MPG X870E CARBON WIFI Beta BIOS

Sort by date Sort by votes
My Carbon and 9950X3D with 7E49v1A3 working flawless. Expo +PBO enabled, no nvme slowdowns (3x 4TB wd850), wifi disappeared once, but after disabling power management on WiFi card, working good. No problems with 5090 and pcie. In general not a single problem after a week of usage. Is there any reason to update bios to A33? I know golden rule, do not fix if it working, but always….. What I have read so far, no benefits but some new/ returning problems with boot etc… My carbon boot like charm, cold, hot, etc…

A33 includes an AGESA patch that remediates a microcode vulnerability that allows unsigned microcode hot patches. It's pretty important to get installed now that the update has been released as threat actors will start targeting it, but probably not a drop-everything emergency. Schedule a time to work the update and re-do your settings.
@vic123159d02e5 and others have observed some performance gains and stability in overclocking as well. But it is still a fairly fresh BIOS and those that were seeing regular PCIe lockups do appear to still be observing them. I had it happen once yesterday when I resumed out of sleep before my update from A25 with a weird windows issue (start menu/explorer locking up whenever opening any windows control panel) after updating my chipset drivers, but a second reboot seemed to clear it up. We'll see how it resumes from sleep today and how it performs the rest of the day in a bit.

Sadly... second day in a row I've resumed from sleep and had it stuck at PCIe 1.1. Had to restart. This time I switched back PCIE_1 speed to "Auto" in the BIOS to see if this helps. Not sure what caused my computer to start doing this in A25 and now A33 as it had been running on A25 mostly stable for quite some time (about every 5th or 6th day I'd have to restart to resolve a slowness or initialization issue) and had the occasional black-screen restart I attributed to the nVidia driver being a dumpster fire for a few months now.

After the update to A33 my PC freezes on the MSI logo bootscreen.
Seems to happen after the PC is off for a while, so cold boot.
I have to turn the PC off and on again, otherwise it will not start.

One of the previous Bios versions had that bootloop issue with the connected USB devices.
I am so happy that I have spent so much money on this mainboard. It was really worth it.

Today it will not load windows at all any more. Gets stuck on the msi boot logo. Even after the initial cold boot. Moving back to an older version.

I can't remember to ever have had such a horrendous experience with a Mainboard. I think this is the last time to buy an msi one....

Honestly, a few of us here share the same feeling.
I was almost enthusiastic about A33, in the first few days, I saw a real performance gain compared to all BIOS versions since A26–A27. But it didn’t last. I could initially push the CO curve up to -46; now it only works at -40 and performs about the same as all the other slow BIOS versions. When I say the board has a mind of its own, I mean it, voltage spikes through the roof, sometimes the CPU reaches 1.390V and stays there, not just during brief spikes. At this point, I’m starting to think that no matter how many new BIOS updates the devs release, the real issue is just bad hardware.
The only thing this board does well is maintain stability at high BCLK and deliver good memory performance.

I wouldn't classified it as "BAD" hardware necessarily I would classified it as "THE AMD THING" in general as I mentioned before INTEL is way more OC friendly and settings + OC procedures are way more logical and far more stable once you hit the sweet spot , it was also a reason why I stick to INTEL for 30+ years with occasionally AMD adventures like now for example , ofc this lately INTEL fckups specially with 13/14GEN are inexcusable .

For whatever it's worth, I haven't experienced any issues regarding PCI_E speed being stuck or acting weird on my end but I do have an 7900XTX, so I think it might be directly related to NVIDIA cards or drivers.

A28 is stable on my 9950X3D (CO per Core -20 to -38)
64GB 6000MT/s tuned sub-timings at 28-38-38-50
vSOC 1.125V
VDD 1.43V, VDDQ 1.33V, VDDIO 1.33V
GDM Off, Nitro 1/2/0
FCLK 2200MHz
and 7900XTX. Haven't tested out A33 so far and I'm in no rush to do so.

I have tried multiple things to get my pc to consistently cold boot (system fully powered off for a day) without locking up with no success. Setting pci-e from auto to gen 4 or 5, nvme from auto to gen 4, not undervolting at all, multiple BIOS versions etc.. couple things i have noticed that tells me its going to fail at cold boot.
  1. 1. When I push the power button, only the CPU fans start right away.. case fans dont spin up at all. It gets passed the bios screen where the circle spins showing windows is loading.. There is then an audible "click" (like a relay being tripped) and then the case fans come on. Its like the motherboard is not outputting correct voltage (or voltage at all) to 12v, 5, and 3v. When it does cold boot, that audible click happens almost instantly and both the CPU and case fans spin up right away.

