8GB DDR3 1066 SO-DIMM Kit

This 8GB kit contains two 4GB unbuffered SO-DIMM modules built to the DDR3 1066 (PC3 8500) standard. Each stick uses a 204-pin layout, runs at 1.5V with CL7 7-7-7 timings and is configured as 2Rx8 rank. The kit is validated for Acer Aspire 5733Z models 4845, 4469 and 4477.

Owners of listed Acer Aspire 5733Z notebooks

The modules are a direct fit for the three Aspire 5733Z part numbers shown in the compatibility list. Systems that require ECC, registered memory, a different pin count, a higher or lower DDR3 speed grade, or more than two slots will not accept this kit.

Two-slot 8GB maximum capacity

The target notebooks provide exactly two memory slots and support a total of 8GB, so this 2x4GB kit fills the platform to its limit. Buyers whose machines have a different slot count or a higher ceiling need a different capacity configuration.

Domande su questo articolo

How do I install the 204-pin DDR3 SO-DIMM modules in my Acer Aspire 5733, and what step often causes a failed boot?

Power off the laptop, unplug the adapter and remove the battery if accessible, open the memory door, align the notch on each module with the slot key, insert firmly until the gold contacts disappear, then press down until both side clips click — the step most often missed is not seating the module fully before locking the clips.

Will the two 4GB sticks need any maintenance or replacement during the laptop's life?

No routine maintenance is required; the modules are solid-state with no moving parts, but if a stick ever fails the limited lifetime warranty from Computer Memory Solutions covers exchange or repair against manufacturing defects.

What is the first limit reached when the memory runs at 1066 MHz continuously under heavy load?

The 1.5V operating voltage and CL7 7-7-7 timing are fixed by the JEDEC DDR3-1066 standard, so sustained throughput is capped at the PC3-8500 bandwidth ceiling rather than by thermal throttling, as there is no heat spreader.
