Would this RAM work on my iMac?

[westerns]

Hey Guys!

I've been doing a lot of reading about the best RAM to use to upgrade my mid 2011 21.5 iMac...

I know a lot of people on here reckon Crucial is pretty much the best bet, so I went on their site and did the system selector thingy and found this one...(I'm after 2x8GB sticks)

Is that the same as these ones on Amazon? They do look the same to me but admittedly i'm not too hot on these things so I wondered if any of you guys had bought these...

Quite a bit cheaper on Amazon so i'd rather go that route if they're the same!

Thanks for any helpers out there!

On Amazon it has this Item number:

CT102464BF1339

And on Crucial:

CT3373714

Visually they also differ.

But, they should work I think.

Not much cheaper though, about £20 cheaper.
