    Yup, I've never liked the look/design of the STRIX cards in the first place and now I got some first hand experience straight in my face :puke2: Not to whine though, I did get the card for just 200 euros.

    Yesterday-today I experienced a very interesting problem regarding my SLI setup. As I was casually enjoying myself some R6 with a couple of pals and a pint of mead I noticed some radical color banding. I immediately thought I fuqqed up the color management (ICC) profiles on the monitor as I had tweaked those earlier that day. So I started to troubleshoot, tried everything I could think of inside Windows and in the end I went on and reinstalled Win 10. Didn't help, so then I thought maybe broke something on the ASUS card as I was putting the spacers on it. So I took it out, removed the spacers, backplate, cooler and literally everything on the card and inspected it all around. It was intact and not harmed in any way so I put the it back together. Didn't help - Still banding.
    So I swapped the cards around. Green lines start to flicker all over the monitor and insane banding in 3DMark. I thought what the duck?!
    Then I tried both cards in single config, no banding/flicker to be seen so I suspected it's got to be the SLI bridge. As I took a look inside the SLI bridge's mounting inserts there was a small piece of hair/dust inside the bridge. I took some compressed air and blew that crap out of there. And voila, after hours of troubleshooting, reinstalling Windows and disassembling the cards it was just a piece of dust inside the SLI bridge. I think I need to book myself in to a mental institute now lol :eyebrows:

    Well at least nothing is broken :banana:

    Yep those bridges can be annoying, especially the cheap flex bridges.

    So I have to RMA my 980Ti back to EVGA :( I did have a custom bios installed which I have flashed back to a stock one from techpowerup. I wasn't sure if the .rom file name needed to be stock as well? Would this even matter for an RMA as long as the bios file is stock/untouched?

    It will be fine if the image was original.

    The filename has nothing to do with the data that gets flashed to the card. It's not visible to anyone but you.

    However, it is possible that they know the card has been flashed. The card might have an internal flag or counter that can be queried by technicians.

    Won't matter as EVGA provides bios updates if you ask for it.

    Hi guys,

    Trying to unlock raising the voltage on 980 Ti Kingpin videocard which is suppose to be locked at 1.212 volts. Problem is I have tried using the Maxwell II bios editor to raise the voltage to 1250mv by changing 1212mv to 1250mv and when I run Afterburner it reports it wont go over 1212mv no matter what value I change.

    [​IMG]

    I have changed the orange and purple underlined fields to 1250 and even as DeathAngel74 suggested opened the file in the Kepler bios editor and saved which opened up three more hidden voltage table fields just like the first which I duplicated as the first. Detailed here: https://forums.guru3d.com/threads/980-ti-owners-thread.399607/page-106#post-5240816

    So far Afterburner doesn't show any increase in highest voltage supplied at 1212mv in the overlay display. Interestingly enough though its voltage slider is now in the middle at default 0 volts where before it was all way to the left. Not sure if thats significant.

    Also to make matters worse shortly thereafter this mod one of my LEDs on my gpu burns out and doesn't come back on anymore. Only blinks for a super quick fraction of a second when machine is powered on. Fortunately the gpu's still function. Just without the LED being on.. :(

    Thanks

    Hi there!

    I can't remember for sure but maybe you needed to edit the CLK values as well for the highest states to match what you've set in P00...P and P05.

    Don't have a 980 Ti anymore so it's been a while.

    Btw if the voltage regulator won't go over 1.212 then editing the BIOS won't change that I think. If it's "hard" capped.

    @Agent-A01

    help with this one?

    Edit: purple field is not 1250 but 1306.3 based on your screengrab, try changing it first.

    Actually test to see if you get any clock scaling from extra voltage.
    MSI AB may not be polling the correct voltage and may only be seeing the software voltage reported by nvapi.

    Some cards don't report voltage correctly out of the box in MSI ab, you may try checking with a DMM.

    Funny story doesn't take much voltage to get 1500mhz stable so who needs more voltage anyhow but figured out how to do it by software at least and with my 980 ti the voltage requirement for another 100mhz is sick and not worth it.

    Is it really at 1500mhz able to reach 1070ti performance levels?

    Yeah, pretty much, if not surpass it. My 980ti at 1500mhz was a match for stock 1080, no problem. This was 2 years ago though, I would think since then, the 1080/1070ti improved a little bit with new drivers. Still, the 980ti at 1500mhz is a great card.

    Yeah I was able to get 1506/4000 stable at 1.2 v as far as I can tell. Tested it with various 3D benchmarks then customized my rom to 'Bake-in' 1506 as the default TDP Boost clock entry. Unfortunately for some reason while gaming it Boosted down to 1341!

    I couldn't understand why it would Boost down or throttle as I raised my TDP values in MBT but it was using clock state #61 instead of #74 which I had set to 1506. So I had to shift down the values in the Boost table and shift up the voltage table to match.

    Now it will auto Boost to 1506 and throttle down normally but I kind of cheated here it feels like.

    If anyone knows why please comment.

    Thanks.
