Q: Ram upgrade problem

I recently tried to install another 4GB of ram to my iMac. Everything seemed to go fine, I could see the extra ram in the activity monitor.

When the iMac went to sleep with the new ram installed it refused to wake up. I tried mouse, keyboard and power button to try and wake it. I had to turn off the power and start it up again.

I tried a NVRAM/PRAM reset.

 

The no waking problem was resolved by removing the ram.

 

iMac: 21.5-inch, Mid 2010, 3.2 GHz

RAM: Crucial 4GB DDR3 PC3-10600 SODIMM 204 Pin Memory Module

 

 

Could this be a case of bad RAM or am I missing something?

iMac, OS X Mountain Lion (10.8.5)
