Hard errors typically indicate a problem with the DIMM. Although hard correctable memory errors are corrected by the system and will not result in system downtime or data corruption, they indicate a problem with the hardware. Soft errors do not indicate any issue with the DIMM. A soft error occurs when the memory data, ECC bits or both are incorrect, Such error gets resolved automatically by the system when the error condition is corrected. When Correctable Memory Errors (CME) occur, try the following steps: Steps 1 Update the BIOS and firmware. For more information about updating BIOS and firmware, see your systems documentation at www.dell.com/support 2 Remove and reinstall the memory modules. 3 Run MP Memory test to confirm the failure. 4 Try isolating the faulty memory module by swapping with another identical memory module from the system or installing the module in a different slot. Memory errors after system reboots Issue: Memory errors at POST after system reboot. Resolution: 1 Update the system BIOS to the latest version. 2 For more assistance call Dell Technical Support. Memory errors after upgrading memory modules Issue:After upgrading memory modules, memory errors occurred. System is able to continue after pressing F1. Solution: CAUTION: Ensure that all configurations and data is backed up prior to updating BIOS or Firmware. 1 Update the BIOS version to the latest version Troubleshooting hardware issues 65

Correctable memory errors in the system logs
About this task
Correctable errors can be
classified
as hard errors and soft errors. Hard errors typically indicate a problem with the DIMM. Although hard
correctable memory errors are corrected by the system and will not result in system downtime or data corruption, they indicate a problem
with the hardware. Soft errors do not indicate any issue with the DIMM. A soft error occurs when the memory data, ECC bits or both are
incorrect, Such error gets resolved automatically by the system when the error condition is corrected.
When Correctable Memory Errors (CME) occur, try the following steps:
Steps
1
Update the BIOS and
firmware.
For more information about updating BIOS and
firmware,
see your systems documentation at
www.dell.com/support
2
Remove and reinstall the memory modules.
3
Run MP Memory test to
confirm
the failure.
4
Try isolating the faulty memory module by swapping with another identical memory module from the system or installing the module in
a
different
slot.
Memory errors after system reboots
Issue:
Memory errors at POST after system reboot.
Resolution:
1
Update the system BIOS to the latest version.
2
For more assistance call Dell Technical Support.
Memory errors after upgrading memory modules
Issue:
After upgrading memory modules, memory errors occurred. System is able to continue after pressing F1.
Solution:
CAUTION:
Ensure that all
configurations
and data is backed up prior to updating BIOS or Firmware.
1
Update the BIOS version to the latest version
