A:Answer It's in the manual, and I'll tell you there is one available, if you can get it! I received this PC 1 week ago. I went into Best Buy the next day and told the person that helped me I just bought this PC and wanted to add 16gb ram. He obviously had no idea and he sold me ram that is not listed as compatible with this motherboard. You better get something to monitor your system especially for heat, from what I read heat is a major issue along with basic quality issues. Check YouToob, good luck.
