    PM G4 motherboards

    is that ever the case for Digital Audio? I thought that was just when installing DA/QS CPUs in a Sawtooth/Gigabit Ethernet

    Simple Quicksilver System Bus speed hack

    Moral of the story, don't use solder bridges or switches in place of resistors? I mean I knew it wasn't ideal, never knew it was as bad as a brick vs a nail-gun. I've just been following guides I've found on the procedure, I do not have an intimate understanding of electronic components...

    Simple Quicksilver System Bus speed hack

    If anyone can't tell, my favorite thing to do with old Macs is overclocking bus speeds, so I really appreciate this post @herd. I was oblivious to these clock generators on G4s. Are you saying these were actually populated on Apple CPU modules from the factory? What do you mean by fighting...

    Simple Quicksilver System Bus speed hack

    It looks like a 4 position dip switch can be installed in that location. Is it possible to utilize that in this situation? On the Sawtooth, there were 4 resistor locations (and how every many resistors in whatever positions for the desired bus speed, always 100MHz as sold) on the underside of...

    Overclock G4 Gigabit 500MHz DP Processor Card – Help with jumpers

    May I suggest you try OC'ing your bus to 120MHz? Link on the procedure is in my sig. If your CPUs are 7400s (which they appear to be), and not 7410s, then I don't think you'd get 600MHz, and 550MHz would be cutting it close. 7410s were good overclockers, 7400s were not. That said, I...

    Simple Quicksilver System Bus speed hack

    There is an OF variable you change to tell it the bus speed is 150MHz (or whatever speed you want). There was a somewhat widespread (and incorrect) belief in the past that this OF change was a software overclock, with multiple people saying "it feels faster".

    Simple Quicksilver System Bus speed hack

    On the plus side, I am pretty sure PC150 exists, but is really rare (none on eBay searching "PC150 RAM"). I feel like homebrew PC150 shouldn't be too hard. fwiw, my 120MHz bus Sawtooth would not boot with any of the PC100 I had.

    Are you sure that exists?

    Simple Quicksilver System Bus speed hack

    I ran into a similar problem of the OS reporting incorrect bus speed after overclocking my Sawtooth to 120MHz. Had to confirm with Macbench/Xbench (CPU benchmark was 20% faster, memory about that too).

    PowerLogix 1.1GHz 750GX ZIF, afraid of chipping the die

    Neat. I noticed it had a temp reading but always dismissed it as inaccurate. First off, still on the 520MHz 750L. It normally says 71F (22C), which is like exactly room temperature, so I sorta dismissed it as not accurate. But actually these G3s are so low power I can believe that's not far...

    PowerLogix 1.1GHz 750GX ZIF, afraid of chipping the die

    Does anyone know if the 750GX has temperature sensors, and if so, are they readable from OS 9, OS X, or Linux?

    Rage 128 Identification, and Daughterboard

    So does that mean both of these cards would be considered Orion? Sorry if I'm dragging this out, I just expected each card to have a unique model name. The reason I thought it might be a Pro is because it seems to be the next step up from the GL, and, depending on your definition of slightly...

    Is the heatsinked one possibly a "RAGE 128 Pro"?

    Rage 128 Identification, and Daughterboard

    I have 2 very similar Rage 128 cards, both received in Blue G3 towers. One, on the chip, says "RAGE 128 GL", so I think that one is identified. It also has an identifying number of 630-2858 The other has a heatsink over that chip, which just reads "..RAGE 128", and an identifying number of...

    Overclocking 604 Processor Cards

    I believe you are mistaken about what the 1s and 0s represent. Sorry if I misunderstood you or am incorrect in this conclusion, still working this out, and my ability to understand what people are trying to say is often lacking. I believe a 1 indicates no jumper, and a 0 indicates a yes jumper...

    Quietest SCSI Hard drive

    just want to confirm if thats the model number, as theres an XP34300W on eBay thats somewhat cheap. But yeah those prices I'm seeing on Quantum XP in general are pretty crazy

    Quietest SCSI Hard drive

    I have a PCI SATA Hard Card, regular PCI SATA card, and ZuluSCSI. But I do want to run a 50-pin SCSI HD, too. The only one I have now is a 2GB Quantum Fireball. However, it is way too loud for me. It could be because it's old, but it works fine. Are there quieter SCSI drives?

    Overclocking 604 Processor Cards

    according to one article online, you can not use an Apple card in a Power Center, and tho the article doesnt outright say it, it looks like you can use a Power Center card in an Apple. "The Catalyst architecture requires the DTRTY line from the CPU. As none of Apple's upgradable systems require...

    Overclocking 604 Processor Cards

    I'm actually putting it into my 7300, but I am happy to hear you think 270MHz will be fine. I have 48MHz and 50MHz crystals, so I could: 240/48 250/50 264/48 275/50

    If I had to guess, Id say its R1 to R4, corresponding to CFG0 to CFG3
