Clear CMOS Problem X370 , B350 , X470 , B450 , X570 , B550

- The cause in which clear CMOS fails -
A turbo boost of Ryzen 2700X is set as 4.3GHz. But when using 4.2GHz, more than 1.40 V is needed.
When it was an error using Ryzen, BIOS tries to set CMOS as default.
When starting, the problem tries to start by 4.2GHz of Ryzen 2700X or 4.0GHz by all CPU.
” This is the pressure of Intel. ”
Ryzen BIOS have the problem that clear CMOS fails from BIOS of Ryzen 1000 series.

- Avoidance method -
BIOS of a Ryzen series uses established CPU clock and CPU voltage in taking.
When establishing the numerical value of the CPU clock, start failure can be evaded.
When making the CPU clock AUTO, after Ryzen made an error, it can't start any more by the motherboard.

- The cause lacking in the voltage -
The voltage of the CPU core will be the numerical value which reduced the numerical value of Offset from Vcore.
An offset of 0,10V is set as an X model of Ryzen compulsorily.
An offset of 0,0375V is set as a normal model of Ryzen compulsorily.
When setting of default was 4.0GHz, it can't start because it's lacking in the voltage.
When setting of default was 4.2Ghz, it's always lacking in the voltage, so it can't start.
” This is the pressure of Intel. ”

That the thing as which a turbo boost of AMD is set subject to the 1.45V and the CPU clock by which AMD is an exception are indicated on a specification seat and that Offset is too high in voltage
BIOS abused the 3 points by the pressure of Intel.
The computer which could be used, it's impossible to use it, doing is prohibited by law.
It's possible to do a class suit.

- The Way to Clear CMOS -
1. A pin of clear CMOS is turned on.
2. A battery is removed.
3 After turning off PSU, the electric power of the motherboard is OFF by a power supply button.
4. After removing a battery, connect battery outer case.
5 It's left.

Anyway unless CMOS volatilizes, CMOS isn't reset.
Other plan to avoid is only the model who cuts it with a BIOS update only by a motherboard.
When doing a BIOS update only by a motherboard, please remove everything of CPU, RAM, VGA, SATA, NVMe, USB and Fan.

A motherboard was a boot by BIOS of Ryzen, and the cause which isn't put on was specified.
It's a defect.
A performance boost is MOD. The Offset voltage isn't changed and the Offset voltage is added.
Only the voltage isn't reset in clear CMOS.
BIOS of Ryzen specified its cause which fails in a boot. It's a defect.
--------

A performance boost is MOD.
It increases without the Offset voltage's being changed.

For example
Base Offset 0.0375V
Performance boost Offset 0.10V
A performance boost is MOD.
When turning on a performance boost, Offset is 0.0375V+0.10V.
The defect occurs.

When Ryzen 1700 is 3.5GHz, the voltage is 1.0750V. When Ryzen 1500X was 3,5Ghz and 1.200V, I don't come to the 1500X by a boot.
The evidence that Offset occurs beyond 0.10V.

When BIOS was default, a performance boost becomes on.
But the voltage isn't reset." That's the pressure of Intel".

When the voltage is added to a CPU clock, after a computer made an error, BIOS initializes CMOS.
A performance boost becomes on with that. The Offset voltage will be 0.13750V.
CPU run out of the voltage, so a boot can't be done.

" This is the pressure of Intel".

1. You aren't supposed to make the CPU clock AUTO. A motherboard is the biggest clock of TB, and a boot is done and done (1.40V).
2 There is a Offset bug of the performance boost. You have to establish the voltage highly 0.15 V.
Ryzen 1700 3.5Ghz 1.225V
Ryzen 1600AF 3.8GHz 1.250V
Ryzen 3600 0ffset -0.10V 4.0GHz
Ryzen 4600 Offset -0.10V 4.2Ghz

That the motherboard can set Offset and Vcore, Offset comes and is-0.05V.
And Auto CMOS A reset is "on". That resets the voltage, the possible only function. When that becomes off, the voltage isn't reset.

" The all is the pressure of Intel".

The act which gives disadvantage to a consumer is prohibited.
This is common sense.


● The problem that a motherboard is failed in Boot
● The problem that the voltage isn't reset in clear CMOS
● The problem Offset of a TB boost is an abnormally too high thing, and that CMOS disintegrates itself
● The problem that CMOS isn't reset though a battery was removed

Give disadvantage to a partner by the flaw = flaw.
(The all is the pressure of Intel.)

On it.
The effect reach of the bug is slight but makes the function of the system cause the trouble I don't have. And don't be possible to repair the bug promptly.

(When or the bug is numerous remarkably, and moreover a trouble is manifested in sequence, and occurs to operation of a system.).
It has to be called something defective in a program.".
As the case when even size revelation and the bug can be a flaw.

(1) The trouble which gives it to the system function is slight but is not.
(2) It can't be repaired, or, the bug of a lot is manifested in sequence, and a system can't work.

Even if the bug is found after delivery.
The bugs are repairs promptly, we assume that there is a flaw in a program when corresponding, and it can be said that a possibility that claims for damages are admitted is very low.
On the other hand because a flaw and an estimated possibility rise when the bug doesn't form for a repair promptly.
The necessity to negotiate for future's processing carefully is forming between the order person.

