Thought this might be a good place to post this question.
I have been given a spec that claims of a system that runs with a Pentium III processor at 1.8GHz. The fastest that I can find is 1.4G, and my researching skills in terms of overclocking are shoddy at best.
I'll give a membership to the person who gives me the most detailed information regarding running a Pentium III @ 1.8GHz.

Dammit I can't find anything :<

Is this what you're looking for?
From what I gather, you can't reliably overclock your P-III processor to 1.8GhZ because you basically have to have two things going on: 1) You have to have really good cooling to handle the added heat. 2) You have to luck out and have a P-III processor that's capable of being overclocked to that point. The thing is, when determining chip speed, what the CPU manufacturers will do is actually test them to see how fast they can go before they fail. Then they throttle the chip back to a reasonably "safe" setting and sell it at that speed. So when they sell the P-III at its various speeds (1000, 1133, 1200, 1333, or 1400 MHz) it's actually the very same chip, but with varying levels of perfection that allow them to run at those higher speeds. What an overclocker does is start throttling it forward and see what they can get away with. If you happen to have a really good P-III, and adequate cooling, then maybe you can run at 1.8Ghz. The rationale is that Intel stopped testing them at the 1.4GhZ level, there's a possibility the chip can do even better, especially if you operate under unusual conditions (e.g. extreme cooling). Overclocking should be regarded as risky business. The faster your CPU is running, the hotter it gets, and as you can imagine this leads to faster burnout of the core. You might get a 1.8Ghz result, but your CPU might burn out in a week as a result. It's not something you don't want to do unless you can afford to replace the CPU. Possibly the motherboard and memory as well - clocking things up past their normal settings puts a lot of components at risk. It also helps to identify the specific type of Pentium III you're working with here. According to Wikipedia, Intel made, like, 7 of them of varying cores and CPU caches. Knowing the exact make of chip is useful for gauging how likely you are to get away with something. | |
I'm taking the lazy way out. Now, I can't give you much information about what causes what and such because I simply don't know. I do however know they make programs to help you ;). With what I found your CPU should run at
Intel Pentium III 60C - 85C So, here is a program that helps you track your CPU, GPU, and etc. tempeture. Click speedfan 4.40 link on page, you should see it inside the text under the Download table. http://www.almico.com/sfdownload.php | |
You will not get a P3 running stable at 1.8GHz. Is it possible to get it there? Sure. Is it going to run your OS without crashing every few minutes? Nope, you'd be lucky to get to the OS at all. It probably won't pass the BIOS.

Simply increasing the clockspeed / multiplier is not going to increase heat. The heat problem with overclocking stems from increasing core voltage, and when you apply more voltage, you generate more heat. | |

Bzzzzzt, wrong answer! This is obnoxious. Especially when you're wrong. Simply increasing the clockspeed / multiplier is not going to increase heat. The heat problem with overclocking stems from increasing core voltage, and when you apply more voltage, you generate more heat. Yes, jacking up your voltage will increase the heat. However, it's been my experience that my CPU heat does peak higher/faster when the core is clocked higher. Of course, unlike core voltage, it may need to be under load for you to see the increase. Further, some CPUs/Motherboards/Memory/cooling systems will be able to handle this better than others. Sometimes, you can tell that FSB setting is being overridden by internal hard-coded throttling because heat increase does not occur. This thread confirms what I'm saying. Except post #2, which apparently was wrong. Besides, you're jumping to the conclusion that I completely excluded the possibility that the voltage might be increased in the process of getting the CPU to run faster. | |
If increasing the multiplier is increasing your temperatures, you're doing it wrong. Fix your HSF and reapply paste. The increase in temperature from multiplier modifications is so slight, you can't accurately say whether it occurs or not. The ambient temperature is going to affect your core more than the multiplier.

Link me a high profile technical source that's claiming that clocking up your FSB absolutely will not increase your heat, or just accept you're bandying around misinformation with your wrongful belief. I expect the necessary research will educate you otherwise, as more experts would agree with me that clocking up the FSB can increase the temperature than otherwise. At most, you will see people who say that increasing the voltage would increase the temperature moreso, which has no bearing on what I said. I mean, even if I believe everything you just wrote: Fix your HSF and reapply paste. The increase in temperature from multiplier modifications is so slight, you can't accurately say whether it occurs or not. The ambient temperature is going to affect your core more than the multiplier. The advice you gave me was how to deal with the increased heat buildup. Therefore, you just established that you, too, believe increasing FSB would increase the amount of heat that needs to be dealt with. Of course, this is completely irrelevant because your whole "bzzzt wrong!" BS happened because you read what I wrote and assumed, incorrectly, that this was excluded the possibility of voltage increases. | |
