MSI MPG x870e Carbon WiFi Owners

and then I played with the BIOS again and wifi stopped working again in windows. had to reset cmos but at least I saved a bios profile. After resetting the BIOS back to default, wifi comes back again. I really don't want to play a process of illumination to work out which setting is the offender. this is dumb, a high end expensive board nerfed back to a normal board. I'm continuing asking MSI for a speedy resolution.
Edit: I spoke to MSI customer support and they couldn't advise when another BIOS would be released. They said they had never heard of this issue. I advised them many customers are having this issue and the advice I received from their engineer was to send the board back for a refund but they then explained it might happen on other boards using the same components and architecture. They said maybe go to intel, I cant obviously because I have a ryzen processor. I still have 2 weeks to send it back. Maybe another BIOS update will happen in the next couple of days, otherwise its going back.

Hmm, this is strange. Perhaps try the 1D BIOS linked in this post:

MSI MPG x870e Carbon WiFi Owners

Is there an issue with the 4090 and this board? In the BIOS i get some screen rendering issues with my ASUS TUF 4090 using display port to my screen, using the onboard via HDMI its fine. My 4090 has never had these issues with 2x Asus and 2x MSI Intel based boards though.

My disappearing wifi/bluetooth issues were solved with this BIOS. It also does not have the issue of the freezing in hardware monitor when editing tabular values directly. 1D has been the best BIOS so far. It was never published on the MSI website though.

I also found that it's important to install the wifi and bluetooth drivers that are linked on the MSI website rather than the ones that Windows update installs: https://www.msi.com/Motherboard/MPG-X870E-CARBON-WIFI/support#driver

I am running 1G at the moment and have not had any issues with the disappearing wifi/Bluetooth and blue screens when waking from sleep. I only had this on the 1A BIOS. I've just been editing my DC system fan curves in BIOS using drag/drop on the graphs for the moment, hoping MSI will fix the tabular entry of voltages though as it's much quicker. Anyway, I think I have the fans setup how I want them now.

It's good that you have the extra power connector hooked up too. So in summary, try BIOS 1D with the wifi and bluetooth drivers from the MSI website (check these are installed correctly by cross checking the version numbers in device manager), test for stability, then upgrade the BIOS to 1G and test again.

EDIT: If you are stable on 1D with the drivers from the MSI website, perhaps leave it there for the moment rather than moving back to 1G.

I haven't had a chance to buy any more fans yet, the stock installed ones on my corsair case aren't operating. but I intend to have all my fans PWM instead of voltage controlled so the voltage issue shouldn't affect me.
In the meantime Ive confirmed at least to myself that the wifi issue might just be a qualcomm driver issue in Zorin Linux that was not able to be updated preventing my wifi from working there.
Inadvertently I've now successfully got a dual linux/windows boot going and both load up successfully. I can get wifi in windows 11 but not in linux. Bluetooth is fine on both.
Now I'm not sure if it just happens to be working for me on the 1A1G bios released yesterday or if it has something to do with syncing my existing windows 10 account from my old computer and syncing all files and settings over to windows 11 on the new computer. I suppose I'll continue with windows 11 and periodically check for drivers for linux.

The driver should be available in kernel 6.11.x and maybe even backported to earlier 6.10.x/6.9.x depending on your distro, but you may also need a firmware blob?

What device family does it show up as with `lspci`? If it's "Network controller: Qualcomm Technologies, Inc WCN785x Wi-Fi 7(802.11be)", then I guess it _should_ be ath12k in case you do need a blob, not dual booting at the moment so can't really investigate further to try and help

Well after all that no sleep fog yesterday, while nodding off at the computer I accidentally clicked on a download folder and MSI emailed me directly just questioning my Qualcomm driver. I honestly thought I had already installed it twice because I remember downloading it twice directly from MSI's website. Maybe in my sleepiness I have confused that attempt with Linux, but it appeared I actually had a much older WIFI driver installed. feel so stupid now.
I've updated that driver now and can confirm that WIFI does now work with X3D Gaming mode turned on.
Thank you for your help in the issue. After also speaking to them on the phone they also confirmed in an email that they were able to reproduce the BIOS freezing on fan voltage attempts in the 1A1G BIOS release. I did try the 1D release, then went back to 1G to test again. MSI then confirmed they are looking at fixing that fan voltage freezing issue and will fix it on the next BIOS release soon. There was a hint that it might be related to the 1D release (but obviously going beyond the 1G).
I still need to plan for and buy more RGB fans which will be PWM fans so the voltage issue for the moment doesn't much affect me as I'm going for a white case, black components, clinical build with red blood components theme.
I tried again in Linux but nope. Yes I'll look into a firmware blob. That's not something I thought of. Thank you.
I wasn't expecting MSI to really help me much after the initial purchase of the motherboard. But MSI's direct & quick responses and being able to quickly talk to someone on the phone without going through too many phone options or departments has reaffirmed my faith in MSI as a reputable company to deal with.
 
