RTX 4070 Super Undervolt Guide: Lower Temps, Same FPS

Published

On this page

The RTX 4070 Super uses a fuller AD104 die than the plain 4070 and draws a little more power for its extra performance, which makes it an excellent undervolt candidate. A few minutes in MSI Afterburner drops its load temps, trims power draw, and quietens the fans while holding the same gaming FPS. Here’s the curve editor method tuned specifically for the 4070 Super.

RTX 4070 Super Undervolt Guide: Lower Temps, Same FPS

The 4070 Super pulls a bit more power than the base 4070, so an undervolt has slightly more headroom to claw back.

Why undervolt an RTX 4070 Super

  • Lower power draw — a stock card sits near its ~220W limit in heavy games; an undervolt pulls it comfortably under that.
  • Lower temps of several degrees, helpful for compact triple-fan models in warm cases.
  • Quieter fans as the cooler has less heat to shed.
  • Steadier boost — a cool 4070 Super holds its clock longer, keeping sustained FPS consistent.

What you need

  • MSI Afterburner with RivaTuner Statistics Server — see our MSI Afterburner guide.
  • The on-screen overlay for clock, voltage, temperature, and power.
  • A stress test and a demanding game to validate stability.

Step 1 – Open the curve editor

  1. Launch MSI Afterburner.
  2. Press Ctrl + F to open the Voltage/Frequency curve editor.
  3. Note the stock load behaviour — a 4070 Super usually boosts in the high-2700 MHz range up near 1.05–1.1V.

Step 2 – Pick a target point

The 4070 Super takes a moderate voltage cut well:

  1. Find a point between 0.950V and 0.975V on the curve.
  2. Aim to hold roughly 2750–2800 MHz at that voltage as a starting target.
  3. This is a test point, not a guarantee — the silicon lottery means each chip lands slightly differently. Start at 0.975V if you want a safer first pass, then try 0.950V.

Step 3 – Flatten the curve

  1. Click your chosen point (e.g. 0.950V) and drag it up to around 2750–2800 MHz.
  2. Hold Shift, select every point to the right of it, and drag them down so the curve flattens after your target.
  3. Click Apply (the checkmark). The card is now capped at your chosen voltage while holding a high clock.

Step 4 – Test for stability

  1. Run a stress test for 15–20 minutes, then play demanding games for 20–30 minutes.
  2. Watch for driver crashes, artifacts, or black screens — these mean the clock is too high for that voltage.
  3. If it crashes, lower the clock by 15–30 MHz (or bump the voltage point up slightly) and retest. If stable, you can try pushing the clock higher.
  4. Once stable, save the profile and enable “Apply overclocking at system startup”.

How to revert

Click the reset (circular arrow) icon in Afterburner to restore stock, or disable startup-apply and reboot. Reinstalling the drivers also clears the setting entirely.

Expected results

Expect the 4070 Super to run several degrees cooler with a clear drop in board power and fan speed, at the same FPS. The exact numbers depend on your card, cooler, and case airflow — the consistent result is cooler and quieter for identical performance.

Undervolting the RTX 4070 Super is a quick, reversible win: a flattened curve around 0.950–0.975V holds your clocks while cutting heat, power, and noise. Start at the suggested target, validate with a stress test, and save the profile once it’s stable.

Frequently asked questions

Is undervolting the RTX 4070 Super safe?

Yes. You run the card below stock voltage, never above it, so there is no risk to the hardware. If a setting is too aggressive the card simply crashes or black-screens and resets on reboot with no lasting effect.

How much can I undervolt an RTX 4070 Super?

The 4070 Super uses a fuller AD104 die than the regular 4070 and pulls more power, around 220W stock, so it has more to gain. Many samples hold their boost clock near 0.950–0.975V at roughly 2750–2800 MHz, down from a stock peak around 1.05–1.1V.

Does undervolting the RTX 4070 Super lose FPS?

No, when done correctly. You keep the same clock at lower voltage, so FPS stays equal. A cooler card holds its boost more steadily in long sessions, which can slightly raise average frame rates rather than lowering them.

What's a good undervolt for the RTX 4070 Super?

Try a flattened curve at about 0.950–0.975V targeting 2750–2800 MHz, then test. The silicon lottery means some chips will hold the top of that clock range and others need a small reduction, so treat it as a starting test point.

Will undervolting void my RTX 4070 Super warranty?

No. It is a reversible MSI Afterburner software setting that leaves no permanent change. Resetting Afterburner or reinstalling drivers returns the 4070 Super to stock behaviour.
