What was your first experience at overclocking?

An Intel Northwood Celeron 2.2Ghz on stock cooling. It was on a standard jetway POS board but still hit 2.72Ghz without any issues. I didn't stress test it or anything though so I have no idea if it would have been ok 24/7.

I ended up leaving it at 2.5Ghz.
 
I am trying to think if I overclocked anything before my AMD K6-2 400. I didn't realise when I got it that I had one of the first stock in the country as review sites contacted me for a write up!
 
Jan 1997 : P166 to 180 MHz; best it would do on stock cooler.

Then

- Celeron 300a to 450
- AMD Athlon slot A 550 to 800
- Intel e2140 1.6GHz to 4GHz
 
AMD 2500-M+ Barton
512mb BH5
Abit NF7-S v2

Think i had 2.5GHz (stock was 1.8GHz) stable but could bench at 2.7GHz

Super pi 1M time was around 37 seconds :) (top cpu at time was the xp3200 which was about 48s super pi 1M iirc)
 
Mine was an Amd Thunderbird i think, but after that the same set up as you postmanfw pretty sure it ran at 2.8ghz tho :)
 
Athlon XP Got into it rather late, but started off with water cooling right away on the old dangerden stuff. I guess i was lucky since they were the magic chips that would double their mhz.

My first, was a 486-DX25 that I overclocked to 40Mhz by replacing the motherboard clock crystal.

Same for me but I am sure it was from a 486sx25 to a 33 by replacing the crystal. Maths co-processors were not even in the cpu die package back then and no mmx or media type stuff included either.
 
I seem to remember fiddling with the on-board switches of the motherboard for my AMD K2. But the first I remember, and the first done properly, was a 850MHz Slot A Athlon. First job was getting the casing off without ****ing the processor. I had no money left to replace it if I managed to break it, so levering the cover off with a bradawl was fairly scary. I managed to put the tip of the bradawl right through the end of my thumb doing it, and all I cared about was not breaking the processor.

I then fitted a GFD (can't remember which one), and instilled (IIRC) MAthlon, so I could play with the L2 cache multiplier. I got the thing to 1016MHz stable IIRC.
 
P200 MMX to 225MHz, via bumping the bus speed to the Cyrix 75MHz setting. Unfortunately it was one that didn't recognise the 3.5x multiplier so no 233MHz.

One of the very early jumperless TX chipset boards, can't recall the manufacturer.
