But as the above info indicates, there are ingredients available, to convert a PC 6200 to operate in a Mac. Click to expand.The 6200 is not a great gamer card.

This site, for example, doesn't have your Quadro2 Pro in the list. You really need to find a web site, where someone has been keeping track of video card BIOS files, to solve the second part of the project. A PCI video card is handy to have around, when you're flashing a card like that.īy keeping the LCD monitor connected to the FX5200 PCI, I could watch while the flasher updated the AGP card. I installed a FX5200 PCI video card, so I could see the screen while the AGP 9800Pro card was installed in the AGP port. 2) You need a different ROM image, to flash into the card. So you wouldn't want to get tape on that pin (the pin would be right next to 3a). The TYPEDET# signal on 2a is still present, and the video card uses that to indicate which voltage to use (1.5V/3.3V), in cases where that is an option. If you tape the pins, the card may run at AGP 4x. I hope the pins don't actually carry ADC power. It could be for logic signals related to turning on an ADC monitor.
In conclusion, in your case 1) Research the G4 computer, and the purpose of 3A and 11A custom wiring. I'm not sure when or whether the chipset is required to use those features or not. I re-enabled the path for DBI_HI and DBI_LO, but it didn't seem to make any difference. The other two resistors, are related to dynamic bus inversion. That allowed my Mac AGP 4x video card, to operate in the PC at AGP 8x. By changing those, I did the equivalent of removing the tape from pin 3A and 11A (because I went from Mac to PC and not the other way round). Two of the resistors are related to pin 3A and pin 11A. I changed a total of four resistors on my video card. Obviously, the card is a small step up from the GTX 260 placing more closely with the GTX 280. It is more difficult in the reverse direction (PC video to Mac video), because sometimes the EEPROM is too small to hold the flash upgrade. The ZOTAC GTX 275 here offers 896MB of 448 bit GDD3 video memory, 240 Stream Processor Cores, 633 MHz Graphics (Core) Clock, and a 2268 MHz Memory Clock frequency. The flashing program took care of the details, and I knew from checking the part number, that the EEPROM was twice as big as was necessary. I didn't need to change any declaration resistors, that control the sizing of the EEPROM.

So you have to match a BIOS intended for the particular RAM chips and their clock speed limitations, when selecting a BIOS code to use. I had a number of video BIOS to choose from, and one thing to be careful of, is on the ATI cards, the BIOS controls the video card memory timing. There was no problem flash upgrading the card with a PC video BIOS. The 9800Pro Mac has an EEPROM twice as big as the PC version. I am currently using a Mac 9800Pro in the PC I'm typing this on. ) Sample of a web site addressing flashing the video card. ( This site used to have some pictures as well, but the original link is gone. People taped the pins to insulate them, as one workaround. On certain AGP Macs, those are used for non-standard purposes. It sports a super shiney black fan shroud over the entire length of the card that takes up two PCI slots.Ĭlick to expand.Pin 3A is GC_DET# on an AGP 8x card (AGP30 spec) Pin 11A is MB_DET# on an AGP 8x card (AGP30 spec) On the AGP20 spec, both those pins were 'reserved' by the AGP standard.
It is essentially the same exact size as the older 9800 GTX series.
The GPU is operating at a frequency of 633 MHz, memory is running at 1134 MHz.īeing a dual-slot card, the NVIDIA GeForce GTX 275 draws power from 2x 6-pin power connectors, with power draw rated at 219 W maximum. NVIDIA has paired 896 MB GDDR3 memory with the GeForce GTX 275, which are connected using a 448-bit memory interface. It features 240 shading units, 80 texture mapping units, and 28 ROPs. The GT200B graphics processor is a large chip with a die area of 470 mm² and 1,400 million transistors. Even though it supports DirectX 11, the feature level is only 10_0, which can be problematic with many DirectX 11 & DirectX 12 titles. Built on the 55 nm process, and based on the GT200B graphics processor, in its G200-105-B3 variant, the card supports DirectX 11.1. The GeForce GTX 275 was a performance-segment graphics card by NVIDIA, launched on January 15th, 2009.
