Using MSI Afterburner, AMD Wattman, whatever I try, as soon as I apply the new settings they go right back to the previous ones. My -cclock and -mclock parameters in Claymore are having no effect on anything. The weird thing is I have 2 of the exact same card (MSI RX 570 4G) and their settings are different (2000mhz vs 2150mhz memory clock) ... what could have caused this?

How can I regain control over my cards? I have one that is constantly getting incorrect shares so I need to underclock it a bit and I have two or three that could be pushed a little higher.

I've already uninstalled AMD settings so for now it appears Wattman is out of the picture.

Any suggestions? Thanks!

If you eliminated an effect caused by software settings by using DDU, uninstalling MSI AB and AMD drivers then those settings most likely hard-coded in cards BIOS. Do you have a switch for dual BIOS. Change the position, restart the rig and check by GPU-Z. You can modify or re-flash the BIOS from one card to another.

Yes, but those two cards are both using stock BIOS! I just don't understand how one runs at 2000Mhz and one at 2150Mhz no matter what I do with Claymore parameters, Wattool, Afterburner, etc... I basically have no control over the clock speeds of my cards... unless GPU-Z is reporting incorrect information of course...

Did you switch to the second BIOS option? Does GPU-Z show incorrect memory frequency in both windows? Download BIOSes from both cards and open in PE to see the differences.
