The Best BIOS Settings for UK Gamers (2026 & Beyond)

Getting the best gaming performance isn’t just about your graphics card or processor — your BIOS settings play a huge role in how smoothly your PC runs. Whether you’re chasing higher FPS in competitive shooters or smoother gameplay in AAA titles, optimising your BIOS can give you a free performance boost with no extra hardware required.

At AWD‑IT, we build and test thousands of gaming PCs for UK gamers every year. This guide covers the best BIOS settings for gaming, explained clearly and safely — no guesswork, no unnecessary risk. Best of all, these tips are evergreen, meaning they’ll stay relevant long term.

Before You Start: Quick BIOS Safety Tips

  • Always update your BIOS from the motherboard manufacturer
  • Change one setting at a time
  • Avoid extreme overclocking unless you know what you’re doing
  • If unsure, stick to recommended values

Most modern gaming motherboards (ASUS, MSI, Gigabyte & ASRock) follow the same principles, even if menu names differ slightly.

✅ Enable XMP / EXPO (Essential for Gaming)

One of the most important BIOS settings for any gaming PC.

  • Intel: Enable XMP
  • AMD: Enable EXPO or DOCP

This allows your RAM to run at its advertised speed instead of the default, slower setting.

✅ Why it matters:

  • Increased FPS in CPU‑heavy games
  • Faster loading times
  • Improved overall system responsiveness

Tip from AWD‑IT: Many performance issues we see are simply XMP/EXPO being disabled.

Best Sim Racing Setup for Beginners: Start With the Essentials

You don’t need a full cockpit immediately. A well‑chosen beginner setup helps you develop skills faster and keeps costs under control.

1. Steering Wheel and Pedals (Top Priority)

Your wheel and pedals are the most important part of any sim racing rig. Force feedback allows you to feel grip changes, kerbs, and steering resistance—crucial for learning car control.

Beginner tip: Focus on force feedback quality rather than raw power.

✅ Enable Resize BAR / Smart Access Memory

If you’re running a modern GPU (RTX 3000/5000 or RX 6000/7000 series):

  • NVIDIA: Enable Resizable BAR
  • AMD: Enable Smart Access Memory

✅ Benefits:

  • Higher minimum FPS
  • Smoother open‑world gaming
  • Better GPU efficiency

✅ Set CPU Power Limits Correctly

Modern CPUs dynamically boost based on power and temperature.

Recommended:

  • Enable Enhanced Turbo / Precision Boost
  • Allow motherboard default power limits (not heavily restricted)

Results:

  • Higher sustained clock speeds in games
  • Better performance under load
  • No noticeable increase in everyday power usage

Avoid disabling all limits unless you have high‑end cooling.

✅ Enable Above 4G Decoding

This is a must‑enable setting for modern GPUs and pairs directly with Resizable BAR.

  • Found under PCIe / Advanced Settings
  • Required for best GPU performance

✅ Safe and recommended on all gaming PCs.

Ensure your GPU and NVMe SSDs are running at full speed

✅ Set PCIe Mode to Gen 4/5 or Auto

Ensure your GPU and NVMe SSDs are running at full speed.

  • PCIe Mode: Auto or Gen 4 (if supported)
  • Avoid forcing Gen 3 unless troubleshooting

This ensures:

  • Faster data transfer
  • Reduced bottlenecks in demanding games

✅ Disable Unnecessary Background BIOS Features

To reduce latency and system overhead:

  • Disable unused SATA controllers
  • Disable onboard RGB controllers (optional)
  • Turn off legacy compatibility options where possible

These small tweaks collectively help deliver a snappier gaming experience.

✅ Fan Curves: Balance Cooling & Noise

Modern BIOS fan control is excellent — use it.

Suggested setup:

  • Quiet curve under low load
  • Steeper curve above 70°C
  • Prioritise CPU fan response for gaming

Better thermals = better sustained performance, especially during long gaming sessions.

✅ Enable Fast Boot (Optional for Gamers)

Fast Boot reduces startup time without affecting gaming performance.

✅ Safe to enable
❌ Disable if you frequently access BIOS or dual‑boot

At AWD‑IT, stability always comes before chasing tiny benchmark gains.

❌ BIOS Settings UK Gamers Should Avoid

Some settings sound tempting but can cause instability:

  • Extreme manual overclocks
  • Disabling CPU power safeguards
  • Undervolting without testing
  • Outdated BIOS versions

How to Get the Best Gaming Performance from an iGPU

If you’re gaming on integrated graphics, a few smart choices make a big difference:

✅ Use Fast Dual‑Channel RAM

  • DDR4 3600MHz or
  • DDR5 5600MHz+

This boosts performance significantly.

✅ Up‑to‑Date Drivers

Always run the latest AMD or Intel graphics drivers.

✅ Optimise Settings

Lower shadows, textures, and post-processing for large performance gains.

Tower air coolers should pull air from the front and push it towards the rear exhaust.

5. CPU Cooling & AIO Placement

Air Coolers

Tower air coolers should pull air from the front and push it towards the rear exhaust.

Browse high‑performance air coolers:

AIO Liquid Coolers

Best placement for airflow:

  • Front‑mounted AIO → Intake
  • Top‑mounted AIO → Exhaust

AIO cooling solutions available here:

⚠️ Avoid bottom‑mounted radiators — they trap heat and restrict airflow.

 

6. Cable Management Improves Airflow

Neat cabling isn’t just cosmetic — it directly improves airflow.

✅ Route cables behind the motherboard tray
✅ Keep GPU intake fans clear
✅ Use PSU shrouds properly

Power supply upgrades with cleaner cabling:

7. Keep Your PC Clean

Even the best airflow setup fails if dust builds up.

Maintenance tips:

  • Clean dust filters every 4–6 weeks
  • Replace clogged airflow filters
  • Re‑check temperatures after cleaning

Final Verdict: Are Integrated Graphics Enough for Gaming?

Yes — absolutely, depending on what you play.

If your focus is:

  • Esports titles
  • Casual or indie games
  • Budget gaming builds
  • Silent or compact PCs

…then modern integrated graphics are more than capable.

And at AWD‑IT, that means you can build a powerful gaming PC without overspending while keeping the option open to add a GPU later.

Final Thoughts: Optimised BIOS = Better Gaming

Optimising your BIOS is one of the most overlooked upgrades for PC gaming — yet it’s completely free and can noticeably improve performance.

Whether you’re gaming at 1080p esports level or 4K ultra settings, these BIOS tweaks help your hardware deliver what it’s truly capable of.
