Graphics Really not impressed with the 980

There you go.

 

Did that temps still at 80c.

 

Did you click 'apply' after setting the custom fan curve?

I'd manually set the fan speed to 100% with the slider far left, hit apply, then run the benchmark again.

 

Your PCIe bus is set to 1.1. This may be restricting the 980's performance slightly in some games/benchmarks. With a 2500k CPU you should be good for PCIe 2.0. The setting will be in your BIOS somewhere.

 

Seems to be holding around the 60-64 mark.

 

Well - it may ramp up - there's a button somewhere in GPU-Z that brings up a 3D render isn't there - click that and then see what it says? I've not got GPU-Z here and can't remember what to click...

Well - looks like it's getting too hot. What do the benchmark results look like for the Metro/Bioshock/whatever it was, with the fan at full tilt?

 

Oh joy. Will go and look but I am quite rubbish finding my way around the BIOS. Thanks.

 

The 980 is configured to reach 80°C and then stay there using a combination of fan speed and/or clockspeed reduction.

If your 980 is starved of airflow, it seems likely that it's throttling. For an apples to apples comparison I'll run the Metro benchmark later using the same settings, with my clockspeeds at reference, and post the result.

 

This. Although the default fan profile, by my understanding, favours a drop in clock speed over added noise. I wonder if, like our old pal Shirty says, your card is starved of cool air?

 

I cannot see it being starved of airflow as have two 120mm blowing air at it at a fair rate.

 

Otherwise, the TIM might be:

a) badly applied; or
b) not great,

and therefore a cooler re-seat might do the trick?

 

Worth checking, I believe the render test is accessible by clicking the "?".

 

Sorry to be so ignorant. I actually found it and it was doing it's thing, whatever it was so I banged Esc. What was I looking for?

 

Ran Metro: Last Light again and still rubbish.

I've just run that benchmark on my setup which is obviously not the same as yours but according to this my two cards should basically perform the same as your one card on Metro:LL.

I reckon it's a combination of the PCIe Bus thing mentioned above and temperatures keeping your performance down. If you open the EVGA Precision graph does the GPU clock stay constant during the benchmark or does it drop down lower?

 

How would I tell the benchmark is running full screen so how do I see what Precision is doing?

 

When running the render test, have a look to see if the PCIe bus interface as reported by GPUZ changes from "PCIE 2.0 x16 @ x16 1.1" to "PCIE 2.0 x16 @ x16 2.0".

 

Any idea under what sort of heading in the BIOS I will find the PCIe Bus heading?

 

Before you go digging around in the BIOS try running the render test to see if it changes up to 2.0

 

Do the render test and see if it's ramping up automatically first, Kronos.

Edit: beaten to it.
