Welcome to the Cutting-Edge of Performance: Push the limits of your system like never before with DDR5 memory, unlocking even faster frequencies, greater capacities, and better performance.
Do it All, and Do it Faster: As modern CPUs feature more and more cores, the unprecedented speed of DDR5 ensures your high-end CPU gets data quickly, enabling faster processing, rendering, and buffering than ever before.
12 Ultra-Bright CAPELLIX RGB LEDs: Each module is lined with 12 individually addressable LEDs to illuminate your PC with spectacular customizable lighting and low power consumption.
Patented CORSAIR DHX Cooling: Keeps DDR5 temperatures down by cooling both the ICs and the ground plane of the PCB itself with its own dedicated heatspreader, for high performance even under extreme loads.
Onboard Voltage Regulation: Reliable voltage at high frequencies enables easier, finely controlled overclocking through CORSAIR iCUE software than previous generation motherboard control.

RAM First Word Latency Table (nanoseconds)

Latency is measured in nanoseconds, which is a combination of frequency and CAS. Both frequency increases and latency decreases result in better system performance (when latency is the same, always prefer higher frequency if possible).

CAS (clock cycles) Lower latency means faster memory.

Distribution of First Word Latencies for Similar RAM Modules

The histogram below shows the distribution of first word latencies (in nanoseconds) for all RAM modules of the same DDR type and frequency in our database. Each bar represents the number of modules that fall within a specific latency range. The highlighted bar indicates the latency of the currently selected RAM module.
