Hello,
My 980ti's doesnt want to get more Voltage than 1.230 when i put the slider up on EVGA XOC.
While in Maxwell Bios tweaker i have it 1.275 on the Voltage table (top) and on the high CLK's.
When i use a Custom .rom made for the 980ti i get a Windows 43 hardware error.
What i would like is that the voltage on the CLK bios would be correct and the GPU itself will boost till 1544 Ghz.
Does anyone know why it wont accept the BIOS voltage?
The bios does accept the Ram ghz till 4005 like i set it to on the Bios.
Screenshots of Maxwell Bios tweaker:

Trying to increase the voltage will cause the card to code 43 due to recent changes nvidia has implemented in their drivers.

Thank you for your answer, is there any way to get more voltage through it?
Preferably not hardware related :)
Could it be an idea to get an old Nvidia driver and try again?

Yes, a older driver will allow it to work.

Thanks i will try that tomorrow.
Coincidentally that's the only thing i didn't Google :/
On the plus side, i know how most Bios's from GPU's work.

Don't have a link on it. I found out about it on the guru3d forums. 385.41 will allow it to work.

just thought it would make a good read but 1.23v is all your going to get more or less with out a bios mod anyway , right ? I'm on driver 355.82 and the slider maxed for my 980ti hybrid is the same 1.23 v [seems to run great in my opinion] stock its 1.193 ?? being a reference board maybe the factory bios set limit on these hybrids . seems even with that old a driver and a good oc stable driver 1.23 is all mine gets with out a bios mod that 5% 1.193 + 5% =1.25 the overall card power limit on the slider is 10% 250w card + 10% = 275w max [+/- ] Board power limit Target: 250.0 W Limit: 275.0 W Adj. Range: -40%, +10% just to add from a review ''Feeding more voltage to a GPU will stabilize it, but there's only so much room for voltage increases. The GPU has a hard limiter at some manufacturer-defined spec (with nVidia oversight) to reduce the chance of the GPU getting killed from overvolting. In the case of EVGA's GTX 980 Ti Hybrid, the limit seems to be approximately 1.224v; reference voltage hovers around 1.187v pre-OC in our testing'' https://www.gamersnexus.net/hwreviews/1983-evga-gtx-980-ti-hybrid-review-and-benchmarks?showall=1 would like to know if the older driver will allow that to mod if your stuck at that voltage on later drivers [from sajin'] ''1. No, any modded 980 Ti vbios will work. Max voltage you can achieve is 1.28v as your card is based off the nvidia 980 ti reference pcb. Reference pcb's are limited to 1.28v. https://forums.evga.com/GTX-980-TI-BIOSVOLTAGE-HACK-m2360712.aspx

I guess , but that was the deal with therse 900 maxwells was it not right from the get go with NVidia more restrictive on voltages / overvolting . and seems like kingpin stated this on his site https://www.kitguru.net/components/graphic-cards/anton-shilov/overclocker-overvoltaging-alone-does-not-help-maxwell-to-overclock/ ''“I would say about 95 per cent of all [Maxwell-based graphics cards] no matter [from] what [graphics card] brand, do not scale with more voltage than 1.25v-1.275v at temps warmer than 25°C or so. There is no magical BIOS that can effectively remove this.”'' cant hurt to give it a try , but if it don't shrug shoulders and move on I guess . seems I got my hybrid to 1450 all day run all programs stable at 1.23v . and that really just got the gpuz from putting lines in that perfcap reason went from a few blips at 1.193v to clear all blue with that 1.23v . so I was good on that if I ever needed to run a oc . seems the card at box stock does a good job overall all day and so far 48c been the hottest it ever got [that's even pounding it with the oc profile on ]

Hello boys, I didnt realise the conversation went on after my post. Ive ben working and tinkering on an on with the BIOS but i keep getting stuck at something: I want my card to auto boost to 1544 mhz with 1.23 V but the bios wont listen to any Voltage changes. Are the settings i can try to change in the Boost table tab that can help this? As far as i have tried, the only way to get 1.23 V is to use XOC but i dont want to load up XOC every time i want to play a game for max performance. Also, if someone has more information about the Power Table Table's: (see pictures)    Keep in mind that the value's are not standard, already edited.

