Lenovo ThinkSystem 4X77A94006 compatible DDR5 RDIMM

This 64GB DDR5 4800MHz ECC registered DIMM is validated for Lenovo ThinkSystem servers using Intel processors. It targets administrators who need single-module capacity expansion in mission-critical environments.

Registered ECC design for server motherboards

The 2Rx4 registered architecture adds a buffer between the memory controller and DRAM chips, reducing electrical load on the CPU bus. ECC circuitry detects and corrects single-bit errors to protect data integrity under sustained workloads.

1.1V operation with major OEM DRAM chips

Modules use Samsung, Micron or Hynix components tested under load before shipment. The low 1.10V voltage aligns with DDR5 baseline power targets for dense server configurations.

Questions about this item

Does the CL40 latency become a bottleneck under sustained server workloads?

CL40 is the rated CAS latency at DDR5 4800 speed; it is the primary timing figure that determines access delay during continuous operation.

How much heat does the 1.1V registered module generate when running 24/7?

The module operates at 1.10V without a heat spreader; registered DDR5 RDIMMs at this voltage typically stay within standard server thermal limits under constant load.

Which Lenovo ThinkSystem servers accept this 288-pin 2Rx4 RDIMM?

It is validated for Lenovo ThinkSystem platforms that use the 4X77A94006 part number and support DDR5 4800 ECC registered memory.
