I saw the CPU CLOCK options under the firmware's options menu, and I saw a difference at the XMB speed while lowering its CPU CLOCK, but the game speed was the same even if I got the CPU CLOCK GAME to the lowest possible.

Why is the CPU CLOCK option not working with games?

I tried it with God Of War: Chains of Olympus, also because I noticed some framerate slowdowns (i'm using an ISO file so it's not about decompressing) once in a while which I don't think should be present (even though they're not too strong), and after seeing that the CPU CLOCK GAME option isn't effecting the gameplay at all, I suggest it may not even giving the game the full CPU power it needs?

And another small question related to this topic; why does the CPU speeds at the option menu are written this way: "100/50", "222/111", "333/166" etc.
Why does any of the CPU speeds is written as it's beeing divided by its half?

Thanks in advance.

I Will try to answer your Q's okie....cos this is as far that I know.


CPU CLOCK XMB What is this & when / why would you select the different options?
DEFAULT
20/10
75/37
100/50
133/66
222/111
266/133
300/150
333/166

Lower cpu speed increses battery life. higher cpu speed makes some brew run better on wifi. ie using irshell for a remote... will drain a battery in about 3 hrs. on normal. on low it gets about 8

Pretty much when the game requires u to change it . i never do change the game speed.

I know what they are (and the XMP CPU refers to the CPU speed when viewing the PSP's XMB interface).

I meant that for some reason the GAME CPU speed doesn't make any difference.

And by the way, what will the default setting do?

Hi, just put it all in the maximum, the baterry power will be less, but the games are quicker, on loading and playing too.
That´s why they put that option...
