32 GB DDR4-2666 ECC RDIMM for Lenovo ThinkSystem

This 32 GB DDR4-2666 ECC registered DIMM is built for the Lenovo ThinkSystem SR550 server. It delivers error-correcting code protection and registered signal processing for stable operation in memory-intensive workloads. The module runs at 1.20 V with a CAS latency of CL19.

Verify DDR4 slot availability

Before ordering, confirm the SR550 has free 288-pin DIMM slots and that the system board supports 32 GB modules at 2666 MHz. Check the server documentation for qualified memory configurations and population rules to ensure compatibility. The module is RoHS certified and carries a lifetime warranty.

Upgrades from smaller or non-ECC DDR4 modules

Replacing lower-capacity or non-ECC DDR4 DIMMs with this 32 GB registered kit adds error correction and increases total memory headroom for virtualisation or database tasks. The jump is worth it when workloads demand data integrity and the SR550 memory topology allows registered modules in the target slots.

Questions about this item

Does the box contain the 32 GB DDR4-2666 ECC RDIMM module only, or are any extra brackets or cables included?

The package supplies the single 32 GB DDR4-2666 ECC registered DIMM with 288 pins and CL19 timing. No additional brackets, cables or cooling parts are included.

Should I pick the 32 GB stick or combine smaller modules to reach the same capacity in my ThinkSystem SR550?

Using one 32 GB DDR4-2666 ECC RDIMM leaves more free slots for future expansion and matches the server's registered memory requirement. Smaller modules would occupy extra slots without adding speed.

What does the 2666 MHz rating mean for actual throughput once the module is installed in the SR550?

The DDR4-2666/PC4-21300 specification delivers up to 21300 MB/s peak bandwidth per module at 1.20 V, with ECC error correction and registered signal processing active.
