meankeys my friend you are anything but a rookie, clocks and clocks per volt depends what your doing or benching, 4.5 at 1.25v, 4.9 for 3D benching at 1.28v, non delidded. I haven't tested stability except to get through a bench run as my plan is to turn around and sell the chip, and the Titan V asap
Obviously I am keeping the R6A, what a sweet board, the X Apex and a 8700K is a real performer
Merry Christmas to you and your family and a happy and prosperous new year
