Rank 2Rx4

  • 32GB capacity expands server memory headroom for demanding workloads
  • DDR4 2666MHz speed delivers high bandwidth for data-intensive tasks
  • ECC registered design detects and corrects errors to protect data integrity
  • 2V operation reduces power draw and heat in dense configurations
  • Backward compatible with 2133MHz and 2400MHz systems for flexible deployment

Server memory upgrade

This 32GB DDR4 module is built for servers, workstations and NAS systems that require registered ECC memory. It will not work in standard desktop computers and cannot be mixed with unbuffered modules.

Registered ECC RDIMM

The single rank 2Rx4 registered DIMM provides error correction and signal buffering required by multi-socket server platforms. Standard desktop boards lack the chipset support for this registered ECC configuration.

Low-voltage operation

Rated at 1.2V, the module runs at standard DDR4 voltage without a heat spreader. Backward compatibility with 2133MHz and 2400MHz systems allows installation in older platforms while maintaining JEDEC-compliant thermal limits.

Questions sur cet article

What does the 2666MHz speed mean once the module is installed in a server?

The module runs at 2666MHz by default and will downclock to 2400MHz or 2133MHz if the platform requires a lower speed.

How does the PC4-21300 rating affect real-world bandwidth?

PC4-21300 is the JEDEC peak transfer rate for DDR4-2666; actual throughput depends on the memory controller and channel configuration.

What physical slot and clearance does this 288-pin RDIMM need?

It fits a standard DDR4 288-pin RDIMM socket and has no heat spreader, so it clears most CPU coolers and dense server chassis.
