Have you called Dell Spare Parts directly (totally separate from Dell tech support) and given them that part number?
You can look at Crucial.com. They have 2x8GB RAM for this system model for ~$94. The good thing about Crucial is they guarantee it works in whichever system they recommended it for or they take it back. Many people around this forum buy from Crucial.
But do yourself a favor. Start at Crucial's home page and work through their product finder on the left side so you know you looking at RAM for your system. Don't just rely on the link I posted, because -after all- it is your money.
You will have to click the "Show more" button when you get to the page for your model to see the 8 GB modules.
And I guess you could sell the Hynix module on eBay etc to recover some of the cost of a new pair...
