System-Specific DDR5 Kit

This NEMIX RAM kit delivers 128 GB across four 32 GB registered DDR5 modules built for Thinkmate SuperServer 511E-WR and 521E-WR platforms. Each module runs at 4800 MT/s with CL40 latency at 1.1 V and uses 1Rx4 organisation with ECC for data integrity. The 288-pin RDIMM form factor matches the server memory slots exactly.

Who This Suits and Who It Does Not

Administrators expanding Thinkmate SuperServer 511E-WR or 521E-WR systems to 128 GB with validated ECC registered memory will find this kit a direct fit. Buyers who need unbuffered UDIMM modules, a different capacity per module, or memory for non-Thinkmate platforms should look elsewhere because this kit is qualified only for the listed servers.

Deciding Specification: Registered ECC DDR5 4800

The single specification that decides compatibility is the registered ECC DDR5 4800 RDIMM design with 1Rx4 ranking at 1.1 V. Only systems that require this exact registered ECC module type, speed, voltage and rank configuration can use the kit; any other memory architecture will not function in the target servers.

Questions about this item

Does the 1.10V DDR5 4800 kit run hot or loud in a Thinkmate SuperServer 511E-WR under continuous load?

The modules operate at 1.10V without a heat spreader; server chassis airflow handles cooling, and memory itself produces no noise.

What must the Thinkmate SuperServer 511E-WR already have to accept this 128GB 288-pin DDR5 RDIMM kit?

The system needs four free DDR5 RDIMM slots and a BIOS that supports 1Rx4 registered ECC modules at 4800 MT/s.

Can I mix these 32GB CL40 1Rx4 sticks with older DDR5 RDIMMs already in the Thinkmate 521E-WR?

Mixing ranks, speeds or latencies is not recommended; the server will downclock all channels to the slowest module and may disable ECC.
