Real PC Performance Lives in Your BIOS/UEFI
Your BIOS is a goldmine of untapped performance. Manufacturers ship systems with ultra-conservative settings to ensure stability across all scenarios. But you’re not running a server farm. You’re gaming.
Time to unlock what you paid for.
Memory Optimization
Here’s a fact that’ll make you angry: If you bought DDR4-3600 or DDR5-6000 RAM, it’s probably running at 2133MHz or 4800MHz right now.
That’s leaving 40-50% performance on the table. XMP (Intel) and EXPO (AMD) profiles fix this instantly.
For ASUS boards:
- Press DEL during boot to enter BIOS
- Navigate to “AI Tweaker” or press F7 for Advanced Mode
- Find “AI Overclock Tuner” or “D.O.C.P” (AMD boards)
- Select “XMP I” or “XMP 3.0” for DDR5
- Check that DRAM Frequency now shows your kit’s rated speed
For MSI boards:
- Enter BIOS (DEL key)
- Look for “OC” menu at the top
- Find “A-XMP” or “Memory Try It!”
- Select Profile 1 or the speed matching your RAM
For Gigabyte boards:
- Enter BIOS (DEL key)
- Navigate to “M.I.T” or “Tweaker”
- Find “Extreme Memory Profile (X.M.P.)”
- Change from “Disabled” to “Profile1”
XMP/EXPO gets you 80% there. For the remaining 20%, we tune subtimings. This is where enthusiasts separate from casuals.
Primary timings to adjust:
- tCL (CAS Latency): Lower is better. Try reducing by 1 from XMP
- tRCD: Often can match tCL
- tRP: Usually same as tRCD
- tRAS: Set to tCL + tRCD + tRP + 2
- Command Rate: Try 1T if stable (2T is default)
Key secondary timings:
- tRFC: Has huge impact. Use Ryzen DRAM Calculator for guidance
- tFAW: Set to 4x tRRD_S
- tWR: Usually safe at 12-16
After any memory changes, stability testing is crucial:
- Quick check: Boot to Windows, run CPU-Z to verify speeds
- Gaming stability: Play your most demanding game for 30 minutes
- Memory test: Run HCI MemTest or OCCT for at least 1 hour
- Performance validation: Use AIDA64 memory benchmark
Expected gains from proper memory config:
- Read bandwidth: 50,000+ MB/s (DDR4-3600)
- Latency: Under 65ns (Intel), under 70ns (AMD)
- Gaming: 10-30% FPS increase in CPU-limited scenarios
Memory Voltage Safety Guide
Safe daily voltages:
- DDR4 DRAM Voltage: Up to 1.45V for Samsung B-die, 1.40V for others
- DDR5 DRAM Voltage: Up to 1.35V for most kits
- VCCIO/VCCSA (Intel): Keep under 1.25V
- SOC Voltage (AMD): 1.15V max for Ryzen 5000/7000
Higher voltages are possible but reduce component lifespan. Stay within these limits for 24/7 gaming use.
CPU Performance
Modern CPUs are held back by power limits and conservative boost behavior.
Let’s fix that without traditional overclocking risks.
