32 GB DDR5 ECC RDIMM kit

This 32 GB kit contains two 16 GB DDR5 4800 modules built to the PC5-38400 standard. Each stick is a 288-pin registered DIMM with ECC and a 1Rx8 layout running at 1.10 V and CL40 latency. It is validated for the Thinkmate GPX-QH12-12E4-2GPU server platform.

Suited for Thinkmate GPX-QH12-12E4-2GPU

The modules are qualified for the Thinkmate GPX-QH12-12E4-2GPU GPU-optimised server and similar Thinkmate systems that accept DDR5 4800 ECC RDIMM memory. They are not suitable for desktops, laptops or workstations that require unbuffered non-ECC DDR5 or earlier DDR generations. Buyers who need higher capacities per module or different speeds should look elsewhere.

Check DDR5 RDIMM slot count and population rules

Verify that your Thinkmate server has free 288-pin DDR5 RDIMM slots and that the motherboard supports 1Rx8 registered modules at 4800 MT/s. Confirm the maximum memory per channel and total capacity allowed by the specific CPU configuration. Ensure the system BIOS is current enough to recognise DDR5 4800 ECC registered DIMMs.

Questions about this item

Does my server need DDR5 RDIMM slots that support ECC and registered modules to use this 32GB kit?

Yes, this kit requires a motherboard with 288-pin DDR5 RDIMM slots that accept ECC registered memory running at 1.1V.

Will these CL40 4800MHz modules run correctly alongside any existing DDR5 4800 ECC RDIMM sticks I keep installed?

They will operate at the same 4800MHz speed and CL40 timing as matching DDR5 ECC RDIMM modules already in the system.

How can I confirm the kit is detected as 32GB of ECC registered memory after installation?

Check the BIOS or OS memory report — it should show 32GB total, DDR5 4800, ECC enabled, and registered (RDIMM) mode.
