This information is gold. And I highly appreciate it as I have a G5 that is dead due to this exact problem. I have a working logic board but can't change it out until my tools arrive.
Would be great if I could repair the existing board using the wonderful info you've provided but I don't have experience with things like that.

Wow man this is some amazing information, thank you for sharing this. My G5 DP 1.8GHz recently died from this...tried the reflow and while it worked it didn't work long enough before it died and I sold it off.
Now that you highlighted the backside heatsink on the logic board all of this makes perfect sense to me. Right now it is the hottest part of my DC G5, it never drops below 130F.

That's interesting but remember there are specific ram standards for Powermac G5's. When I owned that same machine, I had to buy brand new ram to make it work and even with eight gigs of ram it was too slow anyway. Worked my way up to a Quad.
The idea that a reflow is needed makes sense and there used to be a company in Arizona who would reflow the broken memory slots on Powerbook G4's, they would reflow the video chips on iBook G4s and probably (if they are still in business) would reflow the boards on these PMG5s.
Still PMG5s were ridiculously notorious and picky about memory. The need to seat the ram chips in matched pairs, in ascending or descending order of size, was also a pain.
