Corsair Vengeance LPX CMK64GX4M4D3600C18 64GB (4×16GB) DDR4 3600 CL18 desktop RAM

Capacity and kit layout

This kit delivers 64GB of DDR4 memory across four 16GB modules, giving a full four-channel population for desktop platforms that support it. The 288-pin form factor fits standard consumer motherboards and the black anodized aluminum heatspreader keeps the modules low enough for most small-form-factor builds at 34mm tall.

DDR4 3600 practical limits

The memory runs at DDR4 3600 (PC4 28800) with a rated voltage of 1.35V and timings of 18-22-22-42, which is the highest JEDEC-defined speed tier for DDR4 before overclocking headroom begins. Intel XMP 2.0 support allows the rated profile to be applied with a single BIOS setting, but stability at this frequency still depends on the memory controller quality of the specific CPU and the motherboard topology.

CAS latency as the deciding spec

The CL18 CAS latency is the single figure that determines whether this kit matches the latency budget of a given workload; lower latency at the same frequency yields snappier response in latency-sensitive tasks, while higher latency may be acceptable for throughput-oriented applications. Hand-sorted chips and a high-performance PCB provide overclocking headroom, but the rated CL18 at 3600MT/s remains the baseline specification to evaluate against system requirements.
