Introduction to AMD Ryzen™ Processor Overclocking
Chapter 3 Introduction to AMD Ryzen™
Processor Overclocking
Systems based on the AMD Ryzen processor may be tuned to deliver added system performance.
The AMD Ryzen family of processors offer an exciting amount of performance tuning options,
including potential overclocking headroom. Note that each processor and motherboard is
different, and may result in lower or no overclocking margin. Examples of processor
configurations, cores and frequencies described herein are examples only and do not necessarily
reflect commercially available products or overclocking range.
AMD Ryzen Master gives users advanced, real-time control of system performance. More details
on how to use the AMD Ryzen Master application are included in the “AMD Ryzen Master
Application” section of this guide.
The purpose of this document is to provide detailed information on the various performance
tuning knobs that are present in systems using the AMD Ryzen processor based on the AMD Zen
processor core.

AMD Ryzen™ Processor Overclocking Summary

Chapter 4 AMD Ryzen™ Processor
Overclocking Summary
AMD TR4 and AM4-based Ryzen processors are unlocked when paired with the enabling AMD
chipsets and necessary BIOS software and therefore allow the user to adjust the CPU and system
memory clocks and related parameters above or below the stock values. When run on boards
enabled for overclocking, AMD Ryzen Master will automatically enable the Overclocking Mode
at the user’s initiation of a change to a stock parameter. The CPU overclocking parameters will be
returned to stock operation through a system power cycle (Windows Shutdown, then re-starting).
System memory overclocking parameters and operation are persistent through a power cycle and
can only be changed from Ryzen Master or within the BIOS Setup.
The process for finding a stable overclocking configuration with the AMD Ryzen processor is not
fundamentally different from the previous generation AMD processors (such as the AMD FX
processors). The final operating voltages and frequencies will depend highly on the specific
system’s processor, memory, motherboard, cooling solution, operating environment, and the
user’s decisions on what elements to overclock and to what degree.
4.1 AMD Ryzen™ Processor Normal Operation
To describe how the AMD processor operates in Overclocking Mode it is best to understand how
the AMD Ryzen processor operates normally. When operating normally, the AMD Ryzen
processor has the following characteristics:
1. The frequency of processor core clock is determined by a combination of the software-
requested p-state and then adjusted by a combination of numerous power and performance
optimizing features to attain any of number of fine grain p-states around that softwarerequested p-state.
2. Internal control mechanisms measure internal temperatures, power and current consumption,
and manage the operating voltage and frequency of various internal cores to maintain specified
levels. For example, when the number of active cores is below a pre-determined threshold, the
active core temperatures are below maximum, and the consumed total current is below
infrastructure limits, then those active cores will be boosted in voltage and frequency to the cstate “boost” frequency until any of those conditions are no longer true.
3. The voltages for some of the various cores are internally generated from external supplies. For
example, each of the processor cores uses a supply independently generated from the external
supply. As the operating frequency for each processor core is adjusted to attain various fine
grain p-states, the operating voltage of the core is adjusted to support that new frequency at
optimal power consumption. The voltage adjustments are done using the internal voltage
regulator and the SVI2 controlled external supply voltage, if needed.

AMD Ryzen™ Processor Overclocking Summary
4. Software requested p-state or halt states adjust the level of power to which those internal
control mechanisms manage. For example, when software executes a HALT instruction on a
processor core, that core will enter the C1 reduced-power state. If that core does not receive
an interrupt to resume execution, it will progress to increasingly-lower power states until
finally saving the state of the core and being powered off.
5. The internal memory controller and various other data paths will be initialized to the highest
common operating frequency of any of the memory DIMMS present in the system and with
memory timing parameters obtained from the DIMM resident SPD ROMs.
A fundamental assumption of the normal operation of the AMD Ryzen processor is that the
surrounding system current delivery and cooling capabilities are designed to the specified levels.
The complicated operation described above manages the overall AMD Ryzen processor operation
to maintain those specified capabilities. But what can be done if the system provides more current
and cooling than those required for normal operation?
4.2 AMD Ryzen™ Processor Overclocking Mode
The AMD Ryzen processor supports an operating mode allowing enthusiast users to directly
control the operating condition of the processor to precisely tune the performance and power
consumption to the extent of their specific and unique system capabilities (current and cooling)
and environmental conditions (ambient temperature). This is done by allowing the user to
program or run utilities to directly set the precise voltage and frequency at which the CPU operates
so that the maximum performance can be achieved. This is called the Overclocking Mode. This
mode still uses the processor’s control methods for the external power supplies (SVI2) and
internal clock generators and divisors thereby simplifying the implementation and eliminating any
needs for voltage regulator overrides or external clock generators. This mode allows
overclocking-capable motherboards to use the same voltage regulator controllers and the same
BIOS to support normal operation and overclocking.
4.3 CPU Overclocking Enablement
When used on an overclocking-enabled motherboard, an AMD Ryzen processor is ready for
Overclocking Mode. The processor will run normally with all internal power, voltage, and
thermal management features enabled until a point in time when user-directed system software reprograms the specific voltage and frequency values to levels other than stock operating values.
The following changes take effect when the values are re-programmed and the processor enters
Overclocking Mode:
1. All enabled CPU cores operate at the newly user-programmed voltage and P0 frequency value.
Adjustment of the CPU clock is in 25MHz steps.
2. Internal features of the processor which control the CPU operating voltage and frequency to
manage the CPU temperature, current consumption, and power consumption to specified
maximums are disabled so that no additional stress to system voltage regulators and thermals
are induced. This includes c-state boost.
