Jumpers

[antinous-ody]

Ima noobie at this so i have one question. I have a Presario 1 ghz and i wanna overclock it. The mobo has a jumper on it that says i can change it from 100 133 but when i switch it it wont turn on. Do i need a new processor or what???

What motherboard are you using?

You don't need a new processor, it just means that your processor isn't stable at a 133 fsb. If you want to take advantage of it, replace it, but before you do, try alternate ways to overclock. Try to get into the BIOS. During startup, press either delete, all the F buttons, or Pause+F1. If you can get into it, look around to see if you have fsb settings other than 133.

If there isn't, try using CPUFSB or SoftFSB. If your motherboard is supported, increase the fsb on at a time. Watch your temperatures carefully. Very carefully. Try not to exceed 50 C. You should be able to get the programs from Shadow's ftp

You should also check out the beginner guides on the front page if you already haven't done so. It's a treaure chest of information and hould give you background information on overclocking

If you haven't unlocked the L1 bridges and underclocked the multiplier it is quite likely that your chip (or the temp of your chip) cannot handle 1.33Ghz. (The beginners guide tells how to unlock the chip).

The CPU speed is determined by multiplying the FSB by the multiplier therefore your chip stock is 100Mhz X 10x multiplier = 1Ghz CPU. Try 133Mhz X 7.5x multiplier (also 1 Ghz) then slowly up the multiplier and fsb until your comp is unstable then back down to the last stable speed.

Good CPU cooling is essential and the stock HSF probably will not cut it.

Good luck.

Compaq make their own Mobo and BIOS. I had a K6 Presario and it's overclocking abilities were zero. These machines are not designed with overclocking in mind. You will even be lucky to find a technician who is helpful enough to give you data on the multiplier settings.
Unless compaq have had a serious shake up, and use other manufacturers boards, I would assume that overclocking will be difficult if not impossible. Sorry to be the bearer of bad news.
