ThinkMate XF4-24S3 Compatible DDR4 RDIMM Kit

This 384GB kit contains six 64GB DDR4 3200 registered ECC modules built for the ThinkMate XF4-24S3 workstation. The 288-pin RDIMM form factor fits server-grade motherboards that require registered memory. It targets IT professionals upgrading mission-critical systems with validated compatibility.

DDR4 3200 Registered ECC Speed and Rank Constraints

The PC4-25600 standard caps transfer rates at 3200 MT/s with a CAS latency of 22. Each module uses a 4Rx4 organisation, so the memory controller must support quad-rank registered DIMMs. Registered buffering adds one clock cycle of address latency compared with unbuffered modules.

384GB Total Capacity in Six Slots

The kit delivers 384GB across six 64GB sticks, requiring six free DDR4 RDIMM slots on the target board. Systems with fewer than six slots or a lower per-slot limit cannot use the full kit. Buyers needing a smaller increment should select a lower-capacity kit.

Questions about this item

Should I buy the 6 x 64 GB kit or look for a different capacity?

The kit provides 384 GB total across six 64 GB modules, matching the maximum supported configuration for the compatible THINKMATE XF4-24S3 workstation.

What does the DDR4 3200 PC4-25600 rating mean for actual throughput?

The modules run at 3200 MT/s, delivering up to 25600 MB/s of peak bandwidth per channel when installed in a supported server platform.

How does the 288-pin RDIMM interface limit what I can install?

The 288-pin registered DIMM form factor fits only DDR4 RDIMM slots; it cannot be used in UDIMM, SO-DIMM or DDR5 sockets.
