ThinkMate DDR5 ECC RDIMM kit

This 64GB kit contains four 16GB DDR5 4800 registered DIMMs built for ThinkMate SuperServer 511E-WR and 521E-WR platforms. Each module operates at 1.10V with CL40 latency and 1Rx8 organisation. The memory is new and validated for server workloads requiring error-correcting code.

Suited for ThinkMate server upgrades

Administrators expanding capacity in 511E-WR or 521E-WR chassis will find the kit a direct fit. Systems that require unbuffered UDIMMs, non-ECC modules or a different pin count cannot use these registered DIMMs. Buyers needing speeds beyond 4800MT/s or lower CAS latency should evaluate other options.

Registered DDR5 for multi-slot servers

The 288-pin RDIMMs plug into compatible ThinkMate motherboards without additional cooling hardware. Registered buffering reduces electrical load on the memory controller, freeing headroom for fully populated slots. ECC circuitry corrects single-bit errors, protecting data integrity in continuous operation.

Questions about this item

Do I need a THINKMATE Supermicro SuperServer 511E-WR or 521E-WR system to install this 64GB kit?

Yes, this 4 x 16GB DDR5 4800 CL40 ECC RDIMM kit is validated for the THINKMATE SuperServer 511E-WR and 521E-WR platforms and requires a motherboard with 288-pin DDR5 RDIMM slots.

Can I add this registered ECC kit alongside non-ECC UDIMMs already in the server?

No, registered ECC RDIMMs cannot be mixed with unbuffered non-ECC UDIMMs; the memory controller requires all installed modules to be registered ECC RDIMMs.

How can I confirm the kit is running at DDR5 4800 with CL40 timings after installation?

Enter the system BIOS or use a hardware information utility to verify the memory reports 4800 MT/s, CL40 latency, 1.10 V and registered ECC operation.
