We'll I don't keep it at that all the time. My 24/7 OC is 1340/2680/3251 @ 1.175v. (max boost speeds)

Power target is 111%, GPU Clock Offset is +150, Mem Clock Offset is +250. I have my fan profile set to be +10 for whatever the temperature is. The max I have hit so far is 65C, so the fan would be 75%. It's not silent, but to me it's quiet. Especially when compared to my reference 580 that I had.
Thanks man looking good. +rep

This is with auto fan maxing at about 44% speed and a +60 core clock offset, +200 memory clock offset, 111% power limit, resulting in actual speeds in-game of about 1230mhz top card, 1200mhz bottom card, once temps have hit their sustained maximums.

As far as noise, the fans are EXTREMELY quiet, even if you manually set them really high (60-65%) all you hear is the whooshing of air basically rather than any whine or pitched noise. It's a very low pitch and very quiet. If you set it to 70+% you hear a low-pitch whirring noise, as well as airflow. 46%/below is literally below the noise floor of the rest of the relatively quiet fans in my system. At 48 I can barely hear above the rest of my system if I listen, and it's not until 52% that it is really anything I'd call much different. Remember however, as I said, even in a worst-case scenario like my chasis setup currently, they don't go above 45% in the most demanding games.

These aren't even max OC's yet as I was running one card individually at around 1280-1300 with no issues gaming/3dmark (but I didn't fully stability test it alone) with the other at about 1240 alone... the lower card seems to max out at about that, though... I'm going to bump the clocks up more towards their individual maximums later tonight and test 'em out that way instead of lower in SLI. smile.gif

Awesome thanks for the info. I am just getting one for now but my main reason for selling the 680 was the value that 670 sli offers. Not that I need sli now with a 1080p monitor but I like the option later on. Especially when the price drops down the road.

I know my 680 killed it at 1080p so I am sure these will too. I one day would like to get a 1440p monitor. Which should give the card a much better workout.

I skipped "1080p", going from a 1680x1050 S-IPS Dell 2005FPW 20" all the way to a 30" Dell 3007WFP a few years ago at 2560x1600 (S-IPS). It was like gaming for the first time all over again... and the screen space + resolution is great for actual work, too. Do it as soon as you can feasibly, trust me you will LOVE it.

Thats sweet. Dell makes some sick IPS's. But I just don't have that kind of cash as I really want a 27". I have been eyeballing the korean ones and will probably get one one of these days.

I posted this elsewhere but I'll repeat it for this popular thread ...

My GB GTX670 OC overclocking info:

Stock Core Clock after 'Kepler Boost:': 1189MHz

(Apparently) Stable Overclocks So Far (lots of benches run w/o crashes/artifacts)
1) 1345c/3225m (1.162V)
2) 1325c/3600m (1.162V)

The frequencies are all actual 'observed' clocks via AB graphs during bench runs.

Drivers: 301.25

Max Voltage can be raised to 1.175 in Precision X, but won't budge over 1.162 in AB even w/voltage slider maxed. I've NOT tried OC'ing at 1.175V yet but plan to try it out in the future.

I'm also going to be running various benches to determine which of the two OC configs I prefer ... but I'm very much leaning towards the 2nd one as the better of the two. It seems worth it to lose a little core to gain a ton of memory bandwidth.

At these clocks, my temps get up to 62-65C after running for long periods at 99%.

I don't know what the fan speed is (my guess is the 45% range) but I'll tell you this ... my case runs VERY quiet as all my fans are on controllers ... and I absolutely cannot hear the card at ALL ... even after 20 minutes of benching Heaven maxed out. Not even thinking of making any fan profile, the one that's on there now works perfect.

I'd guess that at 1.175V it might be a little different but I'm pretty damn happy what this card does, in terms of noise, clocks, and temps at 1.162V so I doubt I'll push it any further, at least not for 24/7 use ...

Just adding another Giga OC result..

Mine does 1305/3645 stable for multiple passes of Heaven.

I can get single runs with the core at 1340, but its not what I would call stable. Temps stay under 70C. I am debating if I want to hassle with adding the card to my water loop (I use a CPU block with homemade holddown plate). In playing around with the fan speed, temps dont seem to be holding me back. I MIGHT be able to get another 5-10mhz stable on the core under water.

The mem OC really impressed me. I was getting small, but consistant gains in both Heaven and 3DM11 moving up in 20mhz steps. Finally saw the drop off in performance around 3670Mhz (wasnt seeing artifacts yet however). The Giga cooler cools the memory via a full contact heatspreader so this is another drawback to going to water on the core- I may lose some of my mem OC unless I make special provisions to actively cool the mem chips.

All in all, I'm happy.
