Wierd behavior after overclock (x370 killer sli)

Mind you I have tested 3.8 at 1.3v on AIDA for 30 min and Prime for another 30min and it was stable I also ran Cinebench 5 times in a row still no crash.

Do you have, in the UEFI, OC Tweaker screen, the AM4 Advance(d) Boot Training option enabled (Auto)?

If so, set it to disabled.

That could be related to your memory OC, if you have a memory OC.

A VCore of 1.3V is a bit low for 3.8GHz+, unless you have a very good CPU. Hopefully the 1.3V from AIDA64 (I assume) is not the VID. What is the VCore set to in the UEFI, and what VCore mode are you using?

I have the same board, with a 1700X at 3.925GHz, and don't have that behavior.

overclocking on auto voltage isnt really the done thing

in practice its better to use a fixed/set voltage that is known to work stable with most cpus at that speed ,and then test/try to lower it down gradually as far as your own actual cpu will remain stable


HAVING SAID THAT...that theory was blown out the window last weekend when i asisted my friend overclock his ryzen and it jumped directly into a dead lock at established safe 3.8ghz clock and fixed volts..................yet has remained perfectly super reliable when we just set 3.8 on the slider and left every other dam setting at auto......go figure ryzen !
