OWC 4GB DDR3 upgrade for Dell Inspiron

This OWC module adds 4GB of DDR3 memory to Dell Inspiron 620s and 620 desktops. It runs at 1333MHz with PC3-10600 timing and CL9 latency. The 240-pin unbuffered DIMM operates at 1.5V without ECC.

Replaces factory memory or fills an empty slot

Swapping the original sticks for this JEDEC-compliant kit raises total capacity and lets the system keep more programs open. The jump is worth it when the current configuration falls short of 8GB or when multitasking feels sluggish.

Suits owners of compatible Inspiron models

Buyers who need more than a single 4GB module or who run a different motherboard should look elsewhere. Systems that require registered or ECC memory cannot use this unbuffered non-ECC design.

What is the correct way to seat the module, and what step do people often miss?

Align the notch on the module with the slot key, press down firmly until both side clips click into place; the step often missed is checking that both clips have fully locked.
