OWC 16GB DDR4 3200 SODIMM for HP ProBook

This 16GB DDR4 3200 CL22 SODIMM is built specifically for HP ProBook 445 G9, 450 G8, 450 G9, 455 G7 and 455 G8 laptops. It provides a straightforward memory upgrade for users who need more capacity for multitasking and larger workloads. The module follows JEDEC standard specifications at 1.2V and uses a 260-pin unbuffered non-ECC design. Buyers whose systems require ECC or registered memory cannot use this module.

Thermals noise and power at 1.2V

Operating at the standard DDR4 voltage of 1.2V, the module draws minimal power and generates little heat during typical office and browsing tasks. With no heat spreader fitted, it relies on the laptop's internal airflow, which is sufficient for normal use. The low voltage helps preserve battery life in the compatible ProBook models. Acoustic impact is negligible because the memory itself has no moving parts.

Behaviour under sustained load

Under continuous heavy workloads the CL22 latency and 3200MHz speed deliver steady throughput within the JEDEC PC4-25600 rating. The 2Rx8 rank organisation allows the memory controller to interleave accesses, maintaining consistent bandwidth over long sessions. Thermal throttling is unlikely at the rated voltage in the target chassis. Systems needing higher frequencies or lower latencies will not reach those levels with this module.
