hello there rme crew

ive been the lucky owner of a RME fireface ufx ll for a few months now and things have never sounded better.
i do have some buffering, pop and clicks every now and then that forces me to restart my system (pc & ufx ll).

this happens while working in my reaper soft but also when playing audio from youtube, vlc player or winamp (yes still using that) so all audio basically.
if i turn only the ufx off and on the prob is gone but will come back after 10 min or not at all, it appears random.

this was fine for a while but it really kills my flow now and would like to find a solution.
i did search many times for a solution but audio interface jargon and my lack of knowledge keeps me from solving it i guess.

so far i think it might be usb 2.0 / 3.0 related, the ufx having usb 2.0, my motherboard mostly 3.0.
according to the manual i have the ufx usb plugged now in one of the only 2 usb 2.0 sockets but its still happening.

im on PC windows 10 64b
rampage v extreme motherboard ( https://www.asus.com/us/Motherboards/RAMPAGE_V_EXTREME/ )

fireface ufx ll, all drivers updated (although my ufx shows up as a madi-device) but i think that's normal since they said that you have to install the madi drivers for the rme fireface ufx ll if i remember correctly.

what else can i do to try to solve this problem once and for all?

many thanks..
