Last weekend I bought a Sun E420R that had maxed out RAM and CPU but once brought it home and powered it on everything was fine until slave CPUs 1-3 started timing out. I have already replaced the motherboard and tested each CPU in slot 0 to make sure that they all work and I still have the same problem. Could this be because the NVRAM is dead or is it another problem?

I have tried looking in the Sun manual and I couldn't find much to guide me to fixing this issue. Any help would be helpful.

After the RAM test the 420R will display CPU Slave #3 timeout for slot 3 and the same applies for slots 1 & 2. It seems like only slot 0 is populated will the machine pass POST. I'm not at home right now but when I get back I'll post the CPU and MB part numbers.
