    Power Mac G4 (Mirrored Drive Doors): Does Not Wake From Sleep With Radeon 9000 Pro Graphics Card

    A Power Mac G4 (Mirrored Drive Doors) computer with an ATI Radeon 9000 Pro graphics card installed may have difficulty waking from sleep.

    Symptom

    When you press a key on the keyboard, or move the mouse to wake the computer, it may briefly wake up, but then unexpectedly goes back into sleep.

    This issue occurs when one of the following is connected to the display card's DVI port:

    * a monitor with a DVI-style connector
    * a VGA monitor using a DVI to VGA adapter
    * a DVI to VGA adapter that does not have a monitor connected to it

    Products affected

    * Power Mac G4 (Mirrored Drive Doors) with ATI Radeon 9000 Pro graphics card
    * Mac OS X 10.2

    KB #61697

    A Power Mac G4 (Mirrored Drive Doors), Power Mac G4 (FW 800) or Power Mac G5 computer may restart after the computer has been shut down when it is connected to certain third-party VGA and DVI displays using the DVI connector on the computer.

    Symptom

    The computer restarts after it is shut down. This occurs when certain third-party VGA and DVI displays are connected to the computer's digital video interface (DVI) port.

    Products affected

    * Power Mac G4 (Mirrored Drive Doors)
    * Power Mac G4 (FW 800)
    * Power Mac G5
    * Some third-party DVI displays
    * Some third-party VGA displays (with DVI to VGA adapter)
    * Apple graphics cards with both an ADC and DVI connector

    Lightbulb MDD Memory Upgrade

    Power Mac G4 MDD 867DP, you can click on this article:
    http://docs.info.apple.com/article.html?artnum=75382
    In it Apple says that PC2700 and PC2100 will work together on a 133MHz bus as if they are both PC2100 [backwards compatible].

    For your reassurance, on page 23 of Apple's "Developer Note" for "PowerMac G4" dated March 14, 2003 [this note is for the FW800, I don't remember how I downloaded it]: "For the 1 GHz PowerMac G4 computer, the main memory bus connects the main memory to the U2 IC via a 133 MHz, 64-bit data bus. For the 1.25 GHz or 1.42 GHz configurations, the main memory bus connects the main memory to the U2 IC via a 167 MHz, 64-bit data bus. For the 1 GHz computer, the minimum speed DDR is 2x133 MHz, which is DDR 266 (PC2100). For the 1.25 GHz and 1.42 GHz computers, the minimum speed DDR is 2x167 MHz, which is DDR 333 (PC2700)."

    I draw this to your attention for Apple's references to "minimum speed DDR." When you combine that language with the first article's info that says PC2100 RAM alone will not start up a Mac with a PC2700 minimum requirement, and will not even show up when mixed with PC2700 RAM where that is the minimum required - you can see that Apple is talking about backward compatibility.

    You can then click through the apple tab up above, then "Hardware" underneath, then click on "Mac mini" and "Tech Specs" to see that Apple regards their memory spec for the mini to be "PC2700 (333MHz) DDR SDRAM." If you are familiar with the FACT that Apple is delivering most Mac minis with memory that is PC3200 (400MHz) DDR SDRAM, and read what one of their largest memory suppliers Micron [Crucial is 100% owned subsidiary] says:
    http://www.crucial.com/kb/answer.asp?qid=4032

    then you understand that Apple specs are minimums, and that, when it is to their cost advantage, Apple is happy to supply their customers with products that are far above spec and are of more recent and improved design. More PC3200 RAM is now sold than either PC2700 or PC2100, therefore the higher volume product has become the lower cost, and CAN be sold at a lower price (not that everyone will publicly quote a lower price).

    You can also go here and read Micron's 2003 press release about their introduction of DDR400 memory (PC3200) and that new product's support for DDR333 (PC2700):
    http://www.micron.com/news/product/2...-20_25975.html

    Lightbulb MDD Liquid Cooling

    PowerMac G4 Dual 1.42GHz.

    The machine has been overclocked to 1.50GHz (although we did have 1.58GHz going for a while) and is kept cool with an Aquagate Mini R80 using Steve Smedley's copper shim and stainless steel plate (detailed in an earlier post to xlr8yourmac.com). The full details are in the G4 Renovation section on my website:

    http://roobarb.dfpx.co.uk/

    There have been no case modifications made (although one very minor change may happen soon) and everything is contained within the machine. Still some tweaks and improvements going on, which will pop up on the site once they're done, but there's a fair bit of info on there about the various fans and components in the FW800 G4 which hopefully people will find useful.
