I recently bought the X870 Tomahawk to use with a 9800x3d and Corsair 2x16Gb 6000CL30 EXPO (CMK32GX5M2B6000Z30) but I'm having lots of issues...
Frequent crashes (windows sometimes shows "Clock watchdog timeout" BSOD, sometimes no blue screen), my NVME drives sometimes disappear (I need to turn off the power completely, a reboot isn't enough to show it again) making the OS unable to boot and I could not get the Wifi to work.

Today during a reboot there was a warning that the hardware changed so I press F1 to open the bios and the EXPO profile simply disappeared! I exit the bios, boot the system and now it only shows 4Gb of RAM?!? The system is very slow too.
I'm using the latest bios, but it isn't stable, please advise.

- AGESA ComboAM5 1.2.0.2b released. --> A16 AGESA ComboAM5 1.2.0.2a
- X3D Gaming Mode supported for Ryzen 9000X3D series CPU.

I have just finished updating and setting the settings. You have to change a few things because of the strangely selected default settings. At least as I know it from the past. There don't seem to be any problems with A17 for the time being, but the HD Audio Controller is showing up in the Device Manager again, although it is deactivated. The EZ Digit Debug LED shows the preset CPU temperature.

Even the fan settings are garbage. I had overlooked or forgotten them at the beginning. That's why my temperatures were far too high.

FYI:
The issue that onboard audio cannot be disabled, even HD Audio Controller is disabled in BIOS is duplicated,
and MSI people are working on solution.

I had already reported this problem to MSI. I hope that they are working on it. Also on the other two reported problems. They can also work on the boot time right away. If you measure it, you end up with just over a minute to the login screen! On my Asus board, if I remember, it was under 10 seconds to the login screen. ;) And with a 2s delay, so that you can comfortably press the Del key to enter the UEFI. MSI doesn't even have this option. :oops: My SN850X doesn't do anything for me at system startup on the MSI board. Zero. Nada.

So I had a code 10 issue when I had two sticks of ram installed. It wasn't even getting to the point of Code 15 where it does the memory check. This was at stock timings, stock settings, absolutely NOTHING plugged in but two sticks of ram, an m.2 ssd and a keyboard. Worked fine with just either stick. Also worked fine with another set of ram.

I was finding that sometimes when I booted into windows (90% of the time it wouldn't post... but sometimes it made it. Always took physical changes prompting the bios to re-learn what was installed) then sometimes my ddr5 modules were recognized as 4gb UNKNOWN modules just like yours in aida/hwinfo.

Some other ram seemed to work fine. I swapped out the ram at microcenter and nothing changed. After that I swapped out the motherboard and instantly the problem was gone. it's been fairly stable once the system is running but I just had a code 43 on reboot because ??? which never allowed the thing to post. "Memory is controlled by the CPU" is true, but the connections all travel through the motherboard - it's not like you plug the ram into the cpu. The bios and by extension the motherboard is responsible for a lot of interactions with the ram.

If you're still having problems with ram not being recognized and you're still within a return window for the board then i'd try swapping it out... or another motherboard model completely. I've never ever had this much trouble with a mobo. In my eyes this one is just not ready yet and it feels like we're alpha testing a motherboard. A cheapo $<100 board would be fine to limp along for 12 months until another reliable alternative comes out way under the $300 or $500 price points. It's not like this is going to be faster from a compute or gpu standpoint than the cheapest A620 board you can find even with a 9800x3d + 4090. You might lose some m.2 ssd throughput if you have a nvme5x4 drive, but 4k read/writes shouldn't be affected at all.

For me if I have one more issue that is from this board I think i'm done. With the people having socket issues with just this board so far as well it just doesn't look good.

I need the PC for work, I would have returned it already if it wasn't such a hassle, plus I don't have a lot of options (affordable) where I live... but I'm pretty much done with it too. If there's no fix in the next few days I'm gonna say goodbye to MSI for good. They don't even acknowledge that there are memory issues, even with several topics here in the forums...
Ironically, one of the reasons I bought the board was the numerical led error codes... Never thought I'd be watching them everyday :poop:

Seems like everyone gets answers here but me 😭 today Linux crashed because the nvme disappeared again, I reboot and only the other drives show up in bios. Only comes back after a full shutdown. Gonna buy an Asrock and never look back.

Leon, my problems are beginning to converge with yours. It began with the normal corsair EXPO incompatibility that everyone is experiencing, but now I'm starting to see memory errors with my new Team Group ram. First hint was when my freshly downloaded nvidia drivers wouldn't unpack and gave me a 7zip crc error. If you search for that, it points to a ram overclocking issue. Turning off EXPO fixed the error. I turned EXPO back on and ran TestMem5 with anta777's absolut config and sure enough I got a bunch of memory errors. So that's two sets of RAM that can't run on EXPO, and I specifically selected the team group set because it's advertised as compatible @ 6000 on the tomahawk support page.

What's wild is the slim chance to catch that memory error while unpacking GPU drivers. I suspect there are many tomahawk buyers sitting on unstable memory that just don't know it yet. I fully support your decision to swap brands. These guys are asleep at the wheel.

I once had an issue with an Asrock (taichi AM4), in 24h they made me a beta bios that fixed it. Now I'm either being ignored or just told to RMA (I cannot be without the PC for weeks, it's either a new board from different brand or fix this one).
I'm quite convinced as well that there's more people with similar issues. The problems are just so random it's hard to connect the dots. With the G.Skill memory it worked fine for a couple of days, until I did a reboot (full shutdown and sleep seem fine, reboots almost always mess up with memory error). Testmem5 was fine sometimes, not fine other times... There's obviously something wrong but without official help I can't find it.

Hi all,

I have a 9800x3D and the x870 Tomahawk and it wont boot with EXPO enabled. The thing is it wont even boot if i manually set it to anything higher than 4800 defaults.
The memory kit is:
Corsair Vengance CMK32GX5M2B6000Z30

(2x16GB) DDR5 6000MHz CL30 AMD EXPO​


Already contacted with MSI support and the response was:

Code: 
Regarding your concern, sorry to say we haven't tested the RAM CMK32GX5M2B6000Z30 on this motherboard.
Please clear CMOs referring to the manual, enter BIOS, press F6 to load optimized defaults, set EXPO to enabled, press F10 to save and reset to test again.
If the issue remains, please add a little DRAM voltage to test.
We also suggest you choose compatible RAM referring to the memory support list below. Thank you.

Could there be any issue with the board? or just very bad bios support right now?

Yeah you're not alone. It looks like everyone with that ram (both 32GB and 64GB versions) can't get EXPO to work. Based on the consistent pattern it feels like a bios issue. Either that or we've all stumbled on a bad batch that needs to be recalled.

I'm running silicon powers ddr5 64gb 6000 cl 30 that's on the MSI compatible list and they seem to be running fine. Just been experiencing other issues like the ethernet not working when plugged into my routers 10gig port and well all my data drives showing up as removable in windows...

I'm returning the MSI. Bought an Asrock x870 pro rs and everything seems fine right away... and it's cheaper too!
It's ridiculous that they claim this ram is not tested, IT IS on their compatibility list (for ryzen 7000 though). Now they will tell me the ryzen 9000 (with alleged increased memory speeds/compatibility) will not work at EXPO 6000? And the ryzen 7000 will?!?!?
Not to mention I changed the ram to a G.Skill kit (also on the list) and still had issues. The board is already back in the box, returning on monday.

Goodbye MSI.

Not likely as the 9000 has the same Internal Memory controller as the 700 series.
