I recently got a netboot setup going with a NAOMI 1 and a NetDIMM running firmware 4.02. Everything was going well for a couple hours. I was playing Monkey Ball and Crazy Taxi with no issues. Then at one point during Crazy Taxi, the game froze and the audio was stuck in a 1 second loop. I rebooted the NAOMI, went through checking memory, loading, checking memory, then got an error 31 "This game is not acceptable by main board." I tried several more times with the same result. I ran the RAM test and it all came back good. I ran the DIMM test and got a BAD result for DIMM0. I ran this test when I put the setup together and got all good results.
Here is what I've tried so far:
- Reseat the NetDIMM
- Clean contacts and reseat.
- Open up NetDIMM and reseat RAM and network board.
- Try using the NetDIMM with the top off of the NAOMI (to ensure its fully seated).
- Try netbooting other games (same result)
- Try using the NetDIMM with a CF adapter in GD-ROM mode. I think I got an error 21 or 22 in this mode. It looped through loading and checking memory 3 times before rebooting with an error.
- Try using a different DIMM (not net dimm) with a GD-ROM to try and isolate the issue. It worked with no issues so it doesn't seem likely to be the NAOMI itself.
- Checked voltages. They were running a tad high. 3.3 was running at about 3.4 and 5 was at a bout 5.2. This was not under heavy load, just during the NAOMI splash screen. I did adjust them to 3.3 and 5.1 after the fact.
Could it be that the buffer chip is fried? Would that cause these symptoms? It seems like error 31 could have a lot of causes based on my research.

Edit - SOLVED
TL;DR: I needed a new stick of RAM.
The first stick I bought did not work and failed the same way the original one did. This led me to believe that it might have been something else going on. I replaced the buffer chip and even went so far as to swap my firmware chip over to a completely different base board with no success. I ended up buying 3 more sticks of RAM and found one that worked: Samsung M366S6453CTS-C7A.
I still don't know why my original stick just stopped working and why the second stick didn't work (its one of the verified working ones in the thread mentioned below).
