Duplicating memory content with chipset attached memory is described. In accordance with the described techniques, contents of a system memory are duplicated on a chipset attached memory over a chipset link. Memory requests are serviced using the contents of the system memory and the contents on the chipset attached memory. Servicing the memory requests includes servicing a first portion of a read request using the contents of the system memory and a second, remaining portion of the read request using the contents on the chipset attached memory. Servicing the memory requests further includes communicating a write request to the system memory and to the chipset attached memory.

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.

Physical adjustment to system memory with chipset attached memory is described. In accordance with the described techniques, an indication for making one or more physical adjustments to system memory of a device is received. Contents of the system memory are transferred via a chipset link to a chipset attached memory. The device is operated using the contents from the chipset attached memory while the one or more physical adjustments are made to adjust the system memory. After the one or more physical adjustments, the contents are transferred back from the chipset attached memory to the adjusted system memory via the chipset link.

Random access memory (RAM) is attached to an input/output (I/O) controller of a chipset (e.g., on a motherboard). This chipset attached RAM is optionally used as part of a tiered storage solution with other tiers including, for example, nonvolatile memory (e.g., a solid state drive (SSD)) or a hard disk drive. The chipset attached RAM is separate from the system memory, allowing the chipset attached RAM to be used to speed up access to frequently used data stored in the tiered storage solution without reducing the amount of system memory available to an operating system running on the one or more processing units.

The disclosed method includes detecting a stalled memory request, for a first level cache within a cache hierarchy of a processor, that includes an outstanding memory request associated with a second level cache within the cache hierarchy that is higher than the first level cache. The method further includes indicating, to the second level cache, that the first level cache is experiencing a starvation issue due to stalled memory requests to enable the second level cache to perform starvation-remediation actions. Various other methods, systems, and computer-readable media are also disclosed.

A system and method for updating power supply voltages due to variations from aging are described. A functional unit includes a power supply monitor capable of measuring power supply variations in a region of the functional unit. An age counter measures an age of the functional unit. A control unit notifies the power supply monitor to measure an operating voltage reference. When the control unit receives a measured operating voltage reference, the control unit determines an updated age of the region different from the current age based on the measured operating voltage reference. The control unit updates the age counter with the corresponding age, which is younger than the previous age in some cases due to the region not experiencing predicted stress and aging. The control unit is capable of determining a voltage adjustment for the operating voltage reference based on an age indicated by the age counter.

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.
