384GB DDR5-4800 ECC RDIMM kit for Thinkmate

This 384GB kit contains six 64GB DDR5-4800 registered DIMMs with ECC and CL40 latency. The modules run at 1.10V and use a 2Rx4 organisation on 288-pin connectors. They are built for the Thinkmate RAX-XS4-21S4 rackmount server.

Suited for the Thinkmate RAX-XS4-21S4 server

This memory fits the Thinkmate RAX-XS4-21S4 platform that requires registered ECC DDR5 RDIMMs. Systems needing unbuffered UDIMMs, non-ECC modules, different speeds or lower capacities should choose other memory.

288-pin DDR5 RDIMM form factor

The kit uses the 288-pin DDR5 RDIMM form factor with registered buffering and ECC. Only motherboards with DDR5 RDIMM slots supporting 2Rx4 modules at 4800 MT/s can accept these DIMMs.

Questions about this item

What type of server motherboard is required to install this 384 GB DDR5 4800 CL40 2Rx4 ECC RDIMM kit?

The modules are built for the Thinkmate RAX-XS4-21S4 rackmount server and require a DDR5-compatible motherboard that supports 288-pin registered ECC RDIMMs at 1.1 V.

Will these six 64 GB modules run at their rated 4800 MT/s speed if the server currently uses slower DDR5 RDIMMs?

The kit is rated DDR5-4800 (PC5-38400) CL40; the server memory controller will set the final speed to the lowest common denominator among all installed DIMMs.

How can I confirm the full 384 GB capacity is recognised and ECC is active after installation?

Enter the system BIOS or UEFI and check the memory information screen — it should show 384 GB total and report ECC as enabled or active.
