Hi, I read that unofficialy the IMAC support 32 GB di ram. So I ordered to crucial 2X8GB kit, and added to my IMAC to have in total 20GB. Everything looked fine, until I started to work heavily with Adobe Premier. In fact during the edit my Imac started to have randomic Kernel Panic attacks! So i tried To remove the 4 GB and everything looks fine, I mean no panic attack anymore. What do you think the problem is? 1) Imac is not stable with more then 16gb di ram 2) the brand of the ram are different, so they are not really compatible. Any experience about this? I would love to have more Ram, so if the problem is the brand compatibility, I will order more from crucial hoping that now it will be compatible. Thank you.
