Why Should I Troubleshoot Every Memory Problem? Accurate diagnosis of system memory problems in ProLiant servers has many advantages, including: • Prevents unnecessary hardware replacement. • Prevents the return of parts that test NFF (No Fault Found). • Prevents server downtime. Best Practice: Many - HP ML530 | System Memory Troubleshooting Best Practices for HP ProLiant Servers - Page 3
. Therefore, further troubleshooting is necessary to determine which specific DIMM is failing. Use the LEDs as a tool in identifying that a memory problem may exist, but do not rely solely on the status of the LEDs to determine if hardware should be replaced.

System Memory Troubleshooting Best Practices for HP
ProLiant Servers
Accurately troubleshooting system memory issues in ProLiant server configurations is an important process that
can help prevent unnecessary replacement of hardware components. In addition, accurate problem diagnosis
prevents customers from experiencing unnecessary downtime while waiting for hardware that may not need
to be replaced.
Following standard troubleshooting guidelines and using them each time a memory issue is
suspected helps to establish this.
HP has developed several methods for troubleshooting memory problems in ProLiant servers.
The purpose of this white paper is to assist HP customers in troubleshooting system memory problems by
successfully isolating the specific DIMMs causing the problem. This helps to prevent nonessential replacement
of unaffected DIMMs or, in some cases, entire banks of memory. In addition, effective troubleshooting can
help determine if a firmware or other software download can resolve a problem without replacing hardware.

•
Why should I troubleshoot every system memory problem?
•
How can I tell if a memory problem has occurred?
