  • Low 1.10 V operation improves energy efficiency
  • CL40 timing tuned for responsive performance
  • 262-pin SO-DIMM fits compatible laptop slots

Ideal DDR5 upgrade for Intel 600 Series laptops

This 32GB kit contains two 16GB SO-DIMMs built to the DDR5 4800 standard. Unbuffered, non-ECC modules run at 1.10V and carry a CL40 latency rating. The matched pair is designed for dual-channel operation in compatible notebooks and small-form-factor systems.

Steady throughput at rated voltage

Each module operates at the JEDEC DDR5 4800 frequency with 40-39-39-76 timings without requiring a voltage increase. The screened ICs and G.SKILL binning process aim to keep performance consistent during extended workloads rather than only in short bursts. Mixing this kit with other memory is not supported and can cause instability.

262-pin DDR5 SO-DIMM form factor

The 262-pin connector is the physical interface that determines fitment in a laptop slot. DDR5 modules are mechanically incompatible with DDR4 sockets, so this kit will only install in systems built for DDR5 SO-DIMMs.

Questions about this item

How much power does the 1.10V DDR5 kit draw compared with older memory when the laptop runs all day?

The modules operate at 1.10V, which is the standard DDR5 voltage and lower than the 1.2V used by DDR4, so sustained power draw is reduced.

What slot type must my laptop already have for these 262-pin modules to fit?

Your laptop needs a DDR5 SO-DIMM slot; the 262-pin keying is physically different from DDR4 and the modules will not seat in an older socket.

Can I add this dual-channel kit alongside an existing 16 GB stick without stability issues?

The manufacturer states not to mix memory kits; combining this matched 2 x 16 GB set with other modules can cause instability or failure to boot.