1544?? that would be one heck of a luck of the draw card in a hybrid / reference board . you may get it but as far as stable in any way ? [seems only I see that at JZ the braggarts 2 bits site /what a blow hard ] and his hybrid did that out of the box stock on top of that ..lol... ya, right don't know man maybe go to kingpincooling site and read the full article on that I posted above . may get that out of a aftermarket PCB board like the kingpin or the classy [the better model numbered classy 980ti] I'm no big OC'er maybe sajin knows something better to add . he may offer a good mod bios to flash to try , but even then / luck . ''Woot ! well that was super easy! I just flashed the 980Ti-SC-MaxAir.rom and it's based off the EVGA SC bios so my card is now at 1102 core/1190 boost , I did a firestrike benchmark and my Boost went up 1493 =0 compared to 1393 before, now the temps were +4c at 55c probably because of the added voltage.'' https://forums.evga.com/Any-way-to-increase-Power-Target-on-the-980ti-m2377210.aspx that link been pointed to a lot around back when on this , maybe it got some help for ya? not that I recommend this in any way but your hybrid has the latest bios ''F0'' as old as that posts on this are maybe the first release hybris bios may of allow 1.25v instead of our 1.23 ? my card seems to work fine and as expected at stock and all I tried was a perision X over clock on its sliders and got 1450 stable all day under everything I use programs and games , but anyway I'm satisfied at out of the box stock . no point tampering with a good thig and end up back to new egg ...lol..... good luck

Disable boost to make the card run at 1544 all the time when under a load.
Tried that, didnt work because Voltage. When i put the Boost Table on 1544 (max clock) it will run to 1281. with 1709 it went to 1430 when i go over 1800 the card wont run at all because its not getting the voltage. What i'm not trying to achieve is having i BIOS that will up the Voltage but it probably won't, XOC/Afterburner it is.

maybe I'm wrong but you see you run in to this all I look at To recap, where I'm at now is: 1427 appears stable at stock 1.20v (TimeSpy, FireStrike, Heaven) 1447 is unstable at stock 1.20v 1470+ seemed ok in a quick look at 1.23v but not further tested. 1500+ instant crashes at 1.23v. Voltages are card reported. I can't set above 1.23v. Temps are great with the water cooler, has remained well under 40C under current testing loads. I just wonder how much more could I get if I mod past the 1.23v mark. Haven't tried ram yet. like him as most cant set the voltage over 1.23v ? NVidia / evga may have that as a hard limit no matter what you try to do to it ? http://www.overclockers.com/forums/showthread.php/774896-An-attempt-at-980Ti-overclocking maybe here has some help? [next pages 3 before and after +/- ] http://www.overclock.net/forum/69-nvidia/1558645-official-nvidia-gtx-980-ti-owners-club-153.html notice the cards getting more are aftermarket PCB not reference as with the hybrids then maybe as I said the old first release bios allowed some extra on the reference PCB ? I see the old post they were at 1.25 not 1.23 v as our later bios are seeming at .

There is no way to alter Voltage in the Bios that works, if it would work you would get a Win error 43 with the Nvidia drivers after 385.xx, like Gajin Said. My advise is to alter it in MSI afterburner (XOC is a MSI afterburner like skin but MSI is lighter and starts up way faster.) So you get max performance but youll have to set MSI to startup on Windows. in short, Todo: - Alter power table to always run under 100% Power limit. - Use this: and put in your own max STABLE overclock. - Dont forget to also alter the Memory clock to max STABLE overclock. - Max out the Core voltage in MSI afterburner. - IF MSI doesnt clock to max STABLE overclock, set it to it. - Set MSI to startup when starting Windows. If i forgot anything, feel free to ad or tell me where im wrong.

not bad I guess but heres mine at stock and a non K 4670 ? I don't see the gain for the efforts [opinion] , but you did achieve your goal .. [thumbs up ]   I do like your perfcap reason is nice and blue all the way .. not looking like this example

If the green line in GPU-Z is "pwr" edit your Bios so 100% = 75%.
Your Voltage isnt up to 1.23, Get MSI afterburner and give it max voltage.

looks like I don't need to do anything but let it run as is ? mine will go to 1.23 under more demanding apps . I did that to test what you said and confirmed that on my card above . thing is at stock mine does what I ask of it can I get more ? more then likely but then why ? then I noticed that some of your gpu-z readings seem ' off or funny '' ?? after 3 loops of valley and gpuz render test running at the same time [thought I had the heaven gpuz shot [sorry ]

Why overclock? Because its fun to tweak and for maximum performance. My GPU-z might look funny because its water cooled and a Custom BIOS on the card, thats why it has very low temps, fan speed etc. Again, if you want to have max FPS in games, edit your BIOS so your TDP doesnt go over 100% Then goto MSI afterburner and overclock the old way.

@Elmer.me Try this bios that I just made. All you'll need to adjust is the fan speed before running any benchmarks/games. It should run at 1544. Note: Make sure you load driver 385.41 too or you'll get the code 43 error.

Thanks for the effort mate but in order to not get driver problems with the programs i use i need to use a driver newer than that version. That is why i wanted the max performance without using the older driver and thereby best performance with "only" 1.23 V. If i ever get back to the old drivers ill give it a try, you can probably tell that with a card that does 1544 on the core and 4269.8 on the memory with 1.23V you can get way more than 1544 with more Voltage. Again, thanks for the effort, made a fix myself. :) Whenever i run into trouble ill let you know, you really seem to know your stuff.
