I've heard about PowerBook G4 CPU Upgrade heat issues, can you explain?
Yes. The higher speed PowerBook Aluminum Upgraded CPUs do produce additional heat when set to their maximum speeds (1.92 GHz for example). But, you should note that even at the highest speeds, temperatures are well in range of the CPU specifications. Also, they are below industry standards for both Apple and the PC world. For example, the 1.92 GHz Upgrade at maximum speed runs with an external temperature which is 25% cooler than the "business" Acer or Dell laptops currently on the market. It is also 10% cooler than the MacBook Pro.
If you need a cool running PowerBook, then we suggest opting for the lower speed upgrades, such as the 1.75, which actually runs at the same temp, and cooler than the original PowerBook G5 FW800 (12.25 GHz) systems.

Is it safe?
Yes. Daystar has upgrades thousands of PowerBooks. the failure rate is less than 1%.
Shipping is secure. We have tested and used every major carrier and settled on FedEx as the premium standard. They have handled packages for years with the least issues and best service.
The process is tested. We employ some of the best technicians in the world. Our BGA specialists have been contracted to train and teach micro techniques throughout the world, including at Japan's largest manufacturers and distributors. Before releasing an upgrade, we run hundreds of tests, and have extened pre-release programs to verify the process and user feedback.
Your system is safe. Our technicians are prohibited from 'browsing' systems. Your PowerBook is kept in a secure area, and is never viewable by other customes. We install dedicated testing applications and do not modify your OS.

I've heard that the Apple System Profiler may not show correct information. Is this correct?
Yes, on some PowerBooks. Such as the 867/12"...
The upgraded system runs at 1.4 GHz... which can always be verified by opening the testing / CPU utility, XLR8 MAChSpeed Control.
Unlike the CPU speed shown in MAChSpeed Control, the CPU speed shown by Apple System Profiler is simply a number. It does not represent the actual speed of the system (ASP does not check the speed of the CPU at all).
Understanding the reason, requires a little more information though.
All PowerBook G4's have two speeds. You can toggle the settings in Energy Saver under details/options. The two Processor speeds are "Reduced" and "Highest". Apple does this to allow users to extend battery life by running in "Reduced" mode. Apple System Profiler (like TechTool Pro, xBench, etc) does not check and show the true speed of the PowerBook G4. It simply pulls from a pre-configured database which looks at the PowerBook type /configuration, then shows the original speed. Apple does this to hide the fact that the PowerBook G4 actually runs in two different speeds based on the system settings.
MACh Speed Control checks the CPU speed on boot-up and patches Apple System Profiler to show the actual boot speed. Many Apple laptops actually boot in low speed, then switch to high speed when Energy Saver loads. The PowerBook G4 12" 867 is one system that does boot in low speed.
Originally the 867 system runs at:
Reduced: 532 MHz / Highest: 847 MHz.
Upgraded it runs at:
Reduced: 1.2 GHz / Highest: 1.4 GHz.
So, the 1.2 GHz speed that is seen in the Profiler Database is the boot speed of 1.2 GHz. You can see the speed toggle by changing in Energy Saver then opening MAChSpeed Control (it checks the speed each time it is opened). MSC gets this speed by performing a timing test to the CPU/Caches/RAM, like a normal application. It then presents info which is based on the actually responses from the CPU/Caches/RAM.

Can any Apple PowerBook G4 be upgraded?
Yes! We currently have CPU upgrades for all 12", 15" and 17" Aluminum PowerBook G4 systems. These are factory upgrades, and can range for 30% to 90% in speed improvments... depending on your choices.
For our full line of XLR8 Brand PowerBook G4 CPU upgrades for the "aluminum" series , see:
