W1zzard, you once told me that if I wanted to obtain datasheets on AMD/Nvidia's temperature sensors I'd need to sign an NDA. Back then I did some research and didn't find a way to do it. So now I decided to ask you how I can do this since when I contacted Sapphire's support team they told me...

It's possible it might not be a bug. According to a guy that works with AMD, different OEMs may change stuff on the PCB resulting in code that might work for a XXX card in general but not for Sapphire,Xfx etc. I am not as experienced with I2C as W1zzard, but I have had my fair share of it...

Just wanted to post back that I was able to do what I wanted. I can successfully obtain VRM temps. It's thanks to the Linux source code that I was able to do it(albeit GPL'ed code). Took a while to figure out how to map memory to userspace, but I also did that thanks PhyMem on CodeProject...

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 program is called radeonvolt. It's opensource https://github.com/ius/radeonvolt. It supports a small range of cards, the 58xx series only, but it is a nice proof of concept. It also does not require any external driver at all due to how linux works(quite amazing). I've already compiled...

I found an existing implementation which to use to query VRMs, however it is linux specific. In windows I must map the PCI bus memory to userspace which from what I am reading is much harder in Windows 7. Let's hope \Device\PhysicalMemory will work. Also, your executable is a single file...

I am new here, however I wanted to ask the author of GPU-Z if it is possible to expose some code of how he accesses the VRM temps of a Graphics card or otherwise tell me how one can fetch them. The AMD ADL library does not expose any wrapper to fetch the temps, thus only software like this have...
