Are there overclockers among us? And if there are what you have overclocked and how?

I had a GEForce 2, I overclocked that using a software tool called Riva tuner. It worked fine. I don't reccommend overclocking a processor unless you're running a celeron or cheaper processor. Make sure whatever you overclock is very well cooled.

I'm definitely not an overclocker. I did that once for my dad's K6-2 300 => 350 but that was all. Never did that again. And when Gonzo tried to overclock his R300.. muahahaha, should I tell them, gonzy? ;) :evil: Okok don't edit that then.

Well, he tried to o/c his brand new Radeon 9700 Pro and... yum, toasted it :p :D
Ok ok that was not funny but I told and warned you not to do like that Japanese crazy guy, o/c to death to get 20000+ 3Dmarks, and cyrogenically cooling the card.

I have my Celeron 433 running at 540 right now with no ill effects.

i have overclocked my athlon from 1533 to 1540 MHz , and P4 from 1600 to 1608MHz . whoa!

I used to underclock my 1.2ghz TB athlon down to 1ghz for overheating causes...

GenghisK: What kind of cooler did you have with that 1.2GHz TB? Temperatures?

My home computer is 1.6GHz P4 @ 2.15GHz:o.
Computer at work is 2.0GHz P4 @ 2.0-2.4GHz:o.
Note: no extra cooling was required only voltage increase.

I've also had a Duron 600MHz @ 1GHz :) I unlocked the this puppy with conductive lacquer or something similar.

Then there are two Celerons; mine 466 @ 583 and my brothers 466 @ 525, my friends AMD K6 333 @ 450, my brothers Duron 700 @ 933

+ numerous pentiums and celerons that I've gotten my hands on at work:mischief:.

And my horrid Creative GeForce 2 @ GPU 200 - > 240/Memory 333 -> 375:(.

Taisol classic cooler and in summer temperatures went up to 58°C sometimes. So I bought a full copper cooler with a 3000rpm fan. It was much more efficient then and I could get back to 1.2ghz with 54°C at full charge. And normally using vcool I can go down to 30°C.

I had my Duron 750 OCed to 950~1050 for awhile but I find it to run better (less program problems) at 750 so I set it back down to there.

How does one overclock their computer? I don't want to do it (too many risks for me) but I have always been interested in HOW they do it...

GenghisK: What kind of thermal paste you have between the processor and the heatsink? That kind of temperetures are quite normal to TB's.

Step 1. Increase front side bus by small amount ie. from 100MHz to 103MHz.

Step 2. Boot computer. If computer starts normally return to step 1. If computer doesn't boot goto step 3.

Step 3. Increase CPU voltage and go back to step 1. If Voltage is at maximum or CPU overheats lower fsb until all works normally again.

Step 4. Make sure the computer runs stable with new clockspeed. If it doesn't lower the fsb again and run stability tests.

It's not always this simple. In example you have to watch that PCI clock does not go too much above 33.3MHz or you might fry your harddrive or PCI cards. In some cases you need to increase memory voltages te get them to work with higher clock speeds.

My Duron 600 needed quite a bit overvoltage before it reached 1GHz. Maximum voltage ABIT KT7 gave was 1.85V so I had my friend make a voltage modification on the motherboard to get maximum of 2.05V. Still i could run it with aluminium heatsink and some extra case cooling.

New P4's (Norhwood core) are quite good for overclocking and I bought my 1.6 P4 with that in mind.

Yeah I know TB's temperature are about that range. But I was surprised that XP are running higher frequencies but do less heat. Only 24°C-45°C for an Athlon XP 1700+ on a Shuttle SK41G Mini pc with only a heat pipe, no fan...

And I don't use paste, there's already a thin paste layer on the base of the copper fan (the part that will be put on the processor core).

so childish for nothing. o/c to have faster running internet explorer

Well sometimes it's useful you know. for instance, my brain. Normally it runs at 1Mhz with my mononeuronal brain system. But in need times I can easily overclock it up to 2Mhz, to solve some network of firewall problems at office... And without overheating of course.. Aspirin helps.

sport cars analogy, make it run fast 1/4 mile, and then what ?
it is all good

I don't close the computer case (everything in computer exposed), so does that help keep things cool for overclocking? How do you get some sophisticated cooling systems?

Civddict:
My primary good reason for overclocking. It saves me money :)

Sim_One:
Sometimes keeping the case open makes thing worse. Some cases have good air circulation and if you keep the case open it may mess it up.

If someone is intrested, this might be helpful...

Under some circumstances this may actaully hurt the cooling. It all depends on how the inners of your case is organized. The absolute best way, not counting the exotic and expensive methods like liquid cooling, is to tie all of your wires inside the case to the case's side. Then have a fan sucking air in through the front and another pushing it out through the back. Then close the case.

The steady flow of air through the case allows for what is called forced convection cooling (this is why when you blow on your hand it feels cool). If your case is open, the air around your processor just sticks around and as it gets hot, it does not cool the computer as well.
