Powerbook G4 Overclocking... currently at 1.58ghz

Hey, new to these forums but I am not a nooB. Before I start, I'd like to mention I'm CET certified and I worked as an apple tech in high school. (Just saying to avoid the flames)

Here is the deal. I bought my 1.5 Ghz 15" Powerbook used last august. It's a a1095 model (bluetooth 1.1), and upon buying it I immediately upgraded the hard drive (to a 5400rpm 100gb toshiba with 16mb of cache), the ram (I bought one 512 module) and bought 10.4 and installed it on the new hard drive. Sometime after, I noticed "About this Mac" and Apple system profiler both reported my machine as 1.58 ghz. I tried to research why this would be but I have found no answers. Now its time to upgrade the computer again, I would like to research this as much as possible.

I found one other thread about this on another web site, but it came up dead. I'm including the screen shots for proof. The only other speed enhancement I have made has been overclocking the Mobility Radeon 9700 by 40%. I'm including the screen shot of that as well.

By my calculations, I would have to be running at a bus multipler of 9.5. If this is normal, please let me know. I would have guessed most "normal" 1.5 ghz G4's would be running 9x (167 x 9 - 1506 ish)

Lastly, I'm completely disassembling the computer soon to replace case parts so if there is any interest I can take pics of the motherboard (if it would help to solve the mystery). Oh, and since sept 2006, with the 40% gpu overclock as well, the machine operates rock solidly. Here's the eye candy:

First off, welcome to MR.

There seem to be a couple of web reports of people receiving powerbooks that claim / appear to be 1.58 from Apple.

There's one halfway down on this page:

Why would I need to get rid of the serial number? That was the information I found before... but it really doesnt say much.

I dug up some old xBench scores I was running at the time:





Kinda makes it more puzzling though since this shows it happened after I upgraded everything. Maybe it was after I overclocked the GPU..

off topic, and a completely n00b question, but what harm can come of showing the serial number? is it prohibited by apple or something?

Edit: lol greenlightracer beat me to it.

People can probably use your serial number to answer questions to potential buyers on eBay.

That is the only reason I can think of.

It's also used for warranty purposes by Apple. When my friend's PB battery died prematurely he called them up and got a new one over the phone. The only thing they asked was the serial number. This was some years ago.
