System-specific DDR4 SO-DIMM

This 8 GB DDR4 2133 MHz module is built for Acer Aspire R5-571TG-78G6, R5-571T-59DC and R5-571T-57Z notebooks. It arrives as a single 260-pin SO-DIMM stick using major-brand DRAM chips. The unbuffered, non-ECC design matches the original memory specification for these systems.

Maximum capacity per slot is 12 GB

The compatible Acer models accept up to 12 GB in their single memory socket. This 8 GB stick leaves headroom below that ceiling while doubling the typical 4 GB factory configuration. Buyers who need the full 12 GB limit should verify whether a 12 GB module exists for this platform.

Low-voltage DDR4 runs at 1.2 V

Standard DDR4 voltage keeps power draw and heat output modest inside the slim Aspire chassis. CL15 timings at 2133 MHz deliver responsive everyday performance without requiring active cooling on the module. The stick has no heat spreader, relying on the notebook's internal airflow.

Questions about this item

Will the 2133 MHz speed run at that rate in my Acer Aspire R5-571TG-78G6?

The module is rated at 2133 MHz (PC4-17000). The notebook's memory controller will set the final speed, so it will operate at up to 2133 MHz if the system supports it.

Does the 260-pin SO-DIMM interface limit the maximum capacity I can install?

The laptop has one 260-pin DDR4 SO-DIMM socket and a maximum supported memory of 12 GB, so this 8 GB stick fits within that limit.

Will the 260-pin SO-DIMM fit the single memory slot in the R5-571T-59DC?

Yes. The module is a 260-pin DDR4 SO-DIMM and the compatible models listed each have one SO-DIMM slot, so it installs directly.
