OWC 4GB DDR3L 1600 SODIMM Module

This OWC module is a 4GB DDR3L 1600 (PC3L-12800) CL11 1Rx8 204-pin 1.35V Non-ECC SODIMM. It is built to JEDEC and ROHS standards for a warranty-safe upgrade. The single stick is designed for compatible HP ZBook mobile workstations.

Ideal for ZBook G2 owners needing more memory

This upgrade suits users of HP ZBook 15, 17, 14 G2, 15 G2 and 15u G2 models who want to open more apps and larger files. Builders repairing other laptop brands or desktops should look elsewhere because the module is validated only for the listed systems. Anyone needing ECC or registered memory cannot use this part.

204-pin DDR3L SODIMM form factor

The module uses the 204-pin DDR3L SODIMM interface required by the target ZBook models. A system expecting a different pin count, voltage or memory generation will not accept it. Confirm the slot type before purchase.

Questions about this item

How do I install the 204-pin DDR3L SODIMM in my HP ZBook 15 G2 and what step is often missed?

Power off, unplug the AC adapter and remove the battery if accessible. Open the memory door, align the notch on the 204-pin module with the slot key, insert at an angle and press down until both side clips click. The step most people miss is re-seating the module a second time if the system does not POST on first boot.

What maintenance or replacement will this 4GB 1Rx8 module need over its service life?

No scheduled maintenance is required for the unbuffered non-ECC DDR3L SODIMM. If a memory error appears later, run the built-in HP diagnostics; a single faulty 4GB stick is replaced individually under the limited lifetime warranty.

What limit appears first when the 1600 MHz CL11 memory runs under sustained heavy load?

The 1.35 V DDR3L voltage ceiling is reached before thermal throttling becomes an issue, so sustained write-heavy workloads are limited by the JEDEC-standard voltage envelope rather than temperature.
