iMac mid 2011 & K4100m

[Anoxym]

Hi,

I have a mid 2011 iMac upgraded with

- K4100M Quadro NVIDIA graphic card (Flashed by nikey22)
- 16Go RAM
- i5 3.1Ghz
- 250Go SSD
- 1.5To

I have successfully installed Ventura on it with OCLP in last version and everything works fine.

But after couple days, freeze appear, the Mac doesn’t respond and stay on the loading bar with screen bugs.

I have installed the patch on drive and tried to restart on the usb key but doesn’t work.

The freeze appear randomly and I think it’s because of the graphics card.

Have you any advice ?

Thanks,
Regards
