ThinkMate Server DDR5 Kit

This NEMIX RAM kit delivers 64 GB of DDR5 4800 registered ECC memory across two 32 GB modules. It is built for ThinkMate SuperServer 511E-WR and 521E-WR platforms that require registered DIMMs with error correction. The modules run at 1.10 V with CL40 latency and use a 1Rx4 organisation based on major OEM DRAM.

Registered ECC for Multi-Socket Builds

Each 288-pin RDIMM presents a registered signal to the memory controller, reducing electrical load on multi-socket server boards. ECC capability detects and corrects single-bit errors, protecting data integrity in virtualisation, database and storage workloads. The kit frees all remaining DIMM slots for future capacity expansion without mixing ranks.

For ThinkMate 511E-WR and 521E-WR Owners

This kit suits administrators upgrading or populating those specific ThinkMate SuperServer models with validated DDR5 registered ECC memory. Builders using consumer motherboards, non-ECC platforms, or servers that require unbuffered DIMMs or different speeds should look elsewhere.

Questions about this item

Does sustained load push the DDR5 4800 CL40 modules past their 1.10 V operating voltage?

No, the registered ECC RDIMMs are specified at 1.10 V and the server platform manages voltage regulation within that limit during continuous operation.

How much heat and noise do the 1Rx4 RDIMMs add when the SuperServer runs all day?

The modules have no heat spreader and draw only 1.10 V, so they add minimal thermal load and zero acoustic noise; system fans handle the airflow.

What must the ThinkMate SuperServer 511E-WR or 521E-WR already have to accept this 288-pin DDR5 ECC RDIMM kit?

The server needs free DDR5 RDIMM slots that support 1Rx4 registered ECC modules at 4800 MT/s and a BIOS that recognises the 64 GB capacity.
