Updating my score...added another 670ftw to my system. The second card doesn't oc as well as the first one I had though... I'm a little disappointed.

^ That score is really good for sli 670? I'm about to get a second 680 and will test on air and bench then i will put them underwater and bench. 😀
 


Have you tried using Kepler bios tweeker? Looks like temps arent holding you back so you might be able to add in some more power target and boost clock. Also, vram overclock seems to help a lot with this benchmark.
 


No, I haven't messed with the Kepler bios. I've been using EVGA Precision X. With the old single card in the system, I could get an additional 100mhz on the GPU and 520mhz on the memory with just an additional 17% increase in power. With the second card in, I'm up to 18% additional power, but can only get stable with 75mhz on the GPU and 450mhz on the memory. I'm reluctant to go much higher than that, as I'm not really sure what's safe for them to run.

I'll watch GPU-Z tonight after I get off work, and see what the max voltage goes to with the 18%....I figure that's what's holding it back. There's a guy earlier in this thread that said he went to 45%...that seems a bit crazy to me....

 
In my experience on gk104 its usually the power target more than the voltage holding you back.

Have a look at KeplerGoldenBios, its a very good easy tweek if you dont want to mess with the bios too much manually.
 


Not how I understand it, its the TDP of the card. So if you have a 150w card, then 100% power target is 150w and so on.

Assuming you have the cooling and you allow the card to draw more power (increased power target), then you can raise the boost clock. If the power target is lower it might not boost as high as it reaches the target.

KGB unlocks the bios to allow a higher voltage and power target with afterburner/precisionX.
 
I see....well, I can adjust the voltage a little bit in Precision X, I might try that before I mess with the bios. A slight increase in voltage might get the GPU stable at +100mhz, and I'll try upping the power target a bit more, since I know that it's not increasing the voltage (20% voltage increase would be scary).

I have a 360mm radiator dedicated to cooling the graphics cards, so yeah, cooling shouldn't be an issue. According to HWMonitor, my max temp during these Valley runs peaked out at 41c. I noticed Valley reads the temps quite a bit hotter. Valley said peak was 49c. Water temps only went up 8c though, so....it should be good for a lot more clock, if I can get it there.

Thanks for the help, I'll let you know how it works out.
 
Ok, got it stable with the settings at 145 / 75 / 490. That's the most I can get out of it without modding the bios...and I'm just not too keen on flashing a bios, so.....that'll have to do. Disappointed that I couldn't break 3900, but...eh, that's still a pretty decent score. Never did break 50c...I've definitely got the room, should I ever decide to try it. = )

The power target is for everything... Fan speed included.

 



Power target doesnt adjust fan speed...
 


The power target is for everything on the board that consumes POWER. In simple terms - higher the fan speed the higher the power usage thus affects the power target. Thus, higher the power target the more the board will consume power without clocking down.

Fan speeds used need to be equated when OC'ing because they do directly affect power consumption. Unless of course the fans run on magic and pixie dust.

 


Ah ok, I see what you are saying now. Yes everything drawing power on the graphics card is included in the TDP and power target. That said, the fans on a graphics card draw next to nothing in comparison to the GPU, so dont really need to be factored in.

A higher power target will allow higher speed before clocking down, but only if the temps stay below the thresholds.
 



Exactly. Reason many mod but raising the power target beyond a certain point is meaningless. An axample is my 680 DC2T's. Vanilla PT was 157% and never came close to that even after modding their bios's. On them, I was limited by the overclockability of the GPU's themselves (which were phenominal).
 


Yeah my card had a silly low power target, so I adjusted it and the boost clock and limit with kepler bios tweeker. despite being a much lower gk104 (1152 core), it overclocks like crazy with the cooling taken care of.
 


I've had about 3500 out of it in a little benchmarking run but I'm only on air so I don't want to damage anything!

EDIT: Nikoli, how come you score sheet has the HD 3000 and a 780? Are you using Virtu MVP 2?
 


I'm on a z68 board and yes, virtu is running in the background powering a 32" 720p monitor.

even on air you should be able to get to roughly 1.3ghz. just let it run at a 70% constant fan and see how much you can get out of it without going too much over 82c. your not going to damage anything just using precision/afterburner limits. you would need to use the classified voltage tool to push core and memory voltages up high enough to hurt anything. plus its evga, you got the best warranty around.
