What was your first overclock?

What processor did you first OC?

My first was an "Intel Overdrive DX40DPR75" (clock tripled 486dx, 25Mhz base clock). I ran it at 33 for a 99Mhz chip. around a 33% OC. I remember being amused at the heatsink as the soldered on 486SX25 that it replaced (the motherboard had a soldered on chip, and a socket for a replacement that disabled the soldered on one) had no heatsink at all.

This was pure serendipity on my part, as I had no idea at that point (early-mid 90's?) that doing such was possible. I just changed a jumper that the manual said changed 25Mhz to 33Mhz, and it magically worked. I'd tried this previously with the stock processor with no luck.
 
I jumped in with the Slot 1 Celeron 300A(300Mhz) I believe it was called. Got her up to a blistering 450Mhz 🙂
 
I overclocked my familys computer 2.8Ghz Pentium 4 to 3.32Ghz and of course the computer was faster!
 
You know us young'ens are gonna get pwned by some of the fossils on this forum (I say that with love) who overclocked the Eniac in their sleep, overclocked the Atanasoff–Berry Computer before breakfast, and overclocked the Antikythera mechanism by mid-afternoon...😀

But my own pathetic history of OC'ing started with a 286 computer, which I set to compute 1M places on SPi and then I climbed into my car and drove as fast as possible to time dilate my perception of how quickly the 286 was chewing through the calc. It was bush-league OC'ing, and had questionable power efficiency once I factored in my gas mileage, but you just can't judge a DIY hobby like this in those terms 😉

LOL, seriously though I did my first OC with a POS cyrix chip (either a 486 or a P-class) as I was worried I'd burn up my processors if I tried to OC before then.

Your own frame of reference never percieves time as changing (distances change for distances you are moving relative to). To the outside observer, you actually underclocked your processor with this endeavor.

Can't remember which I overclocked first as I overclocked them both at about the same time since I had both systems when I learned to overclock.

Socket 754 Athlon 64 3400+ Clawhammer 130nm, got it from the stock 2.2Ghz to 2.35Ghz, wouldn't post any higher.
Socket 754 Sempron 64 3400+ 90nm, stock 2.0Ghz clocked it up to 2.4Ghz.
 
It's been awhile so I can't remember exactly. I think it was the Pentium 75 overclocked to Pentium 90.
 
8088. Hardware mod, had to add a board into the pc that replaced the clock generator. This wasn't in a slot, you had to solder it to the motherboard with about a dozen wires going to various places. Then it gave you a dial to mount next to the big red power switch that let you crank the clock from 4.77Mhz all the way up to a screaming 8Mhz.

Cost about $60 at the time (1985 or so)

Edit: Forgot, I also overclocked a disk drive once. The Commodore 1541 drives were intelligent, had their own CPU and RAM. You could write your own drive controller code and load it into ram and tell the drive to use that instead of what was in ROM. This would have been around '84 I think.

In your haste to try and score a pedantic point or two, I'm pretty sure you totally missed what I was talking about there.

To the outside observer I neither overclocked nor underclocked my processor as the outside observer would have noticed my computer was still in my house, traveling at the same velocity as the observer.

To my frame of reference (I was the one in the car), I experienced time dilation relative to that of the CPU, the CPU somehow managed to do more computations per second (in my frame of reference) than it was rated to accomplish, as I noted when I got back to my house and walked up to the computer.
 
Core 2 Duo, E6400, Conroe. 2.13 stock, reached a little north of 3.7, underwater of course. Late start to overclocking I suppose, but I did start with a bang.

The first thing I tried to overclock: An Athlon 900 (I didn't get very far).

The first thing I successfully overclocked: A Core 2 Quad Q6600, from 2.4GHz to 3GHz.
 
Found back in 2006 a asus p4c800-e deluxe at a swapmeet unused in its original box and bought it for $50.

Pulled a pentium 4 2.4ghz 533fsb chip out of a dell dimension 2400 plopped in it and eventually pulled 3.4ghz using a asus silent knight cooler i believe 😛

Played BF2 alongside a 7800gs with this set up till i went to a e6750 and 8800gts.
 
I don't know if it really counts as an overclock, but one of my first rigs was an AMD 386DX-40, which ran at 40Mhz rather than Intel's 33Mhz.

My first real overclock, was with an AMD 5x86DX-133. I tried running it at 160, and it failed miserably. It erased my MBR, which I had to rebuild manually, using Norton Disk Doctor/DiskEditor.

My first successful overclock, was OCing an Intel Pentium MMX 166, to 200 or 233.

Pentium 2 233 up to "263" by upping the multiplier on an Abit LX6 (that's the speed it reported for whatever reason). After that, Celeron 600 up to 900 on a BE6 via a "slocket" adapter. (maybe the chip was technically called a "600A?" Those Coppermine chips were great...)

Sent from my PI39100 using Board Express
 
Read an article on Tom's hardware guide saying how you could run a Pentium 166 MMX at 200 Mhz by changing one jumper setting. I've never owned a desktop system that wasn't overclocked since then.
