64 GB DDR4 3200 ECC RDIMM

This 64 GB registered DDR4 module runs at 3200 MT/s with CL22 latency and 1.20 V operation. It uses a 4Rx4 organisation and 288-pin form factor for ThinkMate server platforms. ECC and registered buffering protect data integrity in multi-socket environments.

Who this suits and who should look elsewhere

IT teams expanding ThinkMate HDX-XN24 or HDX-XN12 servers with validated ECC memory will find direct compatibility. Builders needing unbuffered UDIMMs, lower capacities, or non-ECC modules for workstations cannot use this registered DIMM.

Deciding specification — 4Rx4 registered ECC

The 4Rx4 registered ECC design determines whether the motherboard memory controller can address this module. Verify the server qualification list before purchase because unregistered or different-rank DIMMs will not function in these slots.

Questions about this item

Will this 288-pin DDR4 RDIMM fit the memory slots on my ThinkMate HDX-XN24-52S3 server?

Yes, the module is a 288-pin DDR4 RDIMM designed for ThinkMate HDX-XN24-52S3, HDX-XN24-32S3, HDX-XN12-52S3 and HDX-XN12-32S3 servers.

What is the correct way to seat this registered ECC module so the system recognises the full 64 GB?

Align the notch on the 288-pin edge connector with the slot key, press firmly until both retention clips click, then verify in BIOS that the 4Rx4 rank appears at 3200 MT/s.

When should I consider replacing this 1.20 V DDR4 module in a 24/7 server workload?

Replace if memory diagnostics report uncorrectable ECC errors, the system logs repeated corrected errors, or the module fails to train at CL22 during POST.
