Capacity and Configuration

This kit provides 768GB of DDR4 memory across twelve 64GB registered DIMMs. It is built for ThinkMate GPU-optimised servers that require very large memory footprints for multi-GPU workloads and virtualisation.

DDR4 3200 Registered ECC Limits

The modules run at DDR4 3200 with CL22 latency and 1.20V operation. Registered buffering and ECC protect data integrity, but the DDR4 bus caps peak bandwidth at the PC4-25600 rate regardless of how many DIMMs are populated.

Headroom and Constraints

Twelve slots are needed to reach the full 768GB, so the server must expose at least twelve DDR4 RDIMM sockets. Systems with fewer slots or platforms that only accept unbuffered UDIMMs cannot use this kit.

Questions about this item

Should I choose the 12x64GB kit or populate with fewer modules?

The kit supplies 768GB across twelve 64GB RDIMMs; install all twelve to reach the rated capacity or populate a multiple of twelve slots for balanced channels.

What does the 3200 CL22 rating deliver in a ThinkMate server?

The modules run at DDR4 3200 with CAS 22 latency, providing 25600 MB/s peak bandwidth per module when the platform trains at that speed.

Does the 288-pin RDIMM interface limit the maximum speed?

The 288-pin DDR4 RDIMM form factor is specified for 3200 MT/s; the registered design and 4Rx4 organisation let the memory controller drive the rated 25600 MB/s per module.
