DDR3 SODIMM upgrade kit

This A-Tech kit supplies two 2 GB DDR3 SODIMM modules for a total of 4 GB. The sticks run at 1066 MHz with a CL7 latency and use the standard 204-pin unbuffered, non-ECC layout found in many laptops and all-in-one PCs.

Builders adding memory to DDR3 laptops

The dual-channel kit suits owners of compatible DDR3 notebooks who want a straightforward capacity increase. It will not help users whose machines require a different DDR generation, need ECC or registered modules, or only have a single memory slot available.

1066 MHz CL7 DDR3 speed grade

The decisive specification is the DDR3 1066 MHz (PC3-8500) rating with CL7 timing; the system must accept this exact speed and latency for the modules to operate correctly.

Questions about this item

What pin-count SODIMM slot does this 204-pin DDR3 kit require?

It fits a standard 204-pin DDR3 SO-DIMM socket found in compatible laptops and all-in-one systems.

Which orientation notch on the 204-pin module must align with the slot key during installation?

The single off-centre notch on the gold-edge connector matches the slot key; press both ends until the side clips click.

When should the two 2 GB modules be replaced if the system starts failing memory tests?

Swap them out when diagnostics report persistent errors, as the chips have no moving parts and no scheduled refresh interval.
