What was the best CPU for overclocking of all time?

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

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.

All i heard about back in the day was how well the E8400 clocked.

I weren't much of an overclocker myself, Never have been always kept at stock clocks on all my CPUs, But i do still have E8400 & Q6600 along with a few 775 Xeons in my collection.

Had them all.
Overclocking seems to have dumb down in the latter generations of CPU.


Edit:
Just remembered that I had an Athlon K7 550 slot style CPU with an Abit mobo that overclocked like a champ - was mighty toasty and noisy though :)

It was selecting the right motherboard that made it possible, I think - not all mobos at that time supported switching the FSB from 66 to 100mhz. But soon others picked it up

I’m very hazy about this as it was a long time ago now but for the Pentium 2 CPUs most motherboards must have supported the 100mgz FSB as the P2-450 required it. The more advanced motherboards supported more than just the 66 and 100mhz FSBs along with allowing changes to the CPU clock multiplier, separating the FSB soles from the memory speed and probably loads more I didn’t look at. Overclocking was fun back in the day :D
 
Q6600 has got to be up there as it was a good chip @ stock and could easily overclock by a very good percentage making it an absolute powerhouse of a cpu in its day.

Sure there are some lower powered chips that overclocked a bit better, percentage wise but thats only turning a rubbish cpu into a mediocre cpu.

Athlon XP I vaguely remember being good.

Q6600 I remember that being especially good value for money at the time. Made water-cooling worth it again.

After that Sandy Bridge was pretty good as well.
 
2500k, my old one hit 4.8ghz, even though I never hit that golden 5ghz, with modern cooling I think that it would have

  • TBird - reconnecting the L1 bridges with a pencil felt incredibly nerdy - one of the few CPUs i've kept. Although, the hormonal Abit motherboard that tried to tame it never survived. The only piece of hardware i've ever snapped...
  • 6600 g0 stepping - coupled with 'Heath Robinson' cooling over the northbridge. Again, another CPU that I've kept.
  • 2500K - a monster of a CPU. 4.8Ghz and ran flawlessly until retired as a server. Although the Silver Arrow was a baptism of fire that i stuck on top of it. The Ivybridge that followed never even got a glance...
