Speed DDR5 6400 (PC5 51200)

  • 64 GB capacity across four 16 GB modules for large workloads
  • DDR5 6400 speed with CL32 timing for responsive data throughput
  • ECC registered design detects and corrects errors for workstation reliability
  • Built-in thermal sensor monitors temperature from 0 to 85 °C
  • Validated on 10-layer PCB with SK Hynix ICs for signal integrity

W790 workstation ECC RDIMM kit

This V-color DDR5 kit provides 64 GB across four 16 GB registered DIMMs running at 6400 MHz with CL32 timings. It uses SK Hynix ICs on 10-layer PCBs and includes on-board ECC plus a thermal sensor rated for 0 to 85 °C operation. The modules are validated for Intel XMP on W790 workstation motherboards only.

Suited for ECC workstations, not desktops

Builders configuring W790 workstations that require registered ECC memory with XMP support will find this kit compatible. Buyers who need memory for standard desktop PCs or laptops cannot use these modules because they are electrically and mechanically incompatible with consumer platforms.

Sustained load behaviour with thermal sensor

Under continuous workloads the integrated thermal sensor monitors module temperature to prevent overheating within the 0 to 85 °C range. ECC corrects single-bit errors in real time while registered buffering reduces electrical load on the memory controller during extended sessions.

Questions about this item

Do I need a W790 workstation motherboard to use this 64GB DDR5 6400MHz CL32 ECC RDIMM kit?

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

Can I mix these 16GB 1Rx8 registered ECC modules with older unbuffered non-ECC DDR5 DIMMs in the same system?

No, registered ECC RDIMMs cannot be mixed with unbuffered non-ECC memory; the platform requires all slots to use registered ECC modules.

How can I confirm the kit is running at its rated 6400MHz CL32 with the XMP profile active after installation?

Enter the BIOS and verify the memory frequency reads 6400MT/s with timings 32-39-39-102, and check that the XMP profile is enabled.
