Q: Repeated kernel panic on iMac

Before I went on my summer holiday I added OWC memory to my iMac, as I understood from the way it was performing that it required an upgrade.

I returned to my desk today and have had 7 shutdown requests from my computer, the last of which is recorded below. I'm fairly computer savvy but am struggling to deal with this issue having spent the last 36 hours on three planes. HELP! Please...
