01.Step 0: Entering the BIOS (The Portal)
The BIOS (now called UEFI) is your motherboard's operating system.
How to Access
- Classic Method: Restart your PC and frantically press the
DELorF2key as soon as the screen turns on. - Modern Method (If your SSD is too fast): In Windows, hold the
SHIFTkey and click Restart.
Go to Troubleshoot > Advanced Options > UEFI Firmware Settings > Restart.
Don't do it Manually.

02.1. XMP / DOCP / EXPO (RAM Memory)
This is MANDATORY setting #1.
Your RAM comes from the factory running at the slow JEDEC standard (e.g., 2133MHz or 4800MHz DDR5). XMP is the factory-tested safe overclock profile.
- Intel: Look for "XMP" (Extreme Memory Profile).
- AMD (ASUS): Called "DOCP".
- AMD (Others / DDR5): Called "EXPO".
- Action: Change from "Disabled" to "Profile 1". Save and restart.
- Benefit: Up to 20% more FPS in CPU-bound games (Warzone, Valorant).
03.2. Re-Size BAR / SAM (Smart Access Memory)
2020+ technology that allows the processor to access all the video card's VRAM at once, instead of small 256MB chunks.
How to Enable
Usually found in the "Advanced" or "PCI Subsystem Settings" tab.
1. Enable "Above 4G Decoding".
2. Enable "Re-Size BAR Support" for Auto or Enabled.
3. Requirement: RTX 3000+ or Radeon RX 6000+ GPU.
A1.3. Virtualization (SVM / VT-x)
For Emulators and Docker
If you play Free Fire on Bluestacks/LDPlayer, or program using Docker/WSL2, you NEED this.
Without hardware virtualization, emulators run at 10 FPS with stuttering.
- AMD: Look for "SVM Mode" (Secure Virtual Machine). Found in CPU Configuration.
- Intel: Look for "Intel Virtualization Technology" or "VT-x/VT-d".
A2.4. TPM 2.0 and Secure Boot (Valorant)
Valorant's Vanguard anti-cheat (and Windows 11) require these security technologies.
Secure Boot
Must be in "Windows UEFI Mode". If it's "Other OS", change it.
Note: If you change this and Windows doesn't boot, it's because your Windows was installed in Legacy (old) mode. You will need to convert the disk from MBR to GPT.
fTPM / PTT
Firmware TPM.
AMD: "AMD fTPM switch".
Intel: "Intel PTT" (Platform Trust Technology).
Fan Curve (Silence or Performance)
Q-Fan / Smart Fan
All modern BIOS have a graphical fan tool.
Configure your case fans to be off or at 20% until the CPU hits 50°C. This makes the PC silent while browsing.
Set them to ramp up quickly to 100% when it hits 75°C.
Don't do it Manually.
