4GB DDR3 1066MHz SODIMM Module

This 4GB DDR3 SODIMM runs at 1066MHz with CL7 timing and 1.5V voltage. The 204-pin unbuffered module uses a 2Rx8 configuration and major brand chipset. It is designed as system specific memory for compatible laptops or small form factor PCs.

Suits repairs needing a single 4GB DDR3 stick

Buyers who want more storage or faster speeds should look at something else. Systems requiring ECC or registered memory cannot use this module. A 64-bit OS is needed to address more than 4GB total system memory.

DDR3 1066MHz speed rating

The PC3 8500 speed rating determines whether this module matches your system requirements. All installed memory will run at the slowest module speed present. Verify your platform supports DDR3 1066MHz before purchase.

Questions about this item

Does the 204-pin SODIMM fit my laptop's DDR3 memory slot?

Yes, the module is a 204-pin SODIMM built for DDR3 1066 MHz (PC3 8500) slots.

How do I install this CM512648500SODRH module correctly?

Insert the module at the slot's required angle, press evenly until the gold contacts are fully seated, then lower it until the side clips click into the notches.

Will this 4 GB 2Rx8 stick need replacement for a 64-bit OS upgrade?

A 64-bit operating system is required to address more than 4 GB, so adding a second matched module is the typical upgrade path.
