In Core 2 Duo days I overclocked the FSB of my E2160 Pentium CPU by 50%. This boosted the frequency from 1.8 to 2.7.
These days I am happy I got my 14700K boost to 6200 MHz on single and dual core loads and to 5600Mhz P-cores and 4400 E-cores in multi-core loads. According to benchmarks this means about 10% performance gains. But it took me a week fiddling with BIOS settings and testing.
I was in high school, rocking an E2180 with a massive Scythe Ninja cooler. Had a 3.2Ghz "summer" OC profile and a 3.45Ghz "winter" one. Those were the days.
My cousin had an E2160 running at the same 2.7Ghz, and a Radeon HD3850 that was softmodded to HD3870. This PC is still running, and it's still overclocked!
