Here is EVERYTHING you need to know about the new Ryzen Eco-Mode for 3rd Gen Ryzen processors!

Find out when, how and why you should enable or disable the Ryzen Eco-Mode!

Updated @ 2019-11-17 : Added a guide on enabling PBO in the BIOS, and updated the article in general.

Updated @ 2019-11-09 : Added Robert Hallock’s video on Ryzen Eco-Mode, and a compatibility list.

The New 3rd Gen AMD Ryzen Eco-Mode

AMD Ryzen Master 2.0 comes with a new Eco-Mode for 3rd Gen Ryzen processors, but NOT the Ryzen 3000-series APUs.

AMD Senior Technical Marketing Manager, Robert Hallock, gives us a quick primer in this video.

What Eco-Mode does is lower the 3rd Gen Ryzen processor’s TDP by one step :

  • 105 W and 95 W processors will be limited to 65 W
  • 65 W processors will be limited to 45 W

The 3rd Gen Ryzen processor will manage core voltage and frequency automatically to keep to the new reduced power level.

Precision Boost Overdrive (PBO), Automatic Overclocking (AOC) and manual overclocking will be disabled when Eco-Mode is enabled.

 

Impact Of Ryzen Eco-Mode

Enabling Eco-Mode naturally impacts the processor’s performance, but greatly reduces its power consumption with a significant drop in CPU temperature.

AMD shared this chart with us, comparing the performance of the new Ryzen 9 3950X, with and without Eco-Mode turned on.

With a 38% lower TDP, the AMD Ryzen 9 3950X used 44% less power and ran 7°C cooler. On the downside, it was 23% slower.

However, it offers those on a limited TDP budget the option of using a CPU with more cores than would normally be possible.

 

Ryzen Eco-Mode Use Case

According to AMD Desktop Processor Technical Marketing Manager, Don Woligroski, Eco-Mode is best used by those who want to run high-end 3rd Gen Ryzen processors in Small Form Factor (SFF) PCs, NAS, Plex boxes, etc.

It will allow them to enjoy the performance of 12 or 16 cores, without worrying about overloading the SFF power supply, or excessive heat accumulating in the small chassis.

It can also be used to trade off Ryzen processor power for more graphics card power, if there is limited power at the system level.

Since it can be applied on-the-fly, you can also use it to greatly reduce power consumption and thermal output when you are not using your high-performance Ryzen system for strenuous work.

And when you need processing power, you can instantly turn it into a high-performance gaming or content creation system with a simple switch!

 

How To Enable / Disable Ryzen Eco-Mode

Ryzen Eco-Mode will NOT appear until PBO (Precision Boost Overdrive) is enabled in the BIOS, so before you begin, check and make sure PBO has been enabled in the BIOS.

  1. Download and install AMD Ryzen Master 2.0, or newer.
  2. Select one of the four profiles to edit and use.
  3. Under Control Mode, select ECO-Mode.

  1. Click the Apply button at the bottom to activate Eco-Mode immediately.
  2. The processor will immediately manage its core voltages and frequencies to achieve the lower power target.
  3. To disable Eco-Mode, just select one of the four other control modes – Default, Precision Boost Overdrive, Auto Overclocking or Manual.

  1. Click the Apply button to disable Eco-Mode, and activate the selected control mode.

 

There Is No Eco-Mode Option In Ryzen Master!

If you do not see the Eco-Mode option in Ryzen Master, that’s because PBO (Precision Boost Overdrive) is disabled in the BIOS.

  1. Reboot your computer, and go into BIOS setup
  2. Look for the PBO (Precision Boost Overdrive) option, which may be hidden under overclocking options
  3. It will generally be set to Auto by default.
  4. Switch that to Enabled.
  5. Save the change, and reboot your computer.

After doing this, Eco-Mode will appear in Ryzen Master.
