cross flashing different sillicon = brick

What about a different 3080 12gb bios from say Asus, etc?

 

[OneMoar]

no guarentees if your 3080 wont overclock at all then you likely just lost the sillicon lotto
more power limit isn't going to get you more voltage if you already can't hit the power limits you have....

Well it's not hitting any voltage limit or crashing, it just has not enough power

power/temp slider cranked? gpuz limit reason?

if its got a dual bios switch send it also check the thread on ocn to see if anybody has tested different rom images

Yes both maxed, it's always power limit as the reason, even when I use afterburner voltage curve and get it low to the point it won't crash. I'll check but it seems not many people have this card, 12gb 3080s were rarer and this Waterblock one even more so

 

[Konstont1n]

Would I be able to flash a better bios with this either another 3080 12gb bios or a 3080ti bios with higher power limits?

A bios from 3080 12GB will do.
From 3080ti or 3080 10gb - will not work.
Pay attention also to the presence of LHR. Bios from LHR and FHR are not compatible.

Be aware that some video outputs may stop working with another bios.

Ok! Trying a strix bios to see if there's any improvements.

Do your card have the 12PWHR or what it's called?

If so cards are limited in how many 8pins that it can connect Gamers Nexus tested this, but if you are running the 12pin directly from your PSU it's the card not the bios.

No it's an rtx 3080 using 3 8 pins pcie.
I do remember hearing that EVGA planned for 2 8 pins and one 6 pin for these cards but changed it last second but didn't fix the power delivery so they deliver power unevenly so the 3rd 8 pin under delivers and that they fixed it on the 3080 tis/3090 but I'm not sure

So if I might come back to this, I'm wondering if it's at all realistic for me to attempt to crossflash some non-OC model on my Zotac 3060Ti OC LHR? Mine is the OC model which probably adds like 1% performance (the extra clocks are so little over the standard for these I really don't even understand why the OC models exist and I really only got this one because of availability at the time.) Unfortunately, at some point I think it must have taken a bit of damage (I had followed a guide for an actual OC setting that involved a weird voltage curve where at one point it's bumped up an awful lot) and I get pixel noise from time to time (random pixels flicker random colors, increasing significantly with certain sorts of games.) Of course that's not going to go away, but I would like to try to maximize the lifetime of this card until such time as I can replace it, especially since I may give it to someone else to use until such time as it does crap out (and they aren't going to want to run overclock tools nor understand how to underclock anyway.) When I tried flashing to a different BIOS listed here even for supposedly the same model card (even the OC clocks and all) it failed even to boot though. Is there even a BIOS that would work when even that fails? Maybe a different vendor would match? It seems there must be different chips even among the same models or something I guess.

What memory vendor in your 3060ti? Samsung or Micron? Check in GPU-Z.

A lot of 3060ti were released with defective Micron memory. The main symptoms are image artifacts, games can crash, the screen goes blank up to the complete absence of a picture.
And GPU-Z may not see correct memory size (sometimes it can show 0mb).

Bios can't fix it. Only a warranty replacement of the card or soldering the memory to a working one.

Samsung.

And GPU-Z may not see correct memory size (sometimes it can show 0mb).

The memory is basically stable. No crashes or major artifacts. I get the aforementioned pixel noise that is likely caused by just a tiny bit too much overclocking causing a tiny bit of damage, but obviously not very much. I've seen this before from voltage modding specifically (I did some heavy modding to a Geforce 6800 back in the day -- including voltage.) That one did eventually die from it. I'm hoping this one has a while still in it since the particular OC was stopped as soon as I realized it was doing it and must have been only just subtly too high.

Bios can't fix it. Only a warranty replacement of the card or soldering the memory to a working one.

I never said fix it. I said make it last longer. Hoping that a non-OC version has slightly more optimal voltage tables and etc for actually holding up. In particular if it doesn't immediately die, the person I was thinking of letting have it (and to clarify before anyone says anything since misunderstanding abound, "letting have" means giving it to them along with an explanation it may die, not selling it to them -- it's a family member) if/when I can replace it isn't going to want to manually underclock it. It's well past any warranty period though regardless. Stock boost clock for this line is 1665 and these OC models run at 1695 (memory is the same on both,) so any performance difference would be hard even to measure. It may not even adjust the voltage, but I would assume that's as far as any BIOS mod could go on these unless anyone ever makes an actual BIOS editor to adjust such things (and like I said, the stock OC really isn't helping anything anyway.)

