Capacity and configuration

This kit supplies 256GB of DDR4 memory across four 64GB registered DIMMs. Each module runs at 3200MHz with CL22 latency and a 1.2V operating voltage. The 4Rx4 organisation and ECC registration target enterprise workloads that require maximum density per slot.

Suited for ThinkMate rackmount servers

The memory is validated for ThinkMate RAX-PT10-11A1, RAX-PT8-12A1 and RAX-PT12-12A1 rackmount servers. Builders using other server platforms or consumer motherboards cannot use these registered ECC modules, as those systems require unbuffered non-ECC memory.

Registered ECC RDIMM requirement

The single specification that decides compatibility is the registered ECC RDIMM form factor. Only motherboards designed for DDR4 registered ECC memory with 288-pin slots can accept this kit.

Questions about this item

Should I choose the 4x64 GB kit or look for a different capacity?

This kit provides 256 GB total across four 64 GB registered DIMMs, matching the ThinkMate RAX-PT10-11A1, RAX-PT8-12A1 and RAX-PT12-12A1 memory slots.

What does DDR4 3200 CL22 mean for actual server workloads?

The modules run at 3200 MT/s with a CAS latency of 22 cycles, delivering PC4-25600 bandwidth for ECC-protected data integrity in registered configurations.

Does the 288-pin RDIMM interface limit speed or capacity on my ThinkMate rackmount?

The 288-pin DDR4 RDIMM form factor supports the rated 3200 MT/s and 64 GB per module; the registered buffer and 4Rx4 organisation are designed for the listed ThinkMate platforms.