Just to take it a bit further, I can yes see via lspci that the qualcomm device 1107 (rev 01) that was physically delivered on the actual piece of hardware was yes ath12k. My little understanding of the Qualcomm release notes for linux found in Qualcomm Linux documentation written in October shows that they're only up to ath11K+ but also suggests they are on rev 1.1, or 1.2. not sure if the rev number is important though.
That means to me that the ath12k hasn't found its way to the linux dev team at Qualcomm yet. Don't even know if I'm interpreting that correctly. then I got stuck in the mud in kernal release info and development kits related to the Qualcomm Fastconnect 7800 which does show support for 802.11#... Zorin linux kernal is based on 6.8 but qualcomms linux development is at 6.6.38. not sure if that means anything.
Maybe I should just wait for ath12k to find its way there. I'm not sure, its getting a bit Japanese to me now.

New Bios!

AMI BIOS7E49v1A21

Description:
- Fix HW Monitor abnormal behaviour.

Fantastic. This is exactly what I had opened a ticket with MSI support for last week! They actually emailed me a couple of days ago with a direct link to download it, I had not got round to trying it yet though. Hopefully voltages can now be entered in the tabular fields in HW monitor again without causing a freeze. I've been very impressed with MSI support and their quick responses to communication on the ticket.

That's not a bad response / turn around time, encouraging!
 
Flashed 1A1G a couple of days ago - testing mid-density ram kit (64G), quite anecdotal for now due to limited time
  • 6400/CL30 boots with lower voltages than previous BIOS but is not stable with tests
    • I have limited appetite to test dual/quad sticks above 55c, memory value consistency errors sneak in here hours later, had a few errors at +30 mins
  • With tREFI being maxed and the temps increases after that, there seems limited upside unless I can find decent direct ram cooling options

  • "Latency Killer" feature does indeed seem to reduce latency in artificial Aida64 tests, but consistenly reduces CPU benc scores by a small amount in e.g. CB23
    • Myt previous assumption was this changed tREFI to a higher value, that doesn't seem to be the case.

You can use 3 of the 4 slots in the following configuration: https://forums.overclockers.co.uk/threads/msi-mpg-x870e-carbon-wifi-owners.18994720/post-37471888

If you use the M2_2 slot, it will reduce the main PCIE slot to 8x

Thanks, helpful, its been unclear in the past to me when picking out boards (last time x570 mobos), in descriptions it sometimes sounds like using any more than 1 M2 will result in reduced PCI speed. I take it only the 2nd CPU M2 slot has this effect then and chipset M2 slots never affect main PCIe slot right?

Thanks

Correct. PCI_E1, PCI_E2 and M2_2 share the same bandwidth so as long as you leave M2_2 and PCI_E2 empty you're good to go.
 
Oh ********, I guessed if there was any sharing, it would be M2, 3 or 4, so used 1 and 2, will plan to move 2 to 3, it's a Steam game drive so shouldn't be an issue.

Ok, the scottish word for dangly things between your legs get's censored :)

Brothers and sisters. I bid you good morning.

My first post and I’m sorry to say I need your help and experience.

I have the x870e carbon motherboard. I have complete new build except for my gpu. Im running:

Msi gtx1070 gaming z. Pcie 1

Samsung 990 pro in m2.1
Wd 860 in slot 4. Previously in slot 3.

when running cpu-z it states my Pcie slot is running at 8x….

No matter what I do I cannot get it to change to 16x.

I think I have the bios configured wrong in some way even though I have pretty much left it at default.

I’m 3 days into my build and I’m already wondering if I’m gonna have to send back to Amazon.

I know the gpu is old but It had served me well and still does for now. Someone else suggested the mem bandwidth is too low and the main board is not registering it above 8x but that doesn’t feel right does it?

I will be changing the gpu at some point but not yet is the intention. And with this still in the air I am reluctant to spend hundreds of great British pounds until I know for sure.

Nothing looks or feels wrong. I just think I’m an idiot who has ent built in nearly a decade and I am hoping I just don’t know something‍♂️.

Please help guys
 
How is everyone finding the "Latency Killer" feature on this board? I'd been getting weird stutters and very low 0.1% lows in games with a 9800x3d and after trying all the typically recommended fixes like removing GPU power monitoring from afterburner then disabling EXPO and setting curve optimiser back to defaults it was still happening.

I tracked it down to the Latency Killer which when left on either enabled or auto gives me a higher latency score in Aida64 than disabling the feature, and disabling it also cured the issue with frametimes and poor 0.1% low performance. I'm now back with a negative curve optimiser and have EXPO enabled and tighter timings and everything's running beautifully.

Just wondering if anyone else has run across this where Latency Killer being auto enabled by default has been causing more harm than good or if it's just a weird peculiarity with my RAM kit. I'm running a 64GB 6000 C30 kit (CMT64GX5M2B6000Z30) which isn't on the QVL but apart from the Latency Killer thing it seems to run perfectly with EXPO and tighter timings. Weirdly I also get better latency performance in benchmarks without the feature enabled too around 70ns instead of 84.
 
Something I have found annoying with this mother board, if I put the computer to sleep and come back to it later on. It won't be long before it crashed and restarts, no blue screen or anything. Anybody else had this, maybe a fix in a new bios perhaps ?
