Speed DDR5 5600 (PC5 44800)

CAS Latency CL46

  • Dual-channel kit doubles bandwidth with two 32GB modules
  • DDR5 5600 speed moves data at 5600 MT/s
  • Low 1.10V voltage reduces power draw and heat
  • CL46 latency keeps response tight for gaming and workloads
  • 262-pin SO-DIMM fits DDR5 laptop slots only

What this kit is

This Crucial DDR5 SO-DIMM kit delivers 64 GB across two 32 GB modules running at 5600 MT/s with CL46 latency at 1.10 V. It uses the standard 262-pin laptop form factor and is built for 12th Gen Intel Core mobile platforms that support DDR5 memory. The unbuffered, non-ECC design targets mainstream and high-performance notebooks needing maximum factory capacity.

Who it suits and who should look elsewhere

The kit suits owners of DDR5-enabled laptops with two free slots who want the highest single-kit capacity currently offered in this form factor. It will not work in DDR4-only notebooks, nor in systems limited to 32 GB total memory or single-slot designs. Buyers needing ECC error correction or registered modules must choose a different product line.

The spec that decides fit

The decisive figure is the DDR5 5600 (PC5 44800) speed combined with the 262-pin SO-DIMM interface; only laptops explicitly validated for DDR5 5600 can install and run this memory at its rated specification.

Questions about this item

Does the DDR5 5600 rating mean the modules run at PC5-44800 bandwidth?

Yes, the kit is rated DDR5 5600 which corresponds to PC5-44800 bandwidth.

Will these 262-pin SO-DIMMs fit a laptop that takes DDR5 memory?

They are 262-pin DDR5 SO-DIMMs, the standard form factor for DDR5 laptop slots.

Do I need to enable anything in BIOS after installing the two 32 GB sticks?

Most laptops detect the 5600 MT/s speed automatically; if the speed shows lower, enable the XMP or equivalent profile in BIOS.
