CONFIGURE your PC BIOS  ▷ Step by Step Guide ▷ 2020

The BIOS is one of the most important components of your computer’s system since it this allows the processes necessary to start the operating system to run correctly. Despite its importance, many ignore that it must be properly maintained and configured in such a way that the initial functions of Windows or any other OS are considerably improved.

Configuring this component often confuses many since it does not have such an intuitive interface. In this case you will have to make use of your analysis and in a way have specific knowledge that allows you to understand everything you will see once you are inside it, so that you do not make mistakes that can make things worse instead of fixing them. However, once you know about it, setting the BIOS becomes like child’s play in school.

In this article We will teach you everything you need to know about BIOS settings so that you have the best possible boot. We will tell you everything so that at the end of the reading you are a true expert in every sense of the word. So take note and learn from the best below.

How can we access the BIOS to be able to configure it correctly?

Access the BIOS configuration panel

It is highly recommended that you learn how access BIOS before knowing how to configure it, since each manufacturer installs different versions of on their motherboards, therefore how you access it varies.

On most computers it is accessed by pressing the F12 key, just before the system starts, as well as on other computers the F2, Del keys and many others. To know for sure we suggest you consult the guide or instructions for your computer, there you can find how to enter the BIOS.

Although nowadays, many of the computers at boot show which key you should press to access the BIOS. However, even more important is the fact that you know that within this system you will not be able to use the mouse. It will be you and the keyboard against the world.

Steps to configure the BIOS of your computer and options to consider

configure your computer's BIOS

To be able to configure the BIOS to your liking, it is necessary that you know each of the functions, that is why we bring you a basic guide to most of its functions. You have to know that it all depends on the manufacturers and how they organize their options.

Each manufacturer organizes the settings differently. Although the organization that a company uses is usually almost the same, regardless of the platform. We leave you below, where are these options, for four of the most famous manufacturers in your BIOS organization.

ASUS

  • To the Tweaker: CPU and memory options.
  • Advanced: Chipset, storage and power options.
  • Monitor: System health and fan speed options.
  • Boot: Boot and security options.

ASRock

  • OC Tweaker: CPU and memory options.
  • Advanced: Chipset, storage and power options.
  • H / W monitor: System health and fan speed options.
  • Security: Security options.
  • Boot: Boot options.

Gigabyte

  • MIT– CPU, memory, system status, and fan speed options.
  • BIOS Features: Boot and security options.
  • Peripherals: Chipset and storage options.
  • Power Management: Feeding options.

M: YES

  • OC: CPU and memory options
  • Settings: Chipset, boot and security options
  • Hardware Monitor: System health and fan speed options

Now that you know this, it is time for you to know each of the functions within the BIOS and how they affect the changes you make in them.

CPU options

The first thing is the CPU options that are the ones that have the most impact on the computer startup. The most important ones are:

BCLK / Base Clock: This refers to the main system clock. A universal way to overclock the processor is provided if the motherboard supports changing this option. All of this even if you don’t have a processor that was precisely marketed for this feature, like processors Intel K #.

CPU Ratio: With this you can change the processor frequency multiplier, this only affects the cores themselves, but not the other parts of it, such as the memory controller or the integrated GPU. Changing the values ​​in the Overlock is easy, although it is only supported on the following processors.

  • Intel K or X suffix processors (for example, i5-2500K, i7-4690K, i7-5960X)
  • Intel Pentium Anniversary Edition (Pentium G3258)
  • AMD FX / Ryzen series processors (for example, FX-8350, FX-6300)
  • AMD K suffix APU (eg, A10-7850K, A8-6600K)

Spread Spectrum: This is used to propagate the electromagnetic interference (EMI) coming out of the processor through a wide range of frequencies. It does not reduce the amount of EMI, but it does it can help to focus everything on the frequency of most interest.

CPU voltage: if you are overclocking it is very useful, because higher clock speeds require voltages Taller. But keep in mind that this setting has to be used very carefully, because a relatively small change can fry your computer.

Host Clock / PCle Clock: East is used to adjust the frequency of the PCI Express controller built into the processor. Leave this feature aside unless you are altering the BCLK, or have had stability issues.

Intel SpeedStep / AMD Cool’N’Quiet: the two options set the processor clock frequency to lower frequencies. If you want your processor to run at full speed, disable it.

