Is there a tool to edit the bios of a 2060 super (to increase power limit) card then re-flashing it with this tool? Or the only option is to try some other bios.

i flashed my 3070 ti zotac trinity to bios zotac amp extreme, but the clock still 300 in stress :(, i returned to original bios and is okay

Does anyone know why the gpu clock doesn't go up and stay at 300?
I'm glad I managed to go back to the original bios and went back to raising the clock to 1770 normally

ddu was used, I reinstalled the driver, literally everything possible and with the mod bios the clock did not go up, it just returned to normal after putting the original bios

Here's the first victim. Guys, BIOS flashing is not the solution to any problem. Your cards are fine on the factory BIOS. Live your lives and enjoy! ;)

As BIOS editing wasn't allowed after Maxwell, I guess currently there isn't any BIOS editing tool, which would work with Pascal or Turing GPUs?

Trying to flash a rtx 2070 with a rtx 2080 bios DOES NOT WORK.
Both the tools, which I presume share almost the same hack do not work.
These guys, the authors, are they Chinese?

Of course it doesn't work. This isn't what the tools are for regardless... if you want an upgrade you aren't getting one for free, sell your card and buy a newer model.

The RTX 2070 uses a TU106 chip and the 2080 uses a TU104 chip. They're completely different hardware-wise, and this wouldn't work even with the TU104 2070 Super regardless - the hardware is different. 2070S to 2080 is possible by means of bios chip replacement/force-flash + resistor mod, but is not guaranteed to work (2070S dies may be too defective). None can be upgraded to 2080S.

It's a shame they've only cracked old hardware. There are a few Quadro features that would be nice to have on current Geforces (such as Remote Desktop GPU hardware acceleration) which aren't mission-critical and there are always more cost-effective or zero-cost workarounds that make buying a Quadro just for the drivers unviable. It's just annoying that the Geforce silicon is capable of useful consumer things that are gated behind market-segmentation asshattery via drivers.

Flashing a Quadro-equivalent bios on the second bios of a dual-bios card would be awesome. Have both drivers installed and just flip the switch and boot up in Quadro mode for the rare occasion when something you need is paywalled behind a Quadro driver.

My fault, I was sure the 2070 was using the same die as the 2080.

I think the Super versions are using the next tier dies, 2060 super = 2070 , 2070 super = 2080 and so on.

Edit: - and not all are the same.

There are subrevisions yes, and notably also the TU104-based 2060 from EVGA (KO)

I thought yo could always crossflash with I think it's called nvflash from nvidia. When I had the pny 4070 ti oc I went through all the bios tech power up had, and picked the one that had the highest tdp and clocks. When I asked a couple people about it they didn't tell me you couldn't, they just advised against it if I didn't have duel bios or if I didn't know what I was doing. The I think it was gamer meld video that brought me to this post made it sound like there are two tools. One to mod bios up thru 200 series and a dif tool to allow crossflash thru the 4000 series. It and the article made sure to mention how the tools have been scrubbed and have no viruses. The best I can tell, there are no links to dl. I haven't looked for it yet but what if I find it from a place that added malware to it. Maybe I missed it but tpu should have a dl link. I now have a pny 4080 oc and a while back looked through the dif bios on this site. I found one I want to use but haven't gotten around to it yet. I would def like to use a bios with an optional higher tdp. Do I need to find this tool or can I use nvflash?

These tools are nvflash, just patched to remove some of the restrictions on flashing that nvidia imposes. I advise against flashing your 4080 with a higher power BIOS.

So if I were to take another 4080 bios and put it in my card, what was nvidia stopping exactly when the other bios is already nvidia approved? I seems like this is a better option for the 2000 series where you can change existing settings. For crossflash though, I don't understand what is dif with the patched tool. Also, Why exactly do you recommend against it. I've been using and working on computers for like 20 years but I've never dealt with discreet graphics cards since win 98 until now. I am new to them. All I know now is that when I had the 70 it could run at 3000mhz no problem. I got about 90-100 fps at 4k and the highest settings. The 80 only runs around 2500 and gets about 110fps maxed out. I would think the clock should be able to run at even more than the 70. However, the other bios I found only had about 150 more mhz. It did have a much higher tdp and I thought with more power I could push it more. This card has a beast of a cooler on it. It's damn near like the 90. It's 4 bays in my case. I'd really appr your answers and insight here. Like I said graphics cards is something I've only recently gotten into.

There's no need to do that, Ada cards are super optimized. You're unlikely to gain anything from flashing another card's BIOS onto your 4080.

Even if the tdp goes from a limit of 320 to 450? That's a rather large amount of possible added power. What is different about the patched version if you could already do a crossflash before? With the 4000 series capable one. I understand the difference that the other one can do with the 2000 series.

I guess you don't understand the technical side of it either. You could've just said that. Instead, you took the time to say the same thing three times. You could've just as easily answered the questions given you had the answers. Thx

Well, does your PNY card have the cooling and circuitry to handle 450W of power? BIOSes aren't something you flash willy nilly, especially if you're trying to crossflash from a card that has overengineered power delivery systems and advanced power control ICs.

The 450W BIOS you're referring to is from the ASUS ROG card, right? I've got one, it's essentially a 4080 on a 4090 PCB and cooling assembly, and it's so large that it makes my E-ATX motherboard look small. I dunno. Even then, it wasn't necessary to even touch the power limiter so far.

I'm not happy w/my 4090's tendency to throw Vrel perfcaps constantly. As it is it never boosts past 2745Mhz. and rarely even runs at 2745Mhz. because it's always throwing Vrel perfcaps, even though the temps are relatively low.
