Macbook Pro 7,1 mid 2010 1333mhz ram issue
I want to upgrade my mid 2010 13" Macbook pro to 8gb 1333mhz.
I have a 2009 2.53 15" and 1333mhz chips work fine I have 2 kinds Crucial and Mushkin.
I can use any one of the 4gb chips along with one of the samsung 2gb chips that came with my laptop and it works fine at 6gb.
I have seen on one forum you can zap the pram with one of the old chips and a 4gb and get it to boot with both 4gb chips but this did not work for me.
I called apple and he told me to do a smc reset that was the only thing I could try. This did not work.
I am very new to apple and what I think is going on is the firmware is blocking the FSB from running at 1333mhz.
What I need to know if anyone can help me is, what am I missing? Intel's chipset and C2D 2.4ghz or 2.66ghz work fine with a 1333mhz FSB. The 2009 and 2008 macbook pros allow for 1333mhz what did they change in the 2010 mbp?
I am running efi 2.0 firmware and OSX 10.6.6 do I need to downgrade my firmware or mod my firmware to allow this to work. I am really upset that software is limiting my hardware speed.
Cheers,
