PowerMac G5 issue in Tiger OS: cannot output 2560 x 1600 on my 30" Cinema Display

[sheapuppy]

Hi everyone,

I had been running Tiger OS X 10.4.11 for a long time - very stable for my Classic OS 9 apps. About a week ago, my logic board died so I ended up buying off FB a PowerMac G5 (7,3) with 8GB RAM, Dual 2.0 GHz 970 CPUs, and an ATI Radeon 9200 128MB PCI card. I swapped my 250GB SSD drive and the new G5 booted up with no issues EXCEPT that I can only get 1200 x 800 resolution. I thought maybe it was an issue with the card itself, so I put the original NVIDIA GeForce FX 5200 64MB AGP card. With either card, I can only get 1200 x 800 resolution.

My understanding is that both of these cards support dual link DVI display.

I'm using a 30" CinemaDisplay with the original "W" cord (DVI, USB, Firewire) that came with it, so I'm not sure what's going on? Hopefully someone can help me.

TIA...JP

Neither of them do.

Neither of them do.

Thanks! I could've sworn that they did but obviously I must be wrong (dang AI ! ). Which one would you recommend that doesn't break the bank? I'm mainly using it for Photoshop as I still have an original Adobe CS license!

ATI Radeon 9650 XT (one single-link, one dual-link DVI)
NVIDIA GeForce 6800 GT DDL (two dual-link DVI)
NVIDIA GeForce 6800 Ultra DDL (two dual-link DVI)

Best regards...JP

ATI Radeon 9650 XT (one single-link, one dual-link DVI)

This one. It’s even passively cooled.

I'm not sure where your G5 got that Radeon 9200 from, but I can't find any factory configs with said card online. I also have a PowerMac7,3 (2.3GHz DP), but it has a Radeon 9600 installed. By the way, I wouldn't waste any more time with that FX 5200 if I were you. I installed a 128MB variant into one of my hackintoshes years ago, and it didn't even let me enable the translucent menu bar in Leopard.

If you want something better, get the Radeon 9650 XT (I heard 6800 Ultra cards are rare, and tend to fetch top dollar).

Thanks! I got lucky a couple of weeks ago while looking in FB marketplace. A seller had a damaged G5 for parts - it appears someone had dropped it, and cracked both the plastic cover and side panel. In addition, it had corrosion related to being an LCS 2.5 GHz - one of the CPUs is shot. BUT to my surprise, it came with an NVIDIA GeForce 6800 Ultra DDL GPU INCLUDED!! And best of all, he sold me the entire G5 for $25!!

That said, the GPU card had some damage - some of the caps were missing. I am not sure if it was caused by the drop or some other issue. I ordered the missing caps from DigiKey and did some soldering over this past weekend.

Finally, I had a chance to fire it up last night. I am able to get full 2560 x 1600 resolution!! Woohoo I'm stoked!!

After doing more research, it appears the 9200 PCI was offered aftermarket mainly to be used with Xserve G5 headless units. I suspect the original seller had it left over and just put it in the replacement G5 I bought about a month ago.

There is a website that lists the 9200 PCI as a PowerMac G5 compatible which I'm assuming has the Mac ROM to boot up into a standard PowerMac or Xserve G5.

I've also read somewhere else in the forum that someone was successful in installing a 9200 PCI into a PowerMac G4 running OS 9. Now that's daring!
