Ram compatibility question

I found an amazing deal on some 16 gb ram sticks. But the guy wrote that it's "DDR3L SDRAM, DIMM 240-pin". And after my research i am still not 100% sure what he meant. 

So my question to you guys is:

Will this ram work with my P8Z77-V LX motherboard and my i7-3770K?

240 pins is standard atx to micro atx boards. It will fit. But check on your motherboard manual if it the brannd is compatible, best way to find out

Well the brand is Dell and i could not find it in the manual. But don't you think it would be a pretty safe bet with such a mainstream brand?
