Capacity and Form Factor

This is a Crucial CT25664BC1067 2 GB DDR3 laptop memory module built to the 204-pin SO-DIMM standard. It runs at 1066 MHz with a CAS latency of CL7 and operates at the standard 1.5 V for unbuffered, non-ECC DDR3. The module is sold in a retail package and is highlighted as Intel compatible.

Suitable Systems and Limitations

This module suits owners of older notebooks or small-form-factor platforms that specifically require DDR3 1066 (PC3-8500) SO-DIMMs. It will not work in systems that only accept DDR3 1333 (PC3-10600) or faster speeds, nor in machines that demand ECC or registered memory. Buyers needing more than 2 GB per slot should look elsewhere.

Deciding Specification

The single specification that decides fitment is the 204-pin DDR3 SO-DIMM interface combined with the 1066 MHz speed rating. A laptop's memory slot must accept this exact form factor and speed grade; any other DDR generation or pin count will physically prevent installation or cause the system to fail POST.

Questions about this item

Will the 204‑pin DDR3 1066 module run at its rated speed in a laptop that currently uses DDR3 1066 memory?

Yes, the module is rated DDR3 1066 (PC3 8500) with CL7 latency and 1.50 V; it will operate at that speed if the laptop also supports DDR3 1066.

How can I confirm the CT25664BC1067 is running at DDR3 1066 after installation?

Check the memory speed in the BIOS or a system-information tool — it should report 1066 MHz (PC3 8500) with CL7 timings at 1.50 V.

What comes in the retail package of the CT25664BC1067 and is anything else required?

The retail box contains the 2 GB 204‑pin DDR3 SO‑DIMM only; no extra cables, adapters or heat spreader are included or required.
