umm Square Enix = graphical god

do i need to say more 

I am kind of skeptical. I would think this would affect the CPU temperature. It would be bad to have the PSP melt in my hands.

If i recall, I thought the gta series went at 333mhz on the psp, might be wrong on that, but thought that was the case of the battery draining faster when playing that game.

This is really odd to me - and is the first time something like this has happened on any console/games device?

Is it only set via the BIOS? Can games control this? Will games that require it, automatically upgrade the BIOS?

What happens when a 333Mhz game tries to run on a 267Mhz PSP?

It could be possible that the new PSP will always run at 333Mhz - but that could risk compatibility issues with older PSP devices...

What about old games? Will the PSP detect that they run at 267Mhz, and switch back to a lower multiplier? This doesn't seem to me to be something that can be configured on the fly (BIOS change, and reset of device).

Hmmm....

To be precise only Ratchet and Clank works with 266 MHz.

EDIT:

@ shams

No worry about combatibility with previous titles. Games works with different clock ratio right now. If R&C:SM can work with higher clock than everything else it's really not a problem.

 all PSPs can run at 333MHz, they just have the clock speed downscaled to boost battery life. This is just a firmware update that will unlock the clock prescaler and allow it to run at 333MHz for commericial games. The prescaler can be changed on the fly (my Pentium M laptop will dynamically change between 800MHz and 2GHz) but I doubt it will be necessary.

The new games that require it will simply require this version of the firmware, like games have always done on the PSP 

 PSP CPU was designed to work with 333 MHz - Sony decided to downgrade it because of battery life.

As long as games can adjust the clock ratio on the fly (or startup), and do set the required clock rate - its all good.

Even though its not intuitive, running at a higher clock rate than a piece of software expects can actually cause syncing and crash issues.

...

So the firmware/BIOS update comes on the UMD? Surely it couldn't get to the point where you purchase a UMD game, and it doesn't run?

(no big deal really...).

While its impressive to see a console that can increase its capabilities over time there is just something about having to download firmware to make your console do what arguably should be expected out of the box that makes me uneasy. I guess its just being dependent on an external source to utilize your purchased hardware at its ideal capacity that bugs me, but then again I've always liked consoles because I saw them as being finite and reliable, self contained. Anyone else share this stance or am I the odd one out here?

Okay, I would figure that since they are releasing the upgrade themselves. I've just had bad experiences with overclocking.
