If you're doing something like this, make sure you know how to reverse it. This is very dangerous if you do not know what you're doing and can leave you with a non-functioning graphics card. Back up your BIOS with GPU-Z, your screen will flash.

More specifically, what do you get black screens during? Web browsing? Gaming? Sitting at the desktop? The newest nVidia driver 352.86 crashes when web browsing.

At this point if you get blackscreens with all the BIOS, I would probably try warranty service. But you have to flash the original BIOS back on or you won't get any service. That's why I told you to back up the original BIOS first.

Hi, flexy.
 
I have the GTX 970 SC ATX 2.0
 
I have encountered the same issues as you, been testing on my own, and fooling around with those BIOS you posted.
 
 
I can't PM you here yet apparently, but i'm gonna take an educated guess that you have a steam account. If you could add me, I think we could have an interesting chat.
 
If you google search "steam ilsenz" I am the very first link that appears, or if you search 'ilsenz' in the steam client my profile is a fat smiling guy in a red shirt!
 
Cheers!

Hey flexy, I wanted to use your values for my own bios (couldn't just flash it with your bios, even though it's the same card), and I transferred over all the values, except in my bios there are an extra 11 CLK values after where your CLK ends.
It goes up to CLK 74 in mine instead of the CLK 63 in yours.
Any idea what to do with the rest of these?
My ASIC quality is 69.4% and would boost up to CLK 63, so it doesn't go any further than your edits, but I'm not sure if I need to edit the rest to some mV value or if I can just leave them at default.

yes, set those all to 1600 (max slider) so they don't get used. Your max tested stable clock should be in CLK63. (In your case probably even CLK62, but should work).

Nice, thank you!
I just flashed it with the 1443Mhz 1.187v settings bios and it seems to be stable in Witcher 3 intensive areas like the balcony so far, before it would black screen within 20-30 seconds with even a 40Mhz overclock on that scene.
Wondering if I should try my luck with the 1506Mhz bios settings if this proves to be fully stable.

Hi, flexy.
 
Sorry to see you did not reply to me, I have some useful information to share I think. Not least your assertion that temperatures are a factor in this issue. I believe that is incorrect and not in keeping with my findings on the two 970's I possess.
 
It's all anecdotal, and something that'd be easier to discuss with you to substantiate/unsubstantiate each others findings.

You're a hard man to reach out to, flexy. You've been in this thread and replying since I messaged you so it's safe to say you got my posts!
 
I guess you do not want to collaborate on this. I'll leave you to your own (incorrect) assumptions.

Re: Solution For "Black Screen" Problem For GTX 970 SC ACX2.0 (-2974) 2015/06/05 08:12:17 (permalink)
Thank you for the BIOSes Flexy. I occasionally had the "display driver stopped working" and full on computer lockup and reboot in games, especially in the FFXIV Heavensward benchmark. The benchmark seemed to always either fully lock the system requiring a reset or display driver crash. Tried every single driver from Nvidia (doing DDU each install) and ran the fan speed at 100% but nothing helped. Tried the first 2 BIOS here and same problem. Tried the 3rd BIOS and boom, 15 runs of the benchmark and not a "display driver stopper working" or black screen crash. 
 
I did notice something strange with the 1506 BIOS. The card wouldn't stay at 1506 in the benchmark. It kept bouncing around from 1400 to 1506 clock speeds. With the 1443 BIOS it stayed at 1443 the whole time in the benchmark. Either way, it works now so I'm happy. Thank you!

I'm new here, but I just wanted to report back that BIOS 4 has fixed by crash to black screen on the Witcher 3 (which would happen after just a matter of minutes) with my SLI'd cards. Was artifacting on BIOS 1; crashed after 5-10mins play on BIOS 3; perfectly stable on BIOS 4 (with an aggressive fan profile).
 
So a massive thank you to flexy for the fix.
 
Having said that, I'm going to switch out my SC ACX2.0s with cards from another manufacturer. I've been a huge fan of EVGA throughout the years, but I've just had endless trouble with these cards and everything seems to be pointing towards a skimping on quality that's the cause.

DISCLAIMER: This is not an official, EVGA approved fix/BIOS. Please use at your own risk! Flashing your card's BIOS always has a small risk that something might go wrong. Be sure you know what you're doing, especially how you would "unbrick" your card should something go wrong. I can not be held responsible should anything go wrong.

