Questions about this item

What type of memory slot must my HP Pro 3420 AIO have for this 204-pin DDR3 SODIMM to fit?

The system needs a DDR3 SO-DIMM slot that accepts 204-pin modules running at 1.5 V.

Will this PC3-10600 CL9 module run stably if I keep an existing 1333 MHz stick in the second slot?

Yes, both modules will operate at the shared 1333 MHz speed and CL9 timing when paired in the HP Pro 3420 AIO.

How can I confirm the 2 GB module is recognised at the correct 1333 MHz speed after installation?

Check the system BIOS or Windows Task Manager memory tab; it should show 2 GB running at 1333 MHz.
