  • On-board PMIC manages power for consistent performance

TRX50 workstation memory kit

This 64 GB kit uses four 16 GB DDR5 registered DIMMs built for AMD Threadripper PRO 7000 series workstations on TRX50 motherboards. ECC and AMD EXPO profiles give data integrity and one-click overclocking for professional workloads.

64 GB capacity and CL32 headroom

At 6400 MT/s with 32-39-39-102 timings and 1.40 V, the kit handles multi-threaded rendering, simulation and virtualisation workloads that benefit from high bandwidth and error correction. Four single-rank modules leave no spare slots on typical eight-slot TRX50 boards for further expansion.

DDR5 registered DIMM limits

Registered signalling and on-board PMIC stabilise heavy loads, while on-die ECC adds a second correction layer for reliability. The 288-pin DDR5 interface doubles DDR4 channel bandwidth, but speed and latency gains depend on CPU memory-controller quality and motherboard trace layout.

Questions about this item

Will these 6400 CL32 modules run at rated speed on a TRX50 board with older DDR5 already installed?

The kit uses AMD EXPO on TRX50 workstations; mixed DIMM populations depend on the motherboard's memory topology and BIOS revision, so enable EXPO after install and verify stability.

How do I confirm the ECC registered function is active after boot?

Check the BIOS memory information screen for ECC status and registered mode, or run a memory diagnostic that reports ECC correction events during test passes.

Does the box include only the four 16 GB DIMMs or any extra accessories?

The package contains the four 288-pin DDR5 RDIMMs with heat spreaders; no cables, brackets or additional cooling parts are supplied.
