Dell Inspiron E1705 upgrade kit

This two-stick kit delivers 2 GB of DDR2 memory for the Dell Inspiron E1705 notebook. Each module is a 1 GB 200-pin SO-DIMM rated at 667 MHz with CL5 timing. The unbuffered non-ECC design matches the original specification. Buyers who need more than 2 GB or a different form factor cannot use this kit.

Two matched modules simplify installation

The package contains two 1 GB sticks that are tested together for dual-channel operation. Using a matched pair avoids the timing mismatches that can occur when mixing individual modules. No extra software or drivers are required. Systems that only have one memory slot cannot take advantage of the pair.

Straightforward notebook installation

The SO-DIMMs insert into the standard 200-pin slots at 1.8 V without tools. The most common issue is seating the module fully until the retention clips click. If the notebook does not recognise the new memory, re-seat both sticks and verify the BIOS is up to date. Damage to the gold contacts during handling can also prevent detection.

Questions about this item

Will the 200-pin DDR2 SO-DIMM modules need any firmware updates or periodic re-seating over time?

No firmware updates are required; the modules are unbuffered non-ECC DDR2 running at 1.8 V, so only occasional dust removal from the slots is needed.

What limit appears first when the kit runs continuously at 667 MHz CL5 in a Dell Inspiron E1705?

The DDR2 5300 bandwidth ceiling is reached before thermal throttling, because the sticks have no heat spreader and operate at standard 1.8 V.

How much noise and heat do the two 1 GB sticks produce during all-day operation?

Silent solid-state operation with no moving parts; heat output stays low at the rated 1.8 V, so the laptop fan profile does not change.
