OWC 4GB DDR3L SODIMM for HP EliteBook

This OWC memory module is a 4GB DDR3L 1600 PC3L-12800 CL11 1Rx8 204-pin 1.35V Non-ECC SODIMM. It is built as a system-specific upgrade for HP EliteBook 840 G1, 840 G2, 850 G1 and 850 G2 notebooks. The module meets JEDEC and ROHS standards for a warranty-safe installation.

Suits owners of listed EliteBook models

The part fits the four EliteBook models named in the compatibility list and delivers a straightforward capacity increase for those machines. It will not work in systems that need a different form factor, voltage, speed or error-correcting configuration. Buyers with other laptops should verify their exact memory requirements before ordering.

204-pin DDR3L 1600 CL11 1.35V specification

The decisive specification is the 204-pin DDR3L 1600 CL11 1.35V Non-ECC SODIMM layout. Only notebooks that accept this exact electrical and physical interface can use the module. Matching these parameters confirms whether the upgrade is the right part for the target system.

Questions about this item

What is the CAS latency limit of this 1600 MHz module under sustained use?

The module runs at CL11 latency as specified by the JEDEC standard for DDR3L 1600 operation.

How much heat or noise does this unbuffered SODIMM add when the laptop runs all day?

The module has no heat spreader and draws 1.35 V, adding negligible heat and zero noise to the system.

Which slot type must the HP EliteBook already have for this 204-pin upgrade to fit?

The laptop must provide a DDR3L 204-pin SODIMM slot, as used in the EliteBook 840 G1, 840 G2, 850 G1 and 850 G2.
