WRX90 Workstation Memory Kit

This 128 GB kit contains eight 16 GB DDR5 OC R-DIMM modules rated at 7200 MHz with CL34 timings. It is built for AMD Threadripper PRO 7000 series workstations on WRX90 motherboards and includes registered ECC operation with AMD EXPO profile support.

Installation Notes

Modules use the standard 288-pin DDR5 form factor and seat in the motherboard DIMM slots like any registered DIMM. The on-board RCD and PMIC micro-heatsinks add height, so confirm that your CPU cooler or chassis clearance accommodates taller sticks before fitting all eight slots.

Pre-Purchase Checks

Verify that your motherboard is a WRX90 model qualified for DDR5 7200 operation with 1Rx8 registered ECC modules at 1.4 V. Ensure the BIOS revision listed by the board vendor supports the AMD EXPO profile for this speed and capacity configuration.

Questions about this item

How can I confirm the AMD EXPO profile is active and the kit runs at 7200MHz CL34 after installation?

Enter the BIOS on your WRX90 workstation and enable the AMD EXPO profile; the memory should then report DDR5 7200 speed with 34-45-45-112 timings at 1.4V.

What is included in the box and are any extra parts needed for installation?

The package contains eight 16GB 288-pin DDR5 RDIMM modules with integrated heat spreaders and patented RCD and PMIC micro-heatsinks; no additional components are required for WRX90 motherboards.

Should I choose this 128GB 7200MHz CL34 kit or a different capacity for my Threadripper PRO 7000 workstation?

This 128GB kit (16GB x 8) targets maximum supported capacity on WRX90 boards with AMD EXPO overclocking; select it when you need the full eight-channel population at 7200MHz CL34.
