It looks like the -strap command in Claymore is not being applied since both of the views in the AMDMemTweak tool seem to show the same data. So even though he's reporting that the strap was successful, the AMDMemTweak tool seems to show that it was not. Which is why you're not getting a reasonable hash rate ... you're getting the same for both no -strap and -strap 1.
What version of Windows are you on? I've had trouble with Win10 release 1903 similar to this.
