Single 4GB DDR3 SODIMM

This OWC module delivers 4GB of DDR3 1066 memory in a 204-pin SODIMM form factor. It is built for HP Pavilion dv4 series notebooks that use DDR3 memory. The CL7 latency and 1.5V operation match the original system specifications. Installation is a straightforward DIY upgrade for compatible laptops.

Steady CL7 latency at 1066 MT/s

The module maintains its rated CL7 timings during continuous workloads rather than only in short bursts. JEDEC-standard DDR3 1066 signalling ensures stable data rates across extended sessions. Unbuffered, non-ECC organisation keeps the signal path direct for consistent throughput. Thermal characteristics follow the standard SODIMM envelope without a heat spreader.

DDR3 1066 ceiling for this platform

The HP Pavilion dv4 chipset caps memory speed at DDR3 1066, so faster modules will downclock to this rate. Maximum capacity per slot is defined by the system board, not by this module alone. Builders needing more than 4GB per slot or dual-channel pairs must verify the laptop's total supported memory. This part addresses a single-slot upgrade only.

Questions sur cet article

How much power does the 1.5V DDR3 1066 module draw when the laptop runs all day?

The module operates at the standard 1.5V JEDEC voltage for DDR3 1066, so power draw stays within the laptop's original thermal envelope during continuous use.

What must the HP Pavilion dv4 already have for this 204-pin SODIMM to work?

The dv4 needs a free DDR3 SO-DIMM slot and a BIOS that supports PC3-8500 CL7 memory; the module is unbuffered, non-ECC, and keyed for 204-pin sockets.

Will this 4GB 2Rx8 stick run alongside the original 2GB modules in my dv4?

Yes — it is tested to meet HP OEM specs for the dv4 series, so mixing ranks and capacities works as long as the board accepts 4GB per slot.