 
After lots of investigation and sharing experiences with others I/we concluded that the "Black Screen, needs PC reset" problem is because of that some cards, among them GTX 970 SC ACX2.0 cannot handle the overall load/power draw. (It's not so much a matter of that an overclock is not stable since those crashes are different, in those cases the driver crashes and the system can recover).
 
I found that the black screen issue can be solved by limiting the maximum voltage the card is using at it's maximum speed.
(In fact, my SC ACX2.0 does 1506 stable, tested, at 1.187V. Since my-2974 GTX ACX 2.0 is a very average card with ASIC quality 70% I have reason to believe that the fix should work for MOST -2974 cards)
 
The 1.187V - as compared to 1.212V or 1.200V (as would be the max voltage with the original bios) draws less power, prevents black screens, reduces temps and throttling.
 
If you have the black screen problem and want to save yourself a RMA, I can help you if you are comfortable flashing BIOS and know how to do this. Of course you would flash your cards bios at your own risk. Don't flash if you would not know how to unbrick your card again should a flash go wrong! And obviously this is only for EVGA GTX 970 SC ACX2.0 -2974 cards!
 
The BIOS here have more advantages:
 
* 1506 overclock without throttling
* Power Target increased to default 196W (from the stock 170W)
* The problem with instability at lower clocks is gone. (NEVER overclock those card's (-2974 models) core clock with Afterburner. Since you cannot add voltage with Afterburner, overclocking the core with Afterburner means that the entire voltage table won't be correct which results in instability at lower clocks). With my BIOS, this problem is solved, the clocks and voltages scale properly.
* No throttling due to "Voltage Limit" since the max. 1.212V which are specified in the BIOS are never used
 
Those BIOS also work great as general BIOS for your card, whether you have the black screen problem or not. As compared to some other modded BIOS out there, boost is not disabled and the card's voltages scale properly.
 
BIOS 1) (Try this first)
1506 clock at 1.200V

 
BIOS 2)
1506 clock at 1.187V (this might only work with cards with very high ASIC, 75%+)

 
If your card has troubles with 1506, here the same with somewhat lower clocks:
 
BIOS 3)
1443 at 1.200V

 
BIOS 4)
1443 at 1.187V

 
I recommend you try BIOS 1 first and if you still have black screens under stress (Heaven Benchmark, Games etc.) try BIOS 2 which uses even less voltage at max clock.
 
Should your card be unstable (driver crashes, artifacts etc.) try the 1443 BIOSes with somewhat lower clock. Here too try the 1.200V first, if it black screens use the 1.187V BIOS. (I found the best test for black screens is Heaven Benchmark at Ultra/Extreme and have it run for at least an hour or longer).
 
Please share whether your black screen problems are solved with those BIOS!
 
 
** UPDATE May, 21 **
 
Updated BIOS with "proper" down-clocking voltage table. Ie. should the card ever need to throttle in the upper clock ranges it does now correctly decrease voltages.
 
** UPDATE May, 27 **
 
While the above and my workaround with those BIOS still works, I am at a point that I am rather certain that the black screens are from overheating components (voltage regulators) on those cards. There is an undeniable relationship between fan speed, temperatures, load on the card and the likelihood for black screens.
 
My BIOS help since less voltage means less power draw/load and lower temps, therefore they can help to prevent the black screens crashes. HOWEVER it is important that you keep your fan running as high as you can tolerate it. I found the default fan settings in the original bios NOT sufficient. You need to get Afterburner or PrecisionX and create a custom fan profile where your fans are running 45% or faster at 75C depending how loud you can tolerate. This together with my BIOS is the best way to prevent black screens. Proper cooling of the card is important!!
 
It is also likely that an aftermarket cooler like the Arctic Twin Turbo II with the included heat-sinks for VRMs should prevent the black screens. Here however you would need to find a way to attach the heat sinks of the Twin Turbo II in a way as that you can remove them again (the included thermal glue is permanent!) otherwise you would void your card's warranty.

This is how you backup your card's BIOS: Get yourself . Disable your card in Windows device manager. In GPUZ, below the Nvidia symbol is an arrow symbol. Click on the arrow. It will ask you to save your card's BIOS to a file. Save this to your computer.
 
There is also a good collection of VGA Bios for various cards and vendors on .

Hi what do you  recommend   doing if you have no knowledge of pc's and want to fix this ?Would you make a video to make it easier to fix this

Hello,
 
Thank you! I want to add some more findings I made in the meantime.
 
