16 GB DDR4 SO-DIMM for Acer Aspire 5

This 16 GB DDR4 2400 CL17 module is built for the Acer Aspire 5 A515-51 series, including the 596K, 59VV, 75UY and 84PS models. It uses a 260-pin SO-DIMM form factor and runs at 1.2 V without ECC or buffering. The single-stick kit suits owners who want to reach the platform ceiling in one step.

DDR4 2400 speed ceiling and single-slot limit

The notebook platform tops out at 20 GB total capacity across one socket, so this 16 GB stick leaves only 4 GB of headroom if the original 4 GB module remains. All installed memory will operate at the slowest module speed or the processor’s maximum supported rate. A 64-bit operating system is required to address more than 4 GB.

Unbuffered design with major-brand chips

The module uses major-brand chipset components in a 2Rx8 configuration without a heat spreader, keeping the profile low for tight laptop chassis. Computer Memory Solutions manufactures the stick directly rather than rebranding generic modules, and backs it with a limited lifetime warranty against manufacturing defects when purchased from them.

Questions about this item

Should I choose the 16GB single stick or add a second module to reach the 20GB maximum?

The laptop has one memory socket and supports up to 20GB total, so this 16GB stick fills the only slot and leaves 4GB of the limit unused.

Will the 2400MHz CL17 rating run at that speed in my Acer Aspire 5 A515-51?

The module is rated DDR4 2400 CL17, but the system will operate at the slowest speed among the CPU, any existing memory and this stick.

Does the 260-pin DDR4 SO-DIMM interface limit bandwidth compared to desktop DIMMs?

The 260-pin SO-DIMM form factor carries the same DDR4 2400 signal; the pin count only reflects the smaller notebook outline, not a lower data rate.
