Workstation Memory for TRX50 Platforms

This 64 GB kit uses four 16 GB DDR5 registered DIMMs built with Hynix ICs on a 10-layer PCB. Each module runs at 6800 MT/s with CL34-46-46-92 timings at 1.40 V. On-die ECC and registered buffering protect data integrity for Threadripper PRO 7000 series workstations. The kit targets professionals who need stability under sustained loads.

AMD EXPO Profile Enables One-Click Overclocking

The bundled AMD EXPO profile stores the 6800 MT/s frequency and tight timings in the module SPD. Selecting it in BIOS applies the rated speed, voltage and latency without manual tuning. This saves configuration time and reduces the risk of unstable manual settings. Builders who prefer custom voltages or lower frequencies can still adjust values manually.

DDR5 Dual-Channel Architecture Doubles Sub-Channel

Each DIMM presents two independent 40-bit sub-channels, doubling burst throughput compared to DDR4. The on-board PMIC regulates power locally for cleaner signalling at 6800 MT/s. Registered buffering adds one clock cycle of command latency, a fixed trait of RDIMM topology. Systems without TRX50 chipset support cannot use these modules.

Questions about this item

Will the Hynix ICs on these R-DIMMs need replacement under normal server workloads?

The modules use Hynix ICs on a 10-layer PCB with automated sorting and rigorous testing, so they are built for long-term reliability without scheduled IC replacement.

Does the CL34-46-46-92 timing limit sustained throughput before the 6800 MT/s speed does?

At DDR5 6800 the CAS latency is 34 cycles with 46-46-92 timings; the rated speed and latency are specified together, so neither is singled out as the first bottleneck.

How much heat does the 1.4 V registered design produce when running all day in a TRX50 workstation?

The kit runs at 1.40 V with an integrated heat spreader and on-board PMIC for efficient power delivery, keeping thermals controlled during continuous operation.
