Msi Afterburner Power Limit Unlock

[Janoc Florez]

Youwant to optimize a Radeon RX 5000 (RDNA), Radeon RX 6000 (RDNA 2) or Radeon RX 7000 (RNDA 3) with just one click? Then AMD Software: Adrenalin Edition is the right tool for you to pursue this goal.

The tidy, modern and user-friendly interface, which bundles quick access to all software functions, game statistics, and performance values, as well as driver updates in one place, also helps to optimize the graphics card.

With the key combination Alt+R, the multifunction tool can also be called up directly in games at any time. To start optimizing, call up the graphics card tool directly from the Windows 10 or Windows 11 Start menu.

The Power Limit indicates by percentage what performance level should be sent to the graphics processor. In the factory settings provided by the manufacturer, this value is usually defined as 100 percent by default.

As can be seen from this example, by lowering the power limit from 100 to 80 percent you can already save more than 14 percent energy and run your graphics card about 5 percent cooler and significantly quieter.

The performance loss is only 6.5 percent, which is usually absolutely negligible. The great advantages of a significantly more efficient graphics card easily compensate for this small penalty. The one-click optimization is worthwhile for almost everyone.

If, instead, you want even greater performance reserves from your graphics card, you can also change the power limit to positive by +10 to +30 percent, depending on the graphics card. A positive power limit of 110 to 130 percent, however, goes hand in hand with higher power consumption, heat development, and noise.

You want to optimize a GeForce RTX 2000 (Turing), GeForce RTX 3000 (Ampere) or GeForce RTX 4000 (Ada Lovelace) with just one click? Then you have to resort to a popular third-party software, MSI Afterburner.

The Power Limit specifies in percentage what power level should be sent to the graphics processor. In the factory settings provided by the manufacturer, this value is usually defined as 100 percent by default.

As can be seen from this example, by lowering the power limit from 100 to 80 percent you can already save almost 16 percent energy and run your graphics card around 5 percent cooler and significantly quieter.

The performance loss is only 4.8 percent, which is usually absolutely negligible. The great advantages of a significantly more efficient graphics card easily compensate for this small penalty. The one-click optimization is worthwhile for almost everyone.

Here, too, the following applies: If you want even greater performance reserves from your graphics card instead, you can also change the power limit +10 to +30 percent into the positive, depending on the graphics card. A positive power limit of 110 to 130 percent goes hand in hand with higher power consumption, heat generation, and noise.

His main topics are current hardware such as processors, mainboards, RAM and graphics cards, but also operating systems and application software, Linux and open source.

I would like to set another power limit then the stock 250W on the Radeon Pro VII.

But the driver (Pro or normal one) only give you Fan tuning options. After some forth and back with the AMD support i get that you want stability. So no voltage control i can accept.

All the usual GPU tools (MSI Afterburner, More Power tool and others) just don't work or even recognize the card. On linux it looked like the Radeon Pro VII is missing the entries in the bios to make any tuning possible.

I think i would need a new Bios for the card (with the tuning features enabled) and a driver that can access them.

I don't know if anybody can help me. But with the power prices in Germany currently at 40c per kwh i need to do something.

Best outcome would be i get a driver where i can power limit the card down from 250W to 125W. I am pretty sure i can be done, even if i need to flash a bios on that card.

How could i convince the AMD support to make this for me?

I am running Milkyway@home. A distributed computing project which uses the Boinc client.

Milkyway@home is doing N-body simulations for star movements in our galaxy.

I wouldn't ask for a power limitter if the power prices in Germany weren't insanely high. We are the country with the most expensive electricity at the moment i think.

For now the GPU itself runs at 180 to 190W. Adding roughly 20% of Conversion losses and other devices on the GPU to it, that gives me around 216 to 228W Power draw.

If i could cut that down a lot by only loosing some performance that would be nice.

The Normal Radeon VII can do 80% Performance at half the power draw, which i find impressive. But it lacks the FP64 performance.

Do you have any information how this feature is implemented, or what is missing on the Pro cards?

