Capacity 128GB (8 x 16GB)

Speed DDR5 6400 (PC5 51200)

  • 128 GB total capacity for heavy workloads
  • DDR5 6400 speed with CL32 latency
  • ECC registered design detects and corrects data errors
  • 4 V XMP profile enables overclocking on W790
  • 10-layer PCB and thermal sensor ensure stable operation

Built for W790 workstations

This 128GB kit contains eight 16GB DDR5 registered DIMMs tested for Intel W790 workstation motherboards. ECC error correction and on-die thermal monitoring protect data integrity during long compute sessions. The modules are not compatible with standard desktop or laptop platforms.

Registered ECC at 6400MT/s with CL32

The kit runs at DDR5 6400 with timings of 32-39-39-102 at 1.4V via Intel XMP. Registered buffering and ECC are mandatory for W790 memory controllers; unbuffered or non-ECC DIMMs will not function in these systems.

Sustained reliability through thermal sensing

Each module includes a built-in sensor that tracks temperature across the 0 to 85°C operating range, allowing the platform to throttle before overheating occurs. Ten-layer PCBs and SK hynix ICs maintain signal integrity under continuous multi-threaded workloads.

Questions about this item

What does the 6400MHz speed mean for my W790 workstation?

The modules run at DDR5 6400 (PC5 51200) with CL32 latency, delivering high bandwidth for memory-intensive workloads on supported W790 platforms.

How does the registered ECC design affect compatibility and data integrity?

Registered ECC R-DIMM modules add a register for signal stability and error correction, requiring a W790 workstation motherboard that supports registered memory.

Will the 288-pin DDR5 R-DIMM modules fit my W790 motherboard slots?

Yes, the 288-pin DDR5 R-DIMM form factor matches W790 workstation memory slots; the kit includes eight 16GB modules for full population.
