Well, you first said "Igpu connected to first screen gtx660 to second", so I based my assumptions on that. Didn't mean to discredit your work. Still wondering why this isn't working for anyone except you. Maybe it's the combination of your specific motherboard and iGPU that does the trick. Are...

As stated before, this is exactly what happens with my setup. HD4000 active, ioreg lists it correctly, still glitching. It didn't make any difference whatsoever. You said that your main monitor is connected to the iGPU. It's no surprise to me that in this scenario you wouldn't experience any...

Good to hear! I'm still a bit sceptical, have to see it myself to become a true believer.:lol: Now rolling with iGPU enabled. Getting it to even boot was a nightmare - intelgraphicsfixup saved my day. But even then the procedure was somehow weird. I first needed to disable iGPU, then install...

I can init iGPU first, but it will only activate the iGPU if theres a monitor connected. I pulled down VGA pins 4 and 11 to GND, which seems to do the trick, however, I've just discovered that I can activate "iGPU Multi-Monitor", which enables iGPU regardless of connection. Will try forcing...

Thing is, people already tried that with iGPU, just at the beginning of the thread if I remember correctly. I've yet to test this iGPU trick myself. I was about to when I first discovered this thread, but my mainboard only switches the internal GPU on if there's actually something connected to...

Have been running Base 915, Boost 980, Mem 3004 (values from ref model bios) - glitching after nearly 2 hours of Safari usage, although very lightly and it didn't affect other programs as it previously did. On stock overclocked numbers it would glitch after a couple of minutes, glitching...

Alright, everything went smoothly. Thanks for the detailed instructions! Testing on macOS right now. I chose to only correct memory speed first, since I noticed overclocking it by even a small bit would cause crashes and glitches in games. My hope is to keep the increased GPU clocks while...

Oh well. No risk, no fun. What tools did you use and to how did you clock it (to what frequencies)? Trying to minimize risks.:lol:

Facing the same issues, also running a stock overclocked 660. How would you underclock it? Not so keen on bios editing my card, considering the horrendous prices nowadays... (Thank you, crypto miners:banghead:). I can also confirm this problem existed in earlier versions of macOS, although it...
