Compatible DDR3 upgrade for Compaq Presario

This 4 GB kit contains two 2 GB DDR3 SO-DIMM modules rated at 1066 MHz with CL7 timings. It is built for the Compaq Presario Notebook CQ57-210US and CQ57-212NR, which have two memory sockets and a maximum capacity of 8 GB.

Owners of the listed CQ57 models

The kit matches the voltage, pin count and timing those notebooks expect, so installation is straightforward. Users needing more than 8 GB total, ECC protection, registered modules or a different form factor will not be served by this product.

Two-socket limit and 8 GB ceiling

Each notebook accepts only two SO-DIMMs, so this pair fills every slot and reaches half the platform maximum. Buyers planning to exceed 8 GB must choose a different system.

Domande su questo articolo

Should I buy the 2×2 GB kit or look for a single 4 GB stick for my Presario CQ57?

The kit supplies two 2 GB modules that fill both slots on the CQ57-210US and CQ57-212NR, giving the full 4 GB capacity the notebook supports.

What does the 1066 MHz rating deliver once the modules are installed?

The memory runs at 1066 MHz with CL7 timing, matching the DDR3-8500 specification the Presario chipset expects.

Will the 204-pin DDR3 SO-DIMM interface limit bandwidth on this notebook?

The 204-pin DDR3 SO-DIMM connection is the native interface for the CQ57 series, so the 1066 MHz speed is not capped by the slot.