Essential BIOS changes:
- Power Limits: Set PL1 and PL2 to 253W (or “unlimited”)
- Current Limits: IccMax to 307A
- TVB Voltage Optimization: Enabled (better boost behavior)
- Ring Ratio: Set to Core Ratio minus 3
- AVX Offset: 0 for gaming (no AVX workloads)
Advanced tweaks:
- LLC (Load-Line Calibration): Level 4-5 for stability
- AC/DC Loadline: Match your LLC setting
- Disable C-states for lowest latency
Precision Boost Overdrive (PBO):
- PBO Limits: Motherboard or Manual
- PPT: 300W (or motherboard max)
- TDC: 225A
- EDC: 225A
- Scalar: 10X (maximum boost duration)
- Curve Optimizer: -10 to -30 per core
Additional tweaks:
- FCLK (Infinity Fabric): Match half your RAM speed
- Power Supply Idle Control: Typical Current
- Global C-states: Disabled for gaming
PCIe & Platform Features
Resizable BAR (AMD calls it Smart Access Memory) lets your CPU access all GPU memory at once. Here’s the complete setup process most guides miss:
- Update your motherboard BIOS to the latest version first
- Enable these in exact order:
- Above 4G Decoding: Enabled
- Re-Size BAR Support: Enabled (may be under PCIe settings)
- CSM Support: Disabled (CRITICAL – must boot in pure UEFI)
- GPU VBIOS check: Some RTX 30 series cards need a VBIOS update
- Verify in Windows: GPU-Z will show “Enabled” for Resizable BAR
Troubleshooting:
- If Windows won’t boot after disabling CSM, you may need to convert from MBR to GPT
- Some X470/B450 boards need a beta BIOS for full support
- Intel 10th gen and AMD Ryzen 3000 are minimum requirements
Games with biggest gains: Forza Horizon 5 (+12%), Assassin’s Creed Valhalla (+10%), Watch Dogs Legion (+8%)

Conclusion
PC optimization is a journey, not a destination – especially in games like Rocket League or Valorant. Every system is unique, and what works perfectly on one might need adjustment on another. Start with the fundamentals: enable XMP/EXPO, configure your BIOS properly, and ensure Windows isn’t sabotaging your performance with unnecessary security features.
The beauty of PC gaming is this level of control. Console players are stuck with what they’re given. You can transform a decent gaming experience into something exceptional through smart optimization. Whether you use automated tools like Hone or dive deep into manual tweaking, the performance gains are real and measurable.
Remember: benchmark everything, keep what works, and don’t be afraid to experiment. Your perfectly optimized gaming PC is waiting. Time to unlock it.
FAQs
What’s the single most impactful optimization for gaming performance?
Enabling XMP/EXPO in BIOS is the biggest single improvement. Most systems run RAM at 2133MHz instead of rated speeds like 3600MHz. This one change can boost gaming performance by 15-30%, especially on Ryzen systems where memory speed directly affects CPU performance.
Is it safe to disable Windows security features for gaming?
Disabling Memory Integrity (VBS) is relatively safe on a dedicated gaming PC and can improve performance by 10-15%. However, keep Windows Defender enabled and only disable VBS if you don’t store sensitive data. For dual-use PCs (work and gaming), consider creating separate user accounts with different security settings.
How do I know if my optimizations are actually working?
Use CPU-Z to verify RAM speeds, GPU-Z for graphics settings, and benchmark before/after with tools like CapFrameX or MSI Afterburner. Look for improvements in 1% low FPS (smoothness) not just average FPS. Real validation comes from actual gameplay: reduced stutters, lower input lag, and consistent frame delivery.
Will optimization tools like Hone void my warranty?
Software optimizations don’t void hardware warranties. Hone and similar tools only modify Windows settings and configurations, not hardware. However, BIOS modifications like overclocking or extreme power limit changes could affect warranty. Stick to XMP/EXPO and standard BIOS optimizations for warranty safety.
Do these optimizations work for laptops?
Most optimizations apply to laptops with some differences: XMP/EXPO may not be available, BIOS options are limited, and thermal management is crucial. Focus on Windows optimizations, GPU control panel settings, and use tools like ThrottleStop to manage power limits. Always monitor temperatures closely on laptops.
How often should I update GPU drivers for gaming?
Update GPU drivers for new game releases or if experiencing issues. Otherwise, if your system is stable, updating every 2-3 months is sufficient. Always download directly from NVIDIA/AMD, not Windows Update. Keep your current driver installer as backup in case new drivers cause problems.
Can optimizations fix stuttering in games?
Yes, many stutters are caused by fixable issues: slow RAM (fix with XMP/EXPO), CPU power management (disable core parking), background Windows services (disable Sysmain), or shader compilation (increase shader cache size). Tools like LatencyMon can identify specific stutter causes. Most stuttering issues can be resolved through proper optimization.
What’s the difference between game mode and ultimate performance power plan?
Game Mode manages background tasks and notifications during gaming, while Ultimate Performance power plan keeps your CPU at maximum readiness by eliminating power-saving delays. Use both: Ultimate Performance ensures hardware runs at full speed, Game Mode ensures Windows doesn’t interrupt. They complement each other for best results.
