Hi,

I'm trying to get 1300MHz on core clock. My max core voltage was 1270-1275mV. I'm using the unlocked BIOS 80.04.28.00.3A with 314.07 driver.

The maximum temperature reached was around 85'c on stock cooling.

I was able to get stable on Unigine Heaven Benchmark 4.0 but I'll get crash or artifacts on Crysis 3. So is it that Heaven 4.0 is not stressing enough to test my graphics stability or Crysis 3 just plain sucks?

Just to add up after a few test, on both Heaven benchmark and Crysis 3, sometimes it's another way around.

Every graphics card has different oc capability. Yes, you can pass the heaven benchmark doesn't mean that your gpu is fully stable. Recommended ways are to run the heaven benchmark and directly play heavy games like BF3 and crysis 2/3 to test for gpu stability. Run the game for at least 2 hours to see for any anomalies or artifacts. If there is none, then your gpu is stable. Since the game crashed, you need to lower the core clock until the game runs properly smooth. If reducing core clock done nothing, please reduce the memory clock. You can try to increase voltage, increase the fan speed manually to like 60%, 85C is quite high, dont over 80 degree celcius is recommended. So lower the core clock!

Yea it seems the temperature is an issue too, I will consider a watercooling solution.

I'm still testing the stability with a few games including Max Payne 3 & Far Cry 3. But gaming more than an hour is really pain in the ass due to time restriction.

I'm, able to do 1300/6500 now with 1.28-1.29V for the core voltage. Still testing

New update, I've just re-applied thermal paste & everything and the cards are now running 1300/6500 @ 75'c maximum. Able to stable in Crysis 3 approximately 2 hours.

You know what?....That's great. Hence, dont increase the voltage d...it will increase the heat......is it easy to apply the TIM onto the graphics card die? @@ i never try thou..Mind sharing with me?

Just unscrew everything lol.

What TIM hv u used? Arctic MX4?

Yea Arctic MX4. This one is quite good.

Cool. Mind share a pic of ur rig? Haha ur specs seem so tempting!

I have reverted my gpu core speed to 1293 MHz. Can't get stable on Unigine Heaven 4.0 at 1306 MHz

Now I'm stable at 1293 MHz on Heaven 4.0 for 30 minutes & no games have crashed.

I will upload a picture later Currently backing up my phone pictures.

Good, sometimes when your gpu is stable with the heaven unigine test doesnt mean it is fully stable. Games like BF3, Crysis 3 are still important for us to fully test the gpu stability. Playing those games like 2 hours are enough to test it. Glad to hear that yours is stable at that clock.

Nice Maximus V Formula...Sli somemore...u really rich hahahahha

Whoa....nice rig Vigilant!

wow sli 680. really good.

in my opinion if you want to reach 1300 mhz you need 1.3vcore and also water block for gpu.
