8GB DDR3 SO-DIMM kit for Compaq Presario

This 8GB kit contains two 4GB DDR3 1333MHz SO-DIMM modules built for specific Compaq Presario CQ58 and CQ42 notebooks. It is designed for owners of those models who need to restore or maximise the factory memory limit. Buyers with other laptops or desktop systems should look elsewhere because the pin-out and voltage are specific to this platform.

204-pin DDR3 1333 CL7 unbuffered specification

Each module is a 204-pin PC3-10600 SO-DIMM running at 1.5V with CL7 7-7-7 timings and 2Rx8 organisation. The non-ECC, unbuffered design matches the original equipment requirement for the listed Compaq models. If your system demands ECC, registered modules, a different voltage or a different DDR generation, this kit will not work.

Fits two SO-DIMM slots to reach 8GB maximum

The package provides two sticks to populate both memory sockets in the compatible Compaq Presario CQ58-bf9WM, CQ42-158TX and CQ42-258TU notebooks, reaching the 8GB maximum supported by those chassis. It frees the user from mixing old and new modules. Systems with more than two slots, soldered memory or a lower per-slot limit cannot use this kit as intended.

Questions about this item

What real-world speed will I see from the 1333 MHz rating once these modules are installed in my laptop?

The modules run at DDR3 1333 (PC3 10600) with CL7 timing; actual throughput depends on the memory controller in the specific Compaq Presario model.

What does the PC3 10600 designation mean for the memory interface in practice?

PC3 10600 identifies the DDR3 1333 standard; the 204-pin SO-DIMM slot in the listed Presario systems accepts this exact specification.

Will the 204-pin SO-DIMM sticks fit the two memory sockets in a Compaq Presario Cq42 or Cq58?

Yes, the kit contains two 4 GB 204-pin DDR3 SO-DIMMs, matching the two sockets and 8 GB maximum specified for those models.
