Overclocking


Anyone out there with some good step by step info on how to overclock?

I have found lots-O-stuff on the big bad web but most assumes a higher level of knowledge than I have.

Thanks
Newb

well.. overclocking isn't recommended as something to futz around with if you don't know what you're doing -- the risk you run if frying you CPU from overheating.

This is done from your system BIOS

Ah exactly! One must FUTZ if one is to become knowlegable.

This machine is expendable so FUTZ away my friend FUTZ away!

"well... i guess... just know the risk you run..."

Ok here is the logic...

I am killing three birds with one stone

The dear wife sees no logic in buying a new computer when we have two that work. If I kill this one then... We only have one computer and I now have a reason to buy another.

If it works and the Overclock holds out for a week, a month, a year, then I have a faster machine for the time that it holds out.

In the process I learn how to overclock.


I have it all thought out so don't worry I have a plan.

Well then, to answer you question you need to take a look at your BIOS. The basic notion behind overclocking is to set you computer up to run you CPU / RAM / Busses faster than they were intended. Sometimes this works and sometimes it doesn't!

To do this, there are several options. One is to increase the bus clock speed. A second is to increase the clock multiplier. The bus speed will over clock your entire system including RAM and PCI I believe. The multiplier is what number that is multiplied by the bus clock to get your CPU speed. (i.e. a 400MHz FSB with multiplier of 6 gives a 2.4GHz CPU)

To change these some of the newer MOBOs make it easy by offering jumperless configuration. Basically you can reboot, go in to you BIOS and change the settings to something you think should work and reboot. (I would start with small changes to begin with!) My new ASUS board will actually let me set that I want it overclocked by 5, 10, 15, ... % and set everything automatically. (Cheating, but nice)

If you have an older MOBO you may have to dig into the computer and change physical jumpers to select the different FSB and Multipliers. You will need to dig up a manual for your MOBO to do this.

Another thing to keep in mind is that as a CPU increases its speed, it also increases the amount of power it needs. Because of this and the regulators on the boards, you are also limited by the available voltages. Again, some boards give you jumpers or BIOS settings to increase the core voltage from say 1.42V to 1.46V so faster speeds can be seen producing larger voltage drops. A warning here though, this is very very dangerous for the boards and is a very easy way to make a nice PC go up in smoke. So far, I have never tried overlocking a board to the point that I need to change the voltages, even though my BIOS supports it.

Typically if you do bump things up too high, your CPU will overheat and everything will lock up. This may be at boot up, 30mins later, or only when you are compiling something or working with video. It just depends. This doesn't mean it won't damage the CPU, just that if you don't push it, one or two lockups "usually" doesn't hurt.

Well, hope this helped. I agree that trial and error is a great learning tool. Just understand the risk and don't try to push it. If you have an old P3 500MHz or something similar, don't try for 800MHz or 1GHz out of it. You might be able if you liquid cooled the internals but other than that be happy with 550MHz or something around there.

Oh, also know that it depends on the CPU. I have an older P2 400MHz that rolls over dead when I try to push it to 425MHz. My Athlon-XP 2600+ (1.9GHz) can easily does a core clock of 2.2MHz with out a care in the world. All CPUs are not created equal.

Happy OCing,

PhilD

what great logic:
the wife won't let me buy i new computer, so i'll actively try to kill the one i have!

that's awesome. no argument here!

What hardware are you running, i'll let you know what you can expect.

Also overclocking is not even close to being as dangerous as many people make it out to be. With the right hardware, one could max out all his voltage settings and not hurt a thing, a variance in voltage from 1.65 (stock barton 2500+ voltage) to 1.85 is rather safe (given your not running hot, meaning your running efficient cooling) On this particular arcitecture (barton core) a 2.0 voltage is where you are playing with fire (sort of, if you have the cooling your still fine, although you will now drastically lower the life expectency of your processor, but hey youve lowered it by say 50 percent, thats still about 7-9 years)

If you want to learn about overclocking and how you can save a good amount of money doing so, or atleast get more out of your hardware (and in AMD's case you get TONS more) checkout ocforums.com This is probably the best overclocking forum on the net, not including extremoverclockers.net or .com i dont remember. Either way the ocforums one is better managed and moderated, enjoy and good luck.

P.S. You can follow what Phil said, there you can get the basics, then you can become more of a pragmatic and go see what works and what doesnt. Just remember cooling is the most vital thing, well almost, the electricity accually is but right next to that is your electricity, its the food, the better the hardware is feed the better it will perform.

P.S.S. The first thing that people usually burn (and this is really easy todo) is their ram, so you might want to hold off on that one first, the ram sticks that people usually get have cheap pcb's (the plastic thingy with all the chips on them) and badly sodered chips, that and usually dont have any cooling on them (a heatspreading would do wonders)
