Best Guide to Boost Poor Hard Drive Efficiency After System Upgrades

On Sandy Bridge and Ivy Bridge, voting rights were lost by any threads in C1e/C3/C6 states. First, when all threads went into one of these C-states on a socket, no core on that socket would have voting rights and the core frequency would drop to the minimum frequency. In Haswell, Intel introduced the Integrated Voltage Regulator .

However, it provided generally consistent performance behavior. All cores maintained voting rights even when they were in C1e/C6 states . However, a package C1e state was also used, which visit site detected certain conditions when all threads were in a C1 or deeper state and would decrease the frequency to an efficient level.

P-states are managed as a ratio of a base clock frequency . On the Nehalem generation, the bclk ran at 133 MHz. If the OS requested a ratio of 20, then the system would run at 2.66 GHz. All Xeon processors starting with Sandy Bridge have used a 100 MHz bclk. The Avoton architecture had a variable bclk that was based on the memory frequency of the system. Each different ratio is commonly referred to as a bin of frequency. It is not possible to control frequency at granularity smaller than the bclk speed.

As shown in Figure 2-8, the voltage savings from decreasing frequency shrinks at lower frequencies . Decreasing frequencies past the point of voltage scaling is possible, but it tends to be inefficient. Users are better off using C-states at this point to save power.

A module refers to a collection of cores that share resources. On Intel Atom-based server processors such as Avoton, groups of two cores share a single L2 cache. Other groupings are theoretically possible, such as sharing a single voltage/frequency domain. C-states are also possible at the module level and are commonly referred to as MCx . All cores are in CC3/CC6 and other traffic sources are also idle. Package scoped operations, such as deep memory self-refresh or uncore Vret are possible. All cores are in CC3/CC6, but PCIe or a remote socket is still active.

This enables individual cores to have their own voltage domains, enabling efficient per core P-states . Low-dropout regulators can also be used to provide variable voltages across cores in a CPU with a single input voltage, but such a technique has not been productized by Intel to date.

  • If you wish your PC’s sleep to be disturbed by nothing but Windows itself in case of an important event that is about to occur in your system, consider using the Important Wake Timers Only policy.
  • That said, you might wish your computer to keep sleeping whatever is happening around – for this, select Disable from the menu.
  • Wake timers are settings that serve to wake up your PC at a specific time – for instance, when important updates have found their way to your system and are waiting to be installed.
  • The only catch is, this setting may cause issues with some USB devices – they may fail to resume properly when you want to begin using them.

The shared uncore must still be active to support these other traffic sources. Minimal package-scoped optimizations can be performed here.

As a result, processors have a minimum supported operating frequency and may not expose lower frequencies to the operating system or allow lower frequencies to be requested. Module C-states have not been used as aggressively as core and package C-states in production on servers due to challenges in finding energy-efficient optimizations with them in server environments. These issues are similar to those observed with the flushed L3 cache in package C-states.
