27" iMac Purchased end of November 2013
Purchased an i7, 27" iMac with 8GB Ram (4GBx2). Have not received the iMac as yet, still being shipped to local retail store. I am having second thoughts about increasing the Ram. Can I mix the Ram - original (4GBx2) and additional (8GBx2) and use all four(4) SO-DIMMs? I realize the specs of the Ram must be the same.
iMac, OS X Mavericks (10.9)
