Goodmorning everyone.

 I wanted to share this binning result of 7 CPUs. The lucky one makes 10 minutes of memtest at 780 mhz with 2.5V and -96 on the evaporator.  Post at 810 but no memtest.

 Also ask some questions to those with more specific experience:

@Gumanoid told me that his CPUs have CB at around -40 degrees.  What are the numbers of your experience?

Mine had CB around -100.

Good CPUs should go higher in frequency, but need external PLL - this is one of the many projects I have on hold.

BTW, some people might experience motherboard CB.

PS: I also remember higher the voltage, more unstable it gets, so usually lower voltage is required on cold, however I don't have enough empirical data to confirm it 100%.

Already.  Like that of @Kotori for Slot A

 This could be the answer.
