Compatible Dell Inspiron 545S Upgrade

This 4GB kit contains two 2GB DDR2 DIMMs built for the Dell Inspiron 545S series. Each stick runs at 667MHz with CL5 timings and 1.8V voltage. The modules are unbuffered, non-ECC and use major-brand chips. They install directly into the desktop's 240-pin slots.

Suits owners of that specific Dell model

Buyers with a different motherboard or a system that requires ECC or registered memory should look elsewhere. The kit is also unsuitable for anyone needing more than 4GB in this package or a different DDR generation.

Speed and latency define the match

The PC2-5300 rating and CL5 timing are the critical figures that decide whether this kit matches the board's memory controller. Verify those numbers against the system manual before ordering.

Questions about this item

Will the 240-pin DDR2 modules need any cleaning or contact maintenance over time?

The gold-edge contacts on these unbuffered DIMMs are designed for long-term seating in the Dell Inspiron 545S slots; no periodic cleaning or re-seating is required under normal indoor use.

What limit appears first when the system runs at the rated 667 MHz speed continuously?

The DDR2 667 specification caps sustained throughput at the PC2-5300 bandwidth level, so memory bandwidth is the first bottleneck before thermal or voltage limits are reached.

How much heat and power do the two 2 GB sticks draw at 1.8 V during all-day operation?

Each module operates at the standard DDR2 1.8 V without a heat spreader, so total power draw and heat output remain low enough for the desktop's stock airflow to handle continuously.
