Kit capacity and audience

This 32GB kit contains four 8GB DDR4 modules rated at 3200 MT/s with CL16 timings. It targets enthusiasts and builders who want a matched quad-channel set for high-performance desktop workloads.

Thermals noise and power

Each module runs at 1.35V and uses an anodized aluminium low-profile heatspreader to dissipate heat without active cooling. The design adds no fan noise and keeps power draw low during sustained operation.

Build fit and clearance

The low-profile heatspreader clears most large air coolers and leaves room for tight component layouts. AMD X399 compatibility is confirmed, and the unbuffered 288-pin form factor fits standard desktop DIMM slots.

Questions about this item

How do I install the 288-pin modules in the four slots?

Align the notch on each stick with the slot key, press down evenly until both retention clips click, then repeat for all four modules.

What maintenance or replacement will the anodized aluminum heat spreader need later?

The heat spreader is passive and requires no replacement; occasional dust removal with compressed air keeps thermal performance consistent.

What limit appears first during sustained heavy workloads at 3200 MT/s and 1.35 V?

The CAS latency of 16-18-18-36 sets the timing floor; prolonged loads stay within this envelope as long as airflow clears the low-profile heatsink.
