Could you point out any Gigabyte G1 Gaming 980 roms for me to try out?

I currently have a custom bios pushing it to 1481MHz/7600MHz, but I am a bit scared with the power settings - I copied that from the OP's EVGA SC980's V2 rom and I am paranoid it will die on me.


This is mine

My voltage is 1.256v pulls basically pulls that too anymore, I hit a hardware limit I believe, I tried taking it to 1.29v and 1.30v, wouldn't budge above my current voltage.

Edit:

I also push another 50mhz core and 50mhz memory in afterburner after these settings.
I add 100mv from afterburner and my voltage rounds off to about 1.258v or so.

Try flashing your bios with 1.22v or something and you'll know if its a hardware limit.
I hit mine at just below 1.27v.

I am not sure I understand what you mean? How can I flash a bios with voltage? bigeyedsmiley.png

Change the power tables and make sure the top bar is your desired max voltage.

Some chips hardlimit at 1.20v and some do at like 1.25v or so. I believe if you want to get the maximum voltage on most PCBs you'll most likely need to shunt some transistors or buy a MSI lighting card.

I'm not sure what's wrong there but I'm pretty sure you NEED firestorm to increase voltages on that card. You are probably better off asking in the owner's club for your GPU. GL!

Hey guys, new here redface.gif great compilation of BIOSes and thread in general you have here.

I come to you seeking help for my possessed EVGA GTX 980 FTW. This is like, the 4th RMA and this current one has the "black screen, no display found" hard reboot required problem even when attempting to raise the core by +50 using the stock BIOS. And at 58c max temp too, prefer maximum performance, power options (Windows) PCI-E off, pathetic. RMA is hopeless as they keep sending me crap, so overclock.net is my last hope to attain (in my wildest dreams, right?) 1500 core.

So I read up on how it may be a failsafe, as a hard lockup like that usually means voltage/VRM apparently? So I flashed my own custom BIOS where I just lowered the voltage from the 1.20v or 1.212v to 1.137v and lo and behold the black screen of deaths are gone when benching - anything beyond what it can do just CTDs now or grey screens, but does not require a hard reboot - I can mildly OC the card (to 1416 core / 8000 memory) but anything above 1.137v and those god damned black screens come back.

ASIC quality is showing up as 75.6%.

So I ask you, how can I remedy the situation?

Is there a bios in these 600+ pages that helps or alleviates what I am talking about for the GTX 980 FTW? Or, perhaps, can someone point me to the right direction in regards to how to solve it? I read that it is a cooling VRM issue, although I'm really not sure. Maybe there's a custom mod or something you can do?

Thank you.

EDIT: Oh I forgot to add it came RMA'd with the wrong BIOS, lol. The FTW was running the reference 980 GTX BIOS, which is useless since is it VRM volt locked anyway. The card before that had a faulty fan. EVGA is really pissing me off. Can I ask for a Classified after 4 RMAs? I can dance all year with them. Maybe the 10th RMA and they'll cave!


Yes, I found out the same. 1.137v seems to be the sweet spot to fix the black screen issue on the EVGA GTX 980 FTW.
I also cooked a BIOS that limits the maximum voltage to 1.137v and sets the Core/Mem clocks to the clocks of a Reference GTX 980. (Just to be safe). You can always overclock from there and see what you can get with that voltage.

This is what I got now using MSI Afterburner: Core +170MHz / Memory +500MHz (That's 1347MHz Core Boost / 4001MHz Memory). Close enough to the original FTW Overclock.
Tested with everything I got. All 3D mark tests looped, Valley, Heaven, Catzilla, Fur, played hours of BF1 and ME:A. So far no Black screens and no other crashes.
Bios attached if anyone is interested.

I guess I could just set those OC clocks in the BIOS but for now I prefer to leave it at Reference clocks until I'm 110% sure those are stable.
So.. yea. Also those clocks might not be stable for others. So just OC the card yourself with attached BIOS and see what you get. Worst case to much OC it will just crash and recover. But it should not Black screen anymore.

Top bar on your voltage table is the target voltage. It may or may not reach it depending on your card's hard limit but setting it too high also creates instabilities
post #6438 of 6467
The max value should match on all 3 top sliders

set the 3rd slider's min value to the same as max value also to eliminate voltage throttling

http://www.overclock.net/attachments/47240hey all,
now I own an EVGA SSC 970 best buy version 3979kb. I took out the bios using gpuz and looked at it's voltage tables. the max volt allowed is 1.281. but using after burner with max volt slider I only achieve 1.243. I've tried all I can but that value doesn't increase. so is the card hard locked at 1.243 or is there something in the bios I am missing. my stable right now are 1506 and 4001 with volt at 1.243 and power at 110 stock bios. I am working on modding my bios but I wanna understand my volt condition first. also since the card has 2 x 6 pin connectors, how much can I increase my tdp to as right now I face severe throttling due to vrel vop and pwr.
I've linked my bios.

ok guys I used the op bios (AIR) Version for my gtx970 SSC best buy version all's working fine. 1531 on core and 1.281 on volt..
now can anyone help me with one question.
as I was reading through a post I came across a post of zoson where he mentioned that adjusting memory in bios disbales any control we might have through AB. Well I just upped my memory on AB by 200 to get to 4000mhz but now I am wondering that is it even effective? I mean it's only showing 4000 wth hard bios locked at 3805 or is it actually 4000 now?
