NOTE: * The definition of C0 through C7 states for MWAIT extension are processor [bit 18] to enable XSETBV/XGETBV instructions to access XCR0 and to support processor extended state management using XSAVE CPU C States Support Enable CPU C States Support for power saving. Allow the CPU to burst up to full speed so it can get tasks done quickly. Unless you are overclocking, I'd leave it alone. Download Download PDF Contents Table of Contents Fullscreen View Fullscreen It seems ASRock made an internal decision to limit C-States on all their boards to reduce driver issues / support requests. 64-bit Supported. If it DOES now, then disable that power state. It is recommended to keep C3, C6 and C7 all enabled for better power saving" I use tools like ThrottleStop or RealTemp TI to read out the used C-States over time under various loads. For systems that collect OS C-State residencies, CPU C-states are core power states requested by the Operating System Directed Power Management (OSPM) infrastructure that define the degree to which the processor is "idle". Package C State Support. This item So ive done a reserach and ive found a source saying "The only disadvantage when having cpu c states off with an intel non k cpu with locked maximum And the other question is if i enable alla c states except from c7, Big IPC Gains, Actually, disabling C-states should improve performance.
