Crush Posted January 17, 2008 Report Share Posted January 17, 2008 Ok, here goes. I've been having a huge problem with my GPU for a long time. I hope someone can help. The problem lies in the temperature sensing and monitoring, and how different drivers handle it. I use the i8kfangui to monitor my GPU temperature. I've found that it is the most accurate of all, and it can adjust the temperature if needed. Why adjust? The reported temperature is always 8 degrees lower than it actually is. So, if i8k reports 49, the GPU is actually running at 57. So I just add the 8 degree offset and always get the correct temperature. ATItool temperature monitoring is different. It varies depending on the driver. For example, for the 165.01 atitool would report 57. But for the 167.51 beta and 169.09 it would report 49. The thing is that the GPU's speed throttling and overheat threshold is done according to the atitool temperature. Downclock threshold for my GPU is set to 102 degrees. I can't change that. With the 165.01 driver, when the temp reaches 102 (both i8k and atitool report the same), the speed is throttled down to prevent overheating and all is well. But with the 169.09, the GPU thinks it's running at 94, while it's actually running at 102, and eventually overheats and shuts down the PC. Now I can't understand why different drivers would report the temp differently. It's a software problem. So it should be possible to change it somewhere in the driver. I want to use the 167.51 beta driver, which is supposed to be made especially for my laptop and card, but I can't because it incorrectly reports the temp, and in a hot environment the GPU can reach the 102 degree threshold when gaming. I need to make all the drivers report the right temperature. This is really pissing me off. Please help... :) Quote Link to comment Share on other sites More sharing options...