⇒ The conduct which doesn't handle and discharges harm though a manufacturer knows
⇒ For that to violate the consumer protection (as common sense) in a juror trial.
⇒ The side where a class suit was done is fixation, and I win the case.
(Amazon is for the partner of an agency who puts damage of the cost it required in the bad correspondence on trial.)

The Offset voltage is changed to 0.1250V by BIOS of Ryzen. The cause of its bug and a mechanism were specified.

-Offset problem -
Basic : 0,0250V << Probably.
XFR: 0.0500V
TB: 0.0500V
Question) Why is Offset changed to 0.025+0.05+0,05 = 0.125V?
1) Vcore and 2) Base Offset 3) TB and 4) XFR
That's a principle of the program mistake added up:.
MOD which makes "P0 State" that.
But because the voltage is input double, 2.5V hangs.
There is a voltage limiter, so the voltage it doesn't take for that is corrected automatically.
⇒ That's the numerical value remains bug of the "power" in an equipped exchange "defense" (It's the bug work which occurs in SFC: GADYURIN.)
⇒ It's exchanged for Excalibur after an equipped exchange is removed once when it's original.
⇒ When exchanging it directly without removing a weapon, because you don't return it to the beginning, a parameter will be power 50 + weapon 166 + weapon 166 (Power increases in 380.)
In case of a TB boost program
(X) the way to change for that is impossible as a program.
(◎) It's a way right to increase after it's returned to the original numerical value.
Without returning the numerical value, TB and XFR change the numerical value just as it is, it's developed into the numerical value remains bug by the thing you (have added).
Offset is the mechanism added up.
One with an X does an X nothingness, and lay is also the trick to need the voltage wastefully 0.05 V (It's a presence of XFR.)
XFR and TB become effective at default. And it develops into Offset0.1250V problem ⇒ CPU is lack of the voltage and is a boot, and it isn't put on.
To refer to more biggest clocks of 1.40V or 1.50V for default, a fixation kill⇒ mother is dead (The voltage be reset for some reason, a bumpkin includes it, and.)

Is Ryzen's P state disabled forcibly? (Commentary)
● Verification: X370 Taichi

(Report from blog)
For the time being, "AMD Cooling function" & "C State function", so the voltage is in the state only below 1,55GHz
P2 State is AGESA prepared by AMD. Whether it is fully adapted depends on the manufacturer.

"Intel pressure"
The P2 State function can execute programs. However
Whether "Custom P State" is functioning properly depends on the manufacturer (⇒ It is implemented, but buggy.)
Offset 0.125V problem is also "Intel's pressure", XFR and TB boost were implemented, but there is a bug

<want to lower the voltage>
1: P State from 1.55GHz to 3.8GHz cannot be set. The CPU clock is forced to P0 when the power plan balance is exceeded.
2: In case of MSI-X370, you can use P2 State
3: Most motherboards can only turn "ON" in states below 1.55GHz or 2.2Ghz
4: Custom P State "AUTO" = "ON" (but not Enable) ⇒ It is correct to leave it in AUTO
5: CPU clock must be specified! ⇒ If you leave it in AUTO, the CPU will be forcibly booted at 4.0GHz to 4.3GHz and the PC will not boot.
6: For voltage, "Do not specify voltage for MSI" or "There is a risk that the mother will die only in MSI. On that assumption, specify the CPU clock and then input + voltage"

<Is the CPU clock actually going down? >
There is a strong possibility that the CPU clock has dropped internally to 2.2GHz.
If you want to use a voltage less than 1.55 Ghz, "only when you sign out of Windows 10" it becomes valid.
CPU clock dropped to 0.9GHz on MSI motherboard for that motherboard which cannot set voltage
It is a benchmark of 7Zip.
"Only for power saving plans" State function was used
(The score will be 2.2 Ghz.)
When the power plan is used more than the balance ⇒ PC becomes compulsory P0 State

(Q) I bought the 1600AF for some reason. Where is the voltage setting? ..
⇒ Spec guarantee "It is the same voltage as Ryzen 1700 of 14 nm"
First is 3.5Ghz-1.2375V (Offset "-0.10V").
⇒ Perform voltage survey on Windows 10! !
⇒ This is not ZEN +. MAX is about 4.0GHz, 4.1Ghz
With ZEN +, it is 1.10V (Offset 0.000V) at 3.8GHz.
The 1600AF has a higher voltage of 3.6GHz than ZEN +.
The voltage of the Ryzen 1600AF increases significantly from 3.7GHz.
When the CPU becomes 3.8ghz, "Vcore 1.30V Offset -0.10V" is a standard.
The voltage of 3.7GHz is done with Windows 10.
You use the MSI After burner and Ryzen Master. The model that cannot reset the voltage must not be done on the motherboard side.
4GHz-1.275V is NG ⇒ 1600AF fits that. ZEN1 requires 1.425V or more.
What about 4.1GHz? ⇒ That is a false report. Not in the first place. It requires a voltage higher than ZEN + at 3.8 GHz.
(When written in English, the tone, the wording when writing a lie, and the atmosphere are indistinguishable in a foreign language.)
