how to overclock????!!!!!!

please someone tell me how to overclock my cpu!!!!!

It only works if you can change the CPU-speed by changing the jumpersetting. I've got my p90 running on 100 just by replacing three jumpers and it works great (for almost over a year now) Greetingz Frait

Advice, Don't do it! This is the kind of stuff that I do for a living and the reason that your CPU is a 90 is because it failed tests to be a 100. When you overclock, you are not going to light the processor on fire in most cases, but you will increase your chances of incorrect data processing. This may only happen once in a blue moon but won't you feel better knowing that the number you just got from your computer was correct? -- *********************************************************** * Jonathan A.

Would that be anything like the infamous floating point prob in the early intel chips?

Not really, but I will feel better getting a "P-200" for several hundred dollars less than Intel are asking people to pay at the moment. I had a "P-200" six months before Intel did, and it's still going strong. By the time it's ready to expire, it'll be worth about $20 and I could throw it in the trash anyway. Such is the march of progress. Just the other side of the coin.... Cheers!

I agree wholeheartedly. How did you get to 200? What did it start as? I have a p5-150 juiced to 166 but my mobo doesnt list 200. It has a row of 8 dipswitches and I believe a jumper that I have not located yet. The last 4 dipswitch settings combined with the mystery jumper set the speed. 166 is dips4-8 on and j1n1 4/5. I would really like to go all the way to 200 and am figuring at the most I will replace this CPU in a year so whats to lose. Any ideas?

Just cos your chip say 75/90 etc on it, it does not mean it will fail when you chip it. as far as I am aware Intel speed test a silicon slice of chips untill they all pass a set speed test. Dropping the speed if they get a failure. Sooo your chip may have run OK at a higher speed but lowered due to another chip on the same slice failing the test. my 75 has been running at 100 for 3 months no probs. If this chipping business wreaked chips intel would be smiling as they would be selling loads of replacements. No they have put speed limiters on tjeir new chips to stop overclocking. for a company to do this must be proof that the chipping is working for a large amount of chippers :) rob

[snip overclocking posts] Not sure if this'll help, but if your motherboard is an Intel Endeavor, you can get the most up-to-date documentation on them at www.intel.com. Or maybe your manufacturer has a web page with current documentation on it. The docs I got with my Endeavor were pretty elderly, and didn't document all the switches and jumpers, so I d/led the latest from Intel (along with the lastest BIOS). Voila, how to jumper for 200Mhz. Now, if only I could persuade my P133 to run faster than 133Mhz ... James -- James Bevan NeXTMail & MIME welcome

Hi Rob, Actually the clock-limiting was put in place because the surface of the ceramic was being skimmed off (along with the speed markings), and new markings put in place showing a higher rating. Intel is obviously against overclocking, but the clock-limiters stopped SELLING overclocked chips, not to stop people doing it. I agree with you though, it's a great idea! Cheers!

My motherboard directly lists 200Mhz (66Mhz x 3). _________________________________ __ _____| |_____ __ ________| |__| :| John Wallace | |__| |________ \ :| |::| :| Team WW Racing TSW | |::| | / > :| |::| :|_________________________________| |::| | < / :|__|::|____/ * Sim Racing News * \____|::|__| \ /______:/ \::/ http://sneezy.dcn.ed.ac.uk/simnews/index.htm \::/ \._____\ http://www.math.ohio-state.edu/~harmon/simnews

Just a note that most Pentium motherboards will run at one of three clock speeds, 50MHz, 60MHz or 66MHz. The chips are available in the following speeds: 60MHz (60MHz x 1) 66MHz (66MHz x 1) 75MHz (50MHz x 1.5) 90MHz (60MHz x 1.5) 100MHz (66MHz x 1.5) 120MHz (60MHz x 2) 133MHz (66MHz x 2) 150MHz (60MHz x 2.5) 166MHz (66MHz x 2.5) 200MHz (66MHz x 3) If you have a 100MHz or 133Mhz Pentium, you can't speed it up. It's already running at the maximum clock rate. Most motherboards seem to have two sets of jumpers. One sets the clock rate, and the other lets the motherboard know what the divider is in the chip. To be honest, I don't know if that last one alters any timings, or just changes the speed shown on the startup screen. Some motherboards may possibly support a 75MHz rate. I think I read that Cyrix may come out with a chip that supports that.

Damn! Does that mean that my P133 which has been running at 200Mhz for six months now is lying to me....? :) P-100 and P-133 can be overclocked just as well as any other CPU. A P100 is not as likely to voerclock (with reasons I bored everyone to tears with in Sim Racing News), but a P-133 is an excellent overclocking candidate. Cheers!

I've overclocked a 100Mhz to 120 Mhz without any problems so... Cheers Martin
