@Pacha, it won't be an issue caused by the SSD. It is more likely to be an issue with how your Vega 64 is initiated, as the GFX card is not getting reinitialised after sleep.
It could also be an issue with how sleep/hibernation is setup on your hack. I would suggest you try out the following Terminal commands to disable Hibernation and fix other Sleep/hibernation issues:
Disable Hibernation
Hibernation (suspend to disk or S4 sleep) is not supported on hackintosh.
You should disable it with the following terminal commands:
Code:
sudo pmset -a hibernatemode 0
sudo rm /var/vm/sleepimage
sudo mkdir /var/vm/sleepimage
Always check your hibernatemode after updates and disable it. System updates tend to re-enable it, although the trick above (making sleepimage a directory) tends to help.
And it may be a good idea to disable the other hibernation related options:
Code:
sudo pmset -a standby 0
sudo pmset -a autopoweroff 0
See if that helps.
If this doesn't help can you attache a copy of your CLOVER folder and I will look and see if any other tweaks are required regarding the Vega 64.
