192GB DDR5 ECC Registered kit

This V-color OC R-DIMM kit delivers 192GB across four 48GB modules running at DDR5 6400 CL32. It targets TRX50 workstation builders who need high-capacity registered ECC memory with an AMD EXPO profile for supported overclocking. Each module uses Hynix ICs on a 10-layer PCB tested with automated sorting equipment.

Registered DIMMs for TRX50 motherboards

The 288-pin registered design requires a motherboard with RDIMM support and a compatible Threadripper PRO 7000 series processor. Registered buffering reduces electrical load on the memory controller, allowing this 2Rx8 quad-channel population. The on-board PMIC manages power delivery at the specified 1.40V operating voltage.

EXPO profile and on-die ECC

The AMD EXPO profile configures the rated 6400MT/s speed and 32-39-39-102 timings without manual tuning. On-die ECC provides an additional error-correction layer alongside the module-level registered ECC. Heat spreaders are included on all four modules to assist thermal management under sustained workloads.

Questions sur cet article

At what CAS latency does the kit run when all four 48 GB modules operate at DDR5 6400?

The modules are rated CL32 at the full 6400 MT/s speed, with timings of 32-39-39-102.

How much power and heat should I expect from a 1.40 V DDR5 kit running continuously in a TRX50 workstation?

Operating at 1.40 V with on-board PMICs, the four registered DIMMs draw more power than standard JEDEC voltage; ensure your chassis airflow can handle the extra heat from sustained loads.

Which motherboard platform and CPU family are required to use the AMD EXPO profile on this memory?

The kit is validated for AMD TRX50 workstation motherboards paired with Threadripper PRO 7000 series processors.
