Hi ..
i Undervolte my 7800x3d to -40 CO and use Occt to test the stability of All core ( 1 hour of stress extreme ) and the Core cycler ( 5 minutes for each cycle ) after these tests the Cpu seems stable ..
but i have multiple questions ..
1- why the core speed in games is 5050 but in the occt 4600-4500 ?
2- i played cyberpunk and battlefield ( Cpu intensiv games and everything looks fine )
3- i've read alot of comments that -40 is very rare to achieve so is it safe for me after these tests to stick to -40 )
** in Cinebench r23 ( 17900 stock – 18340 undervolte )
thank you
