Anyways back on toppic i have a rx 480 rig all 8gb , everytime i change the settings in wattman i notice they revert back
and sometimes crash even, another thing i found is turning the power limits below neg 15 reduced my hashrate by alot so i cant do that.
I noticed sometimes the wattman settings get funky when tweaking, so I have to reset the settings back to default everytime when I want to create a new config and also restart the computer. Give that a try.
Also, I noticed when I try to change wattman settings on the fly while mining, it goes wack, so I only change it when not mining and then do a full computer restart.
If you want to lower your memory clock to 1750, you need to flash your 8gb to 4gb bios because the 8gb bios is locked at 2000 mhz for the lowest memory clock in wattman from what I can see.
Edit: Plus, there was no need for that 8gb for eth for now, so I figured it should save some power by the bios disabling 4gb and having the memory clock to 1750 instead of 2000 mhz.
