Compatible server memory

This 64GB DDR5 module is built for the THINKMATE SuperServer 521C-NR. It delivers registered ECC reliability for mission-critical workloads. The single-stick design simplifies capacity scaling in supported chassis. IT teams specify it for stable, validated upgrades.

Thermals and power

Operating at 1.1V, the module runs cool without a heat spreader. Registered buffering reduces electrical load on the memory controller. Standard airflow in the 521C-NR handles dissipation during sustained throughput. No extra cooling steps are required.

Decisive spec

CL40 latency at 4800MT/s sets the timing envelope for this platform. The 2Rx4 organisation matches the server's memory topology exactly. Buyers needing different latency or rank configurations must select another part.

Questions about this item

How do I install the 288-pin DDR5 RDIMM in the THINKMATE SuperServer 521C-NR, and what step is often missed?

Power down the server, open the chassis, align the module notch with the slot key, press firmly until both ejector tabs click, then verify in BIOS that the 64GB module registers at 4800 MT/s with ECC active.

What maintenance or replacement will this 1.10V ECC registered module need over its service life?

No scheduled maintenance is required; the module has no heat spreader or moving parts. Replace it only if memory diagnostics report uncorrectable errors or if a capacity upgrade is needed.

What limit appears first when this CL40 2Rx4 module runs sustained workloads in the SuperServer 521C-NR?

The memory controller’s maximum supported speed of 4800 MT/s is the first ceiling; the module itself is rated for that speed, so throughput cannot exceed the platform limit.
