2GB DDR2 SO-DIMM for older laptops

This 200-pin Mushkin Enhanced Essentials module adds 2GB of DDR2 667 memory to compatible notebooks. It runs at 1.80V with CL5 5-5-5-15 timings and is unbuffered non-ECC. The 991559 is a straightforward capacity upgrade for systems limited to DDR2 technology.

Suits DDR2 667 notebooks only

Owners of laptops that accept PC2 5300 SO-DIMMs can use this stick to improve multitasking responsiveness. Buyers whose machines require a different pin count, voltage or memory generation cannot install this module. Systems already at their maximum supported capacity will not benefit.

667MHz DDR2 speed rating

The module operates at 667MHz delivering up to 5.3GB per channel bandwidth. This single speed figure determines whether the part matches the laptop's memory controller. Verify the existing RAM runs at PC2 5300 before purchase.

Preguntas sobre este artículo

Does the 200-pin DDR2 SO-DIMM need any periodic cleaning or part replacement?

No maintenance is required; the module has no moving parts, no heat spreader, and no user-serviceable components.

What limit appears first when the CL5 5-5-5-15 module runs at full 667 MHz load for hours?

The memory controller’s 5.3 GB/s bandwidth ceiling is reached before any thermal or timing bottleneck on this unbuffered stick.

How much heat and power does the 1.80 V stick produce during all-day operation?

It draws 1.80 V with no heat spreader, so warmth stays low and fan noise is unaffected in a typical laptop chassis.