I am currently *strongly* believing that it is an heat-issue related to the voltage regulators on those cards.
 
I found that a higher fan speed (in my case 47%) almost always can prevent black screens. My assumption is that higher fan speed simply cools the voltage regulators better and that the stock fan curve is simply not enough. (This is why I recommend to use a tool like MSI Afterburner).
 
It's is not so much an issue about the GPU temps (the temp which Afterburner shows), but the GPU temp can give an indication about the temps of the voltage regulators. (Aka: When the GPU is getting to 77C or higher one can assume that VRMs are also getting very hot)
 
From this one could also conclude that the VRM overheating and black screen issue would be solved by
A) either getting MSI Afterburner and turn up fan (it depends how loud you can handle it, my tolerance is 47%)
or
B) install a aftermarket cooler like the Arctic Twin Turbo II which comes with heatsinks for RAMs, VRMs etc. as well and has a FAR superior cooling performance than the stock cooler.
 
My BIOS therefore helps not because it "uses less power" (as I assumed previously) but simply because using less power (like 1.187V in my case as compared to 1.200V etc.) also creates less heat. There is definitely a relationship between fan speed (temps) and the occurrence of black screens.
 
TLDR: If you're (still) having black screens, increase your fan speed! Use MSI Afterburner and make a "steeper" custom fan curve. The default fan curve of those cards is NOT sufficient to cool the VRMs, especially under stress and especially if you overclock. I can get a black screen using default fan speed in just two runs of Heaven Benchmark...but NOT with a more aggressive fan curve.



Hi can you please get back since pm you.I cant seem to see open the drop box..Do i have to see that to fix the flash the bios?

Just a quick post to say THANKS!!
 
You have fixed my graphics card. No longer black screens and even boosts higher than stock ROM, so great job!
 
I had to use the option 4 1.8 v ROM, but that's fine. I agree about the cooling profile though as mine hits the temperature limit quite easily but at 50-55% fan, it is still quiet enough and allows full boost at 1443.

If I wanted to downclock the card from 1443 to say 1343 or 1300 how would I do that?
The temps at 1443 are too high for my liking and running the fan at 70% is really annoying.
 
I'm using Bios #3.

Could please tell me how to install this rom? What tools can i use?


Use Nvidia inspector. Also go to the website he provided of how to bios flash. By the way if you want more help check out my forum post for the extra help :D
 
someone came in and told me step by step how to do it
http://forums.evga.com/GTX-980-TI-BIOSVOLTAGE-HACK-m2360712.aspx P.S. This is for the GTX 980 ti!!! So this is NOT on how to flash your card, but more of an example of what to do.

Working with GTX 970 ACX 2.0 (non-SC!!!!)(Yeah I'm not kidding)
with ASIC 62,1%
Had to clean reinstall drivers (like when the new card is installed, used DDU)
option #3 is WORKING for me stable (at least for now)
Before i found your bios i couldn't exceed 1415MHz without Throttling and/or artifacts
now I got 1443MHz stable
HUGE THANK YOU!!!

Re: Solution For "Black Screen" Problem For GTX 970 SC ACX2.0 (-2974) 2015/07/28 05:36:42 (permalink)
So i have a SC ACX2.0 -2974. Running in Asus MB maximus, I7/3770k. 1000W Evga PSU.
I get the Black screen in Witcher3 (Balcony), in subnautica ( Steam early access game, nice one) i get the crash exactly every time i  build a base.. i can provoke it by doing this in games. The black screen is a hard one, no sync, short audio loop, .. full featured crash.  I need to completely power off the sys.
Sometimes it wont recover and i m in a boot loop, the sys cant enter the graphic mode anymore. Then the only chance to reenter OS is to boot in save mode. repair and reinstall drv.  So not fun.
  I found that if i reduce the core clock to almost standard GTX970 settings,  it seems to runs stable. If i leave the card in its stock  settings, it crashes reliable at the very same situations in above mentioned games. I can run valley or heaven benchmark for hours without an issue.. i already opened an advanced rma prior of finding this thread. Anyway , I want to say thank you all for the time you invest into this problem.

Thanks  your BIOS is perfect, here the default bios when he came in tdp to 110% in games and benchmark the VDDC began to fall from 1.2 to 1.17, 1.16 1.13 .. etc, to crash the game, with your help I got let it default to 1.87 and over to 1506 (thanks to the aSIC 74) and stopped falling voltage (VDDC) now, thank you friend!
