1GB DDR2 SO-DIMM for older laptops

This 1GB Crucial module uses the 200-pin DDR2 SO-DIMM form factor and runs at 667 MT/s (PC2-5300). It operates at 1.80V with CL5 5-5-5-12 timings and is unbuffered non-ECC. The part is new and suited to notebooks that accept DDR2 memory.

Suits machines with a DDR2 200-pin slot

The module fits laptops designed for DDR2 SO-DIMMs running at 667 MT/s. It will not work in systems that require a different pin layout, a different voltage, or a later memory generation. Buyers whose laptop needs a higher capacity per slot or a faster DDR2 speed grade should look at something else.

200-pin DDR2 SO-DIMM interface decides fit

The only specification that determines compatibility is the 200-pin DDR2 SO-DIMM interface combined with the 667 MT/s speed rating. If the service manual lists PC2-5300 200-pin DDR2, this module matches; otherwise it cannot be installed.

商品問答

Does this 200-pin DDR2 SO-DIMM fit my laptop's memory slot?

This module uses the standard 200-pin DDR2 SO-DIMM form factor. It fits any laptop slot designed for DDR2 667 (PC2 5300) memory. Check your manual to confirm the slot type.

What is the correct way to seat the module so the 200 pins make full contact?

Align the notch on the module with the key in the slot, insert at a 30-degree angle, then press down firmly until the side clips click. The notch position is specific to DDR2.

Will this 1.80V DDR2 module need any firmware updates or battery replacement over time?

No firmware or battery is involved. The module is a passive DRAM component. If a memory error appears later, run a diagnostic tool; a faulty stick is simply replaced.
