So, the M.2_1 slot keeps reverting to PCIe 1 x 4 on a cold boot, sometimes just a reboot from within Windows. Manually setting it to Gen 4 or 5 within the BIOS will get it to run full speed until the next shut down/cold boot, then it's back to 1 x 4 again. Basically, I have to keep switching between gen 4 and 5 setting on every boot or it's stuck at 1 x 4. Auto is also broken. Samsung 990 Evo Plus 1TB.

I've seen another user on Reddit with the exact same issue. Same board, different drive. Anyone using this board, check your drive speed!
 
Yeah that's exactly what I'm terrified of, I'm hoping it either gets fixed, or they send me a new MOBO manufactured from this year (mine is from December 2024 batch).

I'm not done self troubleshooting yet, but nothing has worked yet so I'm not very optimistic 🤬
Mine has done this before too. I've got it to come back on by physically unplugging it while the system is on and then putting it back in. I think its happened to me 2-3 times since ownership.
 
I can confirm this is not just an issue with the tomahawk. looking at other threads it appears this might be a general issue with all or most of the x870e boards. I have gone through 2 x870e Godlikes and it seems to be an issue there as well not only for me but many other users that have been posting in the thread regarding the problems with the EZ Bridge on the godlike. as of yet there is no "fix" for this issue and many have replaced or done an RMA to only get a refurbished board with the exact same problems and some other user's wear and tear even when replacing a brand new board

These boards are a mess

Hmm I haven't tried unplugging it while it's on, but I pulled it off yesterday after everything was powered down and unplugged and just reconnected it today, still wouldn't turn on or anything...

So

[***CENSORED***]

Aggravating, for a goddamn $1400 MOBO.

I think it's time to start looking for a law firm that wants to start a class action lawsuit.

you are very welcome to try and get traction on that. but its not very likely to go anywhere. if it hasn't killed anyone or burned a house down there really isn't much they have to do other than say they are working to fix the issues and offer a refund or rma which they clearly offer. The problem is that there isn't really much in the way of any other board on the market that offers the number of slots and options but those are all "subjective" there are enough other solutions out there that you can easily get your refund and move to a different device. I say that as someone who is absolutely pissed off and will not buy into any further MSI products unless they change something and actually show a little transparency on providing fixes for these problems.

I don't suspect anything is going to change though. and outside of EVGA in the past, NONE of the other companies are any better. right now is just an absolute :poop: show for consumers especially those of us who wish to have high end systems.

Someone told me MSI does not offer refunds, only RMA and that if you want a refund you have to go through the merchant you purchased from..

I think it depends on where you purchase from, and also how long into the return window you are. in theory if you go through RMA with them multiple times and they can't fix the issue with the replacements, there is a good chance they fall under local consumer protection laws in your area and that would then determine the level of obligation they have to refund you. if they refuse to refund you and you can show they are providing a product that is not as advertised then its a good chance you have a case at that point. I just suspect its going to depend on the rep you get on your case and how far into the process you are and your area. I am by no means a legal expert but these are the things I have experienced and that may vary from what others experience so by no means take my rants and aggravation on this as full fact. All you can do is your best to work with who you purchased with and or msi at the end of the day and then any lawyer you might be able to get to look into your issue. you can easily provide at least 2 LONG threads of 2 separate issues for the lawyers to go through and find ALL of us that have the same issues. so there is no shortage of folk with the problems here that have posted and can attest to the issues.
 
So I just got another Godlike board (I think this is my 5th try...). All of the recent responses from MSI telling us an RMA is needed had me nearly convinced that MAYBE it actually is a hardware issue and since all of my other boards I tested were manufactured in October or December 2024, I thought a more recent one might work. This new one I got was manufactured in February 2025. It came with the December BIOS installed on it. I left the BIOS settings at default and after ~12 restarts m.2_1 worked as it should, but then the final time it started and reported m.2_1 was in PCIe4.0x4 yet benchmarked with 5.0x4 speeds. It was promising at first and that was more restarts than I normally get before it gets wonky and it still technically ran at the correct speeds according to the benchmark. So I then installed the latest BIOS 7E48v1A34, and set all my BIOS settings for normal use (EXPO enabled, changed m.2_2 to be x4 instead of x2, etc.) And.... it took 1 restart after that. And it immediately reported PCIe1.0x4 with a benchmark of around 900 MB/s. So nothing is different with the board from February. I got lucky with the first few startups and restarts, but now this is the exact same behavior as all of the others. I am glad I did not bother with the RMA on the one I already had, because it really seems like MSI is lying to us and the probability of an RMA fixing anything is near zero.

I am of the opinion a lawsuit will be worthwile. They are clearly not doing anything about it and this is very clearly false advertising. They are selling a product that does not do what they say it does. We can return it for a refund, but only if we bought it recently. Outside of the return window we are stuck with a non-functional board since its obvious an RMA wont solve anything. If nothing else, the initial legal notices sent to them might force their laywers to get the BIOS team to actually do something about it.

thanks for the feedback.

i'm glad i didn't RMA. my gut feeling told me the support rep didn't know what the problem was and assumed it must be a fluke and suggested RMA as a last resort out of ignorance.
wild that they went so far to say "godlike is different vs tomahawk and cannot be fixed via bios"

if you lawyer up, lemme know where I can join your class action :p

One of my correspondence with them said the same thing. They claimed to be a supervisor after I requested a phone call (which they did not do). I've also held on to mine thinking an RMA would not solve it.
 
Bumping this for us godlike sufferers when clearly a bios fix for Tomahawk works. At least MSI can explain why the bios fix for Tomahawk is not applicable to the Godlike according to them. (they wont, msi, really).

Yep seems to be random if it will happen or not
I dropped a full report the other day about the problem.
Out of 10 boot cycles, it has happened 3 times

This is the board I currently have. Manufacture Feb 2025.
now running on Bios A30

No problems with the DD3 doing disconnects so far.

I get your anger, but can you please skip the curse words.
 
Ok, we had a pretty severe storm on the night of the Memorial Day and we had a power outage and my PC went to sleep and after waking it up the next morning I felt it running slower than usual. I immediately went to check my M2_1 nvme PCI-E mode and speed and of course it went to 4x1 and 900MB/s speed. This is the first time I saw it on my board (X870E Godlike) since January of this year when I got my rig assembled. Rebooting the PC made it go back to normal.
 
up on this im using m2_1 , m2_2 and M2_4
i software raid the m2_2 and M2_4 the speed is only 3000 on cyrstaldiskmark it should be 3500x2 please fix this!
 
New build here same issues with current bios
7E59v2A6

on x870e tomahawk. This has NOT been fixed despite the claims here that the current bios solves it for tomahawk it does not!

System will still revert to pcie 1x4 on restart
 
Can't say I am surprised. Beta 2A41 was also supposed to be a solution but I continued to have issues while many others did not.

Currently I'm on BIOS 2A52 for a nearly a month and still no issues that I've seen, personally, but I don't think I will ever be 100% convinced that this is resolved. Eventually I will have to just bite the bullet and replace the board with something from another manufacturer.
 
After two months still no issues with the M2_1 port of my Tomahawk. Speed is constantly 4 x 4, benchmarks > 7000Mb. I used the 2A41 bios (1 month), the 2A52 bios (one week) then the 2A6 which I plan to stick with. In my case the fix works for now. Besides, I don't visit the forum often anymore, and I get the impression there are far fewer Tomahawk users here, which suggests most are no longer having problems. There are mostly Godlike users on this thread now.
