Abstract: System memory training with chipset attached memory is described. In accordance with the described techniques, a request is received to train a system memory of a device. Responsive to the request, contents of the system memory are transferred to a chipset attached memory. The device is operated using the contents from the chipset attached memory. While the device is being operated using the contents from the chipset attached memory, the system memory is dynamically trained. After the training is complete, the contents are transferred back from the chipset attached memory to the trained system 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: A method and apparatus for managing overclocking in a data center includes determining a frequency limit of a first processor of a first server in the data center. The voltage of the first processor is lowered to a stability point, and the frequency is lowered. The first server is tested for stability. Based upon the results of the test, the voltage and frequency modifications are deployed to a second processor of a second server in the data center.

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 for processor connection and alignment are described. Lid carveouts are configured to align and mechanically secure a cooling device to the package lid by receiving protrusions of the cooling device. Because the lid carveouts ensure precise alignment and orientation of a cooling device relative to a package lid, the lid design enables targeted cooling of discrete portions of the lid. Lid carveouts are further configured to expose one or more connectors disposed on a surface that supports package internal components. When contacted by corresponding connectors of a cooling device, the lid carveouts enable direct connections between the package and the attached cooling device. By creating a direct connection between package components and an attached cooling device, the lid carveouts enable a high-speed connection for proactive and on-demand cooling actuation.

Abstract: Task scheduling based on component margins is described. In accordance with the described techniques, a scheduler of an operating system accesses a margin table when a request to perform tasks is received. The scheduler schedules tasks on various components of a system based on margins of those components. When a request to perform a task is received, for example, the scheduler accesses the margin table and selects a component to perform the task based on the margin information included in the margin table as well as based on the task, such as whether the task benefits more from being performed fast or being performed accurately. The scheduler then schedules the task using the selected component.

Abstract: Stability testing for memory overclocking is described. In accordance with the described techniques, operation of a memory with overclocked memory settings is testing during a boot up process of a computing device. Test results based on the testing are exposed via a user interface. The test results predict a stability of the memory over a subsequent time period if the memory is configured to operate with the overclocked memory settings.

Abstract: Power management using temperature gradient information is described. In accordance with the described techniques, temperature measurements of a component are obtained from two or more sensors of the component. A temperature of a hotspot of the component is predicted based on the temperature measurements obtained from the two or more sensors of the component. Operation of the component is adjusted based on the predicted temperature of the hotspot.
