I tried booting with both sticks of ram in and got 3 beeps and error code 15. I tried again with only one stick. I tried each slot with just at one stick, then tried each slot with just the other stick. Same result.

I just placed the CPU in so I know there's no bent pins or anything. I just installed this mobo and this is my first boot with it. I read that I may be because I have a newer gen CPU but I'm hoping that's not the case.

Any idea what's up?
