do any of you know of any faqs or knowledge of how to overclock a PS2?
i dont mean for its graphics to look better just that the game go faster.

not that i know of. besides it's unnecessary.

Timing is very sensitive on a ps2 due its multiple processors, so overclocking may just make games crash.

...that sucks! But with the understanding of the risks involved, are there actually any documents that could be used to help speed up the PS2 a little? For experimental purposes?

r2rX ...?

I don't think any such documents exist. If you were to overclock a ps2, you would either need to modify the bios, change the hardware, or both. The best way to speed up a ps2 would be to increase its amount of vram, but this wouldn't due much because games are programmed to only use 4 mB anyway.

multiple processor? how many processor did PS2 use actually?

The PS2 uses embedded VRAM so this would be extremely difficult at best . If you can overclock a Genesis and a Dreamcast, why not a PS2?

I'm not saying its impossible, but it would require a good amount of knowledge about the ps2 hardware. You can't just go into the bios like you can with a pc and change voltage levels. You would probably need to create some kind of custom bypass circuit to change voltage levels and clock rates and then solder the circuit into the ps2 mainboard somehow.

But I'm kind of talking out of my a$$. It may be the case that the clock rates and voltage levels of the processors in the ps2 are controlled by the bios, but I doubt that. This is just my educated guess.

The emotion engine alone has 3 independent processors: a MIPS based floating-point processor and two floating-point vector processors. The ps2 also contains the I/O processor from the ps1 to ensure backwards compatibility. Aside from those, there may be a few minor processors for things like sound/music.
