  • Rated speedDDR4 3200 (PC4 25600)
  • ChipsetMajor OEM Samsung, Micron, Hynix
  • CAS latencyCL22
  • Buffer typeRegistered
  • Rated voltage1.2 V
  • 512 GB total capacity from eight 64 GB modules
  • DDR4 3200 speed rated at PC4-25600 bandwidth
  • ECC registered RDIMM design protects data integrity
  • 20 V operation keeps power draw low
  • Validated for ThinkMate RAX-XS4 and RAX-XH2 rackmount servers

Server-grade capacity

This 512GB kit assembles eight 64GB DDR4 3200 registered ECC modules for THINKMATE RAX-XS4-21S1-10G, RAX-XS4-11S1-10G and RAX-XH2-11S3 rackmount servers. The 4Rx4 organization and 1.20V operation match the platform memory controller requirements for high-density configurations. Builders who need more than eight slots or a different form factor cannot use this kit.

Straightforward module installation

The 288-pin RDIMM form factor seats in standard DDR4 server DIMM sockets without tools. Populate all eight channels in the order specified by the system manual to enable full bandwidth; mismatched slot population is the most common cause of POST failures with 4Rx4 modules. No heat spreaders are fitted, so airflow clearance follows the chassis design.

Steady throughput under load

Registered buffering and on-die ECC maintain data integrity during sustained write-heavy workloads such as database checkpointing or virtualization memory overcommit. CL22 latency at 3200 MT/s delivers predictable bandwidth when all ranks are active across the 512GB array. Modules are stress-tested at rated voltage before shipping to reduce early-life failures.

Questions about this item

How do I verify the 512GB kit runs at DDR4 3200 CL22 after installation?

Enter the server BIOS or UEFI and confirm the memory speed reads 3200 MT/s with CAS latency 22; the ECC status should show enabled for each of the eight 64GB modules.

What ships in the package and is anything else required for the THINKMATE rackmount servers listed?

The box contains eight 64GB 288-pin DDR4 RDIMMs totalling 512GB; no extra cables, brackets or cooling parts are needed for the compatible RAX-XS4-21S1-10G, RAX-XS4-11S1-10G or RAX-XH2-11S3 systems.

Which capacity and rank option matches the MR25600-944K8 part for my server?

Choose the 512GB kit built from eight 64GB 4Rx4 registered ECC modules; this is the only configuration covered by part number MR25600-944K8.
