Thinkmate 511E-WR 521E-WR Server Memory Upgrade

This NEMIX RAM module adds 64GB of DDR5 capacity to compatible Thinkmate SuperServer 511E-WR and 521E-WR systems. It is built for IT professionals who need registered ECC memory that has been validated for mission-critical workloads. The single-module design simplifies installation in servers with limited DIMM slots. Buyers who need unbuffered memory or desktop DDR5 should look elsewhere.

DDR5 4800 Registered ECC Interface Limits

The module runs at 4800 MT/s with a CAS latency of CL40 and operates at 1.10V. Registered buffering and on-die ECC protect data integrity but add one cycle of latency compared with unbuffered DIMMs. The 288-pin RDIMM form factor fits only DDR5 server motherboards that support registered memory. Systems requiring load-reduced or non-ECC modules will not accept this part.

Single 64GB 2Rx4 Module Capacity Constraint

One 64GB dual-rank module provides the full capacity upgrade in a single slot. The 2Rx4 organisation maximises density while keeping the rank count manageable for the memory controller. Servers that require populated slots in specific channels or that limit total rank count per channel must verify their qualified vendor list before purchase.

Questions about this item

Is this a single 64 GB module or a multi-stick kit?

The package contains one 64 GB DDR5 4800 RDIMM, so you add the full capacity in a single slot.

What does the 4800 MT/s rating deliver inside a ThinkMate 511E-WR or 521E-WR?

The module runs at DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V, providing registered ECC bandwidth for the server's memory controller.

Does the 288-pin RDIMM interface limit the maximum speed in these systems?

The 288-pin DDR5 RDIMM form factor supports the rated 4800 MT/s; the server's memory controller determines the final operating speed.
