It's nice to finally have it on the G5 CPU, but good luck finding a PowerMac G5 with an ATI graphics card.

What is so hard about it?

I think it has PCI Express, so can just swap them over.

I believe it has to be flashed for Mac usage too, doesn't it?

Guys, A ! G ! P G5 Macs  with Radeon GFX are easily found on EBay or elsewhere.... so why don't you just pick up one of those ?
1. Make an announcment.
2. Wait a while.
3. Check if it can actually be done.
4. Wait for someone else to do it.
5. Start working on it while giving out hillarious progress-reports.
6. Deny that you have ever announced it
7. Blame someone else

I know you can flash some of the nvidia cards, but I am unsure on the ATI cards.  The best ATI card released for the PCIe G5 is the X1900.  Something like this:

http://www.ebay.com/itm/Mac-Edition-G5-PCIe-ATI-Radeon-x1900-256MB-Video-Card-/270620079478

I believe the best nvidia officially released was the OEM 6600 but I have seen 6800 and 7800 ones, perhaps those are flashed firmware as I have seen some mentions of that.  Some links that may be of use to you all:

http://www.everymac.com/systems/apple/powermac_g5/faq/powermac-g5-number-type-speed-pci-pci-x-pcie-slots.html

At least with the PCI-X based G5s you can probably use some regular AGP and PCI Mac video cards.

I have a quad G5 with a 6600, might upgrade to an X1900 one day but I'm on the fence about that.

Great news about the MOS progress for the G5 Poweracs.

About the LCS issues...

I own a G5 Quad. The LCS on it is still running fine, with no leaks, or issues.

AFAIK, the latter produced LCS G5 Powermacs have an improved LCS system over the kind that was originally released and is/was prone to more frequent leaking and issues.

I did however see in general even the G5 Quad (which falls under the latter produced G5 systems category) mentioned over the internet as causing issues and leaks, so I guess no LCS G5 Powermac is completely immune to risks of LCS issues.

Does anyone have any feedback about their LCS system on a G5 Quad?

I will rebuild one of the LCS blocks on my spare G5 2.7 dual tower. I think the Delphi ones were known to leak.  After overlooking the tutorial it seems its feasible to easily rebuild them. Gonna be a hard ass and use 90% distilled water and 10% automotive antifreeze. Replacing all tubing and installing a separate tube to fill up the radiator with.Gonna flush/clean the whole system and rip apart the pump and clean it the best I can with a toothbrush/rubbing alcohol.

Mine is a Dual 2.7 with the LCS, not an issue to date.  Sleeps during the day and runs the BOINC client over night - heats the room nicely!  Waiting for MorphOS...

There is an update from Piru regarding the benchmarks, including numbers from a 2.5GHz G5 system!

:)

Quote
Benchmarks were updated again. After some tweaking 2.0GHz G5 lame is now 2secs faster (using the latest lame version with altivec patch and built for G5 specifically).

Also, the graphs now include 2.5GHz G5 results from my Power Mac G5. 9 seconds for lame, 39.9 seconds for mplayer.

http://sintonen.fi/pics/mplayer_benchmark.png


Wow, the 2.5GHz G5 is TWICE(!) as fast as the X1000 in the lame test, and ~75% faster in decoding the H.264 full HD movie! :banana:

And it's not even the fastest G5 either... :D

It has been said before, but should be said again — The MorphOS Team for sure made the right decision when going for those cheap, widely available second hand Mac machines.

That was clearly the winning move!

:D
MorphOS is Amiga done right! :)

Some info on coolant leaks and repairing/rehauling:

leaks: http://xlr8yourmac.com/systems/G5_coolant_leaks.html
repairs: http://xlr8yourmac.com/systems/G5_CoolantLeak_Repair/G5_CoolantLeak_Repair_p1.html
other g5 articles: http://xlr8yourmac.com/systems.html#g5

Lotta blah blah blah on the leaks page but it at least has some pictures so you know what to look for.  The Panasonic units were used later on and seem more reliable than the Delphi ones.

Any coolant system can break down, seals leaking, pump dying, etc.  It's probably just a matter of time.  My G5 quad is used pretty rarely and I don't know how used it was before I acquired it.  No signs of leaking so far, at least.

The only faster one for single-processor use is the 2.7, which isn't that much difference. Still, not too shabby at all ;)
