Server DDR4 32GB ECC RDIMM

This 32GB DDR4 2666 ECC RDIMM module is built for servers and workstations that require registered memory with error correction. It delivers 2666MHz speed at the standard 1.20V voltage in a single 288-pin DIMM. The 2Rx4 rank organisation suits platforms that specify this exact configuration.

Registered ECC with 2Rx4 layout

The registered buffer and ECC functionality are the decisive specifications; the module will only operate in systems that explicitly support DDR4 RDIMM with a 2Rx4 rank structure. CL19 latency and PC4-21300 bandwidth are fixed characteristics of this part. Verify the platform memory list before purchase.

Single-module upgrade for compatible platforms

Installs into an available 288-pin DDR4 RDIMM slot and requires a motherboard and CPU that accept registered ECC memory at 2666MHz. It adds 32GB of capacity without occupying additional slots. Systems needing unbuffered UDIMM or a different rank layout cannot use this module.

Questions about this item

What does the 32 GB capacity mean once installed in a server?

It adds a single 32 GB registered DIMM, giving the system one more rank of ECC memory for larger workloads and virtualization tasks.

How does the DDR4 2666 interface limit real-world throughput?

The module runs at 2666 MT/s with CL19 timing, so peak transfer rate is capped at the PC4-21300 specification for each channel.

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

It fits a standard DDR4 288-pin DIMM socket and requires the motherboard to support registered ECC modules with 2Rx4 organization.
