Dual-channel 16 GB DDR4 SO-DIMM kit

This 260-pin kit delivers 16 GB of DDR4 memory as two matched 8 GB modules. It is built for notebooks and small-form-factor systems that accept SO-DIMM slots and run at 1.20 V. The CL17 latency and 2400 MHz rating suit everyday productivity and multitasking workloads. Buyers needing ECC protection or registered modules should look elsewhere.

Matched pair enables dual-channel bandwidth

The two identical modules let the memory controller run in dual-channel mode, raising practical bandwidth by up to 30 % over a single stick. Lower 1.20 V operation cuts memory power draw by up to 40 %, which helps extend battery life on mobile platforms. No heat spreader is included, so the modules fit tight chassis clearances without added height.

DDR4 2400 sets the speed ceiling

The JEDEC DDR4-2400 standard caps the maximum data rate at 2400 MT/s, so the kit cannot run faster without overclocking support that most laptops lack. CL17 timing is fixed at this speed tier; tighter latencies are not guaranteed. Systems limited to DDR4-2133 will downclock the modules automatically.

Perguntas sobre este artigo

Will the CL17 latency modules need replacing if I move to a platform that requires lower CAS timing?

The kit runs at CL17; a newer platform may benefit from tighter timings, so you would replace them only if the new system demands lower latency.

What limit appears first when the 2400 MT/s SO-DIMMs run continuously at full load?

Sustained throughput is capped by the 2400 MT/s data rate and CL17 latency, which set the maximum bandwidth ceiling before any thermal throttle.

How much heat and power do the 1.20 V unbuffered modules produce during all-day operation?

Rated at 1.20 V without a heat spreader, the modules draw minimal power and generate low heat, helping battery life in typical laptop workloads.
