So how about this, everyone who has gotten a 670 and wants to overclock it, post your results in this thread and I'll keep the OP updated with some graphs to see if we can work out if there are any conclusions to be drawn.

I will need each of you to post;

Make & Model:
Best Boost clock:
Temp:
Noise:
Heaven Score:
Heaven Avg. FPS:


Make and model are pretty self explanatory, but also note here if you've modified the card in any way - aftermarket cooler or water block etc.

When I say "BEST" boost clock, I don't mean maximum when you first start up, I mean after your card gets up to operating temp, then what does the card tend to run at... so if you are hitting 70 or 80C, what does it then run at.
just to clarify, the best clock doesn't need to be in heaven, it can be your favourite game or other benchmark, which ever is the most consistent (e.g. if heaven is the lowest and another benchmark + game both show the higher clock then go with the higher one)
Game Stable boosts only please.

If you want to run heaven and post scores you can (for settings please use 1920x1080, 4xAA, 4xAF and Normal Tess as per the other thread just to try to keep some consistency). Links to screenshots (don't have to be full size) of afterburner and heaven would be appreciated but not essential. I'm not running a leader board here so there's nothing to gain by lying.

Noise: now this will be the most subjective one as we don't all have DB meters at home, but what I would like is one of the following:

None basically this is where you can just barely hear it, or even can't hear it at all over the noise of your case fans (if you have a particularly noisy CPU heatsink/fan then please note this)

Audible this is where you can hear it as a distinct noise but not annoyingly so

Noisy this is where to get the OC that you've posted up you have to set the fan up to a point that it is clearly audible and without something like headphones on you would find it annoying in an otherwise quiet room


I'd prefer if people kept chat to a minimum on this thread (either go to the main 670 thread or start a new one) as it'll start to make things difficult for me to keep this one updated if there's too much chatter and not enough results. I'll be keeping a note of usernames too so if you achieve a better clock, don't worry I won't count you twice, I'll use your most recent one - so if you get a better clock or if your previous best is no longer stable I'll keep that updated too.

If you are in the process of OCing your card, please don't post up every 20 minutes saying "no I've got this, then this, then this"... do your OC, spend a day on it and then post up your result.

Hopefully we'll start to see if there is any pattern to a particular card doing a high OC, or if it's just random... I'm also hoping we get a few watercooled cards in so that we can see if the long PCB cards still beat the short ones when watercooled or not, so people can make an informed decision based on a wide spread of data instead of a few reviews which may or may not have been cherry picked review samples.

Fair enough :)

I'll start off...

Gigabyte Windforce 3X GTX670 2GB
1350mhz core 7160 memory (effective). (will go slightly higher for non-heaven benchmarks)
Highest temp hasn't gone over 60c on air, though the card is being watercooled today.
Noise is silent at idle, it can get quite loud over 50% though headphones block it out completely.
Heaven Score: 2119
Heaven avg fps: 84.1

Heaven testing done @ OcUK 1080p standards.

Will keep you updated with whats happening under water too.

Edit: Could we also keep the AMD vs Nvidia chat to a bare minimum, almost every thread on here over the last week has been trashed due to pointless bickering.

thanks!

I'll stick with heaven as it puts a similar amount of load as BF3 onto the card, if an OC failed in Heaven I wouldn't trust it in BF3 either :)

Just leak testing now :o
 
Make & Model: KFA2 EX OC 670
Best Boost clock: 1229Mhz,
Temp: 65-69 depending on the ambient temp, this morning the sun has been shining in the room for a few hours (what an excuse lol) (at 1229, custom fan profile, if it touches 70 degrees clock will drop to 1189)
Noise: quieter than my H100 (push only)
Heaven Score: 2046
Heaven Avg. FPS: 84 I think

Under water thus far is going really well.

It seems direct power consumption is tied into some other sensor I think, 85% consumption under air, 73% under water. Just testing for a maximum clock, currently sitting at 1374mhz and still climbing :)
 
Make & Model: KFA2
Best Boost clock: 1260 Mhz
Temp: 66 degrees
Noise: quiet after a cooler reseat

OCUK required settings are BS for testing these cards, I only run 8x AA, 16x AF, Extreme tesselation.

I'll remove my heaven results then, they are too extreme for this thread it seems.
 
He has to be mistaken or running different settings to the standard OcUK ones since he scores lower than my reference OC MSI card.

Oh hey there.

Got 2 of those cards waiting for me at home to run in SLI.

Can you tell me how you find temps and noise?

Are you happy with the card? As said in other threads, am worried about the whining some people mention on the ref coolers.

You really do come across as an angry, miserable person.

Not just here, but on the nvidia forums too.

Is there any good reason, or just miserable for the sake of it?

Temps get up to 82c, at this temp the fan can get pretty whiny, you may not be as sensitive but I couldn't put up with it and ordered a Windforce and am returning my MSI tomorrow.
