I finally decided to upgrade my ram from 8gb (2x4) to 32gb (2x16), but when I did, my iMac starts crushing all the time.. just to mention I left in the slots only the crucial rams and took out the apples ram.
Solved! Go to Solution.

Try one stick of new RAM at a time in one slot to see if one of the modules is bad. If one works and the other fails, then you have a bad stick of RAM and you can exchange it under warranty. If they both work or fail, then try them one at a time in the other slot. If both modules behave the same in both slots when installed one at a time, then I would contact Crucial Support directly to verify the memory you received is correct for your system and determine why it is failing in your system.
It doesn't hurt to blow some compressed air in the slot if there was dust around it.
I doubt if it would help, but I would also try an SMC reset, then power on the system & immediately do a PRAM reset before it boots (hear the chime 3 times or see the screen backlight flicker on & off three times (hard to see sometimes) just to be safe).
