Corsair Vengeance 16GB DDR5 SO-DIMM kit

This Corsair Vengeance kit supplies 16GB of DDR5 laptop memory as two 8GB modules. The 262-pin SO-DIMM format fits compatible Intel Core 12th Gen and newer laptops, NUCs, and AMD Ryzen PRO 6000 series machines. A built-in heat spreader helps manage thermals during sustained workloads.

Suits DDR5 laptop upgrades.

Owners of supported Intel or AMD DDR5 laptops and small-form-factor PCs can install this kit with only a screwdriver. The modules automatically run at their rated speed on compatible systems without BIOS changes. Systems that require a different memory generation, pin count, or voltage will not accept these modules.

4800 MT/s speed with CL40 latency

The decisive specification is the DDR5 4800 (PC4 38400) rating paired with CAS latency 40 and 40-40-40-77 timings at 1.10V. This combination determines whether the memory matches your platform's supported data rate and latency window. Verify your laptop's qualified vendor list against these exact figures before purchasing.

Questions about this item

Will the CL40 latency become a bottleneck during long gaming sessions?

CL40 is the rated CAS latency for these DDR5 4800 modules; sustained gaming workloads run at this timing without additional latency penalties.

Does the 1.10V voltage keep thermals manageable in a compact laptop chassis?

The 1.10V operating voltage is standard for DDR5 SO-DIMMs and reduces power draw compared to previous generations, helping thermals in thin laptops.

My laptop has 262-pin DDR5 slots — is a screwdriver the only tool needed for installation?

Yes, the 262-pin DDR5 SO-DIMM form factor fits standard slots and the manufacturer notes a screwdriver is typically the only tool required.
