Targeted upgrade for Acer Aspire One 722

This 4 GB DDR3 SO-DIMM is built specifically for the Acer Aspire One AO722-BZ197, AO722-BZ454 and AO722-BZ480 models. It installs directly into the single expansion socket to raise usable memory above the factory limit. Buyers needing more than 4 GB or a second module cannot use this kit.

Low-voltage DDR3 runs cool and silent

The module operates at 1.5 V with CL7 7-7-7 timings at 1066 MHz, drawing minimal power and producing no audible noise. Passive components mean there is no fan to fail or dust to trap. Systems constrained to the original cooling solution see no extra thermal load.

Standard 204-pin form factor fits the sole slot

Unbuffered 1Rx8 construction with major-brand chips ensures reliable seating in the laptop's only memory socket. No heat spreader keeps the profile thin for tight chassis clearance. The single-stick package leaves no orphan module when the upgrade is complete.

Questions about this item

How do I install this 204-pin DDR3 SODIMM in my Acer Aspire One 722 and which step is often missed?

Power off the laptop, remove the battery, open the single memory door, insert the module at an angle until the gold contacts disappear, then press down until both side clips click — the step most people miss is fully seating it before the clips engage.

What maintenance or replacement will this 4 GB 1Rx8 CL7 module need later?

No routine maintenance is required; the unbuffered DDR3 stick has no heat spreader and no moving parts, so it only needs replacement if a memory test reports errors or you upgrade to a higher-capacity kit.

What limit appears first when this 1066 MHz PC3-8500 SODIMM runs sustained workloads?

The single SO-DIMM slot caps total memory at 4 GB, so capacity is the first constraint — bandwidth and latency remain fixed at DDR3-1066 CL7 regardless of load duration.
