128GB DDR5 4800 ECC RDIMM Kit

This kit supplies 128GB of DDR5 4800 registered ECC memory in eight 16GB modules. It is built for the Thinkmate RAX-QE12 rackmount server and uses 288-pin RDIMMs with a CL40 latency and 1.1V operating voltage.

Suited for Thinkmate RAX-QE12 upgrades

It suits administrators expanding the RAX-QE12 to its full 128GB capacity with matched, registered ECC modules. It is not for workstations or laptops that require unbuffered UDIMMs, nor for any system that cannot accept registered DDR5 RDIMMs.

Registered ECC RDIMM form factor

The registered ECC RDIMM design provides error correction and signal buffering essential for server stability. Buyers must confirm their platform supports DDR5 registered memory before purchasing, as unbuffered boards will not accept these modules.

Questions about this item

My Thinkmate RAX-QE12 has eight DIMM slots — can I install all eight 16 GB modules at once?

Yes, the kit provides eight 16 GB RDIMMs for a total of 128 GB, matching the eight-slot layout of the RAX-QE12.

If I keep my existing DDR5 4800 RDIMMs and add this kit, will the system run at CL40?

All modules in this kit are CL40; mixing with other CL40 DDR5 4800 RDIMMs will maintain that latency.

After seating the modules, how can I confirm the server sees the full 128 GB at 4800 MT/s with ECC active?

Check the BIOS memory summary or run a tool such as dmidecode — it should report 128 GB, 4800 MT/s, registered ECC, 1.10 V, CL40.
