I just wanted to make sure it was compatible and did not require a bios update. 1 guy at microcenter said it might, but two others said it will work. just wanted to make sure
As long as it gas bios rev f12 or newer you'll be fine. Why are you putting an unlocked k cpu on a board that can't utilize to its full potential? K cpus are designed for overclocking and the b85 is a non overclocking board. If you want to oc you need a z87 or z97. If you are not overclocking just get a cheaper(usually cheaper)non k 4690.
Possible that rev was released after devils canyon and will more than likely work. If the K is cheaper I guess why not. I wish I was near a microcenter, they do tend to have great cpu prices but are in store only deals.
