Nope it actually improved, reason being lower temps under load. From what I've seen with these Zen 2 chips, when running stock or PBO there is minute changes in core speed under load and these changes are impacted by core temp.

Why lowering the voltage would reduce the performance??
Less voltage->less heat->better clocks->better performance

ppt 1000
tdc 105
edc 90
scalar x10
+100 mhz
llc8 (lower)
and 1usmus power plan (it helped me to get 4450mhz at single core)
Hi, i tried with scalar x10 but the Vcore for ST and MT apps/bench is very high I think It's too much for everiday use.
If I set scalar x3 with LLC8 durign MT Cpuz bench I reach 1,35/1,36v :-\
