64GB DDR5 4800 ECC RDIMM

This 64GB registered DDR5 module delivers ECC protection and 4800MHz speed for ThinkMate tower servers. It targets IT professionals who need reliable capacity expansion for mission-critical workloads. The single 2Rx4 stick fits 288-pin slots and operates at the standard 1.1V. Compatibility is validated for specific ThinkMate TWX-XS8 configurations.

Thermals noise and power draw

The module runs at 1.10V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering reduces electrical load on the memory controller during sustained operation. ECC circuitry adds minimal overhead while correcting single-bit errors in real time. Power consumption scales with the 4800MHz data rate under typical server loads.

Upgrade path and value

This part replaces lower-capacity or non-ECC DDR5 RDIMMs in supported ThinkMate towers. The jump is worth it when workloads exceed existing memory bandwidth or when error correction becomes a requirement. Systems limited to fewer than 14 or 24 slots benefit most from the high-density 64GB rank. Always verify the exact motherboard qualification list before ordering.

Questions about this item

How do I install this 288-pin DDR5 RDIMM into my THINKMATE TWX-XS8 server, and which step is often missed?

Power down the server, open the chassis, align the module notch with the slot key, press firmly until both retention clips click, then verify in BIOS that the 4800 MT/s speed and ECC are recognised.

What maintenance or replacement will this 64 GB ECC RDIMM need during its service life?

No routine maintenance is required; the module has no heat spreader and operates at 1.10 V. Replace only if diagnostics report uncorrectable ECC errors or the server fails to POST with the module seated.

What limit appears first when this CL40 2Rx4 module runs sustained workloads?

The CAS latency of 40 cycles at 4800 MT/s sets the baseline response time; under continuous load the memory controller will hit this latency ceiling before thermal or voltage limits become a factor.
