HP 450 and 1155 DDR3 SODIMM upgrade

This 4 GB DDR3 1600 CL11 module fits HP 450 and 1155 laptops using a 204-pin SODIMM slot. It is a single 2Rx8 unbuffered non-ECC stick rated at 1.5 V and built to JEDEC PC3-12800 specifications. The module adds capacity without requiring any firmware changes.

Sustained load behaviour

At the rated 1600 MT/s and CL11 latency the module delivers steady throughput for everyday multitasking and larger file handling. JEDEC compliance ensures stable operation during extended sessions without voltage drift. The 2Rx8 organisation helps maintain bandwidth when multiple applications share memory.

When the upgrade makes sense

The jump is worthwhile when the system currently runs on a single lower-capacity stick or when the factory configuration leaves a slot empty. It will not help buyers who need more than one module to reach a higher total capacity or who require ECC error correction for data-integrity workloads.

Questions about this item

Does the 1.5 V DDR3 1600 module run hot or draw extra power during long sessions?

It operates at the standard 1.5 V JEDEC voltage with no heat spreader, so power draw and thermals stay within normal DDR3 limits for a 4 GB SODIMM.

What must the laptop already have to accept this 204-pin SODIMM?

A free DDR3 SODIMM slot that supports PC3-12800 speed and 1.5 V operation, as found in the HP 450 and 1155 models.

Will this CL11 2Rx8 stick work beside an existing 1Rx8 module in the same HP 450?

Yes, the module is JEDEC-compliant and unbuffered, so it can run alongside a single-rank DDR3 1600 SODIMM at the same voltage and speed.
