OWC 3S2D41R808GB 8GB DDR4 3200 CL22 SODIMM memory upgrade

Targeted HP ProOne upgrade

This 8GB DDR4 SODIMM module is built for HP ProOne 400 G6, 440 G6, 440 G9 and 600 G6 all-in-one systems. It delivers 3200MHz speed with CL22 latency at 1.2V using a 260-pin unbuffered non-ECC design. The module suits office workers and IT teams who need a straightforward capacity increase for daily multitasking.

Replaces slower or smaller DDR4 SODIMMs

The upgrade makes sense when the existing ProOne ships with 4GB or a lower-speed DDR4 stick and the board has a free slot or can accept a larger single module. Moving to 8GB at 3200MHz PC4-25600 lifts throughput for browser-heavy workloads and larger documents. The jump is not worthwhile if the system already runs matched 3200MHz modules at maximum supported capacity.

Check slot count and maximum capacity

Verify how many SODIMM slots your specific ProOne model provides and what the manufacturer lists as the maximum supported memory per slot and in total. Confirm the current installed speed so the new module can run at its rated 3200MHz without downclocking. Ensure the BIOS is up to date for full compatibility with 1Rx8 8GB density modules.
