Matched Memory for Compaq Presario Cq57-339Wm

This 8GB kit contains two 4GB DDR3 1333MHz SODIMM modules built to the exact specifications of the Compaq Presario Cq57-339Wm laptop. Computer Memory Solutions validates compatibility for this specific model so the memory installs and runs without configuration changes. The CL7 latency and 1.5V operation match the original equipment requirements for stable everyday use.

Ideal for Restoring Factory Capacity.

Owners of the named Presario who need to replace failed modules or fill both slots to the supported 8GB total will find this kit a direct fit. Builders working on any other laptop, desktop or server should look elsewhere because the 204-pin DDR3 form factor and the validated model list are specific to this Compaq system. Systems that require ECC or registered memory cannot use these unbuffered sticks.

1333MHz CL7 Speed Grade Decides Fit

The modules run at PC3-10600 with 7-7-7 timings at 1.5V, so the laptop must support DDR3 1333 at that latency and voltage. If the platform only accepts slower DDR3 grades, higher CAS latency or a different voltage, the memory will not operate correctly. Verify the service manual specifies PC3-10600 CL7 before purchase.

Questions about this item

Will the two 4 GB modules need replacement if I later want more than 8 GB?

Yes, the kit provides 8 GB across two slots, so any capacity increase means removing one or both sticks.

Does the CL7 1333 MHz rating limit bandwidth during long rendering sessions?

The modules run at DDR3 1333 with 7-7-7 timings, so sustained throughput is capped at that speed.

How much heat do the 1.5 V unbuffered sticks produce when the laptop runs all day?

They operate at 1.5 V without heat spreaders, so thermal output stays low under continuous load.
