Every card is different and when pairing them in SLI no doubt you will have to find a happy medium that both cards are happy with. I say you done well!

Hey Darylrese, so you're saying you gotta max out voltage and power in order to have Core Clocks above 1200 or Boost above 1200?

Nope , my card is crashing even if i underclock it by 80Mhz , adding voltage or power limit does not help either it only lasted 2 loops of Heaven , it is faulty and many more people have this issue.
Lastly even if underclocking or adding voltage would fix the issue that's not what i paid for , i paid for factory OC'd card and that's how it supposed to work , i don't expect it to overclock behind stock but it must be stable out of the box.
At lest EVGA is acknowledging the issues with their GTX670 SC and ASUS is ignoring this so far.

Also, this is the first time I even have a high quality GPU, so not sure how much mhz I'd be happy being able overclock my cards over the "true" core clock of 1058.
I'm just stating a possible case that explains the instability. And all evidence points to the hypothesis that Asus is not lying to people about the card ability, they just accidentally set the cards to 1137 stock instead of 1058. I cannot find any statements about "Core Clocks 1137 mhz." Everywhere it reads 1058 stock and 1137 boost clocks.\
Note: I may be a noob and please explain to me how I'm wrong. Thanks!

This has been discussed pretty extensively. Can you post a screenshot of your GPU-Z? Mine reads 1058 base clock, 1137 boost clock. What Asus, we all think, did not account for is the "Kepler Boost" as it has been dubbed, which is individual to each card. On average cards are boosting up to 1240-1280 at stock settings which is a KB of 100-140. These cards are only guaranteed to run 1137mhz, but kepler boost brings them far above that at stock settings, making some cards unstable out of the box. There are very few (if any) cards that are unstable at 1137mhz. That said, if it is not stable out of the box, I highly suggest returning it. A lot have mentioned it being a problem when it comes to resale value, and from the consumer perspective, it really just sucks to have to tinker with your brand new $430 dollar toy just to get it to not crash.

So i clocked them differently and have them stable at 1280 and +325 on both cards for the vram. But they wont go any higher than 1280 without crashing in 3dmark11. Are these cocks fair for the TOP's or are these defective?? Oh im also putting +75mv into them to achieve these numbers and have the power limit set to 117%

I had the same problem ,my top card is boosting to 1280 and bottom to 1267 but in SLI they crash constantly , i decided to test them separately and it turns out one of them is faulty , the other one works great , did you try testing them on their own ?

can't open gpu-z for some reason, it "stops responding" as soon as i open it. i'm wrong about the clock thing. i wanted to rationalize not having to RMA these i guess smile.gif

both stock and max heaven crashes in a few minutes for me on SLI. both msi afterburner and gpu tweak say clocks for one card are 1215 and for other is 1245-1254.

edit: the 1215 card crashes in 1-3 minutes on stock and max heaven
the 1254 card is lasting longer 1hr+ in max heaven

I don't think he was addressing your issue, dude. Seanay was asking if his cards only OC'd to 1280 does that make them defective, and that's who Daryl was talking to, telling him no it doesn't make 'em defective thumb.gif

I think we're all pretty much in agreement that any downclocking to get a card to run at stock should be considered unacceptable, and the cards should be returned. Esp. since Asus hasn't addressed the matter at all.

Right i got confused there a little , anyway something is wrong with some TOP cards , after underclocking my cards -80Mhz I'm able to play 2/3 rounds of BF3 without crash and they managed to survive 2 passes of Heaven lol
Like i said one of them is working fine so this just shows it's kind of a lottery.
Taking my card back to the store tomorrow , bad part is they're out of stock for Direct Cu and Direct CU TOP so i will have to take refund mad.gif
I hope i will be able to get one somewhere else.

Stock clocks on this card is supposed to be STOCK CORE CLOCK at 1058 and BOOST at 1137. Asus messed up, making the cards all STOCK CORE CLOCK at 1137 instead of 1058.
Check out the Spec Page:
http://www.asus.com/Graphics_Cards/NVIDIA_Series/GTX670DC2T2GD5/#specifications
I'm going to downclock these cards and not RMA them. There's no point. Sure there's some lucky people stable at STOCK CORE CLOCK 1137 (not me and my SLI of these cards) but these cards were supposed to 1058 STOCK CORE CLOCK. So if your card is completely stable at 1058 CORE CLOCK, then all is good. Even Techpowerup's 10/10 review for this card was using 1058 CORE and 1137 BOOST (http://www.techpowerup.com/reviews/ASUS/GeForce_GTX_670_Direct_Cu_II/). So everyone stop your whining and DOWNCLOCK your cards.
Note: This is my unofficial analysis and I have NOT questioned Asus about this. But this case sounds totally plausible.



man i dunno if that is 100% right but i just ran haven all they way through after doin what u sugested for the first time without the driver failing (well i clicked the 's' on gpu tweek to reduce to stock). Seems to have done the trick.
So asus just oc'ed the card too high by default on tweek then?

i'm really not sure if that hypothesis is right. I just tested my cards and one is good and one is horrendous. so i may be wrong. i'm an overclock noob.
when i made that post, i thought the core clocks were at 1137 because you saw that on the gpu tweak. so in reality there's two boosts? core clock is 1058, 1st boost is 1137 and 2nd boost takes it to 1200+?

edit: can't decide if I'm going to keep the good card and get another one later, or just get rid of both and wait for MSI GTX 680 Lightning

An sli setup might give you a hard time on some games, especially on new games since drivers havent matured for that title, Im a big fan of one gpu after playing with a 560ti sli in my rig a week or so when bf3 launched. It was easier to just go to a single gtx570 back then.

With one gtx670 you should be able to max out just about anything on a 1080p monitor, you may not need an sli 670 setup or 680 unless your planning on something higher like 2560x1440. That said you need to be at peace with what you purchased, if a 680 is what you want get it.
