Capacity and Form Factor

The Mushkin Enhanced 991647 is a 4 GB 204-pin DDR3 SO-DIMM designed for laptop memory upgrades. It operates at 1333 MHz with a CAS latency of CL9 and a voltage of 1.50 V. This unbuffered, non-ECC module delivers up to 10.6 GB/s bandwidth per channel for everyday computing tasks.

System Fit and Limitations

This module suits owners of DDR3-based laptops that accept 204-pin SO-DIMMs running at 1.50 V. Buyers whose systems require a different memory generation, a different pin count, low-voltage 1.35 V operation, ECC functionality or registered buffering should look at other options.

Deciding Specification

The 204-pin DDR3 SO-DIMM interface is the single specification that determines whether this module will physically install and function in a given laptop. Verify the slot type and voltage requirement before purchase.

Questions about this item

How does the 1333 MHz speed translate to real-world bandwidth in my laptop?

The module is rated at PC3 10666, delivering up to 10.6 GB/s per channel for responsive multitasking and faster program switching.

What does the 204-pin SO-DIMM interface mean for compatibility?

It uses the standard DDR3 SO-DIMM form factor with 204 pins, keyed for laptop memory slots that accept DDR3 modules.

Will the CL9 9-9-9-24 timings require any voltage adjustment to run stable?

It operates at the standard 1.50 V for DDR3, so the JEDEC timings run without manual voltage changes in the BIOS.
