Targeted upgrade for Dell Inspiron 9400

This 4 GB kit contains two 2 GB DDR2 SO-DIMM modules built to PC2-5300 speed. It is made for owners of the Dell Inspiron 9400 notebook who need to reach the 4 GB maximum supported by that platform.

Fits the two factory slots directly

The 200-pin unbuffered modules install without tools into the two SODIMM sockets inside the Inspiron 9400. Using both sticks fills the available slots and frees no further expansion room for additional memory.

Low-voltage DDR2 runs cool and quiet

Operating at 1.8 V with CL5 5-5-5 timing, the sticks produce minimal heat and have no moving parts. Power draw stays modest during typical office workloads and web browsing.

Questions about this item

Will the CL5 latency and 1.8 V voltage limit how long this DDR2 kit can run at 667 MHz under heavy load?

The modules are rated CL5 at 1.8 V, the standard timing and voltage for DDR2-667, so they sustain that speed without exceeding spec.

How much heat or fan noise should I expect from these unbuffered SODIMMs during all-day use in a Dell Inspiron 9400?

No heat spreader is fitted, but DDR2 SODIMMs at 1.8 V run cool; the laptop’s existing cooling handles the small thermal load silently.

My Inspiron 9400 has two 200-pin slots — does this 2 x 2 GB kit fill them both?

Yes, the kit provides two 200-pin DDR2 SODIMMs for a total of 4 GB, matching the two-slot layout of the Inspiron 9400.
