System-specific SODIMM for HP OMEN 15

This 4GB DDR4 module is built for the HP OMEN 15-ax209no, 15-ax209ns, 15-ax210nb, 15-ax210no and 15-ax211ng laptops. It uses a 260-pin SODIMM form factor and runs at 2400MHz with CL17 latency. The unbuffered, non-ECC design matches the factory memory specification. It is not suited for desktops or systems requiring ECC or registered modules.

Sustained-load behaviour

Operating at the standard 1.2V DDR4 voltage, the module maintains its rated 2400MHz speed under continuous workloads. JEDEC compliance ensures stable timing without voltage increases that could stress the laptop's memory controller. The single-rank 1Rx8 organisation provides predictable bandwidth for long rendering or compilation sessions. No heat spreader is fitted, so the module relies on the chassis airflow.

Deciding specification

The 4GB capacity is the single figure that determines whether this upgrade meets your needs. It adds one 4GB stick to a compatible slot, raising total memory by that amount. Buyers who need a larger single-module capacity or a matched pair for dual-channel operation should look for higher-density kits. The part number 2S4D41R804GB identifies this exact module for ordering.

Questions about this item

How much power does the 1.2V DDR4 SODIMM draw when the laptop runs all day?

The module operates at 1.2 volts, the standard low voltage for DDR4 SODIMMs, so it adds minimal heat and power draw during continuous use.

What must my HP OMEN 15 already have for this 260-pin DDR4 stick to work?

Your notebook needs a free 260-pin DDR4 SODIMM slot that accepts 2400 MHz PC4-19200 unbuffered non-ECC memory at 1.2 volts.

Will this CL17 2400 MHz module run correctly alongside the original memory in my 15-ax210nb?

Yes, it matches the JEDEC DDR4 2400 CL17 1.2V spec used by the factory memory, so the system will clock both sticks to the same speed and timings.
