64 GB DDR4 SODIMM kit

This 4 × 16 GB kit delivers 64 GB of DDR4 memory in 260-pin SODIMM form factor. It runs at 2400 MHz with CAS latency 17 and 1.2 V unbuffered operation. The modules are non-ECC and use 2Rx8 organisation for broad laptop and small-form-factor desktop compatibility.

Limited by DDR4-2400 bus speed

The DDR4-2400 interface caps peak bandwidth at PC4-19200, so throughput cannot exceed that ceiling regardless of CPU capability. All installed modules will clock down to the slowest module or the processor’s memory controller limit. A 64-bit operating system is required to address the full capacity.

Replaces mismatched or lower-capacity SODIMMs

Swapping a mixed set for this matched quad-kit removes speed mismatches and enables dual-channel operation across all slots. The upgrade is worthwhile when the platform supports 64 GB and the workload benefits from consistent 2400 MHz timing rather than falling back to a slower common denominator.

Questions about this item

Should I buy the 4-piece kit or look for a different capacity?

The kit contains four 16GB modules for a total of 64GB; choose it when your laptop has four SODIMM slots and you want the maximum supported capacity in matched pairs.

What does the 2400 MHz rating deliver in daily use?

Rated at 2400 MHz with CL17 timing and 1.2V, the modules run at the standard DDR4-19200 data rate, so bandwidth scales with the CPU memory controller rather than exceeding it.

Will the 260-pin DDR4 SODIMM fit my laptop's memory slot?

Yes — the 260-pin DDR4 SODIMM form factor matches the physical and electrical interface used by laptops that accept DDR4 SO-DIMM memory.
