Know before you buy
This kit is tested across multiple DDR4 motherboards for broad compatibility, but you should verify that your motherboard's QVL (Qualified Vendor List) supports 3866MHz speeds. Ensure your BIOS is updated to the latest version to guarantee stability at this frequency.
This kit supports XMP 2.0, which makes achieving the rated speed straightforward. Simply enter your motherboard's BIOS settings and enable the XMP profile to automatically configure the voltage and timings for peak performance.
No, this memory does not support ECC (Error Correction Code). It is designed specifically for high-performance gaming and enthusiast desktop builds that utilize standard non-ECC DDR4 memory.
The patented DHX cooling system uses a custom PCB and machined aluminum heat sinks to pull heat away from the memory ICs efficiently. This ensures the modules remain stable and reliable even when pushed to high speeds during intensive gaming or heavy workloads.
Yes, the modules feature white LED lighting that can be managed via CORSAIR iCUE software. Additionally, the top light bar is removable, allowing you to swap it out with optional light bar kits to better match your system's aesthetic.
If your system fails to post at the XMP speed, it is likely due to motherboard or CPU memory controller limitations. You can manually adjust the speed to a lower frequency in the BIOS or ensure your CPU supports high-speed memory profiles.
