Overclocking

Running P-100, Super55CWA motherboard w/newst BIOS. CPU has info on it showing that with jumper changes the clock speed can be set up to 133. I make the adjustments to the jumper settings and re-boot. It restarts and indicates that its running at P-133 but then after a few lines of the config.sys file......hangs up. I understand that overclocking is dangerous to your health as well as your CPU but I was wondering if there was any other adjustment to the CPU that needs to be made to make the overclock work. And before everyone asks.....No, I just can leave it alone :) ---- heck, I just found the website to upgrade my BIOS from 1.2 to 2.0 and my DMA bench results doubled. Thanks in advance. Andrew

Try reading the info at this site: http://sysdoc.pair.com/ All the info you could ever want is on this page somewhere.

Check what speed your bus is running at. Also I feel you "over" over-clocked it. From P100 to a P133 is too bigger jump. Try setting it to a P120. And once again check your bus speed. I'm pretty sure that a P120 requires a 60 mhz bus speed where as a P133 needs a 66Mhz bus speed. -- Nigel of Lakewood Motorsports Nascar Coruba & Coke Chevy Hamilton New Zealand

Take a look at http://sysdoc.pair.com This site contains _everything_ you need to know about overclocking. One thing you should try is to raise the voltage at which the CPU is working. I overclocked my P166 to P200 two weeks ago without a problem thus far. With higher voltage (didn't try normal voltage though...) Success, Jo =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= When everything else failed, we can still become im- mortal by making an enormous blunder....

The other thing to check is whether your board will do it. For example; many giga-byte boards check and will disable the chip if you overclock. Setting it back to the correct settings then works fine again. Phil.

P100 to 133 isn't a big jump. What you have to do is get your self a big fan - it is call "ice cap" in my country. Overclocking generate lots of heat, if you can get rid-of the heat, then you are ok. check out overclocking page http://sysdoc.pair.com I am running my 166MMX at 207.5Mhz (83 * 2.5) without any problem If you say P100 to 133 is a big jump, what about me?

How do people overclock a processer.If it's a 166mmx like i got than it's running at 166 or maybe a little faster considering it's mmx . I can't figure out how you do it. I have a 166mmx and would love to know how to overclock it..

You have to change the multiplier or external clock speed on the motherboard. Your 166 is running at 2.5 x 66mhz. You could change it to 3 x 66 giving you a P200. With the increased speed comes a lot of added heat, so unless properly cooled you stand a good chance of damaging the system. Some new motherboards support (most unofficially due to pressure from Intel) bus speeds greater than 66mhz (such as 75 and 83). Thus with one of these boards it would be possible to run your 166 at 83x2. This would be quite a bit faster than a stock 166 due to the higher bus speed. -- .

Well said my friend see the DOC HE KNOWS ALL... nuff said!!! Here is a good site with lots of info on overclocking:http://sysdoc.pair.com/ I have an Pentium75 with a Intel overdrive 75-120 overclocked it now runs at 166. > How do people overclock a processer.If it's a 166mmx like i got than it's > running at 166 or maybe a little faster considering it's mmx .

You can either increase the multiplier or the bus speed. If you are running a "OEM" board then it is more than likely running at the factory bus speed of 66mhz. Your board may or may not do this. Try for a 3x multiplier and see if it boots. If so, get a good fan. I wouldn't personally reccommend that you drop bus speed to gain CPU speed. Example: 60 mhz bus x 3 = 180 mhz. Stay with the 66 bus speed. Or up it if you have a m/b that supports it. Like everyone says. Go to the sysdoc page. Toms knows all.. Thought a quick run down might help you.
