I flashed the bios on my 980 sc, and now the computer will not post. The flash process involved turning off the display drivers. Is there any way to restore my card? I saved my original bios before the flash.

Hopefully you have another GPU and your motherboard has more than on PCIe slot. If so, you can install the other GPU in the first PCIe slot and use that for your display while you attempt to reflash the bad GPU which you install in another PCIe slot. Before you go to all that trouble. Try resetting your BIOS to default with a cold reset. Unplug the PSU, remove the CMOS battery and hold the CMOS reset button for 15 seconds. Leave the CMOS battery out for 15 minutes. Reinstall the battery and see if the system will boot. If not, you're left with option one with trying to reflash the GPU using another GPU for the display.

Boot into "Safe mode with command prompt" and reflash the card with nvFlash for windows.

If you're cpu supports integrated graphics use the igpu to reflash the card.

Yep..If your mobo has onboard graphics, power off, pull the failed card, clear CMOS, power on and set BIOS to strictly use onboard graphics (not Auto), power off, put the failed card in, power on and flash it using onboard graphics to see what you're doing.
Or use another card in the primary slot to flash the VBIOS in the failed card in another/secondary slot..Use nvflash --list to ID the position failed card and i=1 (or i= whatever it's ID position is) so you don't end up flashing the good card.
That's how I've flashed borked cards, but with older nvflash, dunno if the command lines are the same or not in the new(er) versions.
If none of the above options are available to you, then you might be able to blind flash it or put the failed card in another PC or take it to a PC repair shop and have them do it.

Thanks a lot guys. I was near total desperation. This is my first build, so I am making some beginner mistakes.

Stuff happens but don't worry too much, it's probably not trashed, it probably just needs flashed back to the original VBIOS using one of the above methods and it'll probably be perfectly fine again.

For future reference, it would be very helpful to have more details on your hardware. Motherboard, processor etc etc...That way we can give troubleshooting advice that is more specific.

w.e.?? What bios are you flashing to? And....was it a copy of YOUR original bios file, with settings copied into it?

Was not my bios, its an overclock.net bios. Either way it works fine with my first card. Just reflashed again. Second gpu shows this in device manager ( Windows has stopped this device because it has reported problems. (Code 43 ) Should I have SLI Bridge off when flashing? hmmm...

I disable SLI and remove the bridge before I flash. Then I reboot once for each board before enabling them again.

There's no point in doing any of that. Disable the cards, flash, enable cards, reboot, done. Take the settings from the bios you get from OCN, copy it to a copy of YOUR bios file, and reflash. If you go into the 900 series bios by request page, we will ask you for a copy of YOUR bios. We ask for it, for a reason. I've flashed a couple of hundred different bios versions, on several different cards, and have never run into any issues at all....unless I tried flashing a bios from a different card. Whether the check sums are different for the different types of memory, or VRM style, I'm not sure....doesn't matter. It takes 2 mins to copy and paste settings, and all those issues go away.

Check sums change every time you make an alteration to the bios. At least, that's my experience.

Aye, they do...but are they different for the different types of memory? Is there something hidden that we don't see? I've heard that Hynix runs a higher voltage than Elpida and Samsung...but I've never seen anything in the bios for memory voltages. At least, nothing that stands out. Point is...not every card is exactly the same in terms of type of memory. It's always best practice, to flash back to your own bios file with settings copy / pasted in.

I was under the impression that Samsung/Elpida/Hynix all run at 1.6V, and Hynix becomes unstable with the slightest amount of overvoltage. This is why the kingpin cards use Samsung IC's, for example, as they will readily take extra voltage and therefore take better to overclocking. I think Samsung alos has tighter latencies.

That's contrary to what I had heard, but it's certainly possible. I never saw any proof either way. Just that it made sense, as the Hynix memory doesn't end up overclocking very well. The Elpida memory has a tendency to get warm and become unstable, so you have to keep it really cool. Seems like that's different from card to card though. Both of mine have Elpida. One will run at 2150+, the other barely touches 2050.

I have tried the solutions that you guys mentioned, but without any luck. I try to boot from the invigorated graphics, and that works, but then the gpu is not detected. How can I have the card recognized but not used to boot?

If the card isn't being detected by nvflash you're sol.

Tech support most likely won't help you because you flashed the card.

Support might help if you flashed another authorized EVGA BIOS onto the video board.

If the BIOS he borked was an official EVGA version he could be OK. If he tried flashing something from a different manufacturer like ASUS trying for higher clocks rates he's out of luck.

It would have to be an official EVGA bios for that to work. Even changing one thing for a "custom" bios deems it no longer official. From the sounds, it could be out of luck, but you may convince them to charge you to repair your card. They may not warranty your card at all if it isn't an official evga bios, and they should have a way to verify through the firmware ports on the card.

It is my understanding from various other posts and my time here ,the only time flashing the bios with ANY other bios that the card did not come with installed is not covered under warranty.(UNLESS)
The only time it would be is when EVGA supplies the bios directly to you with permission(this is why they test and brand the cards partly).
This is the danger in flashing bios without EVGA providing the bios and the OK to do so because you cant send it back without the factory bios for RMA/Warranty coverage .
