2GB DDR3 1066 SODIMM for compatible laptops

This 204-pin SODIMM module provides 2GB of DDR3 memory rated at 1066MHz with CL7 latency. It operates at 1.5V and uses an unbuffered, non-ECC design with a single-rank x8 organisation. The module suits laptops or small-form-factor systems that accept DDR3 SODIMMs at this speed and voltage.

DDR3 1066 speed ceiling and voltage match

The DDR3 1066 (PC3 8500) interface caps data-rate at 1066MHz, so any faster modules added to the same system will down-clock to this speed. All installed memory must run at 1.5V; mixing voltages is not supported. Total usable memory also depends on the operating system, with a 64-bit OS required to address more than 4GB.

Upgrade from lower capacity or slower DDR3 SODIMMs

This module replaces a smaller or slower DDR3 SODIMM in systems that support 1066MHz operation. The jump is worthwhile when the current configuration limits multitasking or prevents a 64-bit OS from using its full address space. It does not suit systems requiring ECC, registered DIMMs, or a different DDR generation.

Questions about this item

Should I pick this single 2GB DDR3 1066MHz SODIMM or look for a matched pair kit?

The module is sold as a single 2GB stick; adding a second identical module enables dual-channel operation on platforms that support it.

What does the PC3-8500 1066MHz rating actually deliver in my laptop?

It sets the maximum data rate to 1066 MT/s with CL7 timing; the system will run at the slowest installed module or the CPU memory controller limit.

Does the 204-pin SODIMM interface limit bandwidth compared to a DIMM?

The 204-pin SODIMM form factor carries the same DDR3 1066 signal; bandwidth is capped by the 1066 MT/s speed grade, not the pin count.
