need help with ram

[Odoylerules16]

can i mix ram, i have 1600 mghz, samsung ram that the hp 500-314 came with.
can i just buy one more stick of 8gb with the same speed or do i have to buy 2 whole new sticks

I would suggest you buy two more sticks. The ram specs have to be identical or the system probably wont boot and it is unlikely you will be able to find the exact same ram that is already in your computer.

Get new DRAM and check it's on the HPs supported list, those pre-builts can be very picky and with a locked BIOS you can't make adjustments
