Title: What is a safe overclock for a Gigabyte HD 7950? Post by: ande85 on April 27, 2013, 12:33:36 PM 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%. Title: Re: What is a safe overclock for a Gigabyte HD 7950? Post by: Yurizhai on April 27, 2013, 12:45:59 PM 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..

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.

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. Title: Re: What is a safe overclock for a Gigabyte HD 7950? Post by: ande85 on April 27, 2013, 01:46:20 PM 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?
