WRX90 OC R-DIMM 128GB kit

This 128GB kit contains eight 16GB DDR5 registered DIMMs rated at 5600MHz with CL36 timings. It is built for AMD Threadripper PRO 7000 series workstations using WRX90 motherboards and runs at 1.25V with an AMD EXPO profile.

Suited for ECC workstations, not standard PCs

The registered ECC design targets data integrity on WRX90 platforms. Builders using consumer Ryzen CPUs or unbuffered memory boards should look elsewhere because this kit requires registered DIMM support and the WRX90 chipset.

Patented RCD and PMIC micro-heatsinks included

Each module ships with copper-alloy micro-heatsinks on the RCD and PMIC to lower operating temperatures by 30 to 40 percent versus bare modules. No additional software or accessories are bundled beyond the EXPO profile stored on the DIMMs.

Questions about this item

Do I need a WRX90 motherboard with 288-pin DDR5 slots to install these 8 registered modules?

Yes, the kit is built for AMD WRX90 workstation boards that accept 288-pin DDR5 RDIMMs and provides eight 16GB sticks for a total of 128GB.

Can I mix these 5600MHz CL36 ECC RDIMMs with slower registered DDR5 already in my system?

Mixing registered ECC modules of different speeds or timings is not recommended; the memory controller will default to the lowest common settings and stability cannot be assured.

How can I confirm the EXPO profile is active after I populate all eight slots?

Enter the BIOS and verify the memory frequency reads 5600MHz with timings of 36-38-38-80 at 1.25V, which shows the AMD EXPO profile has been applied.
