That appears to be the case. I have more than 4GB (I think 8.5GB) in my
PowerMac11,2 and it only recognizes 2GB. There are some issues with the
SATA controller as well that I have mentioned in threads a few months
back on this list. I purchased some more SATA controller hardware to see
what I can figure out but have not had time to work on it further.

I bought a Radeon X1900 Mac Edition which is the fastest card that could
be supported on a PCIe PowerMac G5 and there are still problems. See
this thread for where things need to go:

I have not had time to troubleshoot that further either and I am really
out of my depth but willing to try to determine whatever I can. I do not
have any problems with a PowerMac7,3 I have and also purchased a Radeon
9650 Pro for it which worked pretty well as I posted:

I would love to get the PowerMac11,2 fully supported with PCIe Radeon
graphics and hopefully I can help with that process.
