Targeted DDR3 SODIMM Upgrade
This 4 GB DDR3-1066 module is built for the HP Compaq Presario CQ57-214NR and CQ57-487SA notebooks. It arrives as a single 204-pin SO-DIMM rated at PC3-8500 with CL7 timings and 1.5 V operation. The unbuffered, non-ECC design matches the factory specification for these systems.
Replaces Slower or Smaller Factory Modules
The kit upgrades the original memory when the laptop shipped with 2 GB or a lower-speed DDR3 stick. Adding this 4 GB rank 2Rx8 module fills one of the two available sockets and raises the total toward the 8 GB platform maximum. The jump is worthwhile when the system currently swaps to disk during everyday multitasking.
Limited by DDR3-1066 Bus and Two-Socket Design
The memory controller in these notebooks caps transfer rate at 1066 MHz, so faster DDR3 modules will downclock to this speed. Only two SO-DIMM slots exist, setting a hard ceiling of 8 GB total capacity. Buyers who need more than 8 GB or a higher memory bandwidth must choose a different platform.

Questions about this item
Does the 204-pin DDR3 SODIMM fit the HP Compaq Presario CQ57-214NR laptop?
Yes, the module is built to the 204-pin DDR3 SODIMM form factor that the CQ57-214NR and CQ57-487SA require.
What is the correct slot orientation when installing the CM512648500SODRH stick?
Align the notch on the gold edge with the key in the socket, press firmly until both side clips click, then verify the stick sits flat.
Will the CL7 1.5 V module need a voltage adjustment or firmware update later?
No, it runs at the standard 1.5 V DDR3 voltage with CL7 timing, so no BIOS voltage change or firmware update is required.
