16 GB DDR4 SO-DIMM for Acer Aspire 5

This 16 GB DDR4 2400 SO-DIMM module is built for Acer Aspire 5 models A515-43G, A515-43-R19L, A515-43-R4Z2 and A515-43-R5RE. It uses a 260-pin unbuffered non-ECC design with CL17 timing at 1.2 V. The single stick upgrades one of two available slots up to a 32 GB system maximum.

Sustained load behaviour with CL17 timing

Under continuous workloads the module runs at its rated 2400 MHz with 17-17-17 latencies and 1.2 V. All installed memory operates at the speed of the slowest module or the processor limit. Matched-pair installation enables dual-channel throughput for steadier bandwidth during long sessions.

Upgrade path from smaller single modules

Replacing a lower-capacity stick with this 16 GB unit raises the ceiling toward the 32 GB dual-channel maximum. The jump is worthwhile when the current configuration leaves headroom unused and the processor can address 64-bit memory space. Buyers needing more than 32 GB total or a second matched stick for full dual-channel bandwidth should look elsewhere.

Questions about this item

Does the 1.2V DDR4 SO-DIMM run cooler than higher-voltage modules during all-day use?

DDR4 at 1.2V is the standard low-voltage design, so heat output stays modest even under continuous load.

Will my Acer Aspire 5 need a 64-bit OS to use this 16GB stick?

Yes, a 64-bit operating system is required to address more than 4GB of memory.

If I keep the original module in the second socket, will both sticks run at the slower module's speed?

All installed memory runs at the slowest module's performance, so mixing speeds drops the faster stick to match.
