Good afternoon. I searched the general desktop forum for an answer to this but didn't find anything.
I have a Precision 690 with a set of memory risers. I have verified that they are properly configured with 4 sets of matching fully buffered 4GB DIMMs, but when I boot, I get an error message that it is booting in single channel debug mode. When I hit F2 and look at the memory menu, it shows that all 16 4GB DIMMs are present, but only 8GB is available.
I bought this refurbished from my university with mismatched DIMMs on what turned out to be risers that weren't fully functional. I replaced the risers and memory. Is there an additional step I am missing to take the machine out of debug mode?
Thank you for the reply. That doesn't help. I have all 16 slots filled, and when I view the memory after striking F2 in debug mode, it shows every slot filled but still only boots in single channel debug mode.
