You’ve built a new PC and it’s functioning, but a few problems remain that need attention.

Everything looks reasonable. The CPU clock bars in the lower left are likely indicating active power usage or thermal status. The 96M L3 cache reference matches the Intel 5800X3D specifications. Regarding the USB-C dongle, compatibility issues can arise due to driver updates, cable condition, or PC settings—check your device manager or manufacturer support for details.
It looks like the issue might be related to a display indicator or similar feature. Everything seems in order. AMD confirms it includes 96 MB of L3 cache. Check if your audio drivers and manufacturer-specific software are current.
Activate XMP mode and experiment with increased frequencies starting at 2666, then progress to 3000 MHz and beyond. Possibly the motherboard resists 3200 MHz but supports 3000 MHz; try adjusting accordingly.
Ryzen and compatible boards often face stability problems with particular RAM packages. The default setting of 2133 works when DOCP is off, but not starting it is a common clue for RAM instability. My 5900X setup became unreliable until I realized the importance of QVL. Frequent crashes meant no video during boot, freezing in sleep mode, and similar issues until I moved RAM, GPU, and storage to another board while the unit was being serviced. One DIMM also caused problems, as it didn’t support QVL on that board. My older 1700/B450 system showed inconsistent speeds with the same DIMMs, requiring RMA after a complete shutdown. It’s been a source of frustration, and now I think the issue lies in those DIMMs not being QVL’d for this board. The motherboard doesn’t even accommodate the full capacity. By the way, the replacement kits that fixed these problems on both boards matched their original timing and voltage specs—no timing or power mismatch was involved. Your detailed information would be very useful here.
