I have 4 sticks of CMT32GX5M2X6000C36.  When I turn XMP 1 or 2 on with all 4 sticks installed, I get memtest86 errors out the wazoo.  This is with default BIOS settings on 1202, enabling just the XMP.  If I pull two sticks, I can run XMP1 with no err...

I've had this system up and running for 2-3 weeks.  I finally pulled a decent speaker out and plugged in into the 3.5LR jack.  It works, but there is a delay of almost a second.  This is on YouTube on Chrome, Brave, and Edge.  No difference anywhere....
