Hello everyone,
It's my first post on MacRumors, so if the place for the post is wrong by any chance, please let me know - i'll repost it immediately.
I bought 2x4 GB DDR3 Corsair MacMemory RAM (CL7 1066 MHz) a couple of days ago and replaced the factory default 2x2 GB memory just after the package arrived. At first attempt the computer didn't boot, all i got was a power LED flashing along with 3 succesive beeps (as I googled, it indicates RAM didn't pass a data integrity check). I turned the computer off and at the next attempt it booted properly, and the new RAM was detected by the OSX. I thought it was the end of all the problems, but the whole thing starts over and over again if i try to boot the computer after the system has been shut down and the computer was powered off. I usually takes 2-4 attempts until I get it to work properly. Also, when try to wake up the Mac from Sleep mode (it usually happens when it has been asleep for a few hours) it doesn't respond - I have to power it off manually and then play the whole booting game from the beginning.
My question is: is it faulty RAM, or maybe this is some system config issue that needs a fix? The machine is MacBook Pro Mid 2010, i7 2,66 GHz, 256 Samsung 840 SSD + 500 GB Seagate HDD, Snow Leopard 10.6.8.
Any help will be appreciated. Thanks in advance!
