Abstract: A method and apparatus for synchronizing a time stamp counter (TSC) associated with a processor core in a computer system includes initializing the TSC associated with the processor core by synchronizing the TSC associated with the processor core with at least one other TSC in a hierarchy of TSCs. One or more processor cores are powered down. Upon powering up of the one or more processor cores, the TSC associated with the processor core is synchronized with the at least one other TSC in the hierarchy of TSCs.

Abstract: A processor adjusts frequencies of one or more clock signals in response to a voltage droop at the processor. The processor generates at least one clock signal by generating a plurality of base clock signals, each of the base clock signals having a common frequency but a different phase. The processor also generates a plurality of enable signals, wherein each enable signal governs whether a corresponding one of the base clock signals is used to generate the clock signal. The enable signals therefore determine the frequency of the clock signal. In response to detecting a voltage droop, the processor adjusts the enable signals used to generate the clock signal, thereby reducing the frequency of the clock signal droop.

Abstract: Adjustable thermal management is described. Input to adjust one or more parameters for controlling thermal conditions of a component is received. Temperature measurements of a component are obtained from two or more sensors of the component. A temperature of a thermal hotspot of the component is estimated based on the temperature measurements obtained from the two or more sensors of the component and using the adjusted parameters. Operation of the component is adjusted based on the estimated temperature of the thermal hotspot.

Abstract: A system that includes at least a system memory, a chipset link, and a chipset attached memory is powered down. A boot-up process is loaded in the chipset attached memory. The boot-up process is performed for the system, via the chipset link, by the chipset attached memory. The boot-up process includes loading one or more memory testing applications. The system memory is tested using the one or more memory testing applications loaded by the chipset attached memory.

Abstract: Dynamic range aware conversion of sensor readings is described. A system includes one or more sensors to sense conditions of a component and output sensor readings and a system manager. The system manager is configured to convert the sensor readings into condition measurements by converting the sensor readings into the condition measurements using a first transformation while operating in a first conversion mode or converting the sensor readings into the condition measurements using a second transformation while operating in a second conversion mode. The system manager then adjusts operation of the component based on the condition measurements.

Abstract: Automated memory overclocking is described. In accordance with the described techniques, one or more sets of overclocked memory settings of a memory are automatically selected for performance testing and stability testing of the memory. The one or more sets of the overclocked memory settings are tested for performance of the memory and a performance indication is output for each of the one or more sets of the overclocked memory settings. The one or more sets of the overclocked memory settings are tested for stability of the memory and a stability indication is output for each of the one or more sets of the overclocked memory settings. One of the one or more sets of the overclocked memory settings are selected as optimized overclocked memory settings for the memory.

Abstract: Profile switching for memory overclocking is described. In accordance with the described techniques, a memory is operated according to a first memory profile. During operation of the memory according to the first memory profile, a request is received to operate the memory according to a second memory profile. Responsive to the request, operation of the memory is switched to operate according to the second memory profile without rebooting. In one or more implementations, at least one of the first memory profile or the second memory profile comprises an overclocking memory profile that configures the memory to operate in an overclocking mode. In one or more implementations, the memory is trained to operate according to the overclocking memory profile prior to operating the memory according to the first memory profile.

Abstract: Methods and apparatuses control electrical current supplied to a plurality of processing units in a multi-processor system. A plurality of current usage information corresponding to the processing units are received by a controller to determine a threshold current for each of the processing units. The controller determines a frequency reduction action and an instructions-per-cycle (IPC) reduction action for the each of the processing units based on the threshold current and regulates operations of the processing units based on the determined frequency and IPC reduction actions.

Abstract: Package lids with carveouts configured to expose lights directly connected to an internal component of a processor are described. Lid carveouts are configured to precisely align and mechanically secure a cooling device to the package lid by receiving protrusions of the cooling device via a press fit connection, while maintaining visibility of lights directly connected to processor internal components when the cooling device is connected. Lid carveouts are further configured to expose one or more connectors disposed on a processor surface that supports its internal component. When contacted by corresponding connectors of an auxiliary device, such as a light not integrated into a processor package or a cooling device, the lid carveouts enable direct connections between the package’s internal components and the auxiliary device.
