384GB DDR4 3200 ECC RDIMM Kit

This 384GB kit contains six 64GB DDR4 3200 registered DIMMs built for Thinkmate rackmount servers. ECC and registered buffering protect data integrity under continuous load. Modules run at 1.2V with CL22 latency and a 4Rx4 organisation. The 288-pin form factor matches the qualified platforms listed by the supplier.

Suited for Thinkmate RAX-PT10-11A1 RAX-PT8-12A1

Administrators expanding memory in those exact Thinkmate models can install this kit with confidence. Builders working with other vendors or consumer motherboards should look elsewhere because the modules are validated only for the named systems. Workstations needing unbuffered memory or non-ECC operation are not a match for this registered ECC design.

384GB total capacity across six slots

The kit fills six DIMM slots with 64GB each, giving 384GB of addressable memory for virtualisation, large databases or high-thread-count compute. Headroom ends when the platform’s maximum supported capacity or slot count is reached. Workloads requiring more than 384GB or a higher memory frequency will need a different configuration.

Questions about this item

Does my Thinkmate rackmount server need a specific BIOS revision to run 4Rx4 registered DIMMs?

The modules are validated for the RAX-PT10-11A1, RAX-PT8-12A1 and RAX-PT12-12A1 platforms; apply the latest vendor firmware before installation to ensure the memory controller recognises the 4Rx4 organisation.

Can I mix these 64 GB 4Rx4 sticks with older 32 GB 2Rx4 DDR4 3200 RDIMMs in the same host?

Mixing ranks changes the electrical load per channel; the server will down-clock to the lowest common timing and may disable ECC scrubbing, so populate identical 4Rx4 modules per channel for full 3200 MT/s operation.

How do I verify the kit is running at 3200 MT/s with ECC active after POST?

Enter the BIOS or UEFI memory information screen and confirm the reported speed shows 3200 MT/s, voltage reads 1.20 V, and ECC status is reported as enabled or active.
