64 GB DDR5 4800 kit for 12th Gen Intel laptops

This 64 GB kit contains two 32 GB DDR5 4800 SO-DIMMs built for laptops that support DDR5 memory. The modules run at 1.10 V with CL40 latency and 40-39-39 timings. They target users upgrading 12th Gen Intel Core laptops for heavier multitasking, content creation or gaming workloads.

Sustained throughput with 4800 MT/s bandwidth

At DDR5 4800 the kit delivers PC5-38400 bandwidth that holds up during long rendering, compilation or virtualisation sessions. The 1.10 V operating voltage keeps thermals manageable inside thin chassis, while unbuffered non-ECC operation avoids the latency penalty of registered modules. CL40 timings remain stable across extended loads.

Replaces DDR4 or smaller DDR5 kits when capacity

The jump is worth it when 32 GB or 48 GB no longer fits active projects, virtual machines or large texture pools. Buyers tied to DDR4 platforms cannot use these modules; the 262-pin DDR5 keying is physically incompatible. Systems limited to lower maximum capacities will not recognise the full 64 GB.

Soalan tentang produk ini

Will the 1.10V DDR5 modules run cooler than DDR4 sticks during all-day workloads?

DDR5 operates at 1.10V, which is lower than DDR4 voltage, so the modules draw less power and generate less heat under sustained load.

Does my laptop need a DDR5-capable motherboard and 262-pin SO-DIMM slots to use this kit?

Yes, this kit is compatible only with DDR5-enabled laptops that have 262-pin SO-DIMM slots; it will not fit or work in DDR4 systems.

Can I mix these 4800 CL40 modules with slower DDR5 sticks already in my laptop?

Mixing speeds or timings forces all modules to run at the lowest common speed and loosest timings, so performance will drop to match the slower sticks.
