Hunting down the HD3000 Artifacts Fix - new clue maybe

[Markus23]

Hi there,

First tried patching AppleIntelSNBGraphicsFB but it didn't worked.
Tried some other suggestions like SMCPing - didn't worked either.

Yesterday I tried a more Hardware-like thing:

In my Bios (Gigabyte GA-H61M-USB3) the Graphics Frequency was locked at 1100Mhz aka Turbo Mode. I entered/switched to 850Mhz (i3 HD3000 Stock Frequency). No Artifacts till now.

Will report back if this constantly working...

Finally, HAPPY END!!!

It seems this thread may now cover audio and graphics. Not sure. But I did try to change my Graphics frequency to 850 and it made no difference.

I have very few graphic artifacts. Some start-ups are bad, some are artifact free. But changing the frequency appears to have made no difference.

Keep up the search. I believe there is a genuine reason for the problem, but I don't believe it has been found yet.

It seems this thread may now cover audio and graphics. Not sure.

It seems the graphics driver is tightly interconnected with audio (maybe cause of hdmi) ...
therefore the research might shift towards audio setup at times ...

Cannot confirm that using toledo's AppleHDA prevents artifacts.
I had to disable KernelCache to have persistent success.
