i had 2*2Gb DDR3 1066 Mhz on my Mid-2009 Macbook-Pro 13-inch. So i was planning to upgrade the ram to 8GB. So i tried to install the 8Gb DDR3 1333 MHz on MBP (from my 2010 iMac)but it started with 3 beeps. So then i put one 2Gb DDR3 1333 MHz in it and it booted properly. So finally i got a 4Gb DDR3 1066 Mhz and put 2Gb DDR3 1333 MHz along with it and its working properly. So wanted to know whether the problem is with installing 1333 MHz or with installing single 8Gb DDR3 1333 MHz. Plz help as i want to increase it to 8Gb instead of keeping it at 6Gb
