I've tried to enable MSI afterburner unofficial overclocking to get it work as 300 but minimum i see is 600. Any ideas?
Could you try:
- Set memory speed to 600
- Apply
- Switch to display other card
- Switch back
- Now you can select 300
A little weird, but works for me.
The other option is to set it to 600, close MSI Afterburner and reopen it, then you can set it to 300. if you want to go lower still , you have to close it and open it again. I have multiple GPUs and set each card to 600 before closing it, etc.
