I still have a 1700+ DLT3C sitting on my desk. I cut the traces and had it bumped to just over 2.5 GHz (from 1.47 stock) and ran the "wire mod" in the socket to bump up the vcore to make it stable.
I miss the old days. https://goo.gl/photos/t4SY4LEuZpFAgE6w9
Pentium Overdrive (I know this doesn't really count) @ 120 MHz
Celeron 300 @ 450
Celeron 900 @ 1.2
Athlon 2100+ @ not much over stock, it sucked
Athlon 1700+ @ 2.5 GHz
Barton 2500+ Mobile @ 2.6 GHz
A slew of Athlon 64, X2, and Opterons (in desktop boards) that I don't remember. Delidded a few of them and ran them bare die.
Q6600 @ 3.6 Ghz (caused fire to come out of my old DFI board, DFI replaced it because they were AWESOME and claimed fault that the VRMs committed suicide)
Phenom II X3 720 @ 3.6 GHz (unlocked to 4 cores)
Bulldozer FX 8120 @ 4.9 GHz - for 2 weeks till I sent it back since it was slower than the Phenom II in many games...
i7 2600K @ 4.8 GHz
i7 2700K @ 4.6 GHz (the 2600K died, the replacement wasn't so hot)
i7 4770K @ 4.5 GHz (delidded, very casual and low OC)
i7 6700K @ stock...for now. Needs delidded, will throttle at stock with a full custom loop.
