Another portion:
Sun Ultra 2 UPA/SBus (UltraSPARC-II 400MHz), No Keyboard
OpenBoot 3.7, 256 MB memory installed, Serial #16777215.
Ethernet address ff:ff:ff:ff:ff:ff, Host ID: ffffffff.


The IDPROM contents are invalid

Power On Self Test Failed.  Cause: Memory  


Depending on the exact memory location in the system board, I get different error messages

400Mhz/2mb are the fastest listed supported, no idea if the 450Mhz CPUs will POST or not. What revision motherboard is in your Ultra 2?
 
 
Do you have a capture of the actual POST error messages?

 I should have mentioned that I reseated the ram and swapped known good memory from my Ultra 1 without success. Pulled the Creator card. Reseated the CPU as well. I may buy another CPU as they are relatively cheap and I'd like to go dual as well... What is the top spec CPU for this machine? 400mhz/2mb is listed in the manual (and is what I have), but I seem to recall folks using 450mhz and/or more cache.

Ultra 2's are generally very reliable, I recommend reseating the CPUs and memory if you haven't already.
 
Cheers,

      I finally had a chance to dig into the Ultra 2... and this is my first miss complete miss in getting back into retro computers. "Red State Exceptions" and other memory errors lead me to believe that this machine is irrecoverably sick. So I'm looking for another Ultra 2 machine. 
  The rest of my list: SS1000(E)
  TGX+ Horizontal Creator Series 3 or Elite3d M3/M6
  Tadpole 3200/Cyclequad Sparcplug Dec 5000 Indy/Indigo2 Alpha, RS6k HP 712/100mhz (complete system or logic board alone) Other weird stuff
  
  Still in St Louis
  
  thanks mike
