BIOS Settings that Unlock Performance in OMEN Desktops
Introduction
Our OMEN desktops have serious gaming power built in. But they also include the potential for even more performance through the BIOS.
With just a few setting adjustments, you can optimize CPU, memory, graphics, and power management. This delivers smoother frame rates, faster load times, and more consistent performance, a dream trifecta for gamers.
In this guide, we'll show you exactly how to optimize 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 while 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™:
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 Optimization
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
- 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 while gaming.
Graphics and Display Settings
Your GPU is the centerpiece 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. While this won't boost FPS by itself, it reduces overhead and ensures the system always prioritizes 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 prioritizes 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.
While it may increase noise, most gamers accept the tradeoff 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
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
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 stabilizes higher clocks but also increases heat and component wear
Storage and Boot Optimization
- 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
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 while 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.
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.
OMEN Desktop Model-Specific Tips
OMEN 16L
OMEN 16L features a compact form factor with limited airflow. Consider adding extra case fans (3–4×120mm) for better thermals. We recommend sticking to conservative tweaks like enabling EXPO/XMP and modest power limit adjustments.
OMEN 35L
OMEN 35L is a balanced mid-tower with room for a 240mm liquid cooler. This setup supports more aggressive CPU power limits and fan curves. Performance can remain stable even during marathon gaming sessions.
OMEN 45L
OMEN 45L is the flagship tower with HP's Cryo Chamber cooling. It's designed for enthusiasts and overclockers. It supports 360mm AIOs, multiple fans, and higher voltages without thermal throttling, ideal if you want to push PBO or advanced memory tuning.
