Question about memory for a Dell

[Jim]

Recently I bought a Dell Optiplex 7010.  Today I started looking for 
some more memory (2 4GB DIMMs) to put in it.  Some said it was for the 
Dell while others didn't claim to be for a specific model.   I did 
notice that the ones claiming to be for a Dell were about twice the cost 
of those that didn't and I don't want to pay the extra if I can avoid 
it. I'm sending links to a couple of the choices.  Can someone tell me 
if there's any difference between the two? Thanks.
