extreme overclocking

[pa]

what determins how much u can overclock a proc?
if you were able 2 keep a proc at a low temp would u b able 2 overclock it to what ever u want?

[reboot]

Theoretically, you can overclock any processor.
Some will go much higher (in percentage) than others, with the "norm" (if there is such a thing) for AMD's about 25%, Intel about 40%, Cyrix about 10%.
Some AMD's (Duron) will go much higher, but heat is a huge factor.
With peltier coolers, liquid immersion cooling and such, you could get a possible 100% increase.
For example, a Celeron 500 with a 66mhz bus, may actually run, with enough cooling at 133mhz bus. The most I've ever got was a 120mhz bus on a 600 fcpga.
On the PIII, (100mhz bus) it's common to run them at 133mhz bus and I have a 600 running at 150mhz bus.
Stability of motherboard and RAM are huge considerations. The Intel BX chipset probably still rules as the most overclockable chipset (Asus P3B-F for example).
Don't try this on your Compaq, Gateway, or SIS chipset board.

if u could turn an nob on your computer and set it at any temp u wanted could you Theoretically run it at any speed?, 4 get about mobos ,chipsets and ram ect

No, not at any speed.
Even at absolute zero (0 degrees Kelvin, -276 F (i think)) the CPU is only capable of running at a certain speed.
Sure, it's going to be MUCH faster, the colder you can get it (do some research on superconductivity), but the traces on the chip (currently .18 micron in most) can only conduct so much juice at any given voltage, no matter what the temperature, before they simply burn/melt.
More voltage equals more heat. More cooling equals more speed. Somewhere there's an algebraic equation that would work it all out, but there's too many random factors...anyhow, the answer is no.

k THANX just wondering

Yah I was actually discussing superconductivity in relation to computer processors today in my physics class! I think I might buy a really cheap Duron and slowly bring the temperature down till its fully immeresed in liquid nitrogen.....

[pot]

Frey,
being a newbie i sure would be interested in any results of the above
mentioned, shall we say Research, that ya would be prepeard to post.
Regards Pot...

Yah would be interesting man but I dont plan on doing it anytime soon but if someone could give idea's on how to avoid cracking the MOBO then I might mess with my old pentium 133 perhaps.

[pa]

i think the mobo would take alot of -c b 4 it cracks .but where are u going 2 get liquid nitrogen? and the power cables will crack first

[Frey Grimrod]

I have access to chem labs and mom is science teach and step dad teaches science at colledge level so I shouldnt have much trouble getting some even dry ice would be a good start now that I think of it that would be a great solution willonly degrade to some Co2!

but the traces on the chip (currently .18 micron in most) can only conduct so much juice at any given voltage, no matter what the temperature, before they simply burn/melt.

Just a word of info on trying this on a Pentium 133, I don't know what micron process the Pentium 133 is based, but old 486's were based on the 1.0 Micron process, compared to the .18 (and soon .13) process used today. So even if you tried it on a Pentium 133 you probably would not get much out of it before the chip burns/melts. Of course though, if you tried this and something went wrong, it probably would be better to have an older cpu that is wrecked, than a newer more expensive one.

well yah just sumthing Im thinking/joking about and that board upstairs is not planning to be used for much better stuff anytime soon
