Power Limit????

[Codyium]

I only use msi afterburner for temperature monitoring only.

I have NOT attempted to overclock my new card yet, but it says under power limit that I have hit the limit and bounces from 1 to 0 and back and I don't understand why?

 

hardware

Ryzen 5 2600

Fractal Design Celsius s36 AIO 

x470 Aorus gaming WIFI 5

Kingston hyperx fury black 4x4 (16gb)

FE RTX 2080

crucial p1 500gb NVMe m.2

Toshiba 7200 rpm hdd

EVGA supernova 750 G3

It means the GPU is hitting the TDP limit. If thermals are fine, then all this will be doing is prevent the GPU from turboing faster. You can increase the power limit if you want, but you may hit another performance cap called VRel, which I believe needs a GPU BIOS modification to break past.

 

Either way, if your turbo clocks are above what the box advertised and thermals are fine, I wouldn't worry about it

Ok it confused me because my 1070 never hit power limit even when I had them in sli

 

[Codyium]

could there be another reason for it doing that

No. That's the only reason for it to trigger the power limit flag.

I'm not really understanding why 2 1070s in sli never hit power limit but a single  2080 keeps hitting it.

Is it bad that it keeps hitting the power limit and fluctuate between 1 and 0 alot.

The hottest the gpu got was 51°C

And the cpu 25°C

Many programs don't utilize multiple gpus as well. What are you using to stress the cards?

Hitting the power limit and the fluctuations are normal.

When I really use the card when I play my games( tarkov, seige, KSP and BF5) and the only other thing I use is discord

It's unlikely for any of those programs to reliably push two 1070's to their power limits. You should have better luck doing so with a synthetic stress test like Unigine Heaven. 

[BHJohnson]

I never hit power limit on Heaven. I get to 1093 mV on my 1080 before I hit anything, but that's at least partly because it takes me a fair bit of voltage to get stable. Try running the 1070's with a stress test like FurMark and you'll get there.

 

Also, hitting power limit has nothing to do with the card, per se, other than how it responds to specific loads. That power limit is just a measure of the voltage drop from some resistors on the power delivery system that tells it how much current it's drawing. That voltage is converted to digital and compared against a value in the VBIOS to yield a % relative to max. That max power can be adjusted to a degree with Afterburner or similar, or can be basically ignored using a hardware mod like shunting those resistors out completely, or can be bypassed with firmware using a BIOS that supports unlimited power draw via either custom flashing or a card similar to a Kingpin card that's made for LN2 overclocking.

[Mira Yurizaki]

Also something to point out, the limit is part of the GPU's performance cap reasons, or why the card is not clocking faster. Hitting any of these is not necessarily an indication of something wrong with the card. You're going to hit a performance cap for some reason or another.

 

It's more of a question of whether or not your set up is performing as well as you want it to. If it's hitting the frame rates you want out of your system, then strictly speaking it's performing to how you want it to.

Pretty common thing to hit power limit in a lot of cards. Don’t see the issue with worrying about it. Raise power limit or don’t. Still can hit it regardless. 

[Codyium]

Update the 2080 only seems to hit power limit on seige
