Same here, 2450 bbse 8-10-7 unstable, even 8-12-8 not exact.
Samsung 2709mhz 9-12-12 pass but took 2v lol and was verrry slow, seems 2600 divider is 2 seconds behind 2400 and some bclk on my end.
Vaseline is fine on the mpower just dont put the VRM cooler back on, that thing is an ice magnet. Run it raw no protection baby
EDIT:
Getting stronger, just cant give up
