128 GB DDR5 ECC RDIMM kit

This NEMIX RAM kit provides 128 GB of DDR5 memory in eight 16 GB modules. It is built for ThinkMate Supermicro SuperServer 621P-TR, 621P-TRT and SuperServer 221P-C9R systems. The modules are registered ECC RDIMMs designed for server and workstation workloads.

Suited for ThinkMate server upgrades.

This kit suits administrators upgrading compatible ThinkMate Supermicro servers that require registered ECC memory. Builders needing unbuffered UDIMMs, non-ECC modules or laptop SO-DIMMs should look at other memory types.

DDR5 4800 PC5-38400 CL40 1.1 V registered ECC

The decisive specification is DDR5 4800 (PC5-38400) with CL40 latency at 1.1 V in a registered ECC RDIMM form factor. Only systems that support this exact speed, voltage and registered ECC protocol can use the kit.

Questions about this item

Should I pick the 128GB kit of eight 16GB modules or a smaller capacity for my Thinkmate server?

The 128GB kit fills eight slots with 16GB each, matching the 1Rx8 registered DDR5 layout validated for Thinkmate Supermicro 621P-TR and 221P-C9R systems.

What does the 4800 MT/s rating actually deliver inside a registered DDR5 server board?

At 4800 MT/s the modules run at PC5-38400 bandwidth with CL40 latency at 1.1V, giving the rated throughput the platform’s memory controller expects.

How does the 288-pin DDR5 RDIMM interface limit speed or capacity in practice?

The 288-pin registered DDR5 form factor locks in ECC and 1Rx8 organisation, so the kit operates at the specified 4800 MT/s without overclock headroom.
