yeah I did.

I don't know for sure. What is the cpu?

I know any mobos that uses celeron g3900 or newer should work.  The oldest cpus I have now are the g3900 they work with 3000

series.

I even have some mobos that use ddr3 ram with celeron g3900 they are fine. if you keep them all the same.

3060ti up to 4 tested and work
3070ti up to 3 tested and work
3080   up to 3 tested and work on the 6 slot onda clones

If I could cool them I think they would do more.

I also have a buddy with some 12 slot boards running 11x 3070's with g3900 cpu and 1600 speed ddr3 ram
