ECC fault prediction and pre-failure warranty

When the workstation encounters an excessive number of error checking and correcting (ECC) memory
errors, the workstation displays a Local Alert message. This message contains detailed information
about the errant memory module,enabling you to take action before you experience non-correctable
memory errors. The pre-failure warranty for ECC memory modules enables you to replace these
modules, free of charge, before the modules actually fail. ECC memory modules are optional on selected
HP systems.

Thermal sensor

There are multiple sensors on your workstation:
● One per processor
●
One per memory module (DIMM)
●
One for the system board
●
Some hard drives
The processor thermal sensor is a hardware and software feature that tracks the internal temperature
of the workstation. When combined with HP Client Manager Software, this features notifies the network
administrator when the normal range is exceeded. In this case, the processor clock automatically begins
to throttle. If the temperature does not decrease, the system eventually shuts down.
