What is Ryzen master?
AMD Ryzen Master. AMD Ryzen Master gives users advanced, real-time control of system performance. It also allows a user to overclock & change factory settings to make the processor operate outside of AMD’s published operating specifications. The user interface has been neatly done up.
What is PCI latency timer?
“PCI Latency Timer. Controls how long each PCI device can hold the bus before another takes over. When set to higher values, every PCI device can conduct transactions for a longer time and thus improve the effective PCI bandwidth.”
What is AMD Iommu?
IOMMU is a system specific IO mapping mechanism and can be used with most devices. IOMMU sounds like a generic name for Intel VT-d and AMD IOV. In which case I don’t think you can multiplex devices, it’s a lot like PCI passthrough before all these fancy virtualization instructions existed :).
What is dynamic tick?
Dynamic Ticks are a feature that lets windows stop the system timer when nothing is happening in order to conserve power.
What EUP 2013?
The EuP/ErP feature in our system follows ErP Lot 6 2013 compliant which requires a PC system should not consume more than 0.5 W during “off state” or “standby.” In other words, this function only works when system is shut down or in system sleep mode (S3) and the power consumption should be less than 0.5 W.
What does ErP Ready mean?
ErP/EuP (Energy Using Product) is a function to save power when the computer is in standby mode. This is a regulation so the total power of the system won’t exceed 1.0W. You need a ErP ready power supply and motherboard to have a ErP/EuP system.
What is power on ring?
From Wikipedia, the free encyclopedia. Wake-on-Ring (WOR), sometimes referred to as Wake-on-Modem (WOM), is a specification that allows supported computers and devices to “wake up” or turn on from a sleeping, hibernating or “soft off” state (e.g. ACPI state G1 or G2), and begin operation.
