Nice to see you here. I am not so sure how it works. Can you look in gpu-z which memory voltage value you see when idling and stressing?
Sure, voltages when stressed(using GPU-Z 0.38) is 1.15V(VDDCI reports that) and during idle it's also 1.15V. Vcore is 1.1625Vcore during load, and when trying to idle it's 1.0625V or 1.1625V as the card keeps switching between 400Mhz and 850Mhz. Most likely due to my dual display setup
Also nice to see Astennu reports the same voltages as me, so it's common
Will try to get the card to 157/400 clocks during low 2D power play to see what the card will do in terms of voltages, as 0x18 and 0x15 are still valid options. Vcore of 1.1625 could be 1.15 or 1.175 in the BIOS
[EDIT]
Alright, 2D low power clocks are indeed 1.0625Vcore and 1.1Vmem on 157/400 Mhz.
So that means that 0x17 is for 2D idle on Vcore and 0x16 for 2D Idle Vmem.....
Hmm, very odd, or shouldn't we lock at these registers as linked? That might solve the "issue" of not beeing able of linking GPU registers with Memory registers!
