I'm the exact opposite! I have to have non-blower cards just for aesthetics. I'm stupid, I know....

It's all good man I understand that. I would care a lot more about aesthetics but I keep my PC in a closet ten feet away. tongue.gif

I have a weird thing for fans and airflow though. We all have our quirks. The inside of my case is super clean not a wire to be seen and I keep it tucked away. I did cable management purely for the airflow. If your curious how my fans are setup got a pic in my profile. I switched cases but the positioning is the same. I'm hoping one day I get motivated enough to WC everything in this new 810 I got.

Edit: God dude your case is beautiful. Keep doing what your doing bro. Amazing work. I love the color scheme it's exactly what I went for when changing to the switch. My red AMD card sticks out though obviously. Mainly got it for WC in which case it won't matter. I absolutely love white/black sleeves and a white/black case.

Anyone having any insight on this?

Friend and I both have our 680s at +120 now. Yet his core is 1230 and mine is 1202 with both cards rendering the same thing at 100% load. His card also stays at a sustained 1.175v, while mine steps down to 1.164v after a few seconds of load (and then becomes unstable). Exact same settings.

Overclocking on these cards is an extreme hit or miss. EVGAJacob on twitter said we will NOT get voltage control on these because they are at the limit of 2x 6-pin. Voltage control would require an 8-pin. The overclocks we are getting are the max our card will ever get... non-reference cards will overclock much better. There's is no reason to watercool reference 680s since max OC is easily obtained with reference cooling.
Not exactly happy with that information, may return the card. I will be getting a GK110 when it comes out so I may just deal with it.

These things are strange animals. With two cards in SLI one of them clocks 55 MHz lower even though they are set the same in precision. The max OC I have found stable in all programs is 120/300 in SLI. They are still a bit faster than my EVGA Ultra Classified 580's, but nothing to write home about. I will most likely sell all four of my vanilla 680's and get four EVGA Classified Hydro-Coppers when they launch, and then "big Kepler" later in the year. So that will be about four series of GPU's I will have in one year LOL.

7970 -> 2GB 680 -> 4GB 680 -> Big Kepler all in 2012. biggrin.gif

I don't understand why nvidia would be pushing 1175mv out of the box where as max volts allowable in afterburner for me for my 45nm 570gtx is 1100mv. Also consider they screwed you guys with one less VRM than the pre release leaked PCB, maybe that's why they didn't want you to crank the volts. I am hoping at least 1.21v is doable with the next afterburner update...

I'm waiting to see if anyone burns their VRM's overclocking this thing as I've killed 2x vanilla 570gtx benching at 1100mv so I'm skeptical about 4vrm cards.

I really wanna upgrade my video card but no lightnings are out yet I gotta wait... can you imagine what damage 680gtx@ 1.3v would do in benchmarks?

I can't believe EVGA jacob said they will never have voltage control on these cards. If that's not a huge blow to the OCing community I don't know what is. Considering the really good temps you guys are getting it doesn't look like water would really help anything either if you can't over volt. Seems to me as if Nvidia clocked this thing really high out of the gate. Even if a pencil mod does work it shouldn't be neccessary for your 500 dollar video card.

Woa....950 core on a GTX 480? For a water cooled 480 that would be very good and for a air cooled you basically had a golden 480.

What kind of vcore are you guys seeing on these cards?

1.16V seems a little high for stock settings running BF3 @ roughly 1056Mhz. This is also not a very quiet card. :/

The maximum stable (within 5MHz) of both my friend's and mine cards are 120/455. 5Mhz higher on memory or core results in both artifacting and/or crashing. These cards aren't in the same system. We got them in the same shipment.. so kind of expected them to be similiar in overclocking but they seem to be EXACTLY the same. His boost 28MHz higher than mine though... I PMed EVGAJacob about it and he said it's normal for some cards to boost higher than others. Consider boost is on 100% of the time for us when we are benchmarking heaven, or playing a modern game, it's a big deal.

I'm not sure about you but that's a slippery slope. Even at stock his card boosts 28MHz higher than mine, and I feel that boost should not vary between cards. You said yourself, one of yours runs 55MHz lower. You paid the same for both, yet one card is superior even if you aren't overclocking. I'm not sure I like that.

My card is pretty much dead silent until 70%? Max is 85%. I can keep my card at 68C and not even hear the fan, which is about 65% fan.

You can't adjust the voltage. The most you can do is force 1.175v which ensures the card uses 1.175v when it's under load, but nothing else. 1.175v is the stock load voltage so your not doing anything unless your card is like mine and likes to step down to 1.164v and then crash the program because of it.

Mine doesn't run loud at all, I actually only hear it over my case fans when it hits 72% speed (Mind you through none of my benchmarking have I seen it go past 64%).

When it hits 85% though, yeah it's ridiculously loud, but considering even my mild OC hasn't pushed it into needing the 70%'s after a few hours I don't think noise should be a factor for anyone running this card.
