Hi there, Is it possible to overclock a psp so it can run at 333mhz? if so how can would i do it?
cheers,
 
depending what firmware you are on u can press the select button which brings up the menu or go into recovery mode holding the right shoulder button whilst turning on psp
 
if you psp has hacked fw on it
then hold the right shoulder button while turning it on
the option to change the clock speed is there
 
Any idea's what the clock speed should be set as when I'm playing a n64 rom?
cheers

daft question but if you upped the speed what would happen??
 
This is quite poinient. SOny have upped the mhz for all games to 333, as of 3.50, not sure if this is for PS1 games, or all, but I definately know that Sony have introduced something in the firmware to be able for all games to run at 333.
 
the battery drains faster :)

Sony removed the cpu limit in a previous firmware for the original PSP, I think this was to cater for PSP god of war

Yeah, and this is the article I was talking about.

"A few months ago, Sony finally unlocked the PSP's full processing capabilities. It was always locked to 222MHz, but since firmware 3.50, developers had access to 50 percent more megahertz of power. Ready at Dawn, developers of God of War: Chains of Olympus, found themselves relieved by the removal of the processor restriction. They were already hard at work on the game, optimizing for the lower clock speed -- but when they had access to the full power of the PSP, things got really interesting.

This video demonstrates the differences between a months-old version of the game, running at 222MHz and a newer build, running at 333. The differences are subtle at first. The game was never a graphical slouch, and would've been beautiful even with a restricted clock speed. However, you'll notice better lighting, more particles, and a few minor differences in the newer builds. Every minute difference adds up to create an experience that will be unparalleled on PSP for quite some time."