In Linux, it is possible to use rocm-smi program, e.g., version 4.0.0. You don't have to install full ROCm, this is just a python script to edit some configuration. Alternatively, you can do it manually in /sys filesystem (you can list the available states by just reading the said files). Here is what I suggest; you have to be root for all this:

Unfortunately, it is not possible to do undervolting or overclocking. This was possible, e.g., for Vega Frontier Edition (a kind of "Pro" card) by editing the binary file pp_table (quite a tricky stuff; the undervolting is performed by tuning the socclk states), but here it doesn't work - the corresponding entries are zeroed.

In this guide, we will show you how to power limit your GPU. Using this method, your graphics card will run cooler, quieter, and more energy efficient. The method is particularly useful for owners of the latest generation NVIDIA GPUs, such as the RTX 4090 and RTX 4080.

MSI Afterburner power limiting is a form of GPU underclocking that simply allows the card to drop frequencies/voltages, thus dropping power consumption and losing a bit of performance (around 5-10% for RTX 4090).

On the main screen there is a slider called Power Limit (%), which determines the maximum power consumption of the GPU. By default the slider is set at 100%, but you can move it left or right to decrease or increase the power consumption. To perform overclocking you can move the slider to the right and increase the power limit. Respectively you can move it left to reduce the consumption.

No, using MSI Afterburner power limit is not dangerous. In general, your GPU will reduce its clock/voltage when it reaches the target limit. Whenever you make a change, you can undo it with a click of the button.

Am I the only one having issues getting the Farmer to move into Full Military power and or After burner? The Turbine RPMs reach the limit, but I don't get light indications for either, and afterburner isn't igniting when I look at the outside of the aircraft. It has been causing me grief sine, I think, the June update.

Kind of a big deal, as it makes it difficult to intercept high altitude targets, and gives a handicap in a dog fight... I can see the AI controlled planes with afterburner, but I can't seem to get my own piloted craft to reach afterburner.

It's how the real thing worked, you must push the throttles to maximum then hold down the afterburner button for a second or two. The afterburners will then light and remain lit as long as the throttles are forward of the military power gate; if the throttles are pulled back past that gate you'll need to light the afterburners manually again when pushed forward.

:thumbup: Thanks for the quick reply... I have been pulling my hair out trying to figure this out :doh: , since about the June update. I read the updates list put out by DCS, and didn't see anything about that changing in particular, and have been operating the bird the same way I have since the release of the Early Access, with slight changes, like when they inverted the incorrectly inverted switches so that they are correct...

Guess I need to go back through the manual again :joystick: (if it was added as I don't recall seeing it in the initial release of the manual) and edit my startup checklist with the engine runup tests, etc...

- I press for several seconds the military power limit button OR the afterburner enable button (both of them being next to the throttles) .. and never any military power lamps or AB lamps ever light up..

This blog uses an Nvidia graphics card, but the general idea should also work with AMD cards. The specific card here is an EVGA GeForce GTX 1060 (6 GB). Green F@H Review here: Folding on the NVidia GTX 1060

Below is the production time history plot, courtesy of I marked on the plot the actual power consumption numbers I was seeing from my computer at the wall. As you can see, reducing the power limit on the 1060 from 100% to 50% saved about 40 watts of power at the wall.

There is a downside of course, and that is in raw production. The Points Per Day plot below shows a pretty big reduction in PPD for the reduced power 1060, although it is still beating its little brother, the 1050 TI. One of the reasons PPD falls off so hard is that Stanford provides bonus points that are tied to how fast your computer can return a work unit. These points increase exponentially the faster your computer can do work. So, by slowing the card down, we not only lose on base points, but we lose on the quick return bonus as well.

Reducing the power limit on a graphics card can increase its computational energy efficiency in Folding@Home, although at the cost of raw PPD. There is probably a sweet spot for efficiency vs. performance at some power setting between 50% and 100%. This will likely be different for each graphics card. The process outlined above can be used for various power limit settings to find the best efficiency point.
