64GB DDR5 ECC RDIMM Kit

This NEMIX RAM kit provides 64GB of DDR5 ECC registered memory in two 32GB modules. It runs at 4800MHz with CL40 latency and operates at 1.1V. The 288-pin RDIMM modules use 2Rx8 organisation and are validated for ThinkMate GPX-QH12-12E4-2GPU servers.

For ThinkMate server upgrades only

This memory suits administrators upgrading the specified ThinkMate GPU-optimised server with registered ECC DDR5. It will not fit desktop motherboards, laptops, or systems that require unbuffered UDIMM modules or a different DDR generation.

Check DDR5 RDIMM slot count and population rules

Before ordering, confirm your server has enough free 288-pin DDR5 RDIMM slots for two modules. Verify the motherboard qualification list for 2Rx8 4800MHz registered ECC at 1.1V and review the manual for required slot-filling order.

Questions about this item

Does the THINKMATE GPX-QH12-12E4-2GPU server need a DDR5 RDIMM motherboard to use these 4800 CL40 1.1V modules?

Yes, the kit is built for DDR5 RDIMM slots on the THINKMATE GPX-QH12-12E4-2GPU server; the 288-pin 1.1V design will not fit older DDR generations.

Can I mix these 2Rx8 32GB sticks with 1Rx4 or 2Rx4 modules already installed in the same server?

The kit uses 2Rx8 organisation; matching rank and width is recommended for stability, so check the server manual before mixing different rank configurations.

How do I confirm the memory is running at the rated 4800 MT/s with ECC active after installation?

Enter BIOS or use a tool like dmidecode to verify speed shows 4800 MT/s, CAS latency reads CL40, and ECC status reports enabled on all 64GB.
