Help with HD3000 on Mojave

Hello everyone,

I have trouble installing my HD3000 on Mojave.

I found a package of kext files on the internet. I install them with KextBeast. Once installed, I reboot the computer. The computer reboot itself twice and then load MacOS Mojave.

My chipset is now recognize as HD3000 512mb.

The problem occurs when I reboot or shutdown the computer after that initial boot. Sometimes it's still recognized as HD3000 512mb but most of the time it is recognized as HD3000 7mb.

Can you help me to keep my 512mb everytime I boot the computer ?

Technical infos:

Cpu : i7 2600k Motherboard: P8Z77-v lx

Thank you a lot for your help :)
