Very Low CPU Mark Score? Overclocked i5-7600K @ 4.8GHz

The result I'm getting is 7790, which is incredibly low for a 7600K, let alone one that's overclocked. The average score is 9301. I'm not even hitting 6600K average scoring?

Any ideas? I'm stumped. I've reran the test multiple times, closed all non-essential processes, restarted the PC...

I don't really care about the score so much as I'm worried that I'm not getting the right performance out of my PC.
