Speed DDR5 7200 (PC5 57600)

  • ECC registered design protects data integrity on critical workloads
  • 7200 MT/s DDR5 speed with CL34 latency accelerates workstation throughput
  • 256 GB across eight 32 GB modules maximises Threadripper WRX90 capacity
  • Patented RCD and PMIC micro-heatsinks lower chip temperatures by 30 to 40 percent
  • AMD EXPO profile enables one-click overclocking at 1.4 V

V-color WRX90 OC R-DIMM 256GB Kit

This 256GB kit contains eight 32GB DDR5 registered DIMMs rated at 7200 MT/s with CL34 timings. It targets professionals building AMD Threadripper PRO 7000 series workstations on WRX90 motherboards who need maximum capacity with on-die ECC protection. The modules run at 1.4V and expose an AMD EXPO profile for one-click overclocking.

Registered 288-Pin Design With Micro-Heatsinks

Each stick uses a 10-layer PCB populated with SK Hynix ICs in a 2Rx8 configuration. Patented copper-alloy micro-heatsinks cover the RCD and PMIC components, lowering their temperatures by roughly 30 to 40 percent compared with bare modules. The registered buffer reduces electrical load on the memory controller, a requirement for stable operation at this density and speed.

AMD EXPO Profile And Tested Reliability

The bundled EXPO profile configures 34-45-45-112 timings automatically on compatible WRX90 boards, removing manual tuning. Every IC passes automated sorting and the finished modules undergo rigorous validation on a 10-layer PCB, ensuring consistent quality across all eight sticks in the kit.

Questions about this item

What DDR5 speed and CAS latency does this WRX90 OC R-DIMM kit run at with the AMD EXPO profile?

The kit operates at DDR5 7200 with CL34 timings (34-45-45-112) when the AMD EXPO profile is enabled in the BIOS.

What physical slot type and pin count do these modules require on the motherboard?

Each module is a 288-pin DDR5 RDIMM, so the motherboard must provide 288-pin DDR5 RDIMM slots.

How are the patented RCD and PMIC micro-heatsinks installed, and what mistake should be avoided?

The micro-heatsinks come pre-attached to the RCD and PMIC; do not remove them, as they are essential for cooling those components at 1.4 V operation.
