    Im still running stable on 12gb, for the meantime run either one 2gb module and one 8gb module, or a 4gb and 8gb together, I promise it will boot and run without issues, albeit a bit slower due to the lack of ram hyperthreading ( Mismatched modules)

  • hackintosh1800 Level 1 (0 points)

    Interesting turn of events. So , i decided to switch the order of the two 8gb modules, put the top one in the bottom and the bottom in the top...

    Windows 7 64 bit now runs with no crashing or issues, and sees a full 16gb of ram Minus the videocard ( screenshots coming)


    OS X 10.8 does not boot with both 8gb modules installed or one 8gb module. Windows 7 boots with one 8gb module by itself.


    Long story short I am typing this in windows 7 with 16gb ram on a 2010 13 inch mbp... I opened up steam , LA noire, Sonic Generations and half life 2 episode 2 , no crashes even under gaming load..


    This is definately a soft block, not a hardware limitation to all the nay sayers, otherwise why the heck would windows 7 fully run 16gb with no freezing or crashing.


    That being said, the newest efi for the 13 inch 2010 mbp does NOT solve the issue, I am actually wondering now that I reversed the modules, if the an older EFI version would allow os X to boot with 16gb installed.



    Anyone know how to downgrade EFIs?

    I have tried desperately to find this info, but to no avail.   It is in sombodys user tips.  I can't for the life of me figue out who,  Checked everthing I could think of. Sorry.

  • Benjamin2102 Level 1 (100 points)

    ok, finnally found it not sure if this helps.

  • Ja'a Level 1 (0 points)

    Okay, so I tried the 12g method and it didn't work for me.  Do I need to have them in a particular order??

  • Ja'a Level 1 (0 points)

    I've tried switching the ram around and it is not working for me in either order...this *****!!!

    GUYS!!!! I now have 16gb working 100% in my 2010 mbp. OWC ( other world computing) sells a 16gb kit 1066mhz @ 99$ for the Mid-2010 MBP 13" I bit the bullet and got it, works FLAWLESSLY!


    Pros: Lifetime warranty, dual channel, works without mods plug and play, windows 7 64bit and 10.8 both work without slowdowns and hiccups. The performance difference is really noticable in 10.8!!! No more slowdowns once in a while ( stock 4gb ram slows down every couple of minutes in 10.8, very noticeable when web browsing, 8gb does not do this however, you can feel a difference with 16gb , meaning 8gb gets clogged rather quickly as well too. I HIGHLY recommend this kit!!!!

    Cons: 100$, but well worth the extra $40 considering the saved headache!!!!


    Thus, in conculsion, DO NOT BUY CHEAP RAM off ebay. Only branded products like owc, or PNY, or others, the first 16gb kit I got was not branded and thus not very compatible. ( works fine in my acer core i3.)


    Myth BUSTED. 16gb ram DOES WORKin a mid 2010 macbook pro 13" with the nvidia 320m chipset and a core 2 duo 2.4ghz. This means the mac mini with the same chipset SHOULD support it as well!!!!!

  • hackintosh1800 Level 1 (0 points)

    Yes you do, however it doesn't work in dual channel. Get rid of the kit you got, and get the OWC kit, it will work if you have a 320m 2010 13"er

  • ceejay3k Level 1 (0 points)

    This is awesome!!! Now if only someone is able to conclude that the same kit will work on a mid-2010 17" MacBook Pro then I will be in business!

  • Digitalclips Level 1 (0 points)

    I wonder if my mid 2010 15" i7 MBP would run the same kit successfully?  I don't see it mentioned as being able to at OWC's web site.

  • hurkan Level 1 (0 points)

    Seems like we are going to get what we want. OWC has listed the 2010 13" mbp as compatible for their 2x8GB 1066MHz bundle. Hopes are high for the 17" i7's out there. Keep posting friends.

  • Digitalclips Level 1 (0 points)

    I only see a MacBook 13" 2010 model at 16 GIGs not a MBPro they are all at 8 GIGs.  Can you post link?

  • hurkan Level 1 (0 points)


    This OWC Memory is compatible with...

    MacBook Pro (13-inch Mid 2010)

    (April, 2010)

    Model ID: MacBookPro7,1

    2.4GHz, 2.66GHz



  • hackintosh1800 Level 1 (0 points)

    Guys, if it runs on a 13" with the 320m, it will run on the 17" with the 320m or on a c2d 2.6ghz etc etc.


    I bit the bullet, heck , just do it, and post results, if it doesn't work, rma!!! Or email owc first! The ram they sell is matched identically in specs other then size as to what the mid 2010 uses, so if your computer uses the same ram (1066mhz) there should be NO REASON why this kit would not work. The cheap ebay kits, thats another story!!!! Looks like the EFI does not have a soft block built in for capacity. The only issues are that the ram must be matched perfectly to what was stock. So, CL3, non ecc, non buffered etc etc. As long as all specs match and its a branded kit, it should work! Personally, the owc kit is not that much more $$, so i said screw it no more hassle and got it.
