Hi guys, i just got 2 x 4gb sticks of ram and when i put both sticks in my Mid 2010 MBP it got stuck at the loading screen. So i took out 1 of the 4 gb sticks and put 1 of my 2 gb sticks that came stock and it worked just fine. Computer boots up and reads the 6 gb of ram. I got the ram from best buy:
PNY - Optima 2-Pack 4GB (8GB Total) PC3-10666 DDR3 SoDIMM Laptop Memory Kit
http://www.bestbuy.com/site/pny-optima-2-pack-4gb-8gb-total-pc3-10666-ddr3-sodimm-laptop-memory-kit/4816107.p?id=1218533332124&skuId=4816107&st=pny%20ram&cp=1&lp=4
Has anyone else experienced this before? Is there something that i'm missing?

I had the same problem recently and there is a post about it. So the Mid-2010 are picky. I don't if it is all the MacBooks that have PC3-8500 modules (like the Mid-2010) are picky as well. One solution is flash one of the sticks to 1066 MHz. Another solution is to return and get the exact RAM speed. Sorry for the bad news. I was bummed about it too.

Yes... After a ton of researching I just found that out. (didnt see your post till after all my research, of course!) What did you end up doing? At my local best buy they dont have any ram that is only 1066 mhz. All the ram they have do both 1066 and 1333 mhz. I looked into flashing the ram, but the only software I could find that works is the Thaiphoon Burner. I got the free copy and got into my ram but it won't let me actually clock it to 1066 mhz unless I buy the full version. I dont want to spend $16 on it w/o knowing it will work for sure. I tried the SPDTool but it doesnt recognize my ram and it looks like its kind of old software. I couldnt find a current website to download it, only some mirror links.

Well, you can call around local computer repair stores if they have 8 gb PC3-8500 sticks. They would trade you since yours would be faster. I just sold mine and got my money back. What I read, that program works but I chose not to pay more money then I did.
