Abstract:
A heat sink surface mounts to a printed circuit board in direct separation, thermal and physical, from components on the board. The heat sink cools the components by conducting heat from the components through the printed circuit board to the heat sink.
Abstract:
A double-high memory system compatible with termination schemes for single-high memory systems. The system includes an interface for input and output of data. A plurality of memory units is configured in two rows. A transmission line couples the plurality of memory units and the interface. The double-high memory system is provided in a non-stacked arrangement.
Abstract:
A computer system uses power-consumption monitors for each of plural sets of devices. A power budget arbiter determines whether a collective power-consumption criterion is met at least in part as a function of said power-consumption data.
Abstract:
An interface module for interfacing an external device with a host computer is physically and electrically connected to the host computer. The module monitors its own power consumption and reports its power consumption to the host computer. This information can be used to determine the total power consumed by multiple modules, to indicate a problem with the interface module, or to detect a leakage current associated with the external device when main power is off.
Abstract:
A method for changing computer system memory density. It is determined whether a memory unit is scalable to provide a first memory density and a second memory density. Information is received authorizing a change in the memory density. The firmware is updated to indicate the change in memory density.
Abstract:
A memory module includes memory devices and a power tracker for monitoring power consumption by the memory devices. The power tracker generates digital power consumption data that can be stored and used to anticipate and/or diagnose of power-related problems. The invention allows accurate monitoring of conditions that could otherwise lead to failure and provides a source of diagnostic data in the event of system failure related to excessive power consumption. Modules that self-monitor power consumption can provide highly accurate data to the user and/or the system, which has significant advantages over error-prone theoretical measurements or estimations.
Abstract:
A present invention termination stub system is disclosed. In one embodiment the termination stub system includes a first resistor, a division point, and a second resistor. The first resistor dampens reflections of a signal and is in series with an input signal path. The division point is coupled to the first resistor. The division point divides the signal into a plurality of output communication paths. The second resistor balances resistance of the termination stub system with a characteristic impedance of the signal input path. The second resistor is coupled to the first resistor in parallel with the input signal path and the plurality of output communication paths.
Abstract:
Hiding logical processors from an operating system (OS) of a computer is described. In an example, a method of hiding at least one logical processor in a computer having a plurality of logical processors includes: initializing the plurality of logical processors by executing a pre-boot routine in system firmware; identifying at least one logical processor of the plurality of logical processors to be hidden from an operating system (OS) of the computer to provide at least one hidden logical processor and at least one visible logical processor; placing each of the at least one hidden logical processor into a system management mode (SMM) by executing a park routine in the system firmware; and booting the OS of the computer to use the at least one visible logical processor.

Abstract:
A method for producing a DIMM having a reduced memory capacity. The method includes determining an amount by which a memory capacity of a DIMM can be reduced, and reducing the memory capacity of the DIMM in accordance with the determined amount to produce a DIMM having a reduced memory capacity which is available for use and a dormant memory capacity which is not available for use. A DIMM produced in accordance with the method. A computer assembly having a computer, and a DIMM disposed in the computer and having reduced memory capacity.
