MDD G4 odd start/restart behavior - new video card
Hello! I have a MDD G4, 1.25 GHz DP, 10.5.8. Last night I installed a Radeon 9800 Pro 128M AGP (DVI) card, replacing the stock Radeon 9000 68M (ADC). My main motivation for doing this was to have a 128M card, so as to run a larger monitor at full resolution. I didn't really look for the 9800 Pro, but I found it at a good price, and the info I found indicated that it would work in the MDD. One salient point if you're not familiar with the 9800 pro - apparently the AGP bus doesn't provide enough power for it, so it requires a secondary power connection from a molex connector, using a splitter from one of the hard drive power connectors. In fact, the card does work, more or less. I get great display at 1920 x 1080. But there are two problems. If I shut down the machine and then try to power it back on, one of two things happens: (1) it won't power on at all. I press the power button, and literally nothing happens. (2) It will power up and give me the boot chime, but then show in the center of the screen a small picture/icon of the Radeon card, with a little ATI logo in the corner, and in the upper right corner of the graphic a flashing red molex connector and its wires, signifying that it's not getting power from the molex. Of course, it was working and getting said power before I shut it down, so something changed on shutdown, it would seem. The solution I have found to this problem is (if it powered on and gave me the flashing molex icon) is to manually power it down with the power button, and (if it didn't power up at all just do this) unplug the machine for 30 seconds to a minute, then plug it back in. Then it will start up normally. Furthermore, if I try to restart, I invariably get the flashing molex graphic. I then have to manually shut down, unplug, replug, and power on. The machine seems to sleep OK. I can put it to sleep and wake it, seemingly regardless of how long it has been asleep, with no problem. When this first happened, I thought perhaps a cable or something was physically pressing the motherboard reset button (it is pretty cramped in there). But no, the button is clear. I never had these problems with the stock Radeon 9000 ADC card. So, what is going on? Something seems to be messing with the card's ability to get power. Is something interfering somehow with the machine's power management? I'd like to use the 9800, but if I can't properly start up and restart, that's a pretty big PITA. Is the 9800 just too much card for the MDD? Is there some solution to this problem that will allow me to use the 9800? Or should I stick with the 9000 or another ADC card? Thanks!

Re: MDD G4 odd start/restart behavior - new video card
Kris: My understanding is that the tape on pins 3 11 issue applies to PC versions of the 9800 card flashed over to Mac, not to *original* Mac edition cards. This is an original Mac edition card. Cards that have the pin issue will cause the machine to not power up *at all * if the pins are not covered. My machine will power up with the card installed. The problem is on restarts, or a power up after a shutdown (unless you unplug and replug the machine). Furthermore, the flashing red molex graphic indicates that the card is somehow not getting power, or it thinks it isn't. I may, if I can't get anywhere in another way, try the pin thing. But I don't think that's the problem. Thanks, Rob J.

This is an original Mac edition card. I don't think the pin 3 11 issues was PC vs. Mac cards, I thought it was using AGPx8 cards in AGPx4 Macs where the Macs were made OEM for ADC Mac cards and pins 3 11 were appropriated by Apple for ADC power that somehow screwed up AGPx8 cards in these ADC Macs? I could be wrong? -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.

Then it will start up normally. Well, it seems having to do with hot (re)start. Letting it cool down (even just a bit), seems helping;but I cannot think what heat has to do with it. Unplugging might reset something or let a memory chip lose its content; but, again, doesn't make much sense. Only thing I can think of, when the Mac is starting, the 9800 could compete with the hard drive (on the same power line) for power, since hard drives need the most power when spinning up; once it has started, the shared power is enough for both to work. What else is connected on the same power line where you put the splitter? Did you try to put the splitter on the optical drive's power line? (it should not require power at boot). Is the 9800 just too much card for the MDD? I think that 9800 Pro was made for G4 and G5 Macs, so it *should* work. I wonder what could be wrong in your MDD's power department. Have you got many peripherals inside it (HDs, cards...) that are sucking power? Maybe the power supply is overloaded. -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
