256GB DDR5 6400 ECC Registered kit

This kit provides 256GB across eight 32GB DDR5 RDIMMs rated at 6400MT/s with CL40 latency. Registered ECC operation and a 1.4V profile target data integrity for W790 workstation motherboards. A ten-layer PCB and Hynix ICs underpin the overclocking specification.

W790 workstation builds only

The modules are validated exclusively for W790 workstation boards such as the Asus PRO WS W790E-SAGE SE and will not function in standard desktop PCs or laptops. Buyers needing memory for consumer platforms should select standard UDIMM kits instead.

Heat spreader and thermal sensor included

Each DIMM carries an integrated heat spreader and an on-board thermal sensor that monitors temperature across the 0 to 85°C operating range. These features support sustained reliability during extended workloads without additional accessories.

Questions sur cet article

Does this 256GB DDR5 6400 kit require a W790 workstation motherboard to function?

Yes, it is designed exclusively for W790 workstation motherboards and is not compatible with standard desktop PCs or laptops.

Will these registered ECC modules work if I keep my existing non-ECC DDR5 memory installed?

No, registered ECC RDIMMs cannot be mixed with unbuffered non-ECC UDIMMs; the system requires a uniform memory configuration.

How can I confirm the kit is running at its rated 6400MHz CL40 speed after installation?

Enable the Intel XMP profile in the motherboard BIOS, then verify the operating frequency and 32-39-39-102 timings using CPU-Z or the system firmware.
