From reading the Asus forums, it sounds like 1.2.0.3d has issues. Prob why they already have 1.2.0.3e in beta. I just really want MSI to fix the pcie slot booting below gen 5... It works fine with spread spectrum on for me, but I shouldn't have to enable it just for that.

I don't have much hope for fixing the PCIe bug. It seems MSI isn't even trying to investigate it.
I contacted MSI support with 2 tickets about the issue in May and a few days ago, but got answers like "We kinda dunno lol, try changing the CPU or something."

New AGESA 1.2.0.3e bios out for X870e Tomahawk too

IMPORTANT heads up - DO NOT FLASH this new bios if you overclock Memory, or care about getting back to an older bios easily:
-Had a stable daily 7800 36-45 profile at 1.43V that would not even run with this bios at 38-48 at way looser timings AND way higher voltages, all with GearDown disabled only at Nitro 1-3-1. No, I’m not interested in enabling GearDown mode, or relaxing Nitro to 2-3-1. It has never been required at 7800 on this board with my CPU sample and 3 different 2x24GB kits
-Boots way too quickly than before, I suspect it's not training long enough, and couldn't extend the training duration despite playing with Robust training, Increasing RX and TX taps, setting Nitro to 8x/8x, etc. Tried every trick in the book
-Max stable on my setup was only 7600 MHz, which is ridiculous
-CPU PBO with curve optimiser was fine in general, found no difference in CPU perf

Tried to flash back the older A52 bios I was on, and it wouldn't even enter M-Flash, kept hanging at 0d, which has never happened before. Did the same after clear CMOS followed by M-flash, clear CMOS followed by restore defaults-> save/exit-> followed by M-flash. Once entering M-flash failed, it wouldn't even post anymore, hanging at Ab, 0d, 97 etc randomly.

This is just nonsense, what kind of QA/testing do they even do before releasing a bios? Having been with MSI for a while, I know if there is an additional digit after the primary bios # (the 3 after the 7 in this case), it is a Beta bios and needs to be taken with a pinch of salt, but not having tested the ability to let users get back to an older bios is inexcusable.

Had to resort to Bios flashback to get back to A6 which seems the same as A52 and perfectly stable so far.

While I personally can understand your frustration, having experienced similar issues with two AM4 ACE boards that drove me to switch to Intel, I believe the so-called "PCI bug" is not as widespread as it seems. It might be more related to certain components on the board, such as clock generators or controlling circuits. However, the technical explanation provided is rather vague. Suggesting changing the CPU or PSU without proper diagnostics is unacceptable. This is absurd. What I would recommend is purchasing a motherboard from a different vendor. If the issue does not persist, request a refund or consult a lawyer to open a case. This kind of unacceptable after-sales behavior is not exclusive to MSI; ASUS initiated these practices, and due to a lack of significant legal consequences or fines, other vendors have followed suit with similarly appalling and customer-unfriendly behavior.

It might be the frequency clock generator causing more spikes than when it was brand new, possibly due to "overly" overclocking the system and pushing it hard, leading to some degradation. Now you might need to use Spread Spectrum to keep the spikes under control, or it could simply be component degradation due to lower quality.
However, what you state, I don’t see anything for MSI to fix, and I’m not very MSI "protective." On the contrary, I’m very critical and bashing. I have no sympathy for BS, but in your case, it actually seems to be just fine.
Enjoy your system and who the F cares if Spread Spectrum is ON or OFF. If it works without it fine if it has to be enabled due to stability reasons fine again that's exactly the purpose of it.

Though, again, I'm not significantly overclocking my hardware as I prefer stability (base PBO and RAM adjustment since XMP is such a crapshoot). And any motherboard that starts "degrading" after 6 months of use has problems.
Additionally, the PCI issue persisted when installing a new processor until I enabled spread spectrum, on A41. I think some combination of the mainboards and CPU just aren't great. Spread Spectrum is supposed to reduce EMI, not keep your motherboard from allowing the PCIe speed to go to above v2. There's still SOME problem that other board manufacturers seem to have fixed, though I suppose we should count ourselves lucky that we didn't buy AsRocks.

Once again, I have the same combination of Carbon Wi-Fi and 9800X3D (purchased directly from AMD), and I have experienced zero issues never encountering any PCIe-related bugs, degradation to a lower generation, or being stuck. My Spectrum is OFF. I bought the motherboard and CPU about four months ago, and while I am not overclocking, I am using PBO tuning with the usual settings. The CPU reaches a maximum of 5420. My Corsair 48GB 7200 is running at 6400 CL32 +2200 Fabric+5090 Liquid SOC, and I have absolutely no issues, no stuttering in any game or any unusual behavior.
This shows how difficult it can be even for MSI to troubleshoot such cases. However, in my opinion, the appropriate course of action would be for MSI to request the motherboard back for inspection or, to enhance customer satisfaction, simply exchange it.
Just to add my PSU is ThermalTake Toughpower GF3 1200W Gold - TT Premium Edition which btw is not the over the top like some Sensonics or Corsairs and it drives the system without a glitch. And I saw a power draw of 605W easily in Cyberpunk by the 5090 alone.

After flashing the new BIOS version 7E49v1A42, I encountered an issue after a couple of restarts. I didn’t apply any overclocking—only enabled the XMP profile. The system got stuck at boot with code AB displayed on the motherboard. Resetting the BIOS is required to get it to boot again. However, the same issue reoccurs after enabled the XMP profile, Rolled back to the old BIOS—no issues.

It's possible that the new AGESA causes your RAM's XMP overclock to be unstable, and then be unable to get a good training. Saw some other comments about being unable to train the RAM and stability failures after an extremely short training cycle. Wonder if there's some new optimization to do.

I guess my next step is to buy a new board (another Carbon) from a newer batch and hope it will behave as it should. I've already tried a new kit of RAM (16x2@8000Mt/s by Teamgroup) with no luck. If the new mobo trick won't work, I think I'm gonna try new cpu, then a new psu and finally a new gpu (hopefully I won't have to).
PS: This is my first (and probably the last) AMD and MSI user experience lol)

Getting a 9950x3d and installing it reduced a significant amount of issues, I suspect the early batches of 9800x3ds had a problematic IMC. This didn't repair some of the board-based issues, like dropping USB and other earlier issues. Those were either fixed by BIOS updates or better drivers, or haven't yet been addressed like some PCIev5 slots not reliably resuming speed back from v2.0 without Spread Spectrum enabled.
If I have to get a new motherboard to fix an issue, it won't be from MSI.

Well, after a few hours using this A42 with my overclock profile I can only say: so far so good.
No crashes, stuttering, temp seems better. So, I'm happy
