lol, I feel ridiculous with my Seasonic 1250w and 2 980s. It was handy when I was running 3 7970s (mining and gaming), and then a couple of severely overclocked 290s... now it's just comically overkill.

The card may limit power draw with only a 6 pin plugged in though so you may need a 8 pin adapter to get around that.
Yeah I know, which is why I said I do not want to buy new cables when I have plenty of power already, lol... I love my UV reactive Green 6pin cables, LOL wink.gif

I just wanted to know if these cards run with only a 6pin connected to the 8pin connectors (just incase I have to buy the 8pin GPU variety), because some cards will not even turn on unless they sense all 8 pins is infact present. At least that is what I have read at several websites and forums... I have a feeling all these more energy efficient GPU's are not enforcing such steps anymore though.

I asked this same question a few days ago but I think I need to refrase it. Do you read the oc on the core clock as 1. base clock 1126.5 + 272 = 1399 or 2. boost 1216 + 272 = 1488 or 3. taking the number from afterburner saying max core 1614. If 3. Cool! but where is that number coming from? My asic is 86.2% on a referance Gigabyte 980. 4770k oc to 4.5, moniter is an old 37" 720p tv I can oc to 1080 at 60 hz. Just looking for a little improvement on my gpu OC. Thanks RKD.

Completely, would love if someone who knows this could chime in and tell us which numbers are real. Hopefully it's the true afterburner numbers displayed while running benchmarks.

So the 980's are unlockeable depending on BIOS? I haven't been keeping up enough, mainly cuz I'm stuck waiting until January to buy my hardware but still I want to know more about everything that isthe GTX 980.

I think the only way to know for sure is to try it. I have reference cards so can't help you there, maybe someone else will be able to.

4. 71.0%

Not sure if these are average, above average, or below average.
Mine is 74.1

IIRC from this thread, asic quality doesn't mean much these days.

Yeah, that is what I am gathering. OK, so no one has tried it yet. Fair enough...

I have really nice 8pin cables sitting around somewhere, probably in the PSU box, wherever that is. Just in case I must use it... I just hope they work great with the custom sleeved 6pin cables I built though.

Let us dicuss the cards here and not any fancy cables, please..
post #2899 of 10545
Scroll two - three pages back and you will find my post.

Im using 1x6pin and 1x8pin. I asked the same question and ppl say im fine. The card seems to draw the maximum voltage but not sure about the amperage. Its true though that i should be limited by maximum power output, because 1x6pin+1x8pin deliver different wattage and surelly they dont have the same effeciency.

They are considering there are versions that have 8pin connectors on them so it is related whether or not you want to read it.

After some playing around this weekend and today it seems my card can't handle a core above 1510 or so with extended gaming sessions. I get no artifacting in benchmark runs nor during gaming sessions. Anything beyond that and after a while there will be the dreaded hang or black/grey screen. Seem to have gotten my memory to around 4050/8100. Have any of you guys that have put them under water been able to get any better overclocks ?

*Edit*

Just checked my ASIC and it is 81% o.O. Yet I am getting such a low OC. I believe mine is proof that ASIC % isn't really valid for this generation.
