System-Specific DDR3 SODIMM for Acer Aspire

This 2 GB DDR3 1066 MHz module is built specifically for the Acer Aspire One 5336-2615 notebook series. It uses a 204-pin SO-DIMM form factor and runs at 1.5 V with CL7 timing. The single-rank design ensures straightforward installation in the compatible slot.

Steady Operation at Rated Speed

The module maintains its 1066 MHz data rate under continuous workloads thanks to standard DDR3 signalling and unbuffered architecture. With a fixed CL7 7-7-7 latency cycle and 1.5 V supply, it delivers consistent throughput without throttling during extended sessions. Major-brand chips provide stable signal integrity across the operating temperature range.

Direct Replacement for Factory Memory

This stick matches the original 2 GB DDR3 specification found in the Aspire One 5336-2615 and listed Aspire One 721 variants. It upgrades a single populated socket or fills the empty second slot up to the platform's 4 GB maximum. The jump is worthwhile when the system currently runs on a single module and the user needs additional capacity for multitasking.

Questions about this item

How much heat or power does the 1.5V DDR3 SODIMM add when the notebook runs all day?

The module operates at 1.5 V and uses unbuffered DDR3 chips without a heat spreader, so its thermal contribution is minimal inside the Acer Aspire One chassis.

What must the notebook already have for this 204-pin DDR3 stick to work?

A free DDR3 SO-DIMM slot and a memory controller that supports PC3-8500 1066 MHz CL7 timing — the Acer Aspire One 5336-2615 and listed 721-series models meet this requirement.

Will this 2 GB module run alongside the original 2 GB stick in the 721-3922 that maxes at 4 GB?

Yes — the 721-3922 ships with one 2 GB module in one of two sockets; adding this identical 2 GB DDR3-1066 SODIMM fills the second slot for the supported 4 GB maximum.