C-State Options: these are the processor power levels. It would be nice to keep it off when extreme overclocking is attempted to prevent the processor from changing power state.

x86 Virtualization: this helps smooth operation at near-native level. In Intel equipment it may have the name of VT-x, while on AMD computers, it can be found as AMD-V, and in old equipment they are called Vanderpool.

Memory options

Memory options have a direct impact on short-term storage (RAM), which is essential for the proper functioning of the computer after startup.

Memory Frequency: This sets the frequency of memory operation. Although you cannot choose arbitrary frequency unlike BCLK.

Timing values: allows you to directly adjust the RAM timing values. This is a short list of the most important values:

  • CAS Latency (CAS Latency).
  • RAS to CAS delay.
  • Row Precharge Time.
  • RAS Active Time.

DRAM Voltage: it is very useful if you are trying to overclock your RAM speed beyond its normal specification, although the values ​​should be handled very carefully because increasing it even a small amount can fry the RAM completely and may show physical damage.

Storage options

These are the options that directly affect the long-term storage of files. The most important to configure are the following:

SATA Mode: this protocol allows three modes:

  • SDI: This is a backward compatibility feature. It is very necessary only if the operating system does not support SATA.
  • AHCI: With this you can enable all the SATA features. If you use a modern operating system, the drives have to be left active.
  • RAID: You can configure SATA ports for motherboard onboard RAID, otherwise it acts as AHCI.

You must take great care what value it has, because if it does not have an adequate value you can damage the functioning of your PC.

Hard Disk SMART– With this, you can enable SMART features on the computer drives that support it.

Chipset / Peripherals Options

These options are more related to the operation of the equipment at a graphical level. The most important aspects to configure are the following:

Graphics Adapt and Integrated GPU (IGPU) settings: is an option used for change primary graphics adapter, which PCI Express mode you want to use, and how much memory should be allocated to the integrated GPU.

Onboard peripherals: these are options that include an integrated audio and internet adapter. You do not need to disable them when installing other software, unless your operating system has peripheral conflicts.

Legacy USB Support: With this you can make environments that do not support USB use USB devices, such as older operating systems and utilities that can be run on boot. But it is different if you have compatibility issues.

Intel and AMD Specific Features: cWith these functions you can resume hibernation and allow programs to receive updates through the internet, while the computer is idle. The name of these functions are:

  • Intel Rapid Start
  • Intel Smart Connect
  • AMD Dual Graphics

Power Options (ACPI)

As the name implies, these are the options that are related to the energy consumption of the equipment. They may seem secondary but they have the ability to limit or enhance the operation of the entire computer.

S-State configuration: These are the system level power states. The most used are:

  • S1: With this the CPU stops executing the instructions, while the memory remains on.
  • S3: Standby / Sleep / Suspend mode of RAM.
  • S4: Hibernate. RAM stores in HDD / SSD, after the system is completely shut down.
  • ErP S5: This allows the PC to consume the least amount of power possible but not complete.

State after Power Loss: When the computer loses power, the computer does the following:

  • Last State: If the PC is turned off, it will remain off, but if it was on, it will turn on again.
  • Always off (default): The computer will be off.

Among so many functions that the BIOS has, you can also find the System Health / Monitoring settings, which has some functions that have to be treated with great care or you can damage the PC for life. These functions are named:

  • Fan Speed ​​Settings.
  • Temperature Alarm Settings.
  • Case Open Feature / Reset.

The same happens with the functions that configure the startup and security of your PC, whose names are:

  • Fast / Ultra Fast Booting.
  • Num Lock on Boot.
  • Full Screen Logo.
  • Boot / POST beep.
  • Boot Order.
  • Boot / Setup Password.
  • Secure Boot.

Is it necessary to update the BIOS or UEFI for it to work properly?

update BIOS

This is one of the most common questions in society when they find out about the BIOS, and the answer is yes, since the whole system works together improving the recognition and adjustments of the hardware that is installed on the computer motherboard.

Doing this is highly recommended as time goes by, from the moment the board or equipment was purchased. For example, when you do, new instructions and compatibility are added. for hardware that did not exist at the time you purchased it since you probably want to install as an SSD drive, a more powerful processor or a certain RAM modules.

The BIOS update It consists of describing a new block of code that contains the new instructions for the computer hardware, in the non-volatile memory chip of the motherboard. With this writing of the new block of codes, it is done from outside the operating system.
