New Build - Error 0d and power cut - Taichi x470

0d is on low level initialisation, main hardware powering up (cpu, chipset, ...)

try to unplug everything you can, also check your cpu for bent pins

try another psu

and a reset cmos is ...................

unplug the power lead from psu and flip out the button battery for 10 mins

it tends to actually work much better than the cmos reset button

okay i did more proper google search now

AMD has their own DRAM recovery mechanism that automatically lowers the DRAM Ratio and resets timings if DRAM training fails (F9 - 0d) during early POST). If you reset at this point you might get stuck at CF or 90 POST codes, manually reset again and the system should POST with the lower ratio and default timings. AMD CBS settings are also reset when this happens.

so 0d is when RAM cant be trained

put that stick on right side, thats the most compatible one

also do u get F9 before 0d?

always worth trying the other pcie slot

and........ not a usual problem but i have one gpu here that is a beech ! to seat properly

if i try and srew it into case it pulls it out of the pcie slot, might be worth checking
