7870 hawk profile works great. Monitoring output shows different than dmm, but not a big deal

 

Did some more testing. It seems that vgpu can only go up to 1.5v. With 1.5v on evc set, it shows 1.488v on dmm at idle. Under load it drops a lot. vmem is in fact pll. The pll setting does nothing.

 

When applying trying to apply over 1.5v vgpu, it doesn't apply any more and eventually crashes evc drivers. It will show in corner as device not connected and even in device manager it does not show up anymore.

Did anyone notice that CHL8318 and ASP1212 are exactly the same? ASP1212 is on 780Ti DC2 for example. Think they just rebranded it.

Compare the datasheets:

So the ASP1212 should be already working with a CHL8318 profile (or at least be very easily to add ;)) right?

I just tried this on the 780 lightning profile and 680/770 profile and it does not work for me with 780Ti DC2.

 

This is what scanning the card shows.

No worries, easy mistake. I believe there's no digital control available for vmem/pll, there's another chip but I'm not sure what it's for. You could try this to get some data:

 

Go to Menu and select Register scan. Enter:

 

Device address 0x0C

Register start 0x1

Register end 0xFF

 

Run it and send the log to me.

I got some reports that there's a maximum voltage limit using some VT1165 controllers, not sure how to change that. I'll look into it and get back to you.
