HP EliteBook DDR4 SODIMM upgrade

This 4GB DDR4 module is built for HP EliteBook 830 G5, 830 G6, 836 G5, 840 G4 and 840 G5 notebooks. It uses the 260-pin SODIMM form factor and runs at 1.2V without ECC or buffering. The part targets owners of those specific models who need a straightforward capacity increase.

Sustained-load behaviour

The memory operates at DDR4 2400 (PC4 19200) with a CAS latency of CL17 and a single 1Rx8 rank. JEDEC compliance means the rated speed and timings are maintained during continuous workloads without relying on overclock profiles. OWC tests every module in-house to verify stability under prolonged use.

Deciding specification

Capacity is 4GB, which determines whether this stick matches your upgrade plan. If the target laptop requires a larger single module or a matched pair for dual-channel operation, this unit will not meet that need.
