ThinkMate DDR4 ECC RDIMM kit

This 64 GB kit contains eight 8 GB DDR4 3200 registered DIMMs built for ThinkMate HDX server platforms. ECC and registered signalling protect data integrity in multi-socket workloads. The modules run at 1.2 V with CL22 latency and use major OEM DRAM from Samsung Micron or Hynix. No heat spreaders are fitted so airflow clearance remains unrestricted.

Registered ECC at DDR4 3200

The single specification that decides fit is the registered ECC RDIMM interface at DDR4 3200 PC4-25600. Consumer motherboards that accept only unbuffered non-ECC UDIMMs cannot use these modules. Builders who need unbuffered memory or a different speed grade must select another part.

Eight-module kit simplifies population

The package delivers a matched 8 x 8 GB set so all slots can be filled in one step without mixing ranks or capacities. This removes the trial-and-error of sourcing individual sticks and ensures the memory controller sees a uniform 1Rx8 configuration across every channel.

Questions about this item

Will DDR4-3200 run at full speed in a ThinkMate HDX-XN24-52S3 server?

The kit is rated PC4-25600 at 3200 MT/s and will operate at that speed if the server memory controller and BIOS support DDR4-3200; otherwise it down-clocks to the highest supported JEDEC rate.

Does the registered ECC design limit bandwidth or latency compared with unbuffered modules?

Registered DIMMs add one clock cycle of address buffering, which slightly increases latency but allows the platform to populate more slots without signal degradation, so total capacity scales higher.

Do the 288-pin RDIMMs fit standard DDR4 server DIMM slots without a heat spreader?

Yes, each 8 GB module uses the standard 288-pin RDIMM form factor and has no heat spreader, so it seats directly in any DDR4 RDIMM slot with normal retention clips.
