I've owned A LOT of CPUs in the past. 95% I've bought with the sole purpose to overclock them. All of these were my primary system CPUs at one point. I've only had one complete system at a time if you can believe that.

Pentium 166C to 180 = 8.5%
K6-2 300 to 333 = 11%
Celeron 300A to 450 = 50%
Celeron 300A to 464 = 54%
Celeron 366 to 550 = 50%
Pentium III 450 to 600 = 33.3%
Pentium 500E to 700 = 40%
Pentium 500E to 750 = 50%
Pentium 650 to 910 = 40%
Pentium 650 to 1021 = 57%
Athlon TBird 1GHz to 1.15GHz = 15%
Athlon TBird 1.2GHz to 1.25GHz = 4.2%
Athlon TBird 1GHz to 1.35GHz = 35%
Athlon XP 1600+ 1.4GHz to 1.5GHz = 7.1%
Athlon XP 1800+ 1.53GHz to 1.6GHz = 4.4%
Pentium 4 1800 NW @ 2520MHz = 40%
Pentium 4 2000 NW @ 2667MHz = 33.3%
Pentium 4 2400C @ 3120MHz = 30%

Intel 12 CPUs = 40.51% average overclock
AMD 6 CPUs = 12.78% average overclock

So, whats your CPU overclock history?

i overcloced a p1 133 by mistake once setting the jumpers wrong!

my first one i tried to do was the nice 550e. dont remember exactly how high i got it.

now im running a 3.0 and get it as high as 3.6

PII450 @ 500

I would love to o/c this 900MHz celeron but unfortunately it can't be overclocked =/ (as far as I know)

Amd tbird 750 to 845 = 13%
Amd tbird 1100 to 1200 = 10%
Amd tbird 1400 to 1575 = 13%

P4 1.8a@2.4 (1.65v) = 33%
P4 1.6a@2.74 (1.71v) = 71%
P4 1.8a@2.61 (1.68v) = 45%
P4 2.4b@3.24 (1.6v) = 35%

All but one are still living today and believed to be running at same speed....

486DX/33 to 50MHz :)
AMD K6-200@250 (wow that thing ran hot... until I stuck on a big fan:))
Celeron 300A@504
Celeron 300A@558
Celeron 366@616
Pentium-III 600@~800
P3-700@1084
P3-700@1050
P3-700@1015
Celeron 700@826
Duron 600@900
TBird 1.2GHz@~1.5GHz
TBird 1.4GHz@1.684GHz
AthlonXP 1800+ (1.53GHz)@1.70GHz
AthlonXP 2000+ (1.67GHz)@1.775GHz
AthlonXP 1700+ (1.47GHz)@1.6GHz (non Tbred-B)
AthlonXP 1700+ (1.47GHz) TBred-B@2.34GHz@1.55V (haven't pushed up voltage more yet; don't think I will)


EDIT: Oh, also a TI-83 overvolted; ran a random number generator thing on it... and it was faster than a stock TI-83. Quite possibly the most useless overclock ever :)

Wow. There's been quite a few, but here are highlights:

2 x Celeron 300A to 450 (BP6)
2 x Celeron 366 to 550 (BP6)
Celeron 400 to 500
Pentium III 500 (Katmai) to 630
Pentium III 600E to 750
Pentium III 700E to 1.0
Athlon TBird 1.3GHz to 1.50GHz
Athlon TBird 1GHz to 1.33GHz
Athlon XP 1600+ to XP 2100+
Athlon XP 2100+ to XP 2700+

I know I've forgotten some, but that's not too bad a list.

550E @ 825 50%
650e @ 910 50%
1.8a @ 2.90 61%

My list would be way to long to post - I've owned hundreds of computers.

But here's my first overclock: I replaced the clock chip which ran at 4.7Mhz, and I replaced the 8086 chip with a 8088-2, and turbo'ed my first IBM PC clone (Not PC-XT!) to 8Mhz, in the early 80's!

One other system of note: an AMD 486-100 running at 133Mhz. I mention this one because I am still using it! It's a packet filtering router with just a floppy and a couple of 100-Base-T cards in it.

Heh. Ahhh... the good 'ol days of changing timing crystals on like.. 8088's and 286's and 386's. haha... funny. i remember I even used a stack of pennies as a heat sink for my 386sx-16@25!

I still have my 386SX 16 Mhz... still works too... I should put a hard drive back in it and fire it up and laugh at how slow it is.

The first and best overclock processor was:

486SX-25 25MHz oc to 50MHz, 100%.

I did not get anything close in performance until the P4 Northwood:

P4 1.6A 1.6GHz oc to 2.72GHz, 70%.

In between, most Intel CPU can manage 30-50%. I had only one AMD, K6-200 and it hardly oc at all.
