Purpose-built upgrade

This 8 GB kit (2 × 4 GB) of 204-pin DDR3 SODIMMs is engineered specifically for the Dell XPS Studio 1640 notebook. It runs at 1333 MHz with CL7 timings and 1.5 V unbuffered operation, delivering a straightforward memory refresh for that platform.

Right system, right slots

The kit suits owners of the XPS Studio 1640 who need to populate both of the machine’s two SODIMM slots to reach the 8 GB maximum. It is not for laptops that use a different pin count or voltage, nor for builders working on desktops or other notebook models.

Matching the slot count

The decisive detail is the 204-pin SODIMM form factor paired with the 8 GB total capacity, which exactly matches the XPS Studio 1640’s two-slot limit and 8 GB ceiling. Confirm your system has two free slots before ordering.

Questions about this item

My Dell XPS Studio 1640 has two memory slots — will this 2×4 GB kit fill both of them?

Yes, the laptop provides two SODIMM slots and the kit contains two 4 GB modules, so both slots will be occupied.

Can I keep one existing 4 GB module and add just one stick from this kit?

The kit is sold as a matched pair; using a single stick alongside an older module may work but is not the validated configuration.

After installing both sticks, how can I confirm the system sees the full 8 GB at 1333 MHz?

Open Task Manager or the BIOS memory screen — it should report 8 GB total and a speed of 1333 MHz (PC3-10600).
