I did some open firmware commands to see if I could change the speed, and it appears to have worked, but is system profiler just showing an incorrect speed?

Rabidz,

Considering the fact of the locked down architecture that the G5 is, please present us with a screen shot of System Profiler. The About This Mac window is easily spoofed.

Even the system profiler can be easily modified. Open up Geekbench - it shows what speeds your CPU's are running at.

Why would anyone do that?

(but since you brought it up, how's this for A Mac G5 porn fantasy?) :D

How'd you get it reporting that?

Disregarding whether or not it's actually running at 3GHz, or it thinks it is but isn't, or isn't but is reporting it anyway.

You been playing with those PLLs you found?

I wouldn't mind bumping my G5 up to 2.4GHz ;)
 
He was messing the OpenFirmware. Adjusting any G5 PLLs will burn up the CPU upon power or not start at all.
 
So... what exactly did you do? Did you really run some open firmware commands or did you do a quick hack to change the value?

I just spoofed the speed, but I thought it might work, as it might boost the cache, but it benched the same.

Maybe I will try, well, maybe not, I think I fried my powerbook...

Spoofed the speed? How? You can't just "spoof" the speed and expect it will run faster.

It is like adding an extra '0' with a permanent marker to a $10 bill and expect people to believe it is a $100 bill.

If the cache ratio is other than 1:1 then I thought it might boost cache speed.

Who are you trying to impress?

It is not possible. Back on the topic, I'm going to answer:

No, your G5 is not and never will run at 3Ghz. And no, you CAN'T install a Power7 chip to get it running at 3Ghz

'Spoofing' is not overclocking.

You need to ask?

Yes. May be he found some hidden feature that we don't know of :rolleyes:
