Elpida 2 GB DDR3 laptop kit

This kit supplies two 1 GB unbuffered DDR3 SO-DIMM modules for notebooks that accept 204-pin memory. It is aimed at users upgrading older laptops or replacing failed sticks in systems specified for PC3-10600 speed. Buyers who need a single 2 GB module or a higher-density kit should look elsewhere.

Build quality and daily fit

Each module follows the standard 204-pin SO-DIMM form factor and operates at the JEDEC 1.50 V level for broad compatibility. The CL9 latency rating matches the timing tables used by most mainstream chipsets of the DDR3 era. No heat-spreader or tall components are mentioned, so clearance inside tight chassis should not be an issue.

Deciding specification

The kit runs at DDR3 1333 (PC3-10600) with a CAS latency of 9, which is the single figure that determines whether the memory matches the laptop’s qualified-vendor list. If the service manual calls for a different speed grade or lower latency, this kit will not be the correct part.

Questions about this item

What data rate does the DDR3 1333 (PC3 10600) interface provide for these modules?

The DDR3 1333 (PC3 10600) interface runs at 1333 MHz with a PC3 10600 data rate on each 1 GB module.

What physical slot and notch position do the 204-pin SO-DIMMs require?

Each module uses a 204-pin DDR3 SO-DIMM form factor with the standard DDR3 notch key for laptop memory slots.

How are the two 1 GB sticks installed, and what alignment step is often missed?

Insert each stick at an angle into a 204-pin SO-DIMM slot until the notch aligns, then press down until the side clips click.
