X370 Taichi voltage issue

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

Hello people, I need advice. My mobo UEFI version is 3.2. I have the 
following problem. I set the voltage and frequency of the processor in 
p-state overclock section. More precisely I change there only FID and 
further on the first page UEFI set Vcore LLC1. From this place I will 
try to describe in the most detail my problem.

I set LLC1 and boot the system. Next, I monitor the sensor CPU core 
voltage (SVI2 TFN), which displays the voltage directly on the 
processor. Immediately after loading system with the set VID at the 
standard value (3A=1.1875V), I see on the sensor 1.219V under load. But 
If the computer is carried through the sleep mode - the voltage values 
on the sensor change radically from 1.219V to 1.175V. Then, if you turn 
off the computer for more than 10 minutes, after turning on the value 
back on, it returns to 1.219V.

I have carried out these manipulations many times. And each time the 
values are repeated exactly. What is this: a defect in motherboard (so I
 need RMA procedure) or a UEFI error/bug?

This is an abnormal behavior, since the values should not change so much, especially in what is the meaning of the LLC mode?

Here are screnshots with voltage monitoring, the second picture shows 
the moment when the computer goes into sleep and awakening mode.

	do you still have global c states enabled ? if so this may well explain the downvolt mine does it ,and its expected ,i have no system instability though

	no global c states don't cause this problem. It's a bug of AGESA, in 4.40 UEFI problem solved.
