Dell Studio & XPS DDR3 upgrade

This OWC SODIMM delivers 2GB of DDR3 1066 memory built to JEDEC and RoHS standards. It is tested for compatibility with Dell Studio 1450, 1458, 1745, 1749 and XPS 1647 laptops. The module runs at 1.5V with CL7 latency and uses a 1Rx8 unbuffered design.

Suits owners restoring listed Dell models

The part fits the exact Dell Studio and XPS models named in the specifications. It will not work in systems that require a different voltage, pin count or memory generation. Buyers needing more than 2GB per slot or a different form factor should look elsewhere.

204-pin DDR3 SODIMM form factor

The module uses the 204-pin DDR3 SODIMM interface required by the compatible Dell laptops. This single specification determines whether the upgrade will install and function in the target machine.

Questions about this item

How do I install the 204-pin SODIMM in my Dell Studio 1450, and what step do people often miss?

Power off the laptop, remove the battery, open the memory door, align the notch on the module with the slot key, press firmly until the side clips click, then reassemble — the step many skip is verifying both clips lock audibly.

Will the 1.5V DDR3 module need any maintenance or replacement during the laptop's life?

No routine maintenance is required; the non-ECC unbuffered SODIMM has no moving parts or heat spreader, so it runs until a rare cell failure, at which point you simply swap in another compatible 2GB PC3-8500 stick.

What limit appears first when the 1066MHz CL7 memory runs under sustained heavy load?

The JEDEC-standard 1.5V voltage ceiling is reached before thermal throttling, capping sustained throughput at the rated PC3-8500 bandwidth because the module lacks a heat spreader for extra cooling headroom.
