BIOS Settings That Unlock Performance in OMEN Desktops

In this guide, we’ll show you exactly how to optimise your gaming PC for performance. We’ll explain how to enter HP OMEN BIOS, what to change (and why it matters for gaming), and how to stay safe whilst doing it.

But keep in mind: BIOS settings are powerful. Make one change at a time and always test stability. Always maintain a path back to defaults in case things don’t go as planned.

How to Access BIOS on HP OMEN Desktops

Getting into HP OMEN BIOS is straightforward once you know the right key sequence:

The HP OMEN BIOS key is typically ESC, so press it repeatedly as soon as you power on. From the Startup Menu, tap F10 to open BIOS Setup.

Alternatively, you can reach BIOS from Windows 11:

Go to: Settings → System → Recovery → Advanced Startup → Restart Now → Troubleshoot → Advanced Options → UEFI Firmware Settings.

If the system boots too quickly to catch the ESC key, we recommend disabling Windows Fast Startup. This slows down POST just enough to give you a bigger window.

Important tip: Before making any changes, write down your current settings or save a BIOS profile. That way, you can restore defaults if something doesn’t work out. It may not seem exciting, but trust us, this could prove crucial.

Essential BIOS Settings for Gaming Performance

Memory and CPU Optimisation

We recommend enabling your RAM’s XMP (Intel) or EXPO (AMD) profile. This tells your desktop to run memory at its advertised frequency. It’ll reduce latency and often provide a noticeable boost in games that are memory sensitive.

Otherwise, your system defaults to safe but slower memory speeds.

Next, verify that your CPU’s auto-boosting technology is enabled:

• On Intel machines: Turbo Boost
• On AMD systems: Precision Boost

Both features allow the processor to raise its clock speed dynamically under load—no manual overclocking required.

Also, leave Hyper-Threading (Intel) or SMT (AMD) turned on. This setting allows the CPU to handle more simultaneous tasks. It’s ideal if you’re streaming, recording gameplay, or running background apps whilst gaming.

Graphics and Display Settings

Your GPU is the centrepiece of gaming performance, and BIOS settings can ensure it runs at full potential.

First, confirm that the PCIe slot configuration is set to the highest generation your GPU and motherboard support (Gen 3, Gen 4, or newer). This ensures the card has the bandwidth it needs.

If you’re using a discrete graphics card, disable the integrated graphics option in BIOS. Whilst this won’t boost FPS by itself, it reduces overhead and ensures the system always prioritises your dedicated GPU.

On AMD-based OMEN systems, enabling Smart Access Memory (SAM)—the BIOS toggle for Resizable BAR—lets the CPU access the GPU’s entire memory buffer. In supported titles, this can deliver smoother frame rates, often a few percentage points higher. Intel and NVIDIA platforms may also support Resizable BAR, so check if your setup allows it.

If it does, enable it.

Power Management Settings

Performance also depends on how your system manages power and cooling. Raw speed isn’t the only factor.

In BIOS, select a high-performance power profile if available, which prioritises speed over energy savings.

For Intel CPUs, you may find adjustable power limits (PL1/PL2). Raising these values lets the processor hold its boost frequencies longer, but only if your cooling solution can keep temperatures in check. AMD systems offer similar headroom through Precision Boost Overdrive.

Take advantage of fan curve controls. Setting fans to ramp up earlier under load keeps thermals under control. This prevents the CPU or GPU from throttling mid-game.

Whilst it may increase noise, most gamers accept the trade-off for more consistent performance.

OMEN-Specific Performance Features

Intel-Based OMEN Systems

Intel Turbo Boost Technology: Confirm it’s enabled to allow higher per-core frequency scaling.

Intel Hyper-Threading: Keep active for modern AAA games and multitasking.

Intel AI Boost (on supported CPUs): Ensure drivers and HP OMEN BIOS updates are current, so the system can take advantage of AI-assisted performance features in Windows 11.

AMD-Based OMEN Systems

Precision Boost Overdrive (PBO): Allows Ryzen CPUs to exceed standard boost frequencies when thermals allow.

AMD EXPO memory profiles: The AMD counterpart to XMP. Use these for faster and more stable RAM speeds.

Smart Access Memory (SAM): Enable to allow the CPU direct access to the full GPU memory buffer, improving efficiency in compatible games.

Understanding Your OMEN Desktop Model

Different OMEN desktop models have varying thermal capacities and upgradeability. Understanding your specific model helps you make informed decisions about how aggressively to tune your BIOS settings.

Compact models benefit from conservative tweaks and enhanced airflow, whilst larger towers with advanced cooling solutions can handle more aggressive performance tuning. Always consider your system’s physical design and cooling capacity when adjusting power limits and voltages.

Advanced BIOS Tweaks for Experienced Users

Overclocking Considerations

BIOS overclocking can yield higher CPU or RAM performance. But proceed carefully:

• Raise CPU multipliers or memory frequency in small steps
• Test stability after each change with stress-test tools
• Adjust voltages conservatively—more voltage stabilises higher clocks but also increases heat and component wear

Storage and Boot Optimisation

NVMe priority: Set your NVMe SSD as the primary boot device for faster startup and load times.

AHCI mode: Use AHCI (rather than RAID) unless you’re running a RAID array.

Fast Boot: Speeds up POST, though it can make accessing BIOS more difficult.

Secure Boot: Keep enabled for system integrity without impacting gaming performance.

For additional storage solutions, explore HP’s range of storage and memory accessories.

Monitoring and Safety Guidelines

The more HP OMEN performance tweaks you make, the more important monitoring becomes.

BIOS monitoring: On boot, check CPU temps and fan speeds.

In-OS tools: Use HWInfo, CPU-Z, or Intel XTU to monitor temperatures, voltages, and clock speeds whilst gaming.

Stress tests: Run Prime95, AIDA64, or Unigine Heaven to confirm stability.

Remember: thermal headroom is your friend. If temps rise too high, scale back changes or improve cooling.

Optimising Your Gaming Setup Beyond BIOS

Whilst BIOS settings are crucial, they’re just one part of a comprehensive gaming setup. Consider pairing your optimised desktop with quality gaming monitors for the best visual experience, and complement your rig with gaming accessories like mechanical keyboards and precision mice.

Your peripherals work in concert with your system’s performance to deliver the ultimate gaming experience.

Troubleshooting Common Issues

System won’t boot after changes: Reset BIOS to defaults. Use the F10 menu option, or as a fallback, clear CMOS with the reset jumper or by removing the motherboard battery.

Crashes or instability: Revert the most recent tweak. Always adjust one variable at a time so you know what caused the issue.

Lost BIOS access: Disable Fast Startup in Windows, then retry ESC/F10 during boot.
