Evening

Bought this card last night. What can i say, i was expecting a lot from this card especially for the price. Tri-fan dual slot cooler seems to do the job, having said that my idle is 27 and load on BF3 is 75-79c, with 140mm viper blowing on it all the time, case cooling is pretty decent as well.

OC-wise, i was expecting to oc to at least 1300 core, which did ot happend. In fact i couldnt OC core at all, managed to oc memory to 6500 though.

With extra bits added to the card this sort of oc is not really acceptable.

BF3 plays well on ultra with motion blur disabled as i dont like that

I am yet to test 3d performance, but so far, very disapointed.
 
Please stop encouraging people to DSR cards just because they don't over clock as high as people may like, it carries a cost and that cost is passed onto us as increased prices.
Its not as if an extra 40-50 MHz on the core makes much difference anyway, the keplers scale better with memory increase as they are bandwidth starved.
 
So whats the boost on the core?
As others will say not really a valid reason to DSR, even though I do OC mine for benchies etc I don't for gaming.
 
LOL mine doesn't OC either, but that said I don't usually OC cards anyway, see not point when games play above and beyond reasonable frame rates. I just did this as a test but it fails every time on any OC with heaven 3.
 
Not interested in overclocking so not even trying. Card runs BF3 at max settings/4xMSAA at 1080p at a nice and smooth vsync 60fps, so rather happy with my purchase :D Gets to about 74-78c in BF3 like CivilDrone, but this is in a totally silent case. If I wack the case fans up and set fan speed on graphics card to 60% it is audible, but hovers closer to 60c. At idle it's around 33c and silent :D
 
I think people posting up about not worrying about what OC they get is missing the point

this is the LTD card that was supposed to be;

You'd be very unlucky to get a White edition 680 which could not do 1300mhz plus on the core!

Remember they boost to 1267mhz out the box which I believe is the fastest of all the 680s :)

it's over £100 more than a standard 680, so to get one that barely sneaks in an OC equal to a stock 680 is seriously dissapointing

this card was supposed to be built from the ground up for overclocking - voltage control, 2x8pin pcie connectors, monitoring, 300W TDP...

it's running hot and won't OC... WTF!?
I would be returning it personally as this is clearly false advertising

A stock 680 runs at 1058MHz boost and at launch they mostly overclocked very well. But 680's are now not clocking as well, some seeing no greater than 1140MHz on the core.

The KFA2 LTD OC boost out the box at 1267MHz which is higher than many can overclock too.

I did not say they all will do 1300MHz but those that can't would be unlucky. We've built a system with two in and managed 1322MHz on both cards with the voltage maxed at 1322MHz.

Also 79c underload for a 680 is not hot, far from it. Especially when you consider the clock speeds this card is at.

Fact is if I was buying a 680 the KFA2 would be my choice as in our testing 1200MHz+ does not come easy on 680's now, yet KFA guarantee that out the box. :)

What he said, I paid extra for a guaranteed overclock over a stock 680, an awesome cooling system (I can't hear it on load when it hits 75c on BF3) and a sexy looking white LED pulsing BEAST!

Just to clarify, I wasn't having a pop at you, but at KFA2, who have advertised the card as having lots of OC features (like voltage control) but then if you don't manage an increase of even +1 mhz...
looking at the specs on the site, they now only come with 1215mhz boost?

if 680's in general are now not hitting 1200's then even more reason to go 670 :D

It's also interesting about 680s not overclocking well anymore. Perhaps nVidia are building the 680s now with worse chips to relieve stock issues.

...or building them with overclocked 670s :p

I have to agree with some of the other posts about the KFA2s. I had to change my GTX 670 EX OC cards because in my setup using SLI, I couldn't keep the temps below the high 90s at stock and ended up having to go for reference cards so the heat would be vented out the back. :( I ended up changing them for the EVGA SC 4GB cards, (for a bit of future proofing and I'm running multi monitor), which would've made OcUK happy as it cost me nearly £200 extra! :mad:

Taking all that into account, letting the KFA2 cards go was really difficult and if it wasn't for the temps or if I wasn't running SLI, I would've kept them and lived with 2GB because apart from the massive price difference to have 4GB, the KFA2 cards really do clock very highly.

Out of the box, one of the cards at stock would boost to 1167MHz and the other to 1202MHz when running Heaven at extreme levels on multi-monitor and for some reason, in SLI, GPU-Z would show the maximum boost at 1258MHz and keep in mind that I hadn't applied any overclock using Precision X or Afterburner and these are 670s not 680s!

In contrast, the EVGA cards are more expensive, but only boost to 1137MHz either individually or in SLI. If I try any kind of OC no matter how small, Heaven 3.0 will crash.

To the OP, have you tried the latest beta drivers because one of the key fixes is to stop pre-overclocked cards from defaulting to lower clocks?
 
I have to say I would be jarred off if I paid £550 for a card with only 2gb ram, was advertised as being made for overclocking , and it won't even over clock by 30mhz :mad:
Not even a 3% overclock :p
