PC gamers have been getting that extra little "oomph" from their game machines through the magic of over clocking, and it now seems as though the PSP will be utilizing a similar technique for its own software.
Chris Kohler from Wired has reported that Sony has given developers the freedom to max out the PSP's potential by allowing overclocking of the PSP so it can run at 333mhz, instead of the current 222mhz.
Although this is great news for owners and fans of the PSP, it will negatively impact the handhelds already slim battery life and have owners using the system in a "not-so-handheld" fashion. Surely an enhanced CPU will greatly benefit the graphics as well as some elements of gameplay, but along with the positive come the negatives and one such negative (other than a poorer battery life) is the amount of heat, or energy, the system will give.
In an overclocked PC setup, usually the PC gamer will compensate for this increased heat by having the system cooled by special modifications so it will run at optimal settings with little strain to the components. If not handled correctly, this may pose a problem to the delicate internal components of the handheld system.
An overheated CPU due to overclocking will lead to the system's motherboard potentially frying, something that Sony will not be too happy to have to deal once consumers start complaining about bricked PSP's. And this is just what the over heating can do to the system itself; just imagine what it will do to a person's hands! Chris Kohler summed it up by saying that “with PSP being eviscerated by the DS, they need to do whatever they can to make it appealing.”
Although this is a positive move and may draw more console gamers, who usually are concerned with top-notch graphics and gameplay, to jump on the PSP's bandwagon, it definitely puts Sony in a position of making significant decisions to thoroughly evaluate this new step forward. Sony may eventually find the need to pre-emptively address the situation as opposed to waiting to react and then having negative attention brought to them from something that was supposed to be a positive.

This sounds like an unnecessary move on sony's part, the psp is graphically superior to the DS already, i think sony should release more simple fun games for it like tetris or some 2D classics to entice newcomers away from the DS. Also release more colours of the console to make it seem more fun
this looks like a bad move to me for sony, the graphiques on psp are already awesome, they should try to remeber what happened to sega's handheld, at the time gamegear had superior graphiques to gameboy, plus you actualy had couloured screen but the gameboy had one thing that gamegear didn't have, LONG battery life. thats why gameboy won.
Please. Why to people believe this nonsense? The PSP is not being overclocked. It can run safely at 333mhz. It was underclocked for the purpose of battery life.

Chris Kohler, even though he has to put a negative slant on it, even words it correctly and these guys at ripten chose to use the term overclock. With the new batteries on the way, even with the COU running at optimal speed the PSP slim is going to have a very decent amount of gaming life left.
staticneuron and nickjd331 are both comlpletely correct on this one. The psp has always been limited to 222mhz to help the battery life. this means that all iof the components inside of the psp will easily be able to handle the estra heat as that is what the system was designed to run at. This means that, yes the batteryl ife will take a hit but it will still be far from unreasonable. And besides if you want more battery life just buy the bigger capacity battery you can now get for the psp as an addon.
And I would like to add that the speed was unlocked in firmware version 3.50 which came out 5-6 months ago. If it was really a big deal I am sure more people would be complaining. I haven't even found a reason to complain and I play my PSP often.
psn id: gingo.. this does seem a bit unnessary but if it doesn't affect is to extremes it may be a good move
As has been mentioned the CPU is not being overclocked at all but rather clocked at the speed that it was originally designed to run at, please get your facts straight before you post more incorrect information in future PSU.
WTF? "eviserated"? hyperbolic much? The PSP is doing fine just because you can't destroy the DS dosent mean it's not doing well, The graphics on the PSP have been heaps better than the DS since it's launch, bumping the CPU up to 333 is going to offer minimal boost in graphics and hardly noticeable battery drain. I get 6 hours out of my PSP slim with the regular battery with the stock battery bumping it to 333 might shave an hour off of that and that's not even counting the newer battery comming wich would offer about an extra 2 - 3 hours. Besides didn't sony already give this go ahead to their own 1st party developers? Because I remember hearing already that 333 was unlocked as long as the Wifi isnt active. So we've already seen games using 333.
The processor is not being overclocked at all. In fact the processor is a 333 Mhz processor that was underclocked to 222 MHz. Homebrew has been running it at 333 Mhz for a couple years now. It doesn't create a problem, it just shortens the battery life a bit.
Old news. Sony unlocked this months ago.
This explains why they are releasing the larger batteries.
Ok, just so everyone knows. This "overclocking" is what is going to make the new God of War game on the PSP look as good as it does. The developers have already said that they appreicate Sony letting them run at 333MHz so that the game looks better. And if you have a slim, or CFW, you already can get good battery life anyway.
They are not "Overclocking" anything. The CPU was underclocked to 233MHZ to allow for better battery life. They are just allowing the CPU to be set back up to what it is made for. It have no effect on the system other than battery life. What we will see however is faster load times and better GFX.
Like people are saying in here, the PSP was built for 333mHz. I have ran my PSP at 333 mHz without any problems and I can say I haven't noticed any increase of heat. But then why would developers build games for 333 when everyones PSP runs at 222 or am I wrong about this? Does PSP slim run at 333 mHz? can anyone confirm this?
As of writing I searched and found at SonyStyle.com that the PSP slim's CPU is in fact running at 333MHz http://www.sonystyle.com/webapp/wcs/stores/servlet/ProductDisplay?productId=8198552921665237696&catalogId=10551&storeId=10151&langId=-1
I think this article is missleading. I think what it means is that SOny is telling developers that they can max out the PSP fully for their games as PSP slim is running at 333MHz and is in many peoples hands.
been running my PSP at 333 for a long time, no fraged mobo
The graphics already blow DS out of the water so they just need to make more games. I love my PSP i think its friggin awesome. If i had more money i would buy a whole lot more PSP games than i do know
