What was the best CPU for overclocking of all time?

[mark 11:11]

The old 800MHz (IIRC) Duron's used to overclock nicely with the help of a pencil

what was the thing with the pencil then? i obviously was too young/not into computers back then lol

 

[eeii]

The Pentium 4 pescott cpu was the funniest. Although not at the time. I remember many years ago doing an over clock thinking I was billy big bxllxcks its was stable I’m a god. Went to get something to eat and my mum screaming what’s that burning smell. Er that will be me then….. sorry another vote for the Q6600

Opteron 146 was a great clocker

Probably my 2500k. I had it running at 4.8GHz up from 3.3GHz for about 6 years before upgrading.

What a champ!

You used the pencil to draw a line to connect two chips or pins together to unlock the CPU. I did it myself on an Athlon 1Ghz to overlock it to 1.33Ghz but it was a very long time ago and I only did it once so the whole process is a bit hazy!

That wasn’t my best over lock though. I had a Pentium 2 300mhz that sat happily at 450Mhz on stock cooler. Saved a fortune with that trick. Just had to change the bus jumper from 66mhz to 100mhz! Then there was the 400Mhz Celeron that happily ran at 600Mhz on the stock cooler. Great times!

You used a lead pencil to bridge a trace line to unlock the multiplyers that were locked from factory with a broken trace.
It couldn't of been easier, literally draw from dot to dot on the 2 traces a lil straight line and you're done. Worked first time.
I had an 880MHz Duron running at something like 1.3 or 1.4GHz IIRC.
We used to get those Athlon 1800 or 2000XP's up to 2.4GHz too, but they lacked as much cache from memory versus the 2500/2800XP's.
