***Official GTX 670 thread***

My ASIC quality is 100% :)

In case people don't know how to find it out, just do this:

run gpu-z
right click on the title bar and click ASIC quality
for multi-gpu users it will only tell u one card at a time, switch the cards at the bottom and it will tell u the score for that gpu :)

Is EVGA's Superclock model just the reference model with a higher overclock or does it offer anything else?

it's the same as the base EVGA... they both have a high flow rear bracket and bigger than reference heatsink, but the EVGA 670 and 670 SC are the same other than the clock difference

1300+ is a very very good OC for an EVGA, mine does 1280 but only if I set the fan to full (85%) which is then noisy... but then I have a waterblock sat here waiting to go on too so I'll see what that gives me

the power target is largely meaningless - cards like the windforce have theirs pre-set to something higher than base models due to the factory OC, so a windforce at 111% is the same as a reference card at 122%... just set it to max and let the card do it's own thing, they all top out at 1.175v anyway so having a higher power target won't do anything useful

I don't understand how a GTX670 can get a 100% ASIC quality, if it was that perfect it would be used as a GTX680. :p

I still think that the GPU-Z ASIC thing is nonsense for the most part.
 
Maybe gigabyte got some 680 gpus mixed up with the 670s :p. It really doesn't mean anything to me really, the card plays everything maxed out and is cool and quiet. That's what matters :). I really should see how well mine overclocks at some point.

I'd guess the fused off segment of the GPU core is not counted. Hence what is left is 100%. In a way its likely 670's have higher ASIC qulity as they fuse off a dodgy bit of the chip to leave a better average left.

Where on the 680 its the ASIC measure of the entire chip, on the 670 the ASIC is the measure of the best bits of the chip!

Or its just some random rubbish! :p

Yeah that would make sense but afaik the readout has changed a few times between GPU-Z versions and some people have scored more than 100% with their cards, so I think it's just some crappy algorithm they're using.
 
I'm so excited to get my second Windforce 670 on Saturday for my first SLI, few weeks and I should have my XL2420T for 120hz :D

I'm intrigued at what the temperatures will be and I hope I get another excellent overclocking card, do you guys think its wise to get an exhaust fan here on my case:

To take the excess heat away faster? All other fans are exhaust I believe, I just have the standard NZXT Phantom 410 fans. 140mm in the top, 120mm in the front and top rear.
 
For non-ref cards in SLI, extra fans placed somewhat between the cards are recommended. I read somewhere that a guy SLIed two gtx670s windforce in a closed case and get around 100c from the top card before it shut itself down.
 
Signing in, my Windforce 670 is arriving today. :)

I've not had a green card since 2008, so getting used to driver names and how the OC stuff works will take some reading. :)

Not that I'm really bothered but up to getting my 670GTX I used to think that was easy to overclock a GPU. I'm just glad that I do not need to now, even with running at 2560x1440 it still performs great.

Got my DCII non top a few days ago. Managed to get the boost clock to 1095, with it maxing out at 1215MHz in games, and the memory at 6800MHz effective. Not the highest overclock I've seen but is this acceptable? Is there anyway to get it higher? I noticed afterburner had voltage control, would increasing this help?

No voltage control unfortunately so far for Kepler.
 
It all depends what your default has been set to. Some cards' "default" is set to the maximum allowed already, some are set below this.

No matter what utilities claim, check what it actually runs at.
