Hello again:
You'll recall my travails last week with the Radeon 9800 Pro that I
couldn't get to work properly/reliably in my 1.25 gHz DP MDD. I finally
gave up on it, and reverted to the stock 9000.
But I purchased a 9600 XT on eBay, which I received yesterday. The machine
wouldn't power on with the card until I taped pins 3 11, which didn't
surprise me. But I taped the pins and the machine started right up, and the
card works fine, with a couple of caveats, which I'll get to in a moment.
However, much to my chagrin, I discovered that the 9600 XT, and presumably
other AGP/ADC video cards meant originally for the G5, does not have its
ADC connector in the same place as the 9000, or other G4 AGP/ADC cards. The
ADC connector for the 9600 is further back on the card than that of the
9000. Color me stupid, but, never having poked around inside a G5, I did
not know that the G5 and G4 had different physical locations for the ADC
connector. I figured ADC was ADC. D'oh!
So, though the card works, I've really gained nothing by getting the 9600.
I wanted an AGP/ADC card into which I could just plug my Apple 23 inch ADC
display. I can use my DVI - ADC adapter with the card, but what I wanted
was a straight ADC connection.
So, first question: my subsequent research indicates that the only AGP/ADC
card that offers Core Image hardware acceleration, and will physically work
with the ADC connector of the MDD, is the Radeon 9700, which, apparently,
had a version that was designed for the MDD. Is this correct, or are there
others I'm not aware of?
Furthermore, there is one issue with the 9600 when I use it with the
DVI-ADC adapter and my 23 inch cinema display. For some reason, and this
*only* happens with the DVI-ADC adapter and the cinema display, when I load
pages in Safari that have Flash content, Safari either hangs and becomes
unresponsive, or quits altogether. I then get a dialog that says Safari
has quit unexpectedly. This may have been caused by the Flash 10.x
plug-in. This only happens with the 9600 - DVI - ADC - 23 inch cinema
combination. Any ideas what is going on here? I am guessing, but perhaps
for some reason the Core Image hardware acceleration of the 9600 (which the
9000 doesn't have) doesn't play well with Flash and ADC? I can't imagine
why, but there it is.
Finally, my second question, which may be moot, but: has anyone ever tried
to somehow adapt the ADC connector of one of these G5 ADC cards to the ADC
connector of an MDD? It seems to me that it could be done and could work.
The ADC connector only has two leads, which supply power for the display,
correct? It seems to me that you might be able to come up with some kind of
franken-connector or jumper that would let you go straight ADC. Anyone know
anything out there?
Thanks,
Rob J.
