~~The GTX 670 Overclocking Master-Guide~~ - Page 285

post #2841 of 3357
For me when I turned up power target to the 120% which my card is supposed to be able to handle with this software from EVGA my GTX 670 eventually was hitting low 70s with Heaven Benchmark whereas when I was using MSI Afterburner I never was hitting 70s and my card was under full load while running MSI Kombustor.

Power target has the card using more power and thus creating more heat ? Yes or no ?
post #2842 of 3357
On my particular card (windforce3) I also set/found my power target at 120-121%. That seems to be the sweet spot for me. I know I can move the power target higher but that would only produce crashes and artifacts in Heaven bench.
1241 MHz is my stable.
I gather that's pretty average.?
post #2843 of 3357
The way i understand the "power target" is that it sets an uppor limit on power usage. If the card starts to need more power than the limit , it will throttle clocks to reduce consumption to stay under the limit. It only comes into play at high power usage levels. Since i've got ample headroom with my PSU, i've push the power target up to 135%, which is more than any game calls for, to avoid any throttling for this reason.

Upping the power target will allow the card to use more power more so than make the card use more power... at least thats how i understand it.

I don't think it has anything to do with the PSU. I have a Seasonic 860 plat which is overkill .
I believe its a combination of your particular overclock max, and what the game settings are at like ultra, and what the game is asking for..

I thought that I had found my power target sweet spot at 119%.
On precision x monitor Ive observed on the most demanding games (like the crysis series and others) 119-120% power usage with my overclock.
At some point in the game I noticed the power usage would spike to 121-122% and the game would crash. So I bumped up my power target a percentage to 120. 121% would be OK but 122,123,124, and so on just kept getting worse.
and I tried 135% and the card would artifact and crash hard within seconds.

I believe if I could over clock my card to 1300 MHz I surly would be able to take advantage of 135% power.

I have to say so far after using EVGA Precision X and following the guide set here for it having my temps go up by 10 to 20 degrees at times vs using MSI Afterburner is quite a shock. I don't see the reason I would keep on using the EVGA software and this guide cuz it hasn't helped me in the least. I will say I will give it one more go but still need the one question I asked answered and that is ....

When increasing Power Target to max recommended for card which for mine is 120 % does that extra 20% increase the temps quite a bit ? I am going to say yes based off what I have seen.
post #2846 of 3357
Maybe a little bit. I remember resetting my fan profile a little more aggressive. Under hard gaming and benching my card stays under 68. Never over 70. The windforce 3 is quieter than most cards too which is nice.

I played with afterburner initially but switched to evga x just because I preferred the interface. Just preference.
There maybe a difference in temp reporting between the 2 apps but I never noticed.
post #2847 of 3357
Hi guys i just wanted to see how my evga 660ti overclock is. smile.gif i know this is the 670 forum but its what the 660ti club links.
ATM i am totally stable with my current settings but im not sure if i can do anything to get a higher overclock.
Currently my core overclocks to about 1175. i really really want to hit 1200+ for some reason :/.

Model: EVGA 660ti reference
boost clock: stock 1082
max boost: overclocked 1188
mem clock: 1752.8
power target: 123%
voltage maxes at 1.175 currently
Also i never go over 70C so i dont get any temp throttling. Also I get no artifacting even at higher clocks just heaven stops responding.

I think they're pretty much the same thing deep down, just slightly different user interfaces on top of the same rivartuner codebase. Although, outside of the core feature set, ab does include a recording function that precx does not.
