A power switch includes an OC detection circuit, a UV detection circuit, and an OC indication circuit. The OC detection circuit detects an over-current in the power switch, provides an OC flag in a first state when no over-current is detected, and provides the OC flag in a second state when the over-current is detected. The UV detection circuit detects an under-voltage in the power switch, and provides a UV fault indication in a third state when the under-voltage is not detected, and provide the UV fault indication in a fourth state when the under-voltage is detected. The OC indication circuit provides an OC fault indication in the third state when the over-current flag is in the first state, and provides the OC fault indication in a fifth state when the over-current flag is in the second state. The UV fault indication and the OC fault indication are configured in a wired-or to provide a common fault indication.

An information handling system includes a memory module having clock inputs. Clock generation logic includes clock outputs, each clock output coupled to an associated one of the clock inputs. The information handling system determines whether the memory module is in a first configuration or a second configuration, enables a first number of the clock outputs when the memory module is in the first configuration, and enables a second number of the clock outputs when the memory module is in the second configuration, the first number being different from the second number.
