HP ProOne Compatibility

This 4GB DDR4 2400MHz SODIMM is built for HP ProOne 400 G3, 440 G4, 440 G5 and 600 G3 all-in-one desktops. It suits office users and IT teams who need a straightforward capacity increase for everyday multitasking. The module follows JEDEC standards and runs at 1.2V without ECC or buffering. Buyers with other HP models or non-HP systems should verify their exact part number before ordering.

Thermals and Power

The stick operates at the standard DDR4 voltage of 1.2V and carries no heat spreader, relying on the chassis airflow of the supported ProOne units. Under normal office workloads the module stays within JEDEC thermal limits and adds negligible acoustic load because it has no active cooling. Power draw remains consistent with other 260-pin PC4-19200 CL17 modules of this density.

What the Extras Change

The package includes only the memory module itself; no installation tools, cables or software discs are supplied. OWC provides a limited lifetime warranty with an advanced replacement option and free technical support, which simplifies the process if a defect appears. Their in-house validation testing aims to reduce the chance of a dead-on-arrival unit, but the upgrade experience is otherwise identical to a bare JEDEC SODIMM.

Questions about this item

How do I install this 260-pin SODIMM into an HP ProOne 440 G5 and what step is often missed?

Power off and unplug the system, open the access panel, align the notch on the module with the slot key, press firmly until both side clips click, then reseat if the system does not POST on first boot.

What maintenance or replacement will this 4GB DDR4 2400MHz CL17 module need over time?

No scheduled maintenance is required; if errors appear in memory diagnostics or the system becomes unstable, replace the module with an identical 1Rx8 1.2V part.

What limit appears first when this CL17 1.2V SODIMM runs sustained workloads?

The CAS latency of 17 cycles at 2400 MT/s sets the access timing ceiling, so sustained bandwidth is bound by that latency figure.
