Compatible Dell Studio 15 1555 memory kit

This two-module kit delivers 4GB of DDR2 SO-DIMM memory built for the Dell Studio 15 1555 notebook. Each stick is a 2GB, 200-pin unbuffered module running at 800 MHz with CL6 timings. The set is brand new and validated for that specific system.

Not for other DDR generations or pin counts

The modules use DDR2 technology and a 200-pin layout, so they will not work in laptops that require a different memory generation or a different pin configuration. Buyers needing ECC or registered memory should also look elsewhere.

DDR2 800 speed with CL6 latency

The rated speed is PC2 6400 at 800 MHz and the CAS latency is CL6 with 6-6-6 timing. Matching these figures to the notebook’s specification is the single factor that decides whether this kit is the correct upgrade.

Questions about this item

Will these 200-pin DDR2 SO-DIMM sticks fit the two memory slots in a Dell Studio 15 1555?

Yes, the kit is built for that notebook and uses the 200-pin SO-DIMM form factor that matches the system's two slots

What is the correct way to seat each 200-pin module so the clips engage?

Align the notch on the module with the key in the slot, insert at an angle, then press down evenly until both retention clips snap into the notches

When should the 2Rx8 DDR2 800 modules be replaced or checked for errors?

Run a memory diagnostic if the system becomes unstable; the sticks carry a limited lifetime warranty from the manufacturer for defect replacement
