What was your first overclock?

Just started OC'ing with the 2500k I have right now. In fact, I turned it back down to stock clocks, because I really don't need the extra Hertz; I'll overclock it in a few years when it starts getting long in the tooth (and I have a GPU that can keep up with it).
 
I've never had the pleasure, as I've been using laptops the last 2 years pretty much, and before that a Pentium D with stock cooler, which ran real warm at stock 3.4GHz and I can't imagine would have had much headroom anyway. I didn't really start to get into computers and technology until I had that PC and started playing games. A BF2 forum was my gateway into technology, oddly enough.

My first overclock will probably be a 2500K or Ivy Bridge equivalent, if I can hold off on a desktop until Ivy Bridge.

Cyrix was fabless and formed by guys who were ex-TI'ers, they had TI fab their chips originally, then TI got greedy and stole their plans for themselves (surprise surprise, ala AMD style), so Cyrix took their chip designs to IBM to have IBM be their foundry, IBM accepted the mission but on one condition - they got to rebrand a percentage of the Cyrix-designed chips that IBM produced as being IBM chips.

Cyrix accepted the deal because it screwed them over less than TI was screwing them over (which was less than AMD was screwing over Intel, we may have stolen their plans for ourselves but we were generous enough to offer to keep producing chips for Cyrix in the meantime).

I was at TI when the less-than-ethical stuff was going on, but no less unethical than was going on at AMD at the time. It was, uh, interesting times. Not our proudest moment. 🙁

To my knowledge, IBM never designed their own x86 CPU at any stage in the game. But they foundered a few of them.

edit: wiki link kinda hints to some of it.

Thanks, IDC.

Not to derail this thread but...
In June 2006, AMD unveiled the world's lowest-power x86-compatible processor that consumes only 0.9 watts of power. This processor is based on the Geode core, demonstrating that Cyrix's architectural ingenuity still survives.

ARM KILLAH!
 
I believe my first overclock was on a cyrix chip. Can't remember how far I pushed it very long time ago maybe only 20-25mhz over stock. Then at the Pentium 2 Era I P2 350 @ 400. And been doing it ever since the early 90's.
 
My first that I really remember was the old AMD Duron, it was clocked at 600mhz and required me to use a conductive pen to unlock the multipliers and I ran it at 1000mhz. Though I later reduced that down to 900mhz.

That's the first one I remember and have been overclocking ever since.
 
I remember my first time, it was a 286 wearing a basic beige chassis, I roughly grabbed the top panel, pulling sharply and lifting it up. Underneath all the delicate parts were revealed to me. It wasn't my first time looking inside, but this time I was going further than before.

I got out my tool and gently unscrewed the mainboard, tossing aside the floppy and HDD cables. Once I had it in my hands, I searched the top, my young hands fumbling for the small silver nub I had only seen in magazine pictures before. Finding it, I carefully eased it out of the socket, pulling the new clock crystal from its box, I squeezed it back in, pushing every pin down firmly. Having finished I slid the mainboard back into the chassis, and pulled back on the cover.

Pushing the power button, I smiled as the monitor came to life, a quick check revealing that I had succeeded in replacing the clock crystal and overclocked the machine.
 
in the 90's I had a Pentium 120 and was able to overclock it to 133 or something like that. I also jumped on the 300a. My brother had the Abit BH6 and i had the aopen AX6BC motherboard. Both ran comfortably at 450, and could be bumped up to 504 on the BH6 with a little extra voltage. I think my next was the celeron 566 @ 850. I miss those days - now I just have a dell and don't even know what speed the processor is.
 
Athlon XP 1700+ Tbred running at XP 3200+ speeds. (Don't remember the actual speed though.)
 
Pentium III coppermine, 700 to 784. I tried higher but I didn't know then what I know now... 😉

Does it count if I go "back in time" and overclock my TI-35 plus calculator that was built in ~ 1985? It's on my desk right now...
 
Pentium 3 Coppermine 700Mhz to 933Mhz. Also the first system I owned to have 1GB or more of system RAM installed.

From Wikipedia:

As part of the manufacturing agreement between the two companies, IBM received the right to build and sell Cyrix-designed CPUs under the IBM name. While some in the industry speculated this would lead to IBM using 6x86 CPUs extensively in its product line and improve Cyrix's reputation, IBM continued to mostly use Intel CPUs, and to a lesser extent, AMD CPUs, in the majority of its products and only used the Cyrix designs in a few budget models, mostly sold outside of the United States. IBM instead sold its 6x86 chips on the open market, competing directly against Cyrix and sometimes undercutting Cyrix's prices.

600MHz slot A athlon
I remember the FIC motherboard didn't allow much overclocking so I had to use a windows program to overclock the off-die cache. This wasn't too fun, but got me interested.

After that I went socket A and had the best times ever.
my modified A7V KT133 motherboard showed me some great times with nearly a dozen athlons

RIP socket A, thunderbird, thoroughbred, etc.

That would be 2.2 Ghz (Ran a Barton 2500+ at 2.2 for quite a few years.). 2.2 on a 1700+? impressive.

1st o/c was an HP Vectra Pentium 75 running @ 90 (jumper). Win95 seemed faster...or maybe it was the placebo effect... 😎
 
tried to overclock a PIII 450 without success but some time later overclocked a AMD Duron 1.0 to 1.3 ghz if i remember correctly. The pencil...
 
I think I tried on a P3 500MHz...can't remember if I was successful.

First one I remember is P4 1.4ghz to 1.7ghz...yay for RDRAM. 😀
 
My first overclock was a K6-233, that I ran at 250MHz. Even that minor overclock lost stability after a couple years, and I had to run it at ~210MHz to be stable again.

I would take that result with a grain of salt, since you don't believe in stability testing.

My friend's E5200 would do 4.0 too, without stability testing. But with stringent testing, it was only good for 3.75.

Prove it.

I ran P95 on it and it was fine, so how exactly dont i beleive in stability testing?
