Corsair Vengeance DDR4 SO-DIMM 3000MHz CL18 - 16GB (2x8GB)

Corsair Vengeance DDR4-3000 SO-DIMM runs at 3000MHz CL16-18-18-39 at 1.2V. Like the 2933MHz variant, this is a niche speed tier. 3000MHz never became a standard OEM laptop configuration, and most systems that support speeds above 2666MHz jump straight to 3200MHz.

Overclocked SO-DIMM

DDR4-3000 exceeds the JEDEC standard memory speeds for most laptop platforms, so this kit relies on the system's ability to auto-detect and run above 2666MHz. Not all laptop BIOS implementations support non-standard speed tiers. The SPD profile falls back to 2666MHz at 1.2V on systems that don't support 3000MHz, so the kit won't fail to boot, it just won't run at rated speed.

Performance Context

At CL16/3000MHz, effective latency is about 10.7ns, slightly better than CL18/2666MHz (~13.5ns) and comparable to CL18/3200MHz (~11.3ns). The tighter CL16 timings help close the gap with 3200MHz kits despite the lower frequency. Available in kits up to 32GB (2x16GB). Non-ECC, unbuffered, 260-pin SO-DIMM. Limited lifetime warranty.

Best for: Systems that can run above 2666MHz but where you want tighter timings than a 3200MHz CL22 kit offers. Mini-ITX builds and NUCs where latency matters more than raw bandwidth.

Avoid if: Your system supports 3200MHz. DDR4-3200 kits are more widely available and validated. Or if your laptop BIOS doesn't support non-standard memory speeds, in which case this will just run at 2666MHz anyway.
