NEMIX 64 GB DDR4 3200 Kit

This NEMIX RAM kit delivers 64 GB of DDR4 3200 memory in a matched pair of 32 GB modules. It is built for owners of the listed ASUS Prime motherboards who need a straightforward capacity increase without enabling ECC or registered operation. The modules are unbuffered and non-ECC, matching the standard desktop DIMM slots on those boards.

Thermals and power at 1.2 V

Each module runs at the standard 1.20 V DDR4 voltage, so power draw stays within normal desktop limits and no additional cooling is required beyond typical case airflow. The sticks have no heat spreader, keeping the profile low for tight CPU cooler clearances. Under normal workloads the memory operates silently with no active components.

What the kit includes

The package contains two 288-pin UDIMMs rated at PC4-25600 with CL22 latency and a 2Rx8 organisation. No software, drivers or extra accessories are bundled; the upgrade is complete once the modules are seated in the motherboard slots. Builders who need ECC, registered DIMMs or a different capacity should look elsewhere.

Questions about this item

How do I install the 288-pin DDR4 UDIMM modules in my ASUS motherboard, and what step is often missed?

Align the notch on each 32 GB stick with the slot key, press straight down until both side clips click, then verify in BIOS that both modules report 3200 MT/s and CL22 timings.

What maintenance or replacement will the 2Rx8 DDR4 kit need over its lifetime?

No scheduled maintenance is required; keep the gold contacts clean and ensure the CPU cooler clears the modules — if a stick ever fails, the lifetime replacement warranty covers it.

What limit appears first when the 1.2 V DDR4 3200 kit runs sustained heavy workloads?

The CL22 latency and lack of a heat spreader mean the modules will hit thermal throttling before bandwidth becomes a bottleneck.
