Title: Overclocking psp past 333mhz
Post by: Peewee2000 on December 02, 2009, 05:37:58 PM
I know most people say its impossible but i remember a youtube video with someone that said they got ahold of some gba emulator source code (i have a gbc emulators source code) and was able to overclock it by changing someting in that. Also i know that theres some crystals on the psp near the processor but i dont know if any of them control the clock frequency, i wouldnt mind replacing them to change it.

what would you be intending to do with such an overclocked psp?

improve hombrew like a gba or n64 emulator or other homebrew that might need a more powerful processor
Also for bragging rights that my psp 1000 is better than a psp go

I'm no expert in processor so my advice is probably wrong but I'm going to say not possible by just changing the crystal but again I'm no expert so I could be wrong.

anything can be overclocked to an extent but would you like the tradeoffs ? System instability , decreased battery life , over heating coz after all space is cramped with no external cooling.... 333mhz is the stock speed of the mips processor... Anything beyond that is going to exponentially harm it and will bring down its life...

well if i did do this i would put a nice fan inplace of the umd drive and get one of those 3600 mah batteries

PSP - overclocking (366/400/466) Mhz (http://www.youtube.com/watch?v=EUnuWrb5GqU#normal)
Note what it says at the end...

hm you can try to cool the processor, maybe this will help a bit..but i dont think this would be noticeable
though it would be very interesting to see whether emulators can profit from that or not.

i didnt realize that the tool was out now, id seen that video before but i never noticed that thx for showing me that, but where can i download the tool?

If u wer to over clock it. Would your games, vids an sound play in a fast forward state? Were is this cristals? Is it on psp 2000 aswel an wot does it look lyk?

Lol. Fyp don't try it. That's not what you even do most likely.

A fan won't help this at all, zephyrus. Not a bit.

yeah i just meant cooling in theory..what about watercooling?..lol..again i think this would only be posisble in theory..but who knows? :yess:
ah and what i meant with processors would profit from that is overclocking, not cooling bud

You're not going to be able to effectively cool it, though. I know what you meant lol

exactly as kicks said... you wont be able to effectively cool it.

@fyp : No , overclocking doesnt mean that everything runs at a faster speed lol ! it just means that you have more performance headroom.

@fyp and @zephyrus : Overclocking will have absolutely no positive effects in OFW related services. Games will run normally like they have and neither will videos run faster / of higher bitrate etc because there are software limits set inside the firmware which will prevent the device from displaying. ( In addition , its not only the processor which is doing the work , DSP chips etc are also responsible in playback of stuff)

The only scenario where it MIGHT be helpful is in running extremely processor intensive emulators like the N64 emulator but even there , the devs are using a dynarec i believe which should already be squeezing out maximum potential from the processor.

So overclocking will only bring about system INSTABILITY.

accepted :victory:
but though i would try it if i had a working psp..but not often
