Speed DDR5 7000 (PC5 56000)

  • 128 GB capacity across eight 16 GB modules for large workloads
  • DDR5 7000 MHz speed with CL34 latency for fast response
  • ECC registered design protects data integrity under heavy load
  • AMD EXPO profile enables one-click overclocking on WRX90 platforms
  • Patented RCD and PMIC micro-heatsinks lower temperatures by 30-40%

Built for WRX90 workstations

This 128 GB kit delivers eight 16 GB DDR5 registered DIMMs tuned to 7000 MHz with CL34 latency. It targets Threadripper PRO 7000 series systems that require ECC integrity at overclocked speeds. The AMD EXPO profile activates the rated frequency without manual tuning. Builders who need more capacity or non-registered modules should look elsewhere.

Registered design with micro-heatsinks

Each module uses a 288-pin RDIMM layout and 1Rx8 Hynix ICs on a 10-layer PCB. Patented copper-alloy micro-heatsinks cover the RCD and PMIC, lowering their temperature by 30 to 40 percent versus bare sticks. The 1.4 V operating voltage supports sustained high-frequency operation. Systems without WRX90 chipset support cannot use this memory.

EXPO profile and validated ICs

The bundled AMD EXPO profile sets 7000 MHz, CL34-42-42-102 timings and 1.4 V automatically in compatible BIOSes. Factory auditing and automated sorting of every Hynix die aim to reduce early-life failures. No extra software utilities or RGB control applications are included. Users who prefer manual voltage scaling or lower-voltage JEDEC profiles will not find those options pre-configured.

Questions about this item

What DDR5 speed and peak transfer rate does the EXPO profile on these 128GB R-DIMMs target?

The kit runs at 7000MHz with a PC5-56000 rating when the AMD EXPO profile is enabled.

What physical clearance and slot count do the 288-pin modules with the RCD and PMIC micro-heatsinks require?

Eight 288-pin DDR5 RDIMM slots are needed; the copper-alloy micro-heatsinks on the RCD and PMIC add height, so verify CPU-cooler clearance.

How do I install the eight 16GB sticks so the WRX90 motherboard recognises the full 128GB at 7000MHz CL34?

Populate all eight channels in the order the board manual specifies, enable the AMD EXPO profile in BIOS, and confirm 1.4V is applied; skipping the EXPO step leaves the kit at JEDEC defaults.
