32GB DDR5 4800 ECC RDIMM for ThinkMate Servers

This 32GB DDR5 module runs at 4800MHz with CL40 latency and 1.10V operation. It uses a 2Rx8 registered ECC design on a 288-pin form factor. The module is validated for ThinkMate GPX-QH12-12E4-2GPU GPU-optimised servers.

DDR5 4800 registered ECC limits

Registered DDR5 at 4800MHz requires a motherboard with RDIMM slots and a memory controller that supports ECC error correction. Unbuffered consumer boards cannot accept this module. The 2Rx8 organisation and CL40 timing are fixed by the JEDEC PC5-38400 standard for this speed grade.

Check your ThinkMate server before ordering

Verify the server manual lists DDR5 4800MHz RDIMM support and the maximum capacity per slot. Confirm the board has free 288-pin RDIMM slots and that the BIOS revision supports 32GB registered modules. ECC and registered functions must be enabled in the platform firmware.

Questions about this item

Should I pick the 32GB single module or add multiple sticks for the THINKMATE GPX-QH12-12E4-2GPU?

The module is sold as a single 32GB stick; add more identical modules to reach the capacity your server board supports.

What does the 4800MHz CL40 rating deliver in the THINKMATE server?

It runs at DDR5 4800 with CAS latency 40 at 1.10V, providing ECC error correction and registered buffering for stable server operation.

How does the PC5-38400 288-pin RDIMM interface limit performance?

The 288-pin DDR5 RDIMM slot caps the module to the PC5-38400 standard, so the stick cannot exceed its rated 4800MHz speed.
