+50 on Core

Does anybody know why the hell I can't get "high" Clocks ?
1202 is about right for a gigabyte windforce, mine is also 1202 for gaming, I can stay stable at 1215 in Guildwars 2 but that is the absolute limit. Cooling the card further won't help at all, set a decent fan profile and leave it be. Your memory overclock is excellent anyway smile.gif mine is usually +650 in my 1202 OC and I have to drop the memory clock for my Guildwars OC down to +550.
The gigabyte cards just aren't massive core overclockers, but they are great cards, the 3 fans keep them very very cool with the right fan profile and let's face it they look freakin sweet tongue.gif
Anyway, 1202 isn't exactly low biggrin.gif

Hello guys,
I'm just testing my new graphic card ( GTX670-DC2-2GD5 ), the "problem" are the values of the GPU clock, supposedly my card should have a boost of 980 MHz, but the card runs at 1071 MHz under load (see image). this is normal ?, how this may affect overclocking ?, the working voltages are correct ? why the "power target" can have a value greater than 100% if I have not changed yet ?. THANK !!

LOAD

IDLE

Yes, it's normal. Each card has it's own boost clock speed that it will run at - the number on the box is just the average boost speed. It won't really affect your overclocking, the offset you add (via the sliders) will just get added to whatever the card's boost clock is. So for you +100 would give you 1171, while +100 might give someone else 1150.

Not sure what you mean about the power target. You can adjust it to allow the card to draw more than the standard amount of power, which will allow the card to boost to a higher clock (well, actually just keep it from throttling, but same difference). It is best just to put that over to the max and leave it there. If you are talking about it being 100.6%, that's just a minor blip above 100% since the card can't react instantaneously to increased power draw (it is reacting, not predicting).

This is completely normal. The 980mhz value specified by Asus, is the minimum guaranteed speed your card will run at, under all circumstances. The rest is caused by nVidias boost technology, allowing your card to run faster, when withing certain power consumption and/or temperature limits. (other limits factor in, but these are the two most commond).

The power target is known to fluctuate around your maximum value, on average, the card won't pass the 100% limit anyways. The power slider shoud always be maxed, if you are overclocked.

These are not "problems" but results of the nVidia Boost 1.0 technology. Just wait for Boost 2.0, when the voltage will be all over as well wink.gif

Great article. I just have a couple of questions:

In the 'Quick' version of the overclocking process, it says set the power target and voltage both to maximum, temporarily. But then there's nothing afterwards about reducing them back down. Does anyone have any suggestions about this? I'm guessing leaving them both at maximum may impact on the card's lifespan?

Also, for SLI users, what is the best way to go about overclocking? Just sync the card settings in Precision?

Many thanks in advance.

try lowering them after you found the max stable clock. reduce a little then test, reduce more then test. repeat this until you found your lowest slider settings.
no it wont hurt the lifespan of the card. this is what it does naturally except the voltage doesnt react quick enough to keep from crashing when a load is instantly applied.
the only way you can sync overclock is if both cards have identical power targets and max power sliders(aka, identical stock and max voltage). basically, if you have the same cards in sli.

Thanks for the reply pc-illiterate!

So what would the disadvantage be to leaving the power target and voltage sliders at maximum?
