A-Tech 4 GB DDR2 800 MHz SODIMM

This A-Tech module adds four gigabytes of DDR2 memory to compatible laptops, notebooks and all-in-one PCs. It uses the 200-pin SO-DIMM form factor and runs at the standard 1.8 V. The kit targets owners of older systems that still rely on DDR2 technology and need a straightforward capacity increase.

Sustained workload behaviour

The memory operates at 800 MHz with CL6 latency and is unbuffered non-ECC. Under continuous load it maintains its rated speed without throttling because it draws only the standard DDR2 voltage. It is not suited for platforms that require registered or error-correcting modules.

Thermals noise and power

As a passive component the stick produces no audible noise and adds minimal heat inside the chassis. Power draw stays at the nominal 1.8 V level defined by the DDR2 specification. No active cooling or extra airflow is needed for normal operation.

商品問答

How much heat does the 1.80V DDR2 module add when running all day?

It operates at the standard DDR2 voltage of 1.80V, so thermal output matches other PC2-6400 SODIMMs and stays within normal laptop cooling limits.

What must my laptop already have to accept this 200-pin DDR2 stick?

A free 200-pin DDR2 SO-DIMM slot and a memory controller that supports PC2-6400 speed at CL6 latency.

Will this CL6 DDR2 800MHz module slow down if paired with older CL5 DDR2 memory?

The system will run both modules at the slower CL6 timing and 800MHz speed, so the older CL5 stick simply operates at the same relaxed latency.
