System-specific DDR5 ECC kit

This 32 GB kit contains two 16 GB DDR5 RDIMMs built for ThinkMate tower servers. Registered ECC operation protects data integrity in mission-critical workloads. The modules run at 4800 MT/s with CL40 latency at 1.10 V.

288-pin registered form factor

Each stick uses a 1Rx8 organisation without a heat spreader to fit dense server DIMM slots. Registered buffering reduces electrical load on the memory controller for stable operation under sustained load. Major OEM DRAM from Samsung, Micron or Hynix underpins long-term reliability.

Upgrade from lower-capacity RDIMMs

Replacing smaller registered ECC modules with this 32 GB kit doubles usable memory per channel for virtualisation or database tasks. The jump is worthwhile when current capacity limits concurrent VMs or large in-memory datasets. Buyers needing unbuffered UDIMMs or non-ECC memory cannot use this product.

Questions about this item

What DDR5 standard does the PC5-38400 rating represent for these modules?

PC5-38400 is the JEDEC designation for DDR5 4800 MT/s, which is the rated data rate of this kit.

Will these 288-pin RDIMMs fit a standard DDR5 UDIMM desktop slot?

No, RDIMMs are longer and keyed differently; they require a server or workstation motherboard with registered DIMM slots.

Does the 1Rx8 rank layout require any specific BIOS setting on the ThinkMate TWX-XS8 servers?

Install the modules in the channels indicated by the server manual; the registered buffer and ECC are initialised automatically at POST.
