On the 4x32GB kit, 3200MHz seems to be the upper bounds of stability. Even though we have similar system specs, I am unable to get stable memory benchmarks in memtest at 3600MHz or 3733MHz. It will also randomly BSOD.
I was expecting your scores at 3600MHz+ to be higher than the results I'm getting at 3200MHz. However, I am getting Cinebench R20 scores that are similar to yours even though my memory is slower (3200MHz). If I enable PBO in Ryzen Master, CBR20 reaches 9440 pts.
Were you able to do a full pass of memtest without errors at 3733MHz ?
