How to determine my CPU FSB? Looking to buy new MOBO Tags: CPUs Support How To Product Last response: May 1, 2012 11:08 PM in CPUs Share thefamous1 May 1, 2012 10:57:18 PM Hey, I am looking to purchase a new motherboard that can give me more overclocking options and support more RAM. I was looking at: http://www.newegg.com/Product/Product.aspx?Item=N82E168... and I saw that it says, "Note: FSB800 CPU only support DDR3-800" My current CPU is a Q9550, and I know when I go into the BIOS I see that the FSB is 333, but what does it mean by a FSB800 CPU - and how can I determine if my CPU is a FSB800 CPU or greater?
