I did a search and didn't notice any results so I figured what the hell, might as well ask.
Has anyone attempted to overclock the cpu and/or gpu?
It'd be interesting since all code is running at CPL0 anyways, any performance gain, however slight, could help those games that have 'sluggish' moments.

No.

By no, do you mean, no you haven't personally done it? Or haven't heard of it? Maybe you just believe it's pointless.
Your response was slightly vague to come to any conclusion.

I mean no jumpers to overclock. There is only that chip thing that sets the speed. If you could figure out a way to take out the processor and the clock chip and stick in new ones you are my hero. But until then there is no hope.

don't know where this is controlled but it should be possible.never tried it and never heard of it.its just needless.every game runs fine.overclocking would be extremely dangerous.the xbox case is that damn small that any extra heat could cause a overheated xbox.the life of the hardware would be shortened and that for only some hundred of seconds where the xbox is loading a video or similar.

It still seems like it would be something someone should have looked in to. Add proper cooling and the heat issue wouldn't matter
I'm just suprised that isn't the case so far.
And OCing wouldn't really speed up loading times per se as much as speeding up points in games where they are pushing the limits of the console and the z-buffer/stencil compression isn't working very good

And cpu overclocking would enable to have programs running that interact with the game without worrying about the game slowing down.

It would be cool if you can mod that clock setting crystal chip. But not only is this impossible using non-commercial grade technology and without redesigning that chip, it is too expensive.

We would still be in the stone age if we listened to all the NO-sayers.

This guy has news posted on overclocking, but has yet to follow up with the "how-to" guide that he spoke of.

I am sure someone will correct me if I am wrong here.

The Xbox does not operate like PC.
Its a game console.

The xbox is a Mode 1, Ring 1 computer this means that it can only run one
application at a time and that game/application speed is directly tied to the CPU speed.

What this means is, like with any other game console,
if you speed up the processor you will speed up the game.
Overcock an Atari or a Sega Genesis and you dont just get faster processing but the game time speeds up as well.

Overclocking the xGPU might do the trick tho... I dunno... I am all for it if its possible.
Cooling is an issue easily over come.

No, the xbox uses a standard intel chip.
Xbox games run as CPL0 (Ring-0) for speed reasons. If the game was to run at CPL3, everytime a kernel function was called, a context switch would be required. A context switch takes around 1000 cycles. Since there is only one process running, it doesn't make sense to run at CPL3 anyways.

knowledgeiv - Thanks for the url thats the kind of thing I was looking for.

So, Mage...
I was wrong in my statement Ring1...
it is Ring0
(shit I dont know I lam learning and having fun on this one)
but does that mean the xbox is overclockable without speeding up the game?

good question!!

thats right i dont see the point to overclocking it adn i guess there aint much peple seeing that couse u couldnt find any pages about that

i'v looked everywhere for info on this and you guys gave me the most info.. you guys really know your shit

devery game runs fine.

I fully disagree.
Games like UT Championship run like total ass. There will few frames in as small level where everythign will be very smooth but as soon as you drift back into looking down the hallways the game slows down and becomes noticably jittery. This is true for every systems I have played the game on. Also, games like 007 all but come to a hult with 3 or more players and a few bots in a huge room.

Any bit of speeding it up would help.
