I removed the original 4 x 1GB memory from our Dell Poweredge 2950 server (we have 2 Xeon quadcore processors). I then added 8 x 4GB RAM.
When booting, the server gives a message saying no memory and boot abort. Also the message "Intrusion" comes at times.
When I put back the original 4 x 1GB, it works well.
What can be the problem?
