ЛЮТЫЙ АНДЕРВОЛЬТИНГ | СНИЖЕНИЕ ПОТРЕБЛЕНИЯ ЛЮБОЙ ЦЕНОЙ

Core topic

The video is a tutorial/guide on undervolting and reducing power consumption of NVIDIA graphics cards (desktop and laptops), using an approach similar to MSI Afterburner.

The author emphasizes there is no single “universal” setup, because performance and power behavior vary by GPU model and game workload.

Main methods (5 total) mentioned

1. Assess the cooling system condition

Better cooling increases your undervolting headroom and helps maintain stability.

Monitoring targets

• GPU average temperature
• GPU Hotspot temperature

“Bad” signs

• ~80–90°C average
• 90–100°C Hotspot
• Excessive fan noise

Practical guidance

• Avoid unnecessary forced disassembly.
• Instead, compare against existing reviews/tests for the same GPU model.

Testing methodology for comparisons Run the same load/settings used in public reviews and check:

• Temperature
• Power consumption
• Memory controller load
• Fan speed

2. Frame limiting / excess-frame management

If your monitor is 60 Hz, limiting FPS to around 60 can reduce power usage.

Ways to cap FPS

• Game settings using RivaTuner Statistics Server (installed with MSI Afterburner)
• Vertical sync

However, the author claims these can be less effective than frequency/power limiting.

Key idea FPS caps can prevent the GPU from sustaining higher clocks unnecessarily.

Example claim Using frequency/power limits can reduce consumption much more than frame limiting alone (example given for RTX 3070).

3. Reduce “standard curve” constraints via memory/core tuning

Many cards are limited by their factory boost/voltage-frequency (“standard”) curve.

Adjustments may include:

• Core frequency and voltage
• Memory frequency (not only core)

---

4. Adjust the voltage-frequency curve with stability testing

Goal: maximum power reduction with minimal performance loss.

Strategy

1. Find the minimum voltage where memory frequency does not drop.
2. If needed, raise voltage slightly until memory stays stable.
3. Then increase core frequency while maintaining the stability/power targets.

Important note about game behavior Games do not load memory equally. For example:

• One scenario may push memory usage to ~100%
• Another scenario might use memory around ~25%

So, reducing memory frequency can hurt performance in some games far more than in others.

5. Use “locking” features and iterate stability bounds

The author describes using hotkeys in the curve editor (e.g., “L” key) to lock voltage at a point so it won’t go higher.

Typical workflow

• Lock voltage (example: “Core Lock” / a field mentioned as “Korg locovset”)
• Increase core frequency
• Test stability
• If instability occurs:
  • Reset/redo the curve using the earlier chosen voltage point and max available frequency

Practical benefit Locking voltage can make stability testing faster and more convenient—though idle behavior may change.

Specific product/software details

MSI Afterburner (central tool)

• Uses the curve editor for voltage-frequency tuning.
• Mentions minimum limits in the UI (example: lower bound for frequency/voltage).

Configuration file edit (Notepad as admin)

• The author claims you can edit a configuration file to lower the minimum voltage cap (example: from 700 mV down to ~600 mV).
• This enables testing undervolt points not normally reachable in the UI.

Laptop GPU note (GTX 1050)

• Highlights NVIDIA-specific pitfalls, especially around intermediate memory frequencies and their reaction to frequency fixes.
• Suggests using intermediate memory behavior to reduce memory/core frequency with reduced performance impact—depending on the game’s memory load.

---

Key performance/power claims (as stated)

• RTX 3070 example: consumption can drop about 1.5×, and the author later suggests testing around “half” the standard values during trial.
• General claim: power may be reduced by about ~2× while losing only a couple of frames, depending on the starting point and stability results.

---

Conclusion / takeaways

• No universal undervolt preset.
• Start by verifying cooling health (temps, hotspot, noise).
• Limit frames when possible (especially for 60 Hz displays).
• Begin undervolting from the lowest voltage where memory frequency won’t drop.
• If more savings are possible, reduce memory frequency carefully based on game-specific memory load.
• Encourage users to share settings for other models.
