Everyday DDR3 laptop upgrade

This 2GB DDR3 SO-DIMM runs at 1333MHz with CL9 timing and 1.50V operation. The unbuffered, non-ECC module uses a 204-pin layout and carries model number 991646. It targets notebooks that need a simple capacity boost for smoother multitasking.

Replaces slower or smaller DDR3 sticks

Swapping a 1GB module or a lower-speed DDR3 part for this 2GB CL9 unit raises usable bandwidth toward 10.6GB per channel. The jump is worth it when the laptop has a free slot or when all slots hold slower memory. Builders who need more than 2GB per module or who require ECC support must look elsewhere.

Check slot count and maximum module size

Verify the notebook accepts 204-pin DDR3 SO-DIMMs and note the vendor's per-slot capacity limit. Confirm the system runs memory at 1.50V rather than a lower-voltage standard. No heat spreader is fitted, so ensure the chassis provides adequate airflow around the memory bay.

Questions about this item

Will this 204-pin SO-DIMM fit my laptop's memory slot?

The module uses the standard 204-pin DDR3 SO-DIMM form factor used by most DDR3-era laptops.

How do I install the module correctly?

Align the notch on the gold edge connector with the key in the slot, insert at an angle, then press down until the side clips lock.

Does this 1.50V DDR3 module need a heatsink or replacement over time?

It has no heat spreader and runs at standard 1.50V; no active cooling or scheduled replacement is required.
