Know before you buy
The patented DHX cooling system is designed to pull heat away from the memory ICs and through the PCB, ensuring the modules remain stable and reliable even during high-performance overclocking sessions.
No, you do not need to manually adjust settings. This kit supports XMP 2.0, which allows you to enable the rated 4000MHz speed automatically through your motherboard's BIOS settings.
While the DHX heat spreaders provide excellent passive cooling, the included active fan is recommended if you are pushing the system to its limits or working in a case with limited airflow to maintain optimal temperatures.
This kit is specifically validated for use with Intel 300, 400, and 500 series chipsets, as well as the AMD TRX40 platform. Please verify your motherboard's QVL (Qualified Vendor List) to ensure full compatibility with the 4000MHz speed profile.
The modules feature subtle white LED lighting that provides a clean, professional aesthetic. You can monitor temperatures and manage the lighting integration through the CORSAIR LINK software.
The SPD speed of 2133MHz is the default, safe speed the memory runs at upon first installation. The 4000MHz tested speed is the high-performance profile that you activate via XMP to achieve the full potential of the kit.
