32GB ECC Registered DDR4 for Lenovo ThinkSystem

This 32GB DDR4 2933MHz ECC registered DIMM is built for Lenovo ThinkSystem servers based on Xeon SP Gen 2 platforms. It targets administrators who need error-correcting, registered memory to maintain data integrity in SR530, SR550, SR570, SR590 or SR670 systems.

Fits 288-pin DDR4 slots in compatible ThinkSystem

The module plugs directly into 288-pin DDR4 slots and operates at 1.2V with CL21 latency. It requires a platform that supports ECC registered memory and cannot be mixed with unbuffered modules. Backward compatibility with 2133MHz, 2400MHz and 2666MHz speeds lets it slot into existing configurations without BIOS changes.

Runs at standard 1.2V with no heat spreader

The module draws 1.2V and has no integrated heat spreader, so airflow across the DIMM slots handles cooling. Registered buffering adds a small electrical load but keeps signal integrity stable under sustained server workloads. Power draw and acoustic contribution remain negligible in a properly ventilated chassis.

Klausimai apie šią prekę

Will the 1.2V operating voltage limit performance during sustained server workloads?

The module runs at the standard DDR4 1.2V, which is the JEDEC voltage for 2933MHz operation. No higher voltage is required to reach the rated speed.

How much heat does the 2Rx4 registered DIMM produce when running all day in a ThinkSystem SR550?

The module has no heat spreader and operates at 1.2V. Registered ECC DIMMs of this density typically stay within normal server thermal limits when system airflow is adequate.

Which Lenovo ThinkSystem models must I already own for this 288-pin DDR4 RDIMM to work?

Compatible systems are the ThinkSystem SR530, SR550, SR570, SR590 and SR670 with Xeon SP Gen 2 processors.
