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.  ------------- AMD Ryzen 1700 *F4-3000C15D-16GTZ *Asrock X370 Taichi *600W Thermaltake TR2 80+ Gold *FD Define R5 *RX 480 HIS IceQ X2 Roaring OC 8Gb *FD Kellvin s24 |

" rel="nofollow - 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 ------------- [url=https://valid.x86.fr/jpg250]  [/url]3800X, powercolor reddevil vega64, gskill tridentz3866, taichix370, evga750watt gold |

no global c states don't cause this problem. It's a bug of AGESA, in 4.40 UEFI problem solved. ------------- AMD Ryzen 1700 *F4-3000C15D-16GTZ *Asrock X370 Taichi *600W Thermaltake TR2 80+ Gold *FD Define R5 *RX 480 HIS IceQ X2 Roaring OC 8Gb *FD Kellvin s24 |
