Hi, do you remember my thread? http://www.techpowerup.com/forums/showthread.php?t=158500 @W1zzard, in your post you mention that I should ask AMD on how to do I2C transfers. Could you be more specific on how I should contact AMD about this. Their forums or an e-mail(if so, which one exactly)? The reason I did not do so back then, was because I failed at my attempts at I2C and was unfamiliar with writing drivers(still am, but I am more enthusiastic right now). If you have any additional tips for I2C, those are welcome, too . I know that Windows x64 based machines require signed drivers in order to be executed, but this should not be so for x86, right? And it's likely bypassable for debug/testing purposes. I apologize if I am overstepping myself in my requests. However, anything related to I2C under Windows or GPU VRMs(or GPU sensor related stuff in general) is extremely scarce on the internet right now.
