Question 1

I wonder if this product fits a Lenovo IdeaPad N580?

Accepted Answer

When I question what type of memory to use.  I look at crucial.c0m and use their memory finder.  It gives the most accurate report as well as details about how many sticks can be used, max memory, etc...

Question 2

This memory is listed as 1.65V, yet the first line in the Overview says it operates on 1.5V.  Which is it?  Is it safe to use on a 1.5V memory controller?

Accepted Answer

YES, it is .
I bought this Team Elite 8GB ( 2 x 4GB ) and they work perfectly fine. 
However, the case packing of these memory look cheap.....if you wanted they look great, buy the CORSAIR Memory brand but it is more expensive !

Question 3

unbuffered?

Accepted Answer

Usually, unless it specifically states that it is buffered/registered, then it would be unbuffered.

Question 4

Is this non-ecc memory?

Accepted Answer

Yes if it says "Desktop Memory" then it's not ecc. Ecc is for servers. Even servers can take non  ecc memory.
