What was your first overclock?

[PhoenixEnigma]

Celeron D 325, I think, based on what I can find on Intel ARK. On a really crappy VIA motherboard, IIRC, the IGP of which I destroyed in the process. Didn't get it very far, either.

 

[Ferzerp]

BH6 and Celeron 300A up to 450mhz...what a rush =)

I too had this pair at one point. I imagine many of us did. The cost savings for the 300A vs the P2 450 was great, and the performance was so close. It was a pretty good indicator of what you can do with faster cache, even if it is of lesser volume. For anyone who doesn't know, the 300A had 128KB of L2 which ran at the processor speed, whereas the P2 had 512KB, but ran at 1/2 processor speed.

The first Celeron had no L2 and was dog slow. The tiny, tiny addition of just 128KB on die cache made all the difference.

I overclocked the gpu in the first voodoo1.
Then for cpu it was the Celeron 300, and then the Celeron 300a
and so on.

Athlon XP 2500+ Barton

E5200 wolfdale

stock 2.5, got it up to 4.0 @ 1.31v. That chip was absolutley golden.

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.

 

[alkemyst]

AMD AM5x86/133MHz chip that I ran at 150MHz in a 50MHz socket which technically wasn't a real overclock.

I did some with 486s and pentiums, but don't remember they were minor improvements.

My first real one was a 300A at 464Mhz and then a PIII850 at 995Mhz (1GHZ! nearly).

... is my second overclock.

The first one was AMD Thunderbird. Between them two, there were a bunch of AMD systems at stock speeds.

 

[sequoia464]

K6-2 ... think it was a 266 - don't remember now what it would do, just remember changing jumpers also to get there. It seemed miraculous at the time.

Probably still have the board and processor.

Lordy. You guys had all the fun. A buddy and I were all over our Apple II's in 1982, soldering and doing weird things like putting in a switch that allowed us to move from DOS 3.3 to 3.2 (to play Zork, of course) and stuff like that. But it never occurred to us to try to speed up the cpu.

Oh, the decades wasted until I decided my i7 860 should do 4GHz.

 

[Piano Man]

I was chicken shit for much of my PC career, so I didn't overclock until I got a C2D 8400. Started with small OCs, but eventually went all out and landed at 4.5GHz rock stable on air. I was hooked after that.

OT: Yeah, those were the days. Back then (CoCo 2), when you wanted to upgrade your RAM, you had to get out the soldering iron!

 

[Smartazz]

AMD Athlon X2 3800+ from 2GHz to 2.4GHz. Pretty fast chip at the time. It actually still works.

Edit: I almost forgot to mention, the CoCo 2 (and the CoCo 3, finally it was officially supported) had a software overclock switch. You could POKE an address, and change the clockgen, from like 0.9Mhz (fast!), to 1.8Mhz (even faster!).

 

[miji]

My first cpu and overclock, IBM 6x86MX PR233

 

[suklee]

I think my first was a Cyrix P150+ that I tried to run at P166+. I had one of those sub-zero heatsinks (don't remember the term), and not sure that I was even successful.

LOL yeah, who doesn't remember the 1GHz "barrier"? So funny how it was treated like it was some kind of actual barrier like the sound barrier, then next thing you know everybody was past it and it was just another meh OC if it only hit 1GHz

 

[thinkwhy]

Intel Pentium E2160. Stock 1.8Ghz ===> 3.0Ghz after 5 min in bios. I wish my current CPU could do a 60% OC like that.

 

[Markfw]

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.

Mine was the genuine IBM PC AT (an 80286) in 1984 I think. I replaced the 6 mhz crystal with an 8.3 mhz one.

 

[Halogen23]

My first OC was an Athlon XP 1800+. I dont even remember where I ended up with it; something like 1.7GHz.

Intel Pentium E2160. Stock 1.8Ghz ===> 3.0Ghz after 5 min in bios. I wish my current CPU could do a 60% OC like that.

The OC I still am most proud of is my ol' E4300, stock also at 1.8GHz, that I clocked to 3.4GHz semi-stable under a Freezer 7 Pro. I backed off until it was stable at 3.3GHz. I remember trying desperately to boot into windows at 3.6GHz so I could get a CPUz screenshot of a %100 overclock, but it never got past the splash screen.

 

[grkM3]

i overclocked my 486 25mhz to 33 by mistake from removing the jumpers and installing one wrong.

After that i went to an overdrive 66 or 75mhz 486 then go into heavy overclocking when the pentiums came out.

Had my p60 running 133mhz with just a jumper lol

 

[drizek]

I don't remember which was first.

I had a 1GHz Coppermine that I did NOT overclock. The computer after that was an AMD athlon xp 2400+ that I did not overclock, and I replaced that with a 2800+ that I overclocked up to 2.08ghz, I think.

But I think before I OCd my Barton I was overclocking my Dell Axim X30. It had a 312MHz X-Scale processor and I was overclocking it up to 450MHz and 500-something.

 

[richierich1212]

I can't remember but it was a thunderbird or duron back then.

 

[byteman99]

There's a lot of old people here.
My first oc was on an Athlon X2 6000+
Took that baby from 3.0ghz to 3.4ghz!

 

[Matt1970]

My first cpu and overclock, IBM 6x86MX PR233

Good lord I remember those. That is actually a rebranded Cyrix. Around the same are my first overclock was a p166MMX I ran at 200. Win95 flew on that.

 

[Phynaz]

Actually IBM made those, they weren't Cyrix chips.
