Dell Inspiron 17 (1721) Memory Upgrade

This 4 GB kit uses two 2 GB DDR2 SODIMM modules built for the Dell Inspiron 17 (1721) notebook. It targets owners of that specific model who need to restore or expand system memory. The modules are unbuffered, non-ECC and run at 1.8 V.

200-Pin DDR2 SO-DIMM Installation

Each stick fits a standard 200-pin DDR2 SO-DIMM slot inside the notebook. The kit occupies both available sockets, so no spare slot remains for further expansion. Installation requires no additional cables, adapters or configuration changes beyond seating the modules.

4 GB Total Capacity at DDR2 800

The pair delivers 4 GB of memory at PC2-6400 speed with CL6 timing, suitable for everyday applications and light multitasking on the supported platform. Systems limited to 4 GB maximum will reach their ceiling with this kit, while boards that accept more will still have headroom for larger modules.

商品問答

Will the CL6 latency at 800 MHz become the bottleneck during long rendering sessions?

The modules run at CL6 6-6-6 timing, so latency is fixed at that level for sustained workloads.

How much heat do these 1.8 V sticks produce when the laptop runs all day?

They operate at 1.8 V with no heat spreader, so thermal output stays low inside the chassis.

Does my Inspiron 17 1721 need a specific BIOS version before I install this 2x2 GB kit?

The kit is validated for the Dell Inspiron 17 1721 notebook; no extra hardware is required.
