Probably a tie between two for me. First would be the E5-1650 at 5346MHz done with a 120mm AIO. Stayed the world record for just over two years before prices on these plummeted and some fancy fellows with chilled loops decided to compete. Very fun chip in general.
The second in this tie is my original Phenom II X4 960T, unlocked to an X6 1605T, at 4420MHz turbo with all cores active. This CPU ran at 4GHz for most of its life when I used it, so I was happy to see after 8 years that it still had something left to give.
