Hi folks,

 

I'm having trouble to overclock my GTX660ti...and wonder if you guys can help me ;)

Im a noob in GPU overclocking btw.. :D

 

To overclock the card i use MSI Afterburner.

For Stresstest im using Kombustor and theValley Benchmark..

 

So i've found some theards wich show how to overcklock the card..

And i tried the settings that Linus uses in his Benchmark videos..

 

The problem is everytime i try to overclock the card and run Kombustor the "OpenGL" Graphics card driver stos working...

 

So this is one of the overcklocks i tried:

Please Help me, i know im a noob, but i really want to overclock this card, because everyone says that this paticular card is a overcklocking beast?!

max out core voltage should help and in the setting unlock triple overvoltage to overclock ram

Thanks for the quick answer..

 

Should i max out memory and Aux voltage too?

 

What would be a good overclock for this card?

That'll increase temps badly though.

Be sure to overclock incrementally.

first find a stable core clock then you go for the ram, the overvoltage are just tools to help the stability of the card 

this is time consuming... it took me about 4 days to overclock my 660ti to be stable 

and all cards are diffrent

i know but if you are overclocking 1 of these , it isnt that bad, it has a tf4 cooler

While every GPU will vary slightly(even if same model), I've been able to achieve a 1.2GHz overclock on my 660 Ti from ASUS. It's the Direct CUII card. Also, I didn't even have to adjust voltage. As Austin said, overclock incrementally by about 10-20MHz, stress testing every time, either with a game or a benchmarking tool like the Heaven or Valley benchmark.

Also, for reference, these are my current adjustments.

So i tried this overclock..

 

Same problem , Open Gl lost connection after 30 sec. kombustor testing..

 

could it be that i have a bad card?

At least for overclocking. Unfortunately, you cannot RMA the card because it cannot overclock. Looks like your GPU lost the silicon lottery.

I know that...

Maybe there is another way to RMA it...

Lemme run Kombuster and see what happens. What are your ambient temps?

Room temperatures. Also, I ran Kombuster, and I hit 55ish degrees C. Try bumping up your fans a bit.

So room temperature is 21 degrees C.

I do not thinks the fans are the problem, because i have a very well ventilatet case..

I'm afraid you have a bad card for overclocking.

So i bumped up the fans of the card manually, and it seems to be stable at 1.2 Ghz Core Clock...

Now the ram is in progress..

Thanks for your help!
