The 20 macbook pros allow for 1333mhz what did they change in the 2010 mbp?

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. I am very new to apple and what I think is going on is the firmware is blocking the FSB from running at 1333mhz. I called apple and he told me to do a smc reset that was the only thing I could try. 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 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 a 2009 2.53 15' and 1333mhz chips work fine I have 2 kinds Crucial and Mushkin. So once again this contradict what you said ' Plus like all Mac's, the Mac Mini's are very picky and will only run on modules that are specifically designed for Mac's.I want to upgrade my mid 2010 13' Macbook pro to 8gb 1333mhz. VMWare Fusion gives me readings of 1300Mgbs speeds when reading the Samsung SSD used as the hard drive for the virtual machines It is something to keep me occupied and on another thing if my 16Gb Ram currently installed on my Mac mini 2012 and as you said it yourself for Mac to be picky both my memory module are from Crucial therefore working fully and I also talk about the 1 x 2TB Samsung SSD and the other which is a x 4TB Samsung SSD both installed on the Mac mini 2012 all of what I mentioned here are not Apple products yet they all work perfectly. I wait for the memory modules to arrive since it does not cost me anything to try since I can always return them for a refund. Intel's specifications tell another story.
