64GB DDR5 ECC RDIMM for Lenovo ThinkStation PX

This 64GB DDR5 4800 module delivers ECC registered memory for the Lenovo ThinkStation PX workstation. It operates at 1.1V with CL40 latency and a 2Rx4 rank configuration. The 288-pin RDIMM form factor fits the platform's DDR5 slots directly.

IT professionals needing registered ECC capacity

This module suits administrators expanding memory in supported Lenovo workstations where registered ECC is required. It is not for buyers who need unbuffered non-ECC memory, desktop consumer DIMMs, or modules validated for other OEM platforms.

Verify DDR5 RDIMM slot availability

Confirm the workstation has a free 288-pin DDR5 slot that accepts registered ECC RDIMMs. Check the system documentation for the maximum supported registered memory per channel and total capacity before ordering.

Questions about this item

Does this 64 GB DDR5 4800 ECC RDIMM require a Lenovo ThinkStation PX workstation to operate?

The module is validated for Lenovo ThinkStation PX systems and uses the standard 288-pin DDR5 RDIMM form factor with 1.10 V operation.

Can this CL40 2Rx4 registered DIMM share memory channels with older DDR5 RDIMMs of different speeds or ranks?

Mixing modules with different CAS latencies, ranks or data rates on the same channel is not recommended and may prevent the system from posting.

How can I confirm the 64 GB 2Rx4 ECC RDIMM is running at 4800 MT/s with error correction active after installation?

Check the BIOS memory information screen or the operating system memory report for 4800 MT/s speed, CL40 timings and ECC enabled status.
