    A second one? :D
    Grats anyway, finally the advanced custom cards are coming in.

    Nono not SLi :) I had a 780 Phantom and replaced it with a 980 Phantom! Looks are so beautiful!

    No, I meant it as a response to 'what more can I ask for?'. Well, a second one of the 980 Phantom ;)

    Sorry for late reply been busy, its in the overclock.net 980 somewhere.
    I think I remember the poster jpmboy talking about it. There was definitely somebody talking about it.

    Those kingpins look good, wonder how much you can push those under water for 24/7 use. I would've expected atleast 1600mhz or more. Do they have increased power phases? Are i2c commands allowed? I doubt i2c commands are allowed as there will be too much change to the architecture. The datasheet should show this, dont know if there will be a separate datasheet for the kingpin though.

    Nice cards though, dont come much better than the kingpin.

    So I have been messing around with my Evga Ref SC 980 the pass week after I got my water block put on. Right now I am using afterbrner to OC the card. I have the voltage bar maxed out and the power target bar maxed as well. I have the card running at +150 core and +300 mem. Boost clocks for the core are 1550mhz and the mem runs at 3800mhz. I have yet to crash the card stressing it with 3dmark and playing games at those clocks. Temps never go over 43c remember the card is on water. My water block is a EK block which is the same block that Evga uses for its Evga hydro cooler. My question is, does the card become faster with higher core clocks or higher mem clocks, or a mix of both. My 660 GTX ran faster when I OCed the mem more then the core but I know some cards are faster with the core then the mem. After I get the max I can do I will post pics of everything just looking for info right now.

    As i said the other day, those OC's can be stable on Benchmark for hours, will not be stable on real gaming

    Open Dying light with last patch, go to the roof of "The tower", go to the yellow Crane, look to the sky more than the city, move around there for a few minutes, watch the game CTD with "-Device removed" error, no matter the driver you're using

    I was stable on 180/600 for 1hour in heaven, without any drop on framerate, then i go to that place on Dying Light and.. Tada~~, full brown screen, then CTD

    That game uses a lot of CPU, also GPU, its not very well optimised, thats why its good to see if the OC is stable or not, and i have to down my 180 to 96 to make it stable and do not crash, so....

    And yes, i have a pagefile of 8GB, and i have 8GB ram

    Just pulled the trigger on a GTX 980 SC yesterday from Newegg. I'm hoping that it will be that "sweet spot" among the 980 lineup. Considering it was only $3 more than the standard clocked version, I'd say that's probably EVGA's bang for the buck on Newegg. Now quite the FTW version, but I wasn't about to go $20 above the normal clocked version to do it.

    This is the easiest card I have ever overclocked! something strange however, touch the memory and performance drops!

    Could go a lot higher but can't see the advantage to start altering power and generating heat, presently with over boost it tops out at 1567 MHz

    Anybody came across a handy 980 BIOS for the Strix version?

    take a look at these http://www.overclock.net/t/1517316/...d-980-firmware-zosons-h2o-and-air-custom-bios that is linked in the OP as well. the H20 one is the only one I have been able to use to get my card sable that those speeds. Since your card is a Strix not a SC card you can just copy and paste the clock/voltage tables from the modded bios to your bios. That page has a guide on what to do.

    Thanks for the reply. I'm currently in the process of reading through this thread, made it to page 75 yesterday until my brain became unstable ;)

    Unfortunately I can't download the BIOSs from there as I'm not registered, so I try to tailor my own currently (downloaded reference BIOS and the last version tools).

    I was just curious if there's any other 980 Strix user's here, but that card seems to be on the rare side, it feels like the smalles group of all overclockers bought it, hence my question.

    Thanks for linking it and the download cowie, I stumbled upon the thread yesterday and it's on my list to read :)
    Still got 280 pages left on overclock.net... and there it's only for bios modding. This sure seems to be a lot more complicated than with Fermi!

    Heh, looks like I'm screwed anyway. Nvidia does not allow two cards with custom BIOS to run in SLI, the second one seems to revert to stock bios all the time. I have to do some research on this, but if it is true, it's a f*cking disgrace. I buy two of their cards and get screwed over as a result?

    That would be an incorrect assumption, what do you mean it reverts? Flash failed or?

    [edit] Yes, reverting to stock bios was an incorrect assumption on my side, it's just that it looks like SLI does have different voltages, as it tries to balance clocks, not voltages on cards, and sometimes making cards drop their voltage, thus making overclocks unstable on one of the two cards, ending in a TDR or game crash (see threads below).


    Actually not, I've stumbled across this when reading the custom bios thread (Zoson's) on overclock.net, which was referring to the problem that both cards run in single mode show a successful flash (and stable overclocks), but when put into (dual) SLI mode, the bottom card drops back to stock bios voltages but the overclock, thus resulting in instabilities and driver crashes.


    A google search then pointed out the following to me, as I did not have time to continue reading the thread at overclock:

    This thread on the geforce forums seems to referr to the mentioned problem:
    https://forums.geforce.com/default/topic/777448/-major-issue-sli-gtx-970-cards-one-card-runs-way-lower-voltage-than-the-other-driver-bug-/

    A thread on the EVGA forums also about this issue, where it's said to be a problem with monitoring software readouts, again it's hard to say if you don't have a multimeter:
    http://forums.evga.com/GTX-980970-SLI-voltage-mismatching-issue-m2244800.aspx

    And a thread at hardforum also mentioning odd discrepancies with voltages and SLI use:
    http://hardforum.com/showthread.php?t=1837361


    Has any body come across such a problem when using 970s or 980s in SLI? I guess it's a particular problem with overclocks and modded BIOSs, but if so I'm already thinking of selling my two 980s, although they've never run a single game... it's like they're brand new, one hasn't even left the box...

    I have to do additional research, but I thought I'd ask my fellow gurus if they experienced similar problems.