Something similar happens if you overclock the memory too much. Usually it is enough to reduce the memory frequency by 100-200-300MHz

Hoping that a non-OC version has slightly more optimal voltage tables and etc for actually holding up.....Stock boost clock for this line is 1665 and these OC models run at 1695 (memory is the same on both,)

I very much doubt that there is any difference in memory voltages between the regular and OC versions.

Videocards also have a GPU.

Hey, I've aked this in the nvflashk tool (because I've tried both tools get the same behaviour with both). I flashed my Palit 3080 with what is supposed to be a compatible BIOS from techpowerup. the backup file had the same SHA1 as the one on TPU, and the file flashed without issue. But checking the new BIOS after dumping, it didn't match the SHA1 of the file I flashed to it. I can't even get it back to stock by flashing the backup back. And this is whether I use the -6 flag or not, and regardless of which tool I use to flash. Can someone help with this please, why is this happening?

Did you try back flashing with --protectoff in the command line?
Then remove it and then use -6

Hi, I flashed the Colorful RTX 4080 16 GB BIOS GPU bios in my RTX 4080 founder edition graphics card with the NVFLASHK.EXE program.

After the bios change, the card works well, it has no problems, but it has lost the RGB lights on the GEFORCE RTX writing and the X-shaped ones in the upper part, which are no longer visible.

When I still had the standard bios I had tried to raise the frequencies with the EVGA Precision X1 program, I had exaggeratedly moved the sliders, but nothing seemed to change, even if I applied the settings.

Once I changed the bios I opened the Precision X1 program again, for the first time with the new bios, and the card immediately went haywire and the screen filled with colored squares.
I then imagined that the incorrect settings I had put had been applied to the card with the new bios and therefore I turned off the PC, disconnected the card and uninstalled the Precision uninstallation.

I then reassembled the card, turned on the PC and everything was fine, then I tried to reinstall the Precision X1 program and, as soon as I launched it, the previous scenario recurred: the card had gone haywire again

At that point I did the "cleaning" operation again and now everything is ok, but I no longer dare to launch the Precision X1 program...

What do you think could have happened?
Maybe the program saves the new parameter settings in some proprietary files and how I can to fix this ?

Greetings and thanks for your attention.

 

[zxTheWolfxz]

When uninstalling Precision X1 there should be a place to put a check mark to remove all saved settings. If that doesn't fix it just remove it.
You can also find were its install folder is and once uninstalled , go delete the folder if it is still there it may not remove the saved setting in the uninstall
by deleting the folder should remove those saved settings. Looking at my Precision X1 folder I see a folder in side named Profiles
I'm pretty sure its the one to delete if its still there once uninstalled.
If that doesn't work out get Afterburner it will have no saved setting if its the first time you have installed it.

 

[Cesare Romano]

Hi, thanks for the answer.

Is mandatory to uninstall the graphic drivers? And moreover with DDU uninstaller?

I mean, the program Precision X saves some setting modifying the files of the drivers?

 

[poppisaed]

Did you try back flashing with --protectoff in the command line?

When you say "remove it" do you mean use --protecton and then use -6 to flash? I've tried protecton and protectoff, as well as with and without -6... all same results. I can never get the new flashed BIOS's dump to match anything I flash on the card.

 

[:D:D]

@poppisaed Just check the BIOS ROM is the same by cutting at the extended ROM (InfoROM). If you use the log (-L option) nvflash should be more explicit about this.

 

[zxTheWolfxz]

@poppisaed
Sorry what I ment was to use nvflash --protectoff
Then nvflash -6 default.rom
removing it the --protectoff before trying to flash the actual vbios rom file.

@Cesare Romano​

I've never had to remove the driver. Just make sure after Precision X1 is uninstalled, to look in Program Files that the EVGA folder is gone.
If not manually delete the folder EVGA before re-installing Precision X1. That should clear all older saved settings.
I haven't actually check in this latest and last version of Precision X if the check mark place is still there since there will be no newer version.
In older versions it had the check mark place so if you was upgrading you could either keep all your old saved profiles or remove them
by placing a check mark on one of the uninstall pages. This being the last version they may not have put that option in it.

I've tried both OMGVflash and nvflashk and I keep getting the error "Image size is too large, not enough ROM space for backup image" when attempting to flash a BIOS to my Quadro RTX 5000. (The ROMs are the same 1023kb size).
All I really want to do is unlock the power and clock speed limits....

out of curiosity, what version do you have?
