I thought he was talking about dual rank .VS. single rank memory?

I must have missed the 8GB part.

Yes I'm talking about single rank vs dual rank.  Confused if it takes dual rank. I have a 780 sff.  Currently only 3 gb 1 gb stick and a 2 gb stick. I bought the 780 off ebay.

I'm not sure about the 780; I do have a 790 (Q65 chipset ,core i5-2400) and dual rank (even 8gb modules) work fine.

Sorry as I did miss that in your original post. And I misread the Crucial site page. That would be 4 slots each holding a 4 GB RAM module for a total of 16 GB.

And this should answer the dual rank question.

It takes me a while but I usually catch my mistakes...
