Let me put it to you this way. When testers review the 680 or 670, you have to take into consideration what MHz it peaks at. One 680 might OC stock over 1200, while another might OC low 1100's (boost clock). And same thing with the 670. My 680 boosted to 1150 stock, while my 670 went to 1215, and the framerates remain pretty identical. In 3Dmark 11, for example the 680 OC'd to 1250 had 3-6 fp/s on the 670 even though I had the 670 OC to 1250 also. So the extra shader processors do help the 680 a bit. You'll see this time and time again in benchmarks. But if you own a 680 that will only reach 1150 for example vs a 670 with 1350, then yes, the 670 in this example will beat the 680.

Ah, that makes sense! Thanks for the info.

nope , its in neweggs return policy. I think one of the actual phrases you can select is "not satisfied with product" or something

it was , but for the fee i got to play with it for almost a month before i decided i didn't like it.



I just would feel like a douche calling them up and telling them its defective and i want my money back when its not true. especially if its just a bad overclocker or something like that. you arent guaranteed an overclock.

Hi Guys,

I played BF3 for several hours and BF3 quit on me few times, I had to lower memory to +200. First to +600 (from +700) and then to +200... so I guess I have to find sweet spot between +200 and +600.

I'm posting shots from AB software showing more info. Maybe tomorrow I will try to reseat GPU and apply mx-4 paste...

Yes, my card is very poor overclocker.... redface.gif

glad you finally posted those screenshots so i can help you thumb.gif

First thing i notice is your GPU usage is all over the place. Were those screenshots from BF3? Usually when i play a demanding game or run a benchmark my GPU usage is pegged at 90%-100% and yours is constantly going from 50% to 100% and even running at 50-60% for a long period of time. This makes me think something else is holding back your GPU which would make the kepler GPU throttle down to save power since any additional GPU usage would be useless with a bottleneck. Can you set your memory to stock speeds (+0) and your core clock to +70 and then run Heaven benchmark with maxed settings and then post a set of screenshots like you did above? That way i can tell if it's the game causing those GPU usage spikes and the low GPU usage in general or a bottleneck in your system.

Also, your power percent is only at 40% and maxing at 64% and your temperatures are maxing at only 65 (and fan speed only at 44%) so there's no reason for the card to not be running at a much higher boost. There's no variables here holding it back EXCEPT if the card is being throttled for the reasons i described in the first paragraph.

You might also want to try dropping your power percent to 100%. Jacking it to the max can sometimes cause boost throttling and instability. Also, you could try using Precision X instead of AB and then set the voltage to 1.175, that will give you an additional .01V compared to AB.

So here's what you should do for now:
  • Get Precision X and set voltage to 1.175
  • Set Power Percent to 100% (default)
  • Set your fan to run at 60% constantly (you can set this back to auto after the Heaven run)
  • Increase your core clock by +70
  • Leave your memory at default (+0)
  • Run Heaven with max settings and then screenshot the graphs just like you did here so i can look at those.

You can revert back to your original AB settings after this if you wish, i just need to see that info to be sure it's your GPU and not improper settings or a bottleneck causing it to throttle.

then i guess i just got bad luck.

anyway, will try 50%-60% fan setting so temp wont go up to 70C and throttle performance

your clock in that screenshot maxed at 1236, how is that bad luck? seems pretty good to me.
post #1209 of 1506
thanks so much for trying to help me.

Yes it was after playing bf3. Maybe we see the spike because i forced adaptive vsync in BF3, hence gpu is not using 100% of its power... It tries to stay at 60FPS. I'm just guessing here.... I will do more testing tonight. I'm leaving for work and I did Heaven with AB, I will try precision x tonight with voltage adjustment as per your instructions...

according to this thread, 1236 is below average
