Adrian,
So, I was able to pick up some replacement RAM. Doesn't Seem to matter what modules I have where.
Sometimes I get /SYS/MB/CMP0/BR1/CH0/D0 failed. I've tried moving modules and it's still this location.
Other times I get a bunch of errors on multiple locations:

These errors aren't accurate. And it seems to be all the modules on CPU0.
If I power cycle the system I can occasionally get it to boot. I've been able to get Solaris 11.3 installed and I've booted to it a few times.
Also, with the latest build of Debian I was able to complete the install but when it rebooted it still went to Solaris. So I shut it down planning to boot the other disk in OpenBoot but I haven't been able to get it to come back up since.
I'm thinking I may have a more serious issue than just memory modules. OR I have a LOT of bad modules.
I originally had 8 x 4GB modules and I now have 8 x 8GB modules. But I have the same behaviour regardless which modules are installed and in what slots. I don't have a mezzanine card installed. This is just on the motherboard.
