I'm about to buy a Mac mini "Core 2 Duo" 2.26 (Late 2009) for a very good price. Right now it just has 2GB of RAM in it. I have 8GB of PC3-12800 RAM that I have laying around that is two 4GB sticks. The Mac mini uses PC3-8500, officially maxes out at 4GB, but you can use up to 8GB if you apply this http://support.apple.com/kb/DL888 firmware update. So my question is, can I use the RAM I have laying around for the mini? They are both DDR3.
