Method, systems and apparatuses may provide for technology that executes a margin test of a first memory storage based on a subset of first signals associated with the first memory storage. The technology determines, based on the margin test, first margin data to indicate whether the first memory storage complies with one or more electrical constraints. The technology determines, based on the first margin data, whether to execute a signal training process.

Selective margin testing to determine whether to signal train a memory system

An embodiment of a semiconductor apparatus may include technology to determine if a threshold is met based on runtime memory usage, and enable foreground memory deduplication if the threshold is determined to be met. Other embodiments are disclosed and claimed.

Dynamic memory deduplication to increase effective memory capacity

An embodiment of a semiconductor package apparatus may include technology to identify a partial set of populated memory channels from a full set of populated memory channels of a multi-channel memory system, and complete a first boot of an operating system with only the identified partial set of memory channels of the multi-channel memory system. Other embodiments are disclosed and claimed.

First boot with one memory channel

A method includes modifying a basic input/output system (BIOS) to load a virtual general purpose input/output (GPIO) driver in an operating system, the virtual GPIO driver comprising at least one control method to monitor a system control interrupt (SCI) (). The method can also include detecting the system control interrupt invoking the virtual GPIO driver () and executing the control method corresponding to the system control interrupt, the control method to be identified in the modified BIOS (). Furthermore, the method can include detecting an error from the execution of the control method () and modifying an operating system to prevent the error (), the modification comprising a modification to the control method.
