    I am new to this site and not experienced when it comes to hardware installation. I just completed installing the Enccore/ST 1.7 GHZ processor upgrade. The computer keeps hanging, prticularly when using safari and then stops responding. The firmware is the correct one (no upgrade was necessary), so I am not sure what is the problem and would appreciate some help.

    I have the G4 AGP Graphics, 30GB with an additional 60 GB internal hard drive (Western Digital 7200 RPM), and the original video card (RAGE 128pro) which I intend to upgrade to the RAEDON 9000 pro once I solve this issue. System software Mac OS 10.3.7

    Cache speed or memory

    Usually hanging is either due to the cache speed being too high or there is main memory that cannot handle the higher speed. Did you run the tune-up application from Sonnet's CD? I'm not familiar with the Sonnet tools, but if you can disable the cache, then see if it still hangs. If it doesn't hang, then the cache speed is the problem. If it does still hang, if the tool allows you to slow the processor speed, slow it down to ~1Ghz and test if it hangs. If it doesn't hang, then probably it's the memory. Then swap out the memory to see if you can test it at full speed without hanging. If it doesn't hang, then the memory that is swapped out is probably the problem.

    Good luck!

    Thank you for the reply. I called sonnet. They suggested I replace the card as it may be defective. I guess I will know for sure once I install the new one.

    Thanks again
