*HelpHelp for ECC Memory Setup*ECCMem


The ECC Memory Setup service enables a user to monitor and manage ECC memory. User-selectable options are:

You can also set the single-bit error threshold value that will trigger the NMI if the Single-Bit Error Threshold option is selected.

Note: If a NMI occurs, it might halt your system.

For detailed instructions on configuring ECC Memory Setup, see the Configuration Help topic.

Note: ECC Memory Setup is available for use only on those systems that have ECC Memory installed.

Single-Bit Error Scrubbing

Activating the Single-Bit Error Scrubbing option instructs ECC Memory Setup to activate the automatic error correction features of the ECC memory in the system. This will immediately correct any single-bit errors that occur. Selecting this option may cause a slight performance impact on some systems, but ensures greater data integrity. Check your system documentation for more information.

For detailed instructions on configuring ECC Memory Setup, see the Configuration Help topic.

Single-Bit Error Counting

Activating the Single-Bit Error Counting option instructs ECC Memory Setup to keep a running count of all single-bit errors that occur in the ECC memory.

For detailed instructions on configuring ECC Memory Setup, see the Configuration Help topic.

Single-Bit Error Threshold NMI

Activating the Single-Bit Error Threshold NMI option instructs ECC Memory Setup to cause a Non-Maskable Interrupt (NMI) if the number of single-bit errors exceeds the user-specified threshold. An NMI will often cause the system to immediately shutdown, so this feature should only be enabled if the system contains special NMI handling hardware or software.

For detailed instructions on configuring ECC Memory Setup, see the Configuration Help topic.

Single-Bit Error Count

The Single-Bit Error Count field displays the number of single-bit errors that have been detected by ECC Memory Setup during the current session.

Note: The single-bit error count is for the current session ONLY. The count is reset to zero upon restart. If you wish to carry a count over from a previous session, you must enter the error count manually from the configuration screen.

For detailed instructions on configuring ECC Memory Setup, see the Configuration Help topic.

Single-Bit Error Threshold

The Single-Bit Error Threshold field displays the user-specified number of ECC single-bit errors that will be allowed before ECC Memory Setup will trigger a Non-Maskable Interrupt (NMI). If the NMI feature is not active, the Single-Bit Error Count will be reset to zero when the threshold is reached.

Note: An NMI only occurs if you activate the Single-Bit Threshold NMI option.

For detailed instructions on configuring the ECC Memory Setup, see the Configuration Help topic.

Address of Last Error

The Address of Last Error value is the specific memory address where the most recent single-bit ECC memory error occurred.

For detailed instructions on configuring the ECC Memory Setup, see the Configuration Help topic.


Configuration Help

To configure ECC Memory Setup:

  1. Select the actions that you wish ECC Memory Setup to perform. Available options are:
  2. Change the Single-Bit Error Count, if desired.
  3. The Single-Bit Error Count field displays the number of single-bit errors that have been detected by the ECC memory Setup during the current session.
    Note: The Single-Bit Error Count is for the current session only. The count is reset to 0 when the computer is restarted. To carry a count over from a previous session, you must enter the error count manually from the configuration screen.
  4. If you have chosen the Single-Bit Error Threshold NMI option, set a Single-Bit Error Threshold value.
  5. The Single-Bit Error Threshold field displays the number of ECC single-bit errors that will be allowed before a Non-Maskable Interrupt (NMI) will be triggered.
    Note: An NMI will occur only if the Single-Bit Threshold NMI option is activated.
  6. When you are satisfied with the selections you have made, select Save.
  7. If you are not satisfied with the changes you have made, select Reset to recall the previously saved ECC Memory configuration.

All functions of ECC Memory Setup may also be accessed from your command line. For more information, see the Command Line Help topic.

Command Line Help

All functions of the ECC Memory Setup can also be accessed from your command line, using ECCMEM.EXE. The command line format for ECCMEM.EXE is:

ECCMEM < /INIT > < /SCRUB:<ON OFF> > < /THRESH:<ON OFF> > < /COUNT:<ON OFF> > < /QUIET > < /COUNTVAL:number > < /THRESHVAL:number >

Where:

INIT
- Causes the ECC memory to be initialized to the saved settings
*/SCRUB:<ON OFF>
- Enables or disables single-bit error scrubbing
*/THRESH:<ON OFF>
- Enables or disables single-bit error threshold NMI
*/COUNT:<ON OFF>
- Enables or disables single-bit error counting
/QUIET
- Causes ECCMEM to generate no textual output
/COUNTVAL:number
- Sets the single-bit error count to a given value
*/THRESHVAL:number
- Sets the single-bit error threshold to a given value

* = This option updates the saved settings to the value provided. Upon restarting the system, the saved settings can be used to configure the ECC memory through the /INIT option.
