Compatible DDR3 SODIMM for HP EliteBook 8770w

This OWC module is a 4 GB DDR3 1600 PC3-12800 CL11 1Rx8 204-pin 1.5 V non-ECC SODIMM built for HP EliteBook 8770w and 9470m notebooks. It is a new, JEDEC-standard upgrade tested to meet OEM specifications. The unbuffered design installs in a single slot without tools. Buyers needing ECC error correction or registered buffering should look elsewhere.

4 GB capacity handles everyday multitasking

A single 4 GB stick adds comfortable headroom for web browsing, office suites and streaming media on supported EliteBook models. The DDR3 1600 speed matches the platform’s native memory controller for stable operation. Performance tapers off when running virtual machines, large creative projects or modern games that demand 8 GB or more. Systems limited to one SODIMM slot cannot expand beyond this module.

Replaces factory 2 GB

Swapping a 2 GB stick for this 4 GB module doubles usable memory and reduces swap-file thrashing on 8770w and 9470m units. The upgrade is worth it when the laptop currently stutters with several browser tabs or document windows open. If the system already runs 8 GB or 16 GB in dual-channel mode, adding this single stick yields little benefit. Matching speed, voltage and rank is essential; mixing dissimilar modules can cause instability.

Questions about this item

Will the 1Rx8 DDR3 1600 CL11 module run with the original PC3-12800 sticks already in my HP EliteBook 8770w?

Yes, the module matches the DDR3 1600 PC3-12800 CL11 1.5V specification of the factory memory, so it will operate at the same speed and timing when installed alongside existing sticks.

How can I confirm the 204-pin SODIMM is detected at the correct 1600 MHz speed after installation?

Open Task Manager or a system information utility and verify the memory slot shows 4 GB running at 1600 MHz with CL11 latency.

Does the box include only the 4 GB 1Rx8 SODIMM or are tools and a heat spreader also supplied?

The package contains the single 4 GB 204-pin DDR3 SODIMM module; no installation tools or heat spreader are included.
