HP ProBook 450/455 DDR4 upgrade

This 16 GB kit uses two 8 GB DDR4 2400 SO-DIMM modules built to 260-pin form factor. It targets owners of HP ProBook 450 G3, 450 G4, 455 G4 and 455 G5 notebooks that accept DDR4 memory. Each stick runs at 1.2 V with CL17 timing and unbuffered, non-ECC operation.

Not for non-listed models or ECC needs

Buyers with laptops outside the listed ProBook part numbers should verify compatibility before purchase. Systems that require ECC registered memory or a different pin count cannot use this kit. The modules are unbuffered and non-ECC by design.

Steady throughput at CL17 1.2 V

Under sustained load the pair maintains DDR4 2400 transfer rates at the rated 17-17-17 latency without voltage increase. The major-brand chipset and 2Rx8 organisation deliver stable bandwidth for typical multitasking and productivity workloads.

Questions about this item

My ProBook 450 G3 has two DDR4 SO-DIMM slots — will this 2x8 GB kit fill them both?

Yes, the kit provides two 260-pin DDR4 SO-DIMMs for a total of 16 GB, matching the two-slot maximum of the compatible ProBook models.

If I keep one existing 8 GB DDR4 2400 module and add one stick from this kit, will the system run in dual-channel?

Dual-channel requires matched capacity and timing; mixing a single 8 GB stick from this CL17 kit with a different module may force single-channel operation.

After installing both sticks, how do I verify the memory is running at the rated 2400 MT/s with CL17 timings?

Enter the BIOS or use a system-information utility and check that the memory frequency shows 2400 MT/s and the timings read 17-17-17.
