Regarding 50°C: either your card is not working fully (e.g. because the CPU might be too busy to serve it) or your cooling solution is a bit over-engineered. For your GPU I'd expect a GPU utilization of 85 - 95% running GPU-Grid. If it's significantly below that something is holding your card back. If your cooling is better than usually aimed for by the manufacturer (70 - 80°C).. be happy :)

I don't know what percentage of the graphics card is being used to process units, the EVGA Precision software does not give that information or i have seen. I have a AMD FX-8350 and Boinc Manager configured to use the 87.5 % of the processor cores. The tasks "Long Runs" of GPUGrid end in approximately 11 hours.
Never before i had a GTX 660 graphics card so i don't know if 11 hours are the right thing for what is expected of the graphics card, but I assume that if they are.

Somewhere in the ballpark of 9-11 hours sounds about right.

You can use Precision-X's "Monitoring" button (or, in the settings, the "Monitoring" tab) to show values to monitor (set the Graph checkmark to checked for various things you want to monitor). Then click OK, then click the arrow at the bottom of Precision-X to expand the Performance Log, and then double-click it to see all of the the monitors configured to be shown.

I recommend watching:
- Clock (the current actual Mhz clock of the GPU)
- Temperature (in *C)
- Usage (this is GPU Usage, a primary way to see how hard the GPU is worked)
- Memory Usage (how much GPU VRAM is used)
- Fan Speed (What % the GPU Fan is running)
- Power (Current Power %; remember, limiting this by setting a certain Power Target %, is the main way to limit how hard the GPU will work)
- Power Limit (Indicates if the GPU is currently being limited by a Power Target %)
- Utilization Limit (Indicates if the GPU is currently not boosting because utilization [GPU Usage %] is not consistently high enough to warrant additional boost)

You can also use GPU-Z to monitor those values. The sensors in GPU-Z are a bit easier to view quickly.

I personally have the temperature monitors configured, via Precision-X, to be tray icons, so I can easily see the temperatures of my 3 GPUs :) ... so I immediately know if the temp exceeds the 70*C thermal limit; nobody messes with my Max Boost!

I already have installed the GPU-Z "GPU Load" is 87 %, i see it as a correct value. In the EVGA Precision X i have all the values to monitor enabled, but I don't know where it shows the percentage of use of the GPU.


Thank you for responding.

To show the "Hardware Monitor" window:
- Expand the tray at the bottom of Precision-X by clicking the little downward pointing arrow
- Click the "Performance Log" button, to bring the graphs into view
- Double-click within the graph area
- Use the mouse to hover, to see what the past values were

Here is a picture of my Precision-X Performance Log window, called "Hardware Monitor":

Here's what the main window should look like, when you have the tray graphs visible:

On that image, the 4th graph is the Usage %.

I've already been able to see it, shows a value of use of the GPU from 86% to 88 %, the same as GPU-Z. I had not understood your explanation by problems of language, for that reason couldn't find it. After your last response i've seen.


Thank you for responding.

Ah, so are you good now?

GPU Usage % = GPU Load = GPU Utilization.
All 3 are the same thing.

EMYArg, seem like your GPU is running well! And this temperature is excellent for air cooling. If the GPU fails under such conditions, it was very likely a chip which would have failed early anyway (seldom but not impossible). I wrote about this somewhere in the beginning of this thread.

I am still processing normally. Winter is now beginning, I have to wait until November to begin the warm days of summer, in those days I will know how good is the cooling that i have.


Thanks to all of you for responding. All the doubts that i had are now resolved.

If at 20°C ambient temperature the GPU runs at 50°C it's a good estimate that it will run at 60°C in 30°C ambient temperature. This assumes constant fan speeds, which might not be the case.

Hello

I'm using one of these cases: http://www.sentey.com/en/bx1-4237-v21 although I have 7 fans installed, I have only the 2 side fans working to introduce air and the rear fan working with the top two fans pulling air. One of the top fan does not work and will be replaced in the coming days.
I'm processing with the processor about 2 or 3 degrees of temperature below the graphics card, the processor is cooled by a Coolermaster Gemin II S524.
Also I replaced the original power supply that cabinet had installed by a power supply Sentey 80 + Gold 850 watts.


Thanks to all of you for responding.

You could drop your CPU temps significantly using a better cooler like the Coolermaster Hyper 212 EVO or the Xigmatek SD128264 Aegir.

I use the Xigmatek on my main systems and at full load the core temps are only 17 DegC higher than idle temps on my 1090T's running push/pull fans on it.