  3. 2. When it fails to cold boot, the LED's on my keyboard and mouse will turn on at the bios screen, shut off for a moment, then come back on while the circle is spinning showing windows is loading. They will then shut off and shortly after the circle stops spinning and the system just locks up. I then have to push the reset button and 9 out of 10 times it will then boot fine. sometimes It will lock up again and 2nd reset will boot.
When my PC does boot, i never have the issue with PCI-e being locked at 1x or any system instability. "If" it boots, it just works...

Also, I have tried different power supplies (both a Corsair 1000w and Seasonic 1000w) and 2 different ram kits and its the same problem...

System:
9800X3D
MSI x870e Carbon
Kingston Fury 32gb kit
Nvidia 5070 ti (also tried a 3080 and same cold boot issue)
Corsair 1000w power supply
Samsung 990 Pro, 2 Samsung 990 Evo Plus

Wonder if people are experiencing this with other x870e boards from Asus, Gigabyte, Asrock, etc.. All i know is I cant recommend the MSI Carbon due to this issue

RMA, looks like faulty mobo.

Yeah, in the same boat. It's not just the motherboards from MSI that I'll avoid though. This lack of communication or overall support targeting known issues tells me that something's changed in MSI's structure. Maybe this is hardware, or lack of quality control on the hardware validation. For a top-tier mainboard there should be some immediate response and working with us to resolve issues.
I've had several opportunities to pick up a 5090 from MSI now and... nah, no thanks. I'll wait. Up until this board, I bought pretty much exclusively MSI.

Try to use typical current idle setting in overclocking /CBS section, also for cpu voltage try to set amd overclocking to auto. I may be wrong on this, but it does feel your cpu does not get enough juice.
Ps: also (without forcing) , look if your cpu is correctly sitting in your socket.

That’s my fourth msi board i think, the two I used with intel cpus were great. The one i had with a 5800x already gave me usb problems, but the mpg carbon x870e is by far the most expensive and the worst one !

„the neighbor's grass is greener” my first AMD was x570 Aorus Master, mobo was great for me, so I bought X670E Aorus Master. This mobo was absolute nightmare, so replaced this garbage with x670E Taichi Carrara. This mobo was great so I bought X870E Taichi for 9950X3D build. Returned it after reading about cpu drama. Bought MSI x870E Carbon, after reading on Reddit that Asus Croshair is POS mobo with tons of problems. There is no good solution this days. Shitshow everywhere. Fingers crossed, my Carbon is good so far. Btw. F..k A33 lottery good/bad for my build.

I checked the CPU, no bent pins and it's aligned correctly. Also reseated Ram.

Settings right now: (everything else is default)
AMD Overclocking:
Expo 6000 (CL30-36-36-80) with Kingston Furry 32gb kit Hynix A-die
PBO: Advanced
PBO Limits: Motherboard
Curve Optimizer: All core, negative, 20

CPU will idle at 42c in BIOS, in windows Hwinfo64 shows 39c.
CPU Core voltage showing 1.166 V in bios at idle
I do see 1 critical error in windows system log when it fails to boot "The system has rebooted without cleanly shutting down" so its like windows booted, but i never made it to the desktop. just freezes at bios screen with the spinning circle showing windows loading but circle also stops moving..

Cinebench r23 will run 30 min with no issues, memtest no issues, and Aida64 no issues..

Screenshot shows voltage with those settings idle in BIOS.

Just stumped here at this point.. Anything else I should check?

Did you try to set current type at typical current ? Also does that happens with no co curve at all ?
Does that happen with other bios version ?
If it's yes to all 3 questions, I do think you should RMA the board or the cpu.( most likely the board)

Guys, I also noticed that a strange temperature sensor showed up in HWiNFO — T15.
And in AIDA64 it’s listed as T Sensor.
I hadn’t noticed it before.
Could someone check if they have it too?

T15 is the 2 pins on the motherboard (T_SEN1 on the user manual) for an external temp probe. I use it for my water temp probe.
