well it is possible that your MoBo bottlenecks your CPU...

did you flash the newest BIOS? // ps new BIOS will come late Jan or Feb

can you improve your cooling? what about a slight undervolting?

I think so. I only see people reaching 22k with PBO on. 

Same for me. I almost reach 22k. Without it, I have almost the same score as you.
