Essentials 4GB DDR3 1066 SO-DIMM kit

The Mushkin Enhanced Essentials kit provides 4GB of DDR3 laptop memory in a matched pair of 2GB modules. Model 996643 uses 204-pin SO-DIMM form factor and runs at 1066 MT/s with CL7 timings at 1.50V. The dual-channel configuration is programmed for broad compatibility with existing memory.

For older DDR3 laptops needing a matched pair

This kit suits owners of DDR3 notebooks that accept 204-pin SO-DIMMs and benefit from dual-channel bandwidth of 8.5GB/s. Buyers whose systems require a different DDR generation, ECC functionality, registered modules, or heat spreaders should look elsewhere.

204-pin DDR3 SO-DIMM interface decides fit

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

Questions about this item

What must my laptop already support to use this 204-pin DDR3 SO-DIMM kit?

Your laptop needs DDR3 SO-DIMM slots that accept 204-pin modules and run at 1.50V. The kit is a dual-channel pair of 2 GB sticks rated for DDR3 1066 (PC3 8500) with CL7 7-7-7-20 timings.

How will these CL7 1066 MHz modules behave if my system runs memory at a lower DDR3 speed?

The modules are programmed for maximum compatibility and will run at the highest common speed your platform and any existing memory allow, using the 7-7-7-20 timings at 1.50V.

How can I verify the kit is running in dual-channel mode after installation?

Check your BIOS or a system information tool: it should show 4 GB total across two channels at DDR3 1066 (PC3 8500) with CL7 timings.
