Single 4GB DDR3 1066MHz SODIMM

This A-Tech module provides 4GB of DDR3 memory at 1066MHz (PC3-8500) in a 204-pin SODIMM form factor. It operates at the standard 1.5V with CL7 latency and uses unbuffered, non-ECC chips. The stick is designed as a direct replacement for specific Kingston part numbers in laptop, notebook, and all-in-one systems.

Fits non-ECC DDR3 laptops accepting 1.5V modules

Systems that require ECC, registered memory, a different voltage, or a different pin configuration cannot use this module. Buyers needing more than 4GB per slot or a faster DDR3 speed grade should verify their platform requirements before ordering. The part is validated for AMD and Intel platforms that support this specification.

1066MHz DDR3 speed rating (PC3-8500)

This single specification determines whether the module matches the memory controller in the target machine. If the system requires a different DDR3 frequency, the upgrade will not function correctly. Always confirm the supported speed against the laptop's documentation prior to purchase.

Questions about this item

Does my laptop need a free 204-pin DDR3 SODIMM slot to install this 4GB module?

Yes, it requires one vacant 204-pin DDR3 SO-DIMM socket running at 1.5 V.

If I keep an existing DDR3 stick, will this module run at the same 1066 MHz speed?

The system will operate both modules at the lowest common speed; this stick is rated for 1066 MHz.

How can I confirm the new RAM is detected at 1066 MHz with CL7 timing?

Check the memory tab in CPU-Z or your BIOS — it should show 1066 MHz, PC3-8500 and CL7 latency.
