OWC 4GB DDR4 SODIMM for EliteBook 820 G3

This 4 GB DDR4 module is built for the HP EliteBook 820 G3. It runs at 2133 MHz with CL15 timing at 1.2 V. The 260-pin unbuffered non-ECC design fits the laptop's single SODIMM slot. Buyers who need more than 4 GB of capacity should look elsewhere.

Sustained workload behaviour

JEDEC-compliant DDR4 at 2133 MHz delivers steady throughput for everyday multitasking. The CL15 latency and 1.2 V operation keep power draw low during long sessions. Without a heat spreader the module relies on the chassis airflow, which is sufficient for typical office loads.

Build and installation

The bare green PCB uses a standard 260-pin SODIMM edge connector. No heat spreader means a low profile that clears tight keyboard decks. Installation is a tool-free DIY step: open the access panel, align the notch, press until the clips latch. The JEDEC and RoHS markings confirm a warranty-safe upgrade.

Questions about this item

How much heat or power does the 1.2V DDR4 module add when the EliteBook 820 G3 runs all day?

The module operates at the standard DDR4 voltage of 1.2V without a heat spreader, so it adds minimal heat and draws only the power required for a 4GB 2133MHz SODIMM during continuous use.

What must the HP EliteBook 820 G3 already have for this 260-pin SODIMM to work?

The laptop needs a free DDR4 SODIMM slot that accepts 260-pin unbuffered non-ECC memory at 2133MHz; the 820 G3 ships with such a slot, so no extra hardware is required beyond the module itself.

Will this CL15 2133MHz stick run correctly alongside the original memory already in my 820 G3?

Yes, it matches the factory speed of PC4-17000 2133MHz and CL15 timing, so it will operate in step with the existing module without down-clocking or compatibility issues.
