| Radeon X800XL in PowerMac G4 Sawtooth AGP |
Posted by: EmeraldXB on 2026-03-28 21:11:57
A Few Months ago I rescued a AGP Sawtooth G4 from the side of the road near where I live. Found it with a 1.5Ghz CPU Upgrade Card and 1GB of Ram. Unfortunately the GPU is the original rage 128 that it came with from the factory. I’m wanting to do a GPU upgrade on it but am not willing to pay the prices that are being charged for them. My friend has a Diamond Viper X800XL that he’s willing to give me. My question is does anyone know if it possible to mac flash this card for EFI support? |

Looks like you might be out of luck with a Sawtooth re: X800s in general (not sure about the Viper X800XL specifically): http://themacelite.wikidot.com/compatibility |

Do you have a picture of the card? It is probably keyed for 4x/8x. I think the 9800 is typically the fastest card for the AGP, but some of these are also 4x/8x. I think I read where someone added a notch and it worked fine (under dos). |

He also has a 9600 SE but that ain’t gonna work either. Guess I’m gonna have to keep an eye out for a 9800 as that seems to be my best bet. |

If you look up Diamond Viper Radeon x800XL AGP you will see what it looks like though from my research it seems the 9800 is gonna be the best I can run. |

I think that the bus speed (100MHz) & 1 GB RAM are going to be your bottlenecks if you want to run Mac OS X 10.4.
I'm even sure if this G4 supports Mac OS 10.5 tbh.
This will make gameplay disagreeable even if you have one of the best Mac OS X AGP cards.
And the Radeon X800XL won't support 3D games in Mac OS X 9.
I'd keep that card for an unloved 1.8 or 2.0Ghz DP PCIX G5. Then it'll be allowed to roar.
Why not look for a Radeon 9000 Pro AGP card and turn the G4 Sawtooth into an excellent Mac OS X 9 machine? |

Why not look for a Radeon 9000 Pro I'd second this. For a Sawtooth it's probably all the performance you can really use (plus they're not too hard to find or crazily priced), with better compatibility than the ostensibly faster cards.
(Although now I think about it I'm not sure I've tried that combo... I'm assuming the 9000 Pro plays nicely with the Sawtooth.
🤔 I hope someone here knows for sure?) |

I have an AGP with an apple 9000Pro card that came from a MDD. I think a flashed nvidia 6200 would also work. |

I'm not sure whether the X800XL could be flashed. As far as I know, the only official Mac AGP X800/X850 cards are native AGP (R420 core). The X800XL uses a different core (R430) without AGP support, with a PCIe-to-AGP bridge chip.
I've been buying and flashing AGP video cards for G4s for a while. I have a larger pile of good working cards sitting around at this point than I probably should. I could sell you a 9800 Pro or something else if you like; send me a PM. |
