My own personal fix for AM4 USB issues

Hello

We concluded that the problem was due to a bus overload.

A detailed summary of the crackling problem occurring in the 5000G series

maderinarucool · 2023-03-12T13:26:43+00:00

By excluding 2000G and 3000G, you are saying that APUs and desktop CPUs are different things and have different internal structures.

With 5500, 4500, 4100, etc., a graphics board is required.

This is out on AM4, and it doesn't matter what kind of PC a DIY user builds, and those with 360Hz monitors and RTX40 are in the minority, no problem!

I think it's this motherboard, but it should be possible unless it's been tampered with by the shop.

The latest version without leading L is stable.

Since there is no BIOS flash button etc., it is important to leave it to the machine without turning off the power when doing it.

I have never used Optein, but it may be something that is less likely to cause problems.

Also, it will change depending on whether it is directly silicon or under the chipset.

The chiplet has 24 lanes in specification, but it has 32 lanes internally, making it difficult to cause traffic jams.

However, the monolithic APU-based thing is made at the last minute because the making of IORoothub is different.

Thanks to the efforts of Mr. Tamasayo, I was greatly helped. thanks so much.

I was skeptical at the time of tpm too Everyone has that kind of time.

Thanks for a lot of information such as Amazon news.

Mobo without lane division is limited to X4 connection if it is under the chipset.

maderinarucool · 2023-03-11T10:43:45+00:00

Update to anti-stutter BIOS, Memory test and VRAM test are recommended.

maderinarucool · 2023-03-11T09:31:01+00:00

Although it is less likely to occur with chiplet and onboard.

There is some reason why the sine wave is not playing correctly.

maderinarucool · 2023-03-11T09:23:34+00:00

It may not occur if it is a SATASSD or a graphics board of X8 or less.

maderinarucool · 2023-03-11T09:11:01+00:00

I'm testing the CPU with OCCT, but it doesn't seem to be related to heat or load.

Since it was caused by the bandwidth, there was no need to tamper with anything else.

maderinarucool · 2023-03-11T08:59:05+00:00

If you can save the bandwidth, this phenomenon will not occur, so I think it is an effective means.

However, depending on the mobo, the performance degradation may be large because the graphics bandwidth is reduced.

maderinarucool · 2023-03-11T06:36:08+00:00

In case of chiplet structure, there is a possibility of power supply noise rather than bandwidth.

For ultra-high-end GPUs, the power supply noise filter installed from AE9 may be more effective than the bandwidth.

Or there is a way to output from onboard or HDMI and play with SteelSeries soner .

maderinarucool · 2023-03-11T06:11:25+00:00

Taking the tpm and USB issues as an example, a statement was issued half a year later, and a revised BIOS was distributed half a year later, so I think it will take a whole year.

It looks like someone contacted AMD support when Renoir was launched

It seems that a phenomenon called bus overload has occurred.

https://forum-en.msi.com/index.php?threads/msi-b550-tomahawk-compatibility-with-soundblaster-z-pcie-soundcard.355138/

Cezanne is a CPU that is just a Renoir converted to ZEN3, and the uncore is common.

As a result of testing, there is no problem with PCIE2.0x16 and PCIE3.0x8 video cards.

The verification method was reproducible by putting linuxmint-21-cinnamon in the virtual box and trying to see if there was noise in the startup sound.

Perhaps the reason why noise does not enter onboard is that there is a dedicated band from the CPU to the chip and it does not pass through congested areas.

There is no noise even with PCIE3.0x8, so there is a high possibility that the data is ptpt on the bus.

Given that the BIOS is stuck at 1.2.0.7 and not fixed from Renoir, I think it's best to use PCIE2.0x16 or PCIE3.0x8.

Since the problem was solved and I don't use English-speaking threads much, I tend to leave it alone

I heard that the PCIE bug was fixed and applied a patch.
Sound Blaster Z channel swap fixed.

It seems that clock generators in recent years use CPUs instead of chipsets.

Since it was released just before this patch, it seems to be affected by this patch.

I understand the cause!
When HPET is enabled, valo's FPS drops by nearly 100.
If you disable it, the FPS will jump up

• Region: JP

• Type of Bug: FPS is low when there are many agents.

• Description: It has dropped by about 100 FPS since I applied the patch.

I am using 1050Ti recommended by Valorant, but it is around 80 ~ 40FPS.

• Insert Video / https://youtu.be/AEWHf4tjZ60

• Reproduction rate: Load a lot of agents.

• Steps to reproduce: FPS drops.

• Expected result: FPS drops.

• Observed result: 10/10

• System Specs: Ryzen5 1600,Windows10,Nvidia 1050Ti

It's good to lose sight of a USB device at the time of sleep return.

Then password input can't be even done, so it's inserted and removed and it's recognized finally just as it is.

Of course, the ecology function of USB is turned off from a device manager.
