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.

Küsimused selle toote kohta
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.
