interesting when you say "they do run the 30 inch cinema display" is that all 6600 GT's or only the Sparkle and Galaxy ones?
No. DVI on all 6600 GTs i tested was Dual Link. But for the ones which have two, only one of them is, as, unlike the 6800 Ultra OEM, these cards have no external TMDS.

For that, i had great hopes in the 6800 XT, i posted in the other thread. But sadly this one's DVI is not Dual Link. Otherwise it would be the by far best card, able to run in a Sawtooth. Performance in benchmarks is 10 to 20% better than a Radeon 9800 Pro's.
since IIRC the 6600 GT and 6200 ROM's are from the same base Mac card ROM (6600 PCIe IIRC?)
Yes. ...and for the 64k 6600 GT ROMs i just transferred the complete BMP-section from one of the 128k ROMs to one of the other card's ROMs which allready where small. 6200 or 7800 GS. I don't really remember exactly, cause it's more than 10 years ago. Also the softstraps an some checksums had to be adjusted. But after that they worked.

Replace it :)
Dont have one of the XFX anymore. But in my Quicksilver i am running one of the (also Dual DVI) Galaxys completely quiet. As the card hangs just in front of the 120mm case fan, when the door is closed, this works fine so far. Just had to cut some of the fans housing to not collide with the heatpipes.

Cooler is of some Gigabyte "noiseless edition".

Yeah I was not expecting there to be a Dual Dual link 6600 GT, but interesting to hear that all 6600 GT's in your testing can do dual link DVI :) I always thought it was only one or 2 specific ones

ill defo have to nab me 6600 GT at some point now knowing this :)


as a side note although not AGP 2x compatible sadly, (I say that but some photos show a universally keyed card or one where although its not keyed the pins are missing as if it should be...)

there is the Quadro FX 4000, which is basicly a Quadro version of the Apple GeForce 6800 GT Dual Dual Link card

I remember MacVidCards did say he managed to flash back in the day but I dont think anyones done one recently

but AFAIK this is the only Dual Dual Link DVI option for a PowerMac G4 (well in theory you could hack an Apple 6800 GT/Ultra into a G4 but that would require soldering wires to provide power from the AGP Pro pins you have just hacked off LOL)


speaking of Dual (but sadly not dual link!) DVI cards, The Quadro FX 600 PCI card is another one I want to try and flash or see someone flash, its a Quadro version of the GeForce FX 5200

but it crucially has external TMDS transmitters (like the apple FX 5200 Ultra) so is not plagued by the weak TMDS transmitter built into NV30 cards

if one could be flashed it would give the G3 Blue and white a Dual DVI card :)

hmmmm.........

 
hmmmm.........

Sorry, that is Quad VGA. It's and interesting card with two NV44's and some large chip I've never seen before on the front.

I wonder if that is a PCI bridge and this card has not only dual NV44's but it shows up on the PCI BUS as two devices?

If it may have dual EEPROMs too, we may have found a card that could give two cards in one PCI slot.

The more I look at it, the more interesting it becomes, it appears to have two of everything, and what looks like a POST speaker that likely beeps if you don't connect the 6pin power connector?

Even the 6200 shows up as two devices, as the temp sensor shows up as a device on it's own. 😉

So i tried a ROM with the sensor-part removed. But it didn't help in the OW-Mac.

...and yes! This card looks really interesting! I have never seen a PCI-card, requiering additional power before! And the chip in front reminds a bit on the famous ATI Rage Theater.

yeah there are a few cards like that :) AFAIK all Multi-GPU cards show up as multiple devices, behind just a PCI bridge, and I think most do have separate EEPROMs for each card, but i have never had a good look at one

the biggest one I have seen is the Colorgraphic Xentera GT 8
Colorgraphic_Xentera_GT_8_View2_2020101311819.jpg

which is 4 Radeon 9000's driving 8 display outputs :)

the interesting thing about these cards and the GT4 one which is a dual GPU card driving 4 outputs
is they use Radeon GPU's with the same package as the Mobility cards IE with VRAM on the package

so I do wonder does this card really have Radeon 9000's or are they actually Radeon Mobility 9000's?

either way in theory it should be flash-able, and can you imagine 6 of them in a PowerMac 9600 driving 48 displays? :)

(you can actually find the GT4's for fairly cheap on ebay from time to time)


and yeah a lot of cards from that time period had buzzers to warn you if you had not plugged in molex Power, I have a Gainward GeForce 6800 GT that has one which can goes off randomly at times LOL

Cool, but likely more of a solution looking for a problem.......
There's plenty of use cases for 4 to 8 monitors, e.g. trading. And the fewer slots you need to dedicate to graphics cards, the better. :)

I've had an ATI FireMV 2400 which does use two M9s (Mobility Radeon 9000). GPU-Z identified them as such and I had to use Omega drivers (or the provided ones).

I also own a Matrox G200 Quad MMS which has four G200’s with 8 MB VRAM each behind a PCI bridge. No fan or heat sink so you get a good look at the chips. This was actually the card shipped with the earliest revision of the IBM T221 (DG0 aka T220).

Did you load the Mac OS from 8 track?
No. It was connected to the TV-Out of a Radeon 9800 Pro, sitting in a G5 via S-Video which goes to the input-card of the splitter (check the single black cable to the lower right of all the grey ones). Now i even have a HDMI to S-Video converter box. So i can directly connect it to my 2010 Mac Pro. Resolution is 1024 x 768. So a pixel is about one Inch in square.
