NOW I HAVE SOME QUESTIONS:
1. Have I to set power limit to 132% to get maximum clocks, or i can get higher clocks with power limit lower than 132 % ??
2. As I saw, changing minimum voltage from 0.987v, cant change anything in clocks, am I right?
3. Are my clocks +120 and +400 good? average? low?
Warning: Spoiler! (Click to show)
I started to overlock acording to guides I found on internet:
FIRST OF ALL I SET UP POWER LIMIT TO 132 %!
SECOND I SET UP FAN SPEED TO 100 %!
THIRD I DIDNT TOUCH MINIMUM VOLTAGE ( IT STAYED 0.987V ) !
these are my maximum clocks:
here are some tests:
unigine heaven 2.5 2324
1. On Power Target:
I've noticed there's a balance with the power target and the actual TDW usage in GPU-Z to figure out how much to apply to be most effective. Even if the game I'm playing under max graphic setting at +132 power target is not requiring such a power target.
Feels like I can achieve a higher stable Core over clock by lowering the power target. Problem with that is trying to find a happy medium among many games where the power target required changes from game to game. I like to have mine set at +125% and raise the Core highest possible and stable.
Right now as I've had my card for only 3 weeks and not trying any memory upgrade as I've found find Core top first and then work on you memory.
2. I've tested running a forced constant at 1.175v but all it did for me was run 4C higher rather than letting dynamic over clocking down volt when not required. Voltage for me always hits 1.175v in any game I play. If you look at GPU-Z 'max'
VDDC you should see your GPU reaching it as well.
3. Everyone's offsets will vary to get the clock your card is capable of but also so does a lot of factory base Core clocks between cards. When you offset +120 / +400 what is your Core & Memory your reaching on that.

1. Why don't you guys run the prefer maximum performance option in the drivers, in order to make cards core clock fixed?
2. Does it really worth to get GTX680 DCII TOP vs some non reference 7970, if you want to play Crysis games mostly, and is the DCII TOP the best non refernce GTX680?
3. What is an average overclock i should expect from the GTX680, i know every card is different but lets say 1250 with boost?
4. Are this cards sensitive to temp like 7970 is when overclocked?
Thanks in advance!
1. I've not noticed much if any difference between either mode to my experience.
2. ASUS DCUII does have a nice cooling system on their non-reference board, which you can find in either brand.
3. I've noticed for the most part lowest 1200 MHz is a decent over clock. My EVGA GTX 680 does max boost clock 1223 MHz stable 24/7. Believe me 25 MHz is nothing in relation to FPS. Anything better is gravy on an already powerful card.
4. One thing both Nvidia & AMD have in common is the 28nm fabrication and how it respond adversely to heat easy.
