Topic: What is a safe overclock for a Gigabyte HD 7950? (Read 2801 times)
As a test I increased the GPU to 1200, and decreased the fan to 70%. The resulting temperature was 77 (before I changed everything I think it was around 75). I now have the fan at 80%, and the temperature has lowered to 75. Basically, for increased longevity (I would like the leave the GPU overclocked by 20%), would it be better to leave the fan at 70% or 80%? I'm thinking 70% because an extra 3.6F shouldn't be that major, should it?
Well looks really Nice! For safety purposes of temp. I run my mining rig (2x Radeon 7950) under the following conditions:
- GPU: 1050 MHz.
- Memory: 1250 MHz.
- Fans: 60%
Temperatures range is between 69-73 degrees Celcius.
- GPU: 1050 MHz.
- Memory: 1250 MHz.
- Fans: 60%
Temperatures range is between 69-73 degrees Celcius.
73C° seems safe for me, my HD5770 at full charge is at 80-85C° and my HD4850 can go up to 110-115C° (it's mono slot) but only 90-95°C when mining.
The problem is your fan because above 85% of it's full speed, it's durability might significantly shorten.
So it should be better to reduce the fan speed to 85% and see the new temperature.

It's probably fine. Seems to me cards are built to fucking last. Used to have my last card mining at 92C, it's idle temp was like 70C. Lasted 2 years before I sold it on ebay. I still dream about her, wonder if she's still alive..
I'm trying to maximize performance + longevity for my card. I'm using the easy boost utility, because yes, I will destroy the thing the minute I start playing around with voltages (no overclocking experience). Right now here at the current results for my setup.
GPU: 1175
Memory: 1250
Temperature: 73
Fan speed: 95
Is this safe? Usually at stock the temperature is 69-71, and the fan is at 90%.
