ThinkMate DDR4 3200 ECC RDIMM Kit

This 256 GB kit contains two 128 GB registered DDR4 modules built for ThinkMate servers and workstations. ECC and registered buffering protect data integrity in mission-critical workloads. The CL22 latency and 1.2 V operation suit enterprise memory controllers. IT teams specify this kit for qualified ThinkMate platforms.

DDR4 3200 Registered ECC Limits

DDR4 3200 registered ECC memory tops out at the PC4-25600 data rate defined by the JEDEC standard. Higher frequencies require down-clocking or a different memory generation. Four-rank 4Rx4 organisation increases electrical load per channel. Motherboard qualification lists determine maximum supported capacity per slot.

4Rx4 Rank Density Decides Fit

The 4Rx4 rank structure packs 128 GB into each 288-pin RDIMM. Systems qualified for dual-rank or single-rank modules may not initialise these sticks. Buyers must verify that their ThinkMate model explicitly supports 4Rx4 128 GB RDIMMs. Without that confirmation the kit will not post.

Questions about this item

Should I pick the 256 GB kit or look for a different capacity for my ThinkMate server?

This kit provides 256 GB total using two 128 GB modules, which is the only capacity offered for this part number.

What does the DDR4 3200 rating deliver once the modules are installed in a compatible ThinkMate system?

The modules run at 3200 MT/s with CL22 latency at 1.2 V, providing the rated PC4-25600 data rate for registered ECC workloads.

How does the 288-pin RDIMM interface limit performance in practice?

The 288-pin DDR4 RDIMM form factor with 4Rx4 organization and registered ECC operation defines the electrical and mechanical limits of the memory subsystem.
