8 GB RAM odd behavior

Hi Guys,

I've been reading this site for a while now, first time I'm posting.

I recently purchased 8 GB of RAM for my 2010 13" MBP. There are two 4 GB DDR3 PC3-10500 1333mhz sticks. When I install them in the laptop my computer does not get past the apple logo boot screen (the spinning disc freezes). However, I can boot into Windows (boot camp) without issues.

Also, when I pair either of the 4 GB sticks with one of my old 2 GB stock sticks the laptop boots up fine in OS X. The system profiler registers it as 6 GB of 1067 mhz RAM (the stock sticks are 1067 mhz)

Confusing...

Do you guys have any idea what the culprit could be?

Thanks

it's probably the 1333 mhz ram causing issues. mbps use 1066.

That hit the nail on the head. If you purchased it from anyone who directed you to believe that it is supposed to work in the MBP, then demand either a refund or replacement and do not accept 'you opened it so we can't do anything about it'.
 
Thanks for the tips.

I tried resetting the PRAM, no dice.

It's odd because I've read about a few people who have successfully used 1333 mhz RAM in their MBPs.

Also, I didn't want to create another thread for this, but any idea how the OCZ Agility 2 120 GB SSD fares compared to the more popular (in the forums) SSD models? (Intel X-25, OCZ Vertex etc.)?

It was worth a try. Its bizarre how it will recognise your new ram as long as you have a stick of the old ram in there.
 
yup, I just got in on a slickdeal and made sure to search this site for problems. Several 2010 owners complained about 1333 not working so I went with 1066 for my 8gb ram for cheap. ftw.

Same Problem With 1066MHz Sticks

I'm having the same problem with two 4Gb, PC3-8500 DDR3-1066MHz sticks as well. I installed two of these sticks in my MacBook Pro 13 inch (2010 model), but it wouldn't boot up. I then re-installed one of my old 2Gb sticks and the MacBook Pro booted and showed 6Gb memory under System Profiler. So this problem isn't just limited to 1333Mhz sticks. Does anybody know what's going on here?
