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!

Ahhh yes the Tomahawk issue has been resolved it seems. But the Godlike still has not been addressed and MSI keeps telling me I need to RMA my board.

The question is, which one of us is going to be the guinea pig to see if an RMA works? We have some Godlike users here claiming they do not have the problem, so what's the issue...a bad build date batch?

Yeah idk, mine was built in December 2024 and I've seen others with the same date having the same issue. It was not easy installing mine and the cable management took a lot of effort as well so I'm not quite at that point yet to rip it out and send it to them just for them to send it back to me and tell me they couldn't replicate the issue...

I'm going to see if I can get a hold of Gamers Nexus, I'm sure Steve would love to deep dive on this.

I have the godlike December 2024 mfr date with latest bios and Samsung 9100 in M2_1. I'm not able to replicate the speed issue - tried multiple sleeps, reboot, power off/on etc. Checking with Crystaldiskmark, always get ~14,000 MB/s Seq q8. Does anyone have advice for how to try to force the issue? I'll probably just move to M2_2 before I finish my build, don't want to have it crop up after I finish the GPU waterblock but hate to lose some USB...

I'm not for certain, but I think all of us that are having the issue have both M2_1 and M2_2 populated with drives.

Yeah it's just unacceptable for a $1400 MOBO. I was thinking class action lawsuit as well. I'm also gonna see how to contact Steve from Gamers Nexus. I'm honestly shocked none of the big YouTube channels have picked up on this yet.

Because some of them are just in it for the revenue from views and subs and don't give a [***CENSORED***]. Gamer Nexus maybe different but other content creators such as, "TheProvokedPrawn" deleted my detailed post explaining the M2_1 bug and then asking for him to test it on one of his PC NVME video uploads. A total [***CENSORED***] clown, if you ask me when your trying to help spread awareness to the community about this current situation.

Spreading it for the awareness aspect is extremely helpful. Windows still boots pretty fast at 900MB/s, so most people will have this issue and unless they benchmark their system after they build it have no idea their drives are running 16 times slower than it should until sometime past the return window. Also important so people know before anyone else buys a Godlike, or MSI's motherboards in general. MSI's response seems to be pretty rigidly "unable to reproduce, RMA" at this point, so its clear they are not even trying to fix it anymore.

Good information on the single nvme. It's easy to get lost in all the conversations here on who it effects.

An interesting thing, after reading one of the previous posts about how they had their bios setup (not having the issue), I poked around in it a bit myself and changed a few settings. Not to be exact with what he did though.
What I changed:
HD Audio Controller to Disabled
Integrated Graphics to Disabled
Legacy USB Support to Auto
Onboard Wi-Fi/BT to BT only

Since doing this I have had 100% Shutdown/Reboots (about 15) without the speed issue. I'm going to keep monitoring and not call a victory yet as it could just be coincidence. However, I have never had this many good restarts since having the board. Perhaps one of these could be a contributing factor.

Regarding on the Godlike X870E issue:

I’ve contacted MSI on both Live Chat and Support Ticket. I’ve forwarded this post and the Reddit post to both communication methods and the response I got maybe given me some slither of hope.

For Live Chat, I told them to forward both the Reddit thread and the forum thread to the engineering team, which they said they will (not sure if they actually will do that, but I’m an optimist).

For the Support Ticket, I did not get response of immediate RMA request. Instead, I got response of the usual (or unusual) workarounds which is rebooting my PC, disable Fast Boot (which isn’t even an option on the Godlike X870E unless I’m blind) and forcing the M.2 drive to Gen5 mode. But not before they mentioned “until a BIOS update is release“ and “until BIOS fix).

So, I guess they have acknowledged it?

Yeah I want to save the hassle of RMA'ing my board until I hear for certain newer boards don't have this issue. Not convinced they have fixed it

It's just a cookie cutter response. I got the same response for my issue--which they apparently didn't even read. My issue isn't that it's not connecting at 5.0x4 link speed--on my board (the X870-non-E), it /is/ connecting at 5.0x4. However the read speeds are still abysmally slow. Forcing it to 5.0 mode doesn't change anything--it's already doing that much.

Just curios what your speeds are?
