    Hello, I have a macbook pro with 2.4 core 2 duo and a 250 SSD, and 8 GB RAM ( 2 x 4GB). The thing is every time i do a Mac hardware test with the DVD it came with I get this Error code 4MEM/1/40000000: 0x7c46a990. I have 2, 1 gb ram also and when i combine 1 gb and a 4 gb ( i try to combine all different ways) I dont get and error code i only get the code when the two 4 gb are together:confused: when i was using 8 gb I was having alot of Kernel panics and SHUT DOWN messages, i will wait and see if i get anything with 5 gb:(:apple: Please help me? thanks in advance

    just a wild guess, could be the 4 gbs are not identical like latency etc? or maybe you have exceeded the max installable capacity.

    Might be the RAM itself, would not usually go for PNY ram. Kingston, Corsair, or Crucial.

    Sounds like one of the RAM sticks may be the issue. I'd recommend Crucial RAM.
