Bios for 2080ti Gaming OC

Vidati · Jan 27, 2020

Hey guys,

I have been a lurker here for a while now and recently got my Gigabyte 2080TI Gaming OC under water (G12 + Kraken X72).
Temps at idle are around 28-30c and under load around 45-50c.

I was wondering since i have a reference model if i can flash a different BIOS on it with a different power target.
currently i run the core overclocked via the OC Scanner and it gave me 90MHZ extra, in game i'm usually sitting at 1980MHZ after about 30min and the memory goes to 1000MHZ (easy as its Samsung chips) but i'm running at 800MHZ for now.

Will flashing a better bios from Galax for example gives me any more advantages in this scenario or just not even bother with it?

Thanks.

You might be better off going through the overclocking process for real, not the scanner method.

Get a few gpu benchmarks together and start getting that card loaded up and turning the dials.

The scanner way of overclocking is pretty poor. You are generally leaving a lot of room to grow on the table.

My 1080 TI only is OC'd to 1974 core with scanner, but I can go to 2088mhz core and slightly past after spending a few hours figuring out what voltages were capable of what and writing them down, then doing core/voltage locking.

Basically what I am trying to say, you are no where near any sort of limit if you are relying on an auto OC finder.

Thanks, i will give it a try.

My thought was if i cool the card better it will boost higher on its own,and it did actually. not that i'm uncomfortable doing it myself its just i thought i can let the card decide whats best for himself.

Thanks for the reply.

I'm too afraid mess with GPU voltages, I don't think GPU's ever last as long as CPU's, and I'd be devastated if my GPU breaks, it's the most expensive part

I have a 2070 with pretty restrictive options, I never thought to see the perf. difference from setting the fan to max and seeing if the BIOS pushes it harder. But I guess I don't want loud fan, oh well

nvidia will not let you set a voltage that is too high for the standard cards.

gpu overclocking is all about trial and error.

There is no direct result-based guide.

I like to leave card at default everything, max out the fan speed, and run a bench. The resulting core clock and voltage gets written down, then I max the temp and power limits, lock the votlage, and start overclocking, locking the clock at each test.

This is the only way I was able to achieve beyond 2088mhz for my 1080 Ti, and I am NOT water cooled on the gpu.

You will almost always run into a temp or power limit before anything else on the 10 and 20 series of nvidia cards.

Your best bet is to set card to default, max out the power and temp targets/limits, and run a bunch of benchmarks to heat the card up.

Note the voltage it eventually gets to, lock it in the OC curve of msi afterburner, and start slowly turning the clock up.

You will eventually find yourself either hitting the power limit of the card, or start hitting the 55-60*C mark, where the card starts to get stubborn with clocks.

Flashing another card's vBIOS can help raise the voltage but Nvidia has many tricks up their sleeves with Turing. The mass majority of the high end 2080 TI's won't go above 1.1v. So, no matter which vBIOS you choose, you may end up with the same voltage limit. The good news, it is extremely difficult and rare to kill a 2080 TI with stock vBIOS. A watercooled 2080 TI should be hitting 2050 to 2075. If your card has samsung VRAM, it should easily be overclockable +1100 to 1200.
