General memory problems are occurring 
Action:  
Be sure the memory meets the server requirements and is installed as 
required by the server. Some servers may require that memory banks be fully 
populated or that all memory within a memory bank must be the same size, 
type, and speed. Refer to the server documentation to determine if the 
memory is installed properly. 
Check any server LEDs that correspond to memory slots. 
If you are unsure which DIMM has failed, test each bank of DIMMs by 
removing all other DIMMs. Then, isolate the failed DIMM by switching 
each DIMM in a bank with a known working DIMM. 
Remove any third-party memory. 
Run Insight Diagnostics to test the memory.
