Rank 2Rx8

  • 128 GB capacity across four 32 GB modules for heavy workloads
  • DDR5 6800 MT/s speed with CL34 latency for fast response
  • Registered ECC RDIMM design for data integrity
  • Intel XMP 3.0 profile for automatic overclocking
  • 40 V operation with integrated heat spreader

Server-grade DDR5 RDIMM kit

This 128GB kit contains four 32GB DDR5-6800 registered DIMMs with CL34 latency and ECC. It targets workstations and high-end desktops that require registered memory with data-integrity features. The modules run at 1.40V and support Intel XMP 3.0 profiles for automatic configuration.

Overclockable registered ECC memory

Unlike standard server RDIMMs locked to JEDEC speeds, these modules ship rated for 6800MT/s with tight 34-44-44 timings. The jump is worthwhile when a platform supports DDR5 RDIMM overclocking via XMP 3.0 and the workload benefits from higher bandwidth without sacrificing registered signal integrity or multi-bit error correction.

Creators and data-science professionals

Suits users who need high-capacity registered ECC memory with enthusiast-grade speed profiles on compatible Intel or AMD workstation platforms. Not for consumer motherboards that accept only unbuffered UDIMMs, nor for systems that cannot supply 1.40V or lack XMP 3.0 support for the rated frequency.

Questions about this item

Does the 288-pin RDIMM form factor fit standard DDR5 server slots?

Yes, the 288-pin DDR5 RDIMM design matches the industry-standard DDR5 registered DIMM slot used on compatible workstation and server motherboards.

How is the Intel XMP 3.0 profile enabled on these modules?

Enter the system BIOS, locate the memory or overclocking section, and select the XMP 3.0 profile to apply the rated 6800 MT/s speed, CL34 timings and 1.40 V voltage automatically.

When should the registered ECC RDIMMs be replaced in a continuous workload?

Registered ECC RDIMMs have no fixed replacement interval; monitor system logs for corrected or uncorrected ECC errors and replace a module if error counts rise or stability degrades.
