AMD TRX40 64GB DDR4 Kit

This NEMIX RAM kit delivers 64GB of DDR4 memory across two 32GB unbuffered UDIMM modules. Rated at 3200MT/s with CL22 latency, it operates at the standard 1.2V. The modules use a 2Rx8 organisation and fit 288-pin slots on compatible AMD TRX40 chipset motherboards.

Builders upgrading TRX40 workstations

Suitable for professionals expanding memory capacity on qualified ASUS motherboards using the AMD TRX40 platform. Buyers needing ECC error correction or registered modules for server-grade stability should look at different memory lines. Systems limited to lower speeds or different pin counts cannot use this kit.

2Rx8 rank organisation decides fit

The dual-rank 2Rx8 layout determines how the memory controller addresses each module. Some AMD TRX40 motherboards populate slots differently depending on rank count, so verify the board's qualified vendor list before purchase. This single attribute governs whether the full 64GB capacity will initialise correctly.

Questions about this item

Will this DDR4 3200 kit run alongside my existing DDR4 modules if they share the same voltage?

The kit operates at 1.20 V, the standard voltage for DDR4. Mixing speeds is possible but the system will run all modules at the speed of the slowest kit and at the loosest timings present.

How can I verify the 3200 MT/s speed and CL22 timings are active after installation?

Open the BIOS or UEFI and check the memory frequency and CAS latency readings, or use a tool such as CPU-Z to confirm the modules report DDR4 3200 with CL22.

Does the 64 GB kit include only the two 32 GB UDIMMs, or are heat spreaders and cables also supplied?

The package contains only the two 288-pin 32 GB unbuffered non-ECC UDIMMs; no heat spreaders, cables or other accessories are included.
