    Hello everyone,

    I have got a 2010 iMac and it has 2x2GB samsung PC3-10600S-09-10-F2 (1333mhz DDR SODIMM) memory in it.

    Now I want to upgrade to 8GB of memory and I know there are many types of memory that will fit like some kingston modules and some hynix modules for example.

    However I do want to put the samsung memory in it because I already have it now (it looks nice to me:p). Now I was doing a little research and I found there are samsung SODIMMs (1333mhz) which have a little different type numbers.

    -PC3-10600S-09-10-ZZZ
    -PC3-10600S-09-11-B2

    The PC3-10600S-09-11-B2 memory has been used in some 2011 MBP's.

    But now I want to know what is the difference in the ram modules because the numbers are different but all are 1333mhz...

    Anyone?

    Thanks!

    Its most likely going to be the timing on the modules- the 9-10 should have lower timing which is better.

    and what would timing mean:confused: I don't know a lot about hardware.

    Laman's terms- how fast the RAM is at performing certain types of operations beyond just its clock speed (the MHz) - here's a good (albeit somewhat technical) breakdown of RAM timing and such- http://www.overclock.net/intel-memory/9981-ram-timing-explained.html

    Don't go OCD on timing and such, for lots of cases its' not a make or break end-of-the-world problem for most computer users.
