ThinkMate DDR5 4800 ECC RDIMM 256GB Kit

This registered DDR5 memory kit provides 256GB across two 128GB modules for ThinkMate RAX-XS4-21S4 rackmount servers. It operates at 4800MHz with CL40 latency and 1.10V voltage. ECC and registered buffering protect data integrity in mission-critical workloads. The dual-rank 4Rx4 organisation uses major OEM Samsung, Micron or Hynix chips.

Suited for ThinkMate servers requiring registered

The kit fits administrators expanding capacity in the validated RAX-XS4-21S4 platform where registered DIMMs are mandatory. Builders needing unbuffered UDIMMs, non-ECC modules or speeds above 4800MHz should look elsewhere. Systems limited to lower densities than 128GB per slot cannot use these modules. Laptop, desktop or consumer motherboards are not supported.

Registered ECC with 4Rx4 organisation decides

The registered buffer and on-die ECC require a server chipset that explicitly supports RDIMM signalling. The 4Rx4 rank structure demands memory-controller support for quad-rank addressing. Without both features in the host firmware the modules will not initialise. Verify the ThinkMate service manual before purchase.
