OWC 4GB DDR3 1066 SODIMM for HP Pavilion dm1

This OWC module is a 4GB DDR3 1066 PC3-8500 CL7 2Rx8 204-pin 1.5V Non-ECC SODIMM built specifically for HP Pavilion dm1 series laptops that use DDR3 memory. It arrives new and is validated to meet the original system specifications.

Who can use this upgrade and who cannot

Owners of an HP Pavilion dm1 needing a single 4GB DDR3 stick will find this a direct fit, while systems that require ECC, registered modules, a different pin count or a voltage other than 1.5V cannot use this part. Buyers whose laptop takes a different DDR generation or a higher-density module should look elsewhere.

The specification that decides compatibility

The module runs at DDR3 1066 (PC3-8500) with CL7 latency at 1.5V in a 204-pin unbuffered SODIMM form factor; matching these exact electrical and physical parameters is what determines whether the upgrade will work.

Highlights

  • 4GB capacity lets you run more apps simultaneously
  • DDR3 1066 speed matches HP Pavilion dm1 requirements
  • CL7 latency improves data access responsiveness
  • 5V operation ensures stable laptop performance
  • 204-pin SODIMM form factor fits dm1 memory slots

Questions about this item

My laptop only has DDR3 slots — will this 204-pin SODIMM fit?

Yes, the module uses the standard 204-pin DDR3 SODIMM form factor that matches the memory slots in the HP Pavilion dm1 series.

I want to keep my existing 2 GB stick and add this 4 GB module — will they run together?

The board will operate both modules at the slower stick's speed and timings, so the 4 GB module will down-clock to match the 2 GB module.

After installing the module, how can I confirm it is running at 1066 MHz CL7?

Open Task Manager's Performance tab or run CPU-Z; the memory section will show 1066 MT/s and CAS latency 7 when the module is detected correctly.
