4GB DDR3 1066MHz SODIMM

This A-Tech module adds 4GB of DDR3 memory at 1066MHz (PC3-8500) to a laptop or all-in-one system. It uses the standard 204-pin SO-DIMM form factor and runs at 1.50V with CL7 latency. The stick is unbuffered, non-ECC and built with major-brand chips for broad AMD and Intel platform compatibility.

Suits owners of compatible IBM-Lenovo models

The module directly replaces Lenovo part numbers 41R0636, 51J0493, 51J0494, 55Y3708 and 55Y3714. Buyers needing more than 4GB of total memory or requiring ECC or registered DIMMs should look at other parts. Systems that do not accept 204-pin DDR3 SO-DIMMs cannot use this upgrade.

204-pin DDR3 SO-DIMM interface

The single specification that decides fitment is the 204-pin DDR3 SO-DIMM interface running at 1066MHz. If the laptop manual lists this exact form factor and speed, the module will install and operate at its rated CL7 timing.

Domande su questo articolo

Should I pick the 4 GB module or look for a different capacity?

This listing is a single 4 GB DDR3 SODIMM; choose it if your laptop has a free 204-pin slot and the manufacturer qualifies 4 GB modules at 1066 MHz.

What does the 1066 MHz rating deliver in my laptop?

The module runs at 1066 MHz with CL7 latency at 1.5 V, giving the standard DDR3 1066 data rate your memory controller expects.

Is the PC3-8500 label tied to a specific interface or voltage limit?

PC3-8500 identifies DDR3 1066 on the 204-pin SO-DIMM interface at the standard 1.5 V unbuffered specification.
