Gigabyte 2070 super Gaming OC 8GB power limit

[senta]

I've got a new card and I've done some benchmarks.

The thing that bothered me was that my GPU was power limited which is normal but I haven't been getting higher scores like my friend. He has the same card and he told me his power limit is 111%

In this article it is also showed since the GPU/chip is the same: Link

Could it be my mobo? Any suggestions?

Is your friends system identical in every respect?
If not, ignore the difference in FPS.

Looks like Gigabyte limited how far over 100 for the power limit slider you can go in the BIOS on the card. It’s the same for me on the MSI GeForce RTX 2060 GamingZ I have.

The power limit is set in the GPU bios, the only difference that i know of is that his card is gray/black and mine white.

Yes but for my card it should be 111% from the sources I have seen. If I am right I would just RMA it, it coil whines brand new anyway.

 

[biffzinker]

Coil whine is annoying, it’s been rare for me. One past card did that too me. This MSI card doesn’t have it.

This is both cards to prove they are the same, mine=white 106% TDP, friends=black 111% TDP

Looks like you got a dud, not that it is faulty as it works fine at 100% as it should.
There's no guarantee you will get a better one next time.
Also the power limit is +112% in the cards Bios.

So I am correct that the power limit is lower than it should be? Should I flash the bios and where can I find the bios?

Would you say that flashing a VBIOS is dangerous or as any bios? Does it void warranty?

I have never flashed a GPU bios before. Thanks you.

 

[biffzinker]

mine=white 106% TDP

My power limit is 5% over 100 for this card.

Also the Subsystem ID is not matching, is that okay?

Search through the available Bioses listed for one the same to save headaches later.

yes it does void the warranty and yes you could brick your card.
and you should think of what ya gain from it- 10mhz more or ??

you and your friend should do a comparison on gpu-z sensor page under 3d load there ya see how far yours +your friends card boosts.
i think there will not be big diff
first i would overclock your processor !


in your first screenshot i see that you put voltage to max-thats not how it works today- could even be counterproductive.
more temp means lower boost. brutal volt pushing times are over !
and if ya push gpu memory too far score gets lower

and even if ya have 2 equal systems-he could have better airflow-lower temps higher boost ,samsung versus micron memory -your cards could be revision different , room could be colder, if ya have different motherboards your cpu could be running little bit diff speed of cpu and so on

good threads on tpu which i would read first from regeneration like this:

How to increase power limit by BIOS crossflash

Since BIOS editing isn't possible since Maxwell. The alternative to increase power limit is to cross-flash to another BIOS with higher TDP. This method can also help with other BIOS-controlled features such as: minimum fan speed, fan stop feature, voltages, clock states, and more. However, there...

So quick to flash a bios! Havent you seen all the threads of people who **** it up?

At your own risk indeed. I'm not sure software will fix a hardware limitation.

Overclocking is restricted on modern graphics cards due to a power limit coded in the BIOS. You can set whatever clock frequency you want, but it will be throttle back when the power limit is reached. There are two ways around it:

1. Hard mod on the PCB.
2. Flash to a BIOS with higher limits.

The 2nd option is the easier one. And even if the card gets bricked, there are many ways to recover.

Indeed, just didn’t want to see another kid brick his card..

Nvidia cards don't brick that easily. Unlike AMD, most Nvidia BIOS ROMs support all memory brands.

Wrong BIOS flash usually bricks some of display outputs or causes poor performance in 3D modes.

I'm 25 and work in computer industry. The subject here was to collect information on a subject I don't know too well - GPU bios and to see why 2 identical cards have different power targets which is the most important OC variable in the new cards - hitting the power limit = limits performance. Voltage is also set by the bios and giving it max voltage is a % of what voltage it will use if needed. In this case it will use 1008 mV at boost and is hard capped there.

To make myself more clear I am nitpicking here. I would not use custom bios and actually use a high overclock to squeeze 2% more frames. But I believe everyone should push their card and see the results they are getting while the GPU is performing at max.

 

[freeagent]

Quality of silicon also plays a small part, not every slice is of equal quality. That goes for CPUs and GPUs alike.

 

[basco]

putting temp+power target higher i understand but if you are power limited and you push more volts then you get negative effect in getting earlier into the limit + hotter which both results in lower megahertz.

and i mean that can happen when going from like my card 1,0620volt to 1,0750v.

and by the way i love overclocking and i am not saying don't do it.
i powermod my cards with conductive silver.

and again a reminder round numbers are nice but in non of the 3 reviews i read for this card nobody did 8000mhz on the ram just little lower- on this newer cards you wont have screen artifacts but lower performance.
