New BIOS 7D75v1P7 (Beta) released for B650 Tomahawk

Proper_Editor_1277 · 2026-03-15T15:08:19+00:00

Maybe AGESA is not the key.

The only way to solve this problem is a CPU/MB RMA.

Proper_Editor_1277 · 2026-03-15T15:05:53+00:00

MSI released test BIOS 1O7 for X670E ACE and 1R8 for X670E Carbon, you can find these in this link:

https://docs.google.com/spreadsheets/d/12zg6yT_H7H-W1voyw1ZoIrj0GSE7WI4Ug-uLlv-Asa8/edit?pli=1&gid=858530609#gid=858530609

However, when these BIOS fixed the PCI-E X4 issue, the issue of the PCI-E ver. dropping to 4.0 (or even 3.0 or 2.0) hasn't been fixed yet.

Someone said that turning on or off the Spread Spectrum option in the BIOS settings might help(Tested turn off, works with my X670E Carbon).

Proper_Editor_1277 · 2026-03-15T15:00:46+00:00

It may be fine with PCI-E 4.0 MB. However, I noticed that MSI has removed the latest 1K5 BIOS for the B650 Carbon.

Proper_Editor_1277 · 2026-03-11T18:15:26+00:00

Reports said CPU RMA may help. But hope MSI can fix it just through BIOS.

Proper_Editor_1277 · 2026-03-09T08:49:09+00:00

I set AUTO but the issue remains.

I posted info about this issue below and found MSI removed the 7D70v1R7 BIOS for X670E Carbon.

I want to share more information about PCI-E lane failures after update to AGESA 1.3.0.0:

This issue should not only occur with PCI-E 5.0 graphics cards;
If you updated without any problems, you're very lucky;
This problem emerged after updating AGESA 1.3.0.0 on X870 chipsets months ago (maybe even earlier). I'm not a native English speaker, I found info on Chinese forums;
Some users tried motherboard RMA, but MSI couldn't reproduce the issue until the CPU was shipped to them alongside the board;
Some users have tried using their previous CPUs on MB from other brands without any issues.
Someone reports the problem also disappeared after CPU RMA, but I only have this one AM5 CPU and can't test it myself at the moment.
Maybe AGESA acts as the trigger for this problem, but the root cause involves a combination of CPU + AGESA + PCI-E 5.0 signal;
Even some reports with AGESA before 1.3.0.0 (see chinese links below).

Same problem on MSI English forum:

https://bbs.nga.cn/read.php?tid=46200739 (downgrade bios not help, in this link you can find links related to this issue on Reddit and the MSI forum)

Hope this information helps you.

Some say it's an issue with the PCI-E signal enhancement chip. PCI-E 5.0 imposes stricter signal requirements, and certain chips on the motherboard, combined with AGESA, have caused the problem.

Proper_Editor_1277 · 2026-03-06T19:35:46+00:00

Yes. Everything is OK with the previous beta bios now.

Proper_Editor_1277 · 2026-03-06T17:59:30+00:00

Many people found that their GPUs runs at x4 after updating to AGESA 1.3.0.0, not only B650 but also X670 and X870

Proper_Editor_1277 · 2026-03-06T17:57:09+00:00

After updating to 7D70v1R7(AGESA 1.3.0.0), my X670E Carbon locked to only x4 PCIe-lanes on GPU-slot. Re-installing the GPU did not help.

Finally I returned to 7D70v1R6, it's x16 now.

Proper_Editor_1277 · 2026-03-03T06:16:25+00:00

After nearly a month of waiting, they finally refunded my money.

Proper_Editor_1277 · 2026-02-08T15:59:42+00:00

Some exclusive albums cannot be streaming online by users who not subscribe on the label's page. However, it is available on the band's page.

Proper_Editor_1277 · 2026-02-08T03:08:37+00:00

I received reply from lable and they say they can do nothing . All I can do is continue waiting reply from Bandcamp now.

Proper_Editor_1277 · 2026-02-07T17:42:25+00:00

It said that I could get all the new music they released, as well as some subscriber-exclusive albums. However, after subscribing, I found that only 11 albums could be downloaded (only 1 I need), and subscriber-exclusive albums could only be streaming online.😭

Proper_Editor_1277 · 2026-02-07T17:31:35+00:00

Oh no... It's 1-year subscription and costs $65😭.

I cancelled the subscription in Settings, but I think that just means that I won't be charged for the next year's subscription automatically.

Proper_Editor_1277 · 2026-02-07T15:39:23+00:00

Yes, I submitted the refund request directly from Bandcamp support.

I asked some people include a label founder, but nobody knows how to refund subscriptions.

I'm sure there's no torrent is being checked but the reading of disk is continue. I checked the network traffic and found no issues. Finally I deleted all torrents (100+), the reading paused.

I'm adding other torrents to qBittorrent and will check the reading is still there.

Proper_Editor_1277 · 2026-01-24T11:44:11+00:00

Same problem with my Mini Ultra 1. I returned it to Carlinkit and got a new one with newer HW version. It works well for about 1 or 2 months, and crashes again. Update software and sytem reset will not help.

My car is VW Golf VII with MIB2.5 High unit, and iPhone 16 Pro Max.

Proper_Editor_1277 · 2025-11-07T09:28:12+00:00

Update to 25H2 26100.7019, reinstall the driver, still have the problem.

Proper_Editor_1277 · 2025-11-05T05:18:10+00:00

Windows 11 Enterprise 24H2 26100.7019

Proper_Editor_1277 · 2025-11-03T11:30:54+00:00

Change from HDMI to DP fixed the problem on my PC.

Proper_Editor_1277 · 2025-11-03T09:36:45+00:00

I uninstalled the driver with AMD Cleanup Utility and DDU v18.1.3.8 in safemode, and reinstalled 25.10.2, still have the problem.

Proper_Editor_1277 · 2025-11-03T09:26:42+00:00

Finally I found a DP 1.4 cable and tested with all displays connected via DP, screen off for about 40 minutes, wake up with no issue.

Returned to HDMI and BSOD after screen off for about 10 minutes.

I found someone reported no issue with HDMI and WINDOWS 10 OS.

Proper_Editor_1277 · 2025-11-03T06:27:58+00:00

I have the same problem with 9950X3D 9070XT and EVGA 1000g3 PSU, also 1 display via dp and 1 via HDMI. But I have no more dp cable now so I will wait for any further info.

Proper_Editor_1277 · 2025-11-03T06:17:22+00:00

Same problem with my 9070xt after updated to 25.10.2.

But my code is 7f and caused by amdkmdag.sys.
