I recently had some low-level problems with my s900 that turned out to be pretty serious. I troubleshooted the problem to the PCI bridge chip, that controls/effects the bottom 4 PCI slots on my motherboard. The computer and its components all work great except when any card is added to the bottom 4 PCI slots, which results in the computer chiming, but not doing anything thereafter. The chip heats up to where I could burn myself if I touch it for extended periods, so it's obviously dead.
So my question is this: what might have caused this problem? I think that it could be attributable to my overclocking the system bus (through my XLR8 g4 ZIF) to ~57 mHz to get my G4/450 to run at 510mHz. I know that overclocking the bus affects all components, including the PCI bus. Another possibility that came to mind was that my card is not the SSE edition, which obviously is fully compatible with the bottom 4 slots. My card is the regular edition G4 MPe from XLR8 which I heard exclusively enables the bottom 4 slots on the s900 and not any other 6-slot Apple, since it uses a completely different controller rather than a redundant PCI controller in the non-clones from which it is based. Since this is a supermacs list, I thought that you guys might know a good place to get a replacement motherboard or whole computer for my s900. I originally ordered this system bare-bones from poweron.com, but they no longer offer it. I have tried the trading list here at LEM and eBay and want to know if there is any place else (or the best place) that I can purchase one from.
