Capacity and purpose

This 512MB DDR2 533 module adds a single stick of PC2 4200 memory to a desktop that uses unbuffered DIMM slots. It suits owners of older systems who need a modest capacity boost for basic office or legacy software tasks.

Build fit

The stick runs at 1.80V and carries a CL4 latency rating, so it slots straight into any board that accepts unbuffered DDR2 at this speed without extra configuration. It frees a second slot for another identical module if the platform supports dual-channel operation.

Thermals noise power

With no heat-spreader or active cooling the module relies on case airflow and draws only the standard 1.80V supply current. It adds no audible noise and its thermal contribution is negligible inside a normally ventilated chassis.

Questions about this item

What limits performance when this 512MB DDR2 533 module runs under sustained load?

The single 512MB capacity and DDR2 533 speed ceiling restrict throughput during extended heavy workloads.

How much heat and power does this 1.80V DDR2 stick produce when running all day?

Operating at 1.80V, the unbuffered DDR2 module draws modest power and generates low heat typical for this density.

Which motherboard slot must I already have to install this AA533D2N4/512 desktop memory?

A desktop DDR2 DIMM slot keyed for PC2 4200 modules is required for this 512MB stick to fit and function.
