Our OMEN desktops deliver substantial gaming power straight from the box. Yet they also harbour potential for even greater performance through the BIOS. With just a handful of setting adjustments, you can optimise 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 precisely how to optimise your gaming desktop 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:
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, this is Turbo Boost. For AMD systems, it’s 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. This feature dynamically increases clock speeds when demanding applications are running, delivering the extra performance you need during intense gaming sessions.
Intel Hyper-Threading: Keep active for modern AAA games and multitasking. This technology allows each physical core to handle two threads simultaneously, improving performance in games that can utilise multiple threads effectively.
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. This can optimise resource allocation and improve responsiveness during gameplay.
AMD-Based OMEN Systems
Precision Boost Overdrive (PBO): Allows Ryzen CPUs to exceed standard boost frequencies when thermals allow. This technology intelligently monitors temperature and power delivery to push performance beyond base specifications safely.
AMD EXPO memory profiles: The AMD counterpart to XMP. Use these for faster and more stable RAM speeds. EXPO profiles are specifically optimised for AMD platforms and can deliver better performance than standard JEDEC timings.
Smart Access Memory (SAM): Enable to allow the CPU direct access to the full GPU memory buffer, improving efficiency in compatible games. This feature can provide noticeable performance improvements in memory-intensive titles and higher resolutions.
Advanced BIOS Tweaks for Experienced Users
Overclocking Considerations
BIOS overclocking can yield higher CPU or RAM performance. But proceed carefully with these steps:
- 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
If you’re looking to complement your OMEN desktop setup with high-performance peripherals, consider pairing your optimised system with quality gaming accessories.
Storage and Boot Optimisation
NVMe priority: Set your NVMe SSD as the primary boot device for faster startup and load times. Modern NVMe drives can significantly reduce Windows boot times and game loading screens compared to SATA SSDs or mechanical hard drives.
AHCI mode: Use AHCI (rather than RAID) unless you’re running a RAID array. AHCI provides better performance and functionality for single-drive configurations, including support for native command queuing and hot-swapping.
Fast Boot: Speeds up POST, though it can make accessing BIOS more difficult. This option skips certain hardware checks during startup, reducing boot time by several seconds. If you need frequent BIOS access, consider leaving this disabled.
Secure Boot: Keep enabled for system integrity without impacting gaming performance. This security feature prevents unauthorised operating systems and malware from loading during startup, providing an additional layer of protection without performance penalties.
Monitoring and Safety Guidelines
The more HP OMEN performance tweaks you make, the more important monitoring becomes. Proper monitoring helps you identify potential issues before they cause system instability or hardware damage.
BIOS monitoring: On boot, check CPU temps and fan speeds. Most modern BIOS implementations display real-time temperature and fan speed information, allowing you to verify that cooling is functioning properly before entering Windows.
In-OS tools: Use HWInfo, CPU-Z, or Intel XTU to monitor temperatures, voltages, and clock speeds whilst gaming. These applications provide detailed real-time data about system performance and can help you identify thermal throttling or power delivery issues.
Stress tests: Run Prime95, AIDA64, or Unigine Heaven to confirm stability. These applications push your system to its limits, revealing instability that might not appear during normal use. Always run stress tests after making BIOS changes to ensure system reliability.
Remember: thermal headroom is your friend. If temps rise too high, scale back changes or improve cooling. Most CPUs are designed to throttle performance when they reach thermal limits, so maintaining good temperatures ensures consistent performance.
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. Most motherboards also have a dedicated clear CMOS button on the rear I/O panel.
Crashes or instability: Revert the most recent tweak. Always adjust one variable at a time so you know what caused the issue. If you’re unsure which change caused instability, reset to defaults and reapply changes one at a time, testing after each adjustment.
Lost BIOS access: Disable Fast Startup in Windows, then retry ESC/F10 during boot. Fast Startup can interfere with keyboard input during POST, making it difficult to enter BIOS. Disabling this feature in Windows power settings resolves the issue.
If you’re experiencing persistent issues with your gaming setup, ensure your gaming accessories and peripherals are properly configured and compatible with your BIOS settings.
