4GB DDR3 SODIMM for Dell XPS Studio 1640

This 4 GB DDR3 SODIMM module is built to upgrade a Dell XPS Studio 1640 laptop. It uses a 204-pin SO-DIMM form factor and runs at 1333 MHz with PC3-10600 bandwidth. The stick operates at 1.5 V with CL7 timing and is unbuffered non-ECC memory. It installs directly into one of the two available memory slots.

Who this suits and who should look elsewhere

This module suits owners of a Dell XPS Studio 1640 who need a single 4 GB upgrade to reach the 8 GB system maximum. It is not for users whose laptops require a different pin count, voltage or DDR generation. Buyers needing more than 4 GB per slot or a dual-rank configuration beyond 2Rx8 should verify their platform requirements first.

The specification that decides fit

The 204-pin DDR3 SO-DIMM interface at 1.5 V determines whether this part fits your laptop. The system must accept PC3-10600 speed and unbuffered non-ECC memory in a 204-pin slot. If your device uses a different pin layout or voltage, this module will not install.

Questions about this item

Will the 204-pin DDR3 SODIMM need any firmware updates or replacement after installation?

The module is a standard 204-pin DDR3 SODIMM with no firmware; it requires no updates and has no user-serviceable parts to replace later.

What limit appears first when running the 1333 MHz CL7 memory continuously in the Dell XPS Studio 1640?

The system maximum of 8 GB across two slots is reached with two 4 GB modules, so capacity is the first hard limit under sustained use.

How much heat and power does the 1.5 V unbuffered stick produce during all-day operation?

At 1.5 V without a heat spreader, the SODIMM draws minimal power and runs cool enough for continuous use in the laptop chassis.
