I have a 'Custom Build (By Apple) - Late 2015' iMac. The specifications are as follows:
Retina 5K 27" Display
4GHz Intel Core i7 μProcessor
32GB 1867MHz DDR3 RAM
AMD radeon R9M395X 4096 MB Graphics
I purchased iStat Menus System Monitoring Software and it came bundled with the Intel Power Gadget software. I installed it because of my 4GHz Intel i7 μProc initially...I didn't think about the GPU at all. After running the software for the first time, I noticed that Power, Frequency, Temperature and Utilization were all functioning, but upon closer inspection I noticed an issue.
On the Frequency Graph, GT is showing 0.00 GHz. After a fair bit of digging online, I found nothing useful. I tried contacting Patrick Konsor directly (BEFORE registering on this site...I am so sorry about that, Patrick)
While I was hoping for a response, I noticed on your website that this software will only display the GPU frequency of Intel variants?
As my graphics card is AMD Radeon, I am assuming that this is why the Frequency GT parameter is reading a constant 0.00 GHz...Am I right in thinking this?
May I ask one other question please...
My Intel Power Gadget version is 3.5.3. I have been through the very minimal settings and there is no "Update" feature...How is the Power gadget updated to a newer version?
