So, do I want the KB number to be lower or higher. If it means what I think it means, it's that a lower KB means that you have manually tuned the card better. I could be horribly horribly wrong though. Anyway, another question, after a pc restart all my oc settings are saved except for the voltage, any clue as to why?

If you have to ask you didn't read the guide very well. wink.gif

KB is Keplar Boost. It is set in stone for each card and set that way from the factory. Under 3D load your card will clock as high as the base freq + boost freq + KB to get to it's max boost (if conditions are right) . A higher KB typically means your card can OC higher, but not always. It's still a lottery as to how good your GPU is.

It looks like your base clock is 1006MHz, your boost clock is 1085MHz or +79MHz, and your KB is 1167 or +82MHz. You have added 100MHz to all these freq with your changes in PX. I didn't think your max boost would appear in PX, though. Not really sure...I'm using Asus GPU Tweak. And I thought KB had to be a multiple of 13MHz, so that is also a little weird.

Maybe someone else more familiar with PX knows and can chime in.

Read the full guide again. Hopefully, it will start to make more sense. It doesn't sound like you understand everything yet.

As for the voltage, that is just the way PX works. The voltage option is actually a separate program that just has a shortcut in the PX interface.

I definitely do not understand everything yet, as overclocking seems more ork than it used to be, just trying to get the most out of my card

Let me know exactly which parts of the guide you don't understand and I'll try to make them more clear. wink.gif

It looks like you are off to a great start, though! If you want even more you'll most likely have to try flashing a BIOS that allows higher voltage.

Getting tired of these new drivers really fast... +137 would give me 1330, but now it gives me 1332 which is unstable.. and since the new drivers overclock in increments of 13, Its either 1332(which crashes) or 1319, which is just stupid when I can do more.

I'm just used to overclocking the way it was with my 480s

This is pretty new to me too. I've only had this card a few weeks.

Previous cards are 450, 280, 8800GTS-512. Also 4850 on ATI.

It's a little challenging at first, but I actually like the way you have to watch the monitor to make sure your OC is actually staying peaked. Getting those dips to level off is priceless! biggrin.gif

+1. This is why I'm still running 306.23

So, I think I am at the max I can push my 670 FTW, whenever I seem to increase any of the values beyond what I have saved when I do the Heaven benchmark I get some jacked up results. One run I made it to test #26 of 26 before the screen blacked out on me.
