768 GB DDR4 ECC RDIMM kit

This NEMIX RAM kit delivers 768 GB across six 128 GB registered DIMMs. It is built for ThinkMate GPU-optimised servers that require DDR4 3200 ECC memory. The modules target IT teams running memory-intensive workloads on qualified platforms.

DDR4 3200 registered bandwidth ceiling

The PC4-25600 interface caps throughput at the DDR4 3200 transfer rate. CL22 latency and 4Rx4 organisation define the timing envelope. Registered buffering adds a cycle, so peak bandwidth is limited by the DDR4 standard itself.

288-pin registered modules without spreaders

Each stick uses a standard 288-pin RDIMM connector and runs at 1.20 V. The bare PCB design means clearance depends on the server chassis and CPU cooler layout. Six modules occupy every slot in a typical 24-slot bank.

Questions about this item

Should I choose the 768GB kit with six 128GB modules or a different capacity for my Thinkmate server?

This kit provides 768GB total using six 128GB modules, filling six DIMM slots for maximum density in compatible Thinkmate GPU-optimized servers.

What does the DDR4 3200 CL22 rating mean for actual throughput in my system?

The modules run at 3200 MT/s with CAS latency 22, delivering PC4-25600 bandwidth when the platform supports that speed and timing.

How does the 288-pin DDR4 RDIMM interface limit what I can install?

The 288-pin RDIMM form factor fits only DDR4 registered DIMM slots; it cannot be used in UDIMM, SO-DIMM or DDR5 sockets.
