Targeted DDR4 Upgrade for Select Acer Laptops

This 4GB SODIMM module is built for Acer Aspire E5-575-33BM, E5-774G-52W1 and E5-575G-57D4 notebooks. It adds memory capacity to systems that currently limit multitasking performance. Buyers needing higher total capacity or faster speeds should look elsewhere.

Standard SODIMM Build With Direct Compatibility

The 260-pin unbuffered stick fits the laptop slots without adapters or modifications. Operation at 1.2V matches the platform voltage requirement. No heat spreader is included, keeping the profile low for tight chassis clearance.

2133MHz CL15 Speed Rating Decides Fit

The module runs at DDR4 2133 (PC4 17000) with 15-15-15 timings. Systems requiring a different frequency or latency will not run this memory at its rated specification. Maximum supported capacity per the platform is 32GB across two sockets.

Questions about this item

What DDR4 speed does this module run at and what bandwidth does PC4 17000 provide?

This module runs at DDR4 2133 MHz, labelled PC4 17000, which delivers up to 17 000 MB/s of theoretical bandwidth in a 260-pin SODIMM form factor.

Will the 260-pin SODIMM fit the two memory slots in my Acer Aspire E5-575 or E5-774?

Yes, the 260-pin DDR4 SODIMM matches the two SO-DIMM sockets in the listed Acer Aspire models, which support up to 32 GB total.

How do I install the stick and which orientation mistake should I avoid?

Power off the laptop, open the memory cover, align the notch on the module with the key in the slot, press firmly until the side clips click, then replace the cover; the common error is inserting the stick backwards so the notch misses the key.
