This single 4 GB DDR3 1600 CL11 module runs at 1.5 V and fits the 204-pin SODIMM slot found in HP ProBook 6450b, 6455b, 6550b and 6555b notebooks. It is a non-ECC, unbuffered 2Rx8 part that meets JEDEC and ROHS standards for a warranty-safe upgrade.

Suitable for owners of the listed ProBook models

Buyers with other laptop models, systems that require ECC or registered modules, or anyone needing a higher density stick should look elsewhere. The module is not compatible with desktop DIMM slots or platforms that demand a different voltage or pin count.

4 GB capacity per module decides fit

Only one 4 GB stick is included, so the total added memory equals 4 GB. Verify your ProBook's maximum supported memory and available slots before purchase to ensure this capacity matches your upgrade plan.
