MHz CL36 ECC RDIMM kit is running at its rated speed and timings after installation?

Enter the BIOS on the W790 workstation motherboard, enable the Intel XMP profile, and verify the memory reads 5600MHz with 36-38-38-80 timings; the built-in thermal sensor will also report temperatures within the 0 to 85°C operating range.

What is included with the TR564G56D436O kit and do I need any extra components for a W790 workstation build?

The box contains eight 64GB DDR5 288-pin RDIMM modules with heat spreaders, totalling 512GB; no additional memory parts are required for a compatible W790 workstation motherboard.

Which capacity configuration should I choose for a W790 workstation that supports eight-channel memory?

Select the 512GB kit (8 x 64GB) to populate all eight channels with 2Rx4 registered ECC modules running at 5600MHz CL36, matching the motherboard’s optimal memory topology.
