Bios Optimization for e-Sports.

Gaming and mouse response BIOS optimization guide for modern PC hardware.

Recommended
  • Windows 11 latest version
  • UEFI installation
  • Update drivers to latest version
  • Equipment must be compatible

BCLK:

The closest you can get this to 100.00, the better.

Memory strap (Memory Multiplier):

100:100. 100:100 should obviously provide better results since it matches BCLK. Memory with lower frequency and lower timing can reduce latency.

EIST, C-States:

Disable as many of these as possible because they bring a lot of lag cause of dynamically changing the cpu frequency.

Execute Disable Bit:

Is an Intel hardware-based security feature that can help reduce system exposure to viruses and malicious code. I just disable it.

Intel Virtualization Technology:

Disabled for any gaming PC if u dont use VirtualBox etc.

1394 Controller:

Probably 99% of people don't use it.

On-board Audio:

Enormous input lag. Should be disabled.

On-board Video:

Disable unless you use it.

HPET (High Precision Event Timer):

HPET is a hardware timer used in personal computers. Disable to lower input lag and DPC latency.

Secondary LAN:

Disable to lower DPC latency.

Hyperthreading:

For each processor core that is physically present, the operating system addresses two virtual (logical) cores and shares the workload between them when possible. Turning off hyper-threading gives more fps in CS:GO.

UEFI vs. Legacy Boot:

Legacy tends to be better with a more classic mouse movement. PC will not boot if u have installed UEFI OS or have GPT filesystem.

CPU Power Phase Control:

Extreme / Full.

CPU VRM Switching Frequency:

Manually set 500 Khz or higher.

Legacy USB Support:

Usually have to leave this enabled in order to get back into the BIOS but sometimes will have better mouse response with it off. Varies highly by motherboard.
