5.2.6 CPU_VDDR12 Fail
Example: AMD_AM3
MA790FXT-UD5P identified by:
01. Post code C1 and reset.
02. Impedance measure of FB16 is 9ohm.
(The impedance of FB16 is around 0ohm.)
.Signal Explanation:
CPU_VDDR12 provide the voltage to CPU VDDR.
VDDR is the power for CPU memory bus.
FB16 is voltage protection for DDR bus, so is very easy to
Burn out.
