512GB DDR4 3200 ECC RDIMM Kit

This 512GB kit contains four 128GB registered DDR4 modules rated at 3200 MT/s with CL22 latency. It is built for ThinkMate rackmount servers that require ECC registered memory for data integrity in mission-critical workloads.

Capacity and headroom

Four quad-rank 4Rx4 modules deliver 512GB total capacity for heavy virtualization, large databases or in-memory analytics. The 1.2V operating voltage keeps power draw predictable. Systems limited to lower maximum memory per slot or fewer than four slots cannot use the full kit.

Build integration

The 288-pin RDIMM form factor fits standard DDR4 server DIMM slots. Registered buffering reduces electrical load on the memory controller, allowing dense population. Boards that accept only unbuffered UDIMMs or require a different rank configuration will not support these modules.

Questions about this item

Will these 4Rx4 DDR4 3200 ECC RDIMMs run in my Thinkmate RAX-XS4-11S3-SH alongside any older RDIMMs I keep?

The kit uses 4Rx4 DDR4 3200 CL22 1.20 V registered modules; matching rank, speed, voltage and ECC type is required for mixed operation, so older sticks must share those exact specifications.

How can I verify the 512 GB kit is running at 3200 MT/s with ECC active after installation?

Enter the server BIOS or UEFI and confirm the memory frequency reads 3200 MT/s, the total capacity shows 512 GB and ECC status is reported as enabled or active.

Does the MR25600-744K4 package include only the four 128 GB RDIMMs or are any cables or brackets supplied?

The box contains the four 288-pin DDR4 3200 ECC registered RDIMMs and nothing else; no cables, brackets or additional hardware are included.
