HP Pavilion dm4 DDR3 Upgrade

This OWC module is a 4 GB DDR3 SODIMM built for HP Pavilion dm4 laptops that use DDR3 memory. It runs at 1066 MHz with a PC3-8500 rating, CL7 latency and 1.5 V operation. The stick is a single-rank 2Rx8 design on a 204-pin unbuffered PCB without a heat spreader.

Suitable for Single-Slot Expansion

Owners of a compatible dm4 notebook who have a free SODIMM slot can add 4 GB of capacity with this JEDEC-standard part. Systems that already populate every slot, or that require ECC or registered memory, cannot use this non-ECC unbuffered module. Buyers needing more than 4 GB per slot should look for higher-density modules.

204-Pin DDR3 SODIMM Form Factor

The 204-pin DDR3 SODIMM interface is the sole specification that decides whether this module fits your machine. If the dm4 service manual calls for 204-pin DDR3 non-ECC memory at 1.5 V, this part matches; otherwise it will not seat or function.
