System-Specific DDR5 ECC RDIMM Kit

This 64GB kit contains two 32GB DDR5 4800 CL40 registered DIMMs built for the THINKMATE GPX-WS-740RTP7 workstation. Each module runs at 1.1V and uses a 2Rx8 organisation with on-die ECC for data integrity. The 288-pin form factor matches the platform’s DDR5 RDIMM slots exactly.

Compatibility Check Before Ordering

Verify that your workstation is the exact GPX-WS-740RTP7 model and that the motherboard accepts DDR5 registered ECC RDIMMs. Confirm the board has two free 288-pin slots and that the BIOS supports 4800 MT/s registered modules. Mixing with unbuffered or non-ECC memory will prevent the system from posting.

What the Kit Changes

Adding the matched pair populates two channels with identical 32GB ranks, enabling the workstation to address the full 64GB at the rated 4800 MT/s speed. Registered buffering reduces electrical load on the memory controller, while ECC corrects single-bit errors during sustained compute workloads. No heat spreaders are included, so airflow across the bare modules must be adequate.

Questions about this item

What comes in the NEMIX RAM 64GB kit and do I need to buy anything else to install it?

The kit contains two 32GB DDR5 4800 CL40 ECC RDIMM modules (2Rx8, 1.10V, 288-pin). No extra parts or accessories are required for installation in the compatible workstation.

Why is this memory sold as a 2x32GB kit instead of a single 64GB module?

The 2x32GB configuration populates two DIMM slots for dual-channel operation, delivering the full 64GB capacity at DDR5 4800 speed with CL40 latency and ECC registered reliability.

What does the DDR5 4800 CL40 rating mean for actual performance in the ThinkMate GPX-WS-740RTP7?

The modules run at 4800 MT/s with CAS latency 40 at 1.10V, providing registered ECC stability for server workloads while matching the workstation's supported memory speed and voltage.
