Hello, just installed my new Asus X870E-E Strix motherboard, loving it so far. When I initially got in to Windows, all of my drives were present (even the new one that wasn't formatted yet was showing in Disk Management) - I updated everything in terms of latest drivers for the motherboard etc, rebooted and enabled EXPO on my RAM, set to 6000MHz with voltages set, didn't touch any other settings...
And now one of my M.2 drives is not showing up in BIOS or in Windows? I've tried changing the BIOS setting for Bifurcation to GPU+M.2 mode, that doesn't help. Any suggestions as to what else I can try? I have a feeling it's related to the whole thing of the GPU slot & the M.2-2 & M.2-3 sharing bandwidth, but the drive that's in one of them is showing up while the other is not now.
I'm going to try disabling EXPO & see if that helps for some reason... wouldn't make any sense if that was it, but perhaps the BIOS version I'm on is messing something up.

put your gpu and all you m.2 drives in gen 3 mode even if they are not gen 3 ....gen 4 fricken hates overclocking

I have the same issue on my x870e hero, shows up in bios but disappears from windows. I've been able to get it to show up by rescanning the storage controllers in device manager.

Well, if you look on the specs page of the Crosshair then you will find this footnote under 'Storage':
When M.2_3 are enabled, PCIEX16_1 will run x8, and PCIEX16_2 will run x4, M.2_2 will be disabled
I'm, like, 97% sure or so 😉 that the same footnote could originally be found on the page of the X870E-E as well (I own that board myself) but was removed for some reason.
Anyway, the footnote was always slightly unclear to me, maybe because English is not my first language and because of the way they put the commas, but the way I interpreted it (which is why I put the relevant parts in bold in the quote above) is that it is basically saying that if you put a drive in M2_3 that M2_2 will be disabled, i.e. you can only have a drive in either one slot but not both(?).
I could be wrong, of course, but that is how I understood the whole thing. I never gave it much attention because as a gamer I definitely do NOT want to occupy M2_2 and M2_3 anyway as both have the effect of at least halving the graphics card slot's bandwidth.
I have plugged three SSDs into my X870E-E and I'm using M2_1 for the system SSD (Samsung 990 Pro 4TB) and then I'm using M2_4 with another 4TB Samsung 990 Pro and M2_5 with a Kingston KC3000 4TB.
This config is running absolutely flawless. The Samsung 990 Pro in M2_1 does get a bit warm at currently 46°C but it is nothing to worry about. The other 990 Pro in M2_4 is 13°C cooler btw at only 33°C and the Kingston in M2_5 "wins" at 25°C.
Come to think of it, I shortly plugged my two old 2TB 990 Pros, which I eBayed in the meantime, into slots 2 and 3 to secure erase them and to take CrystalDiskInfo screenshots for the eBay auction and I seem to remember a similar issue as you guys described. I believe I also "lost" one drive during a reboot.
However, because of the quoted footnote above, I was actually surprised for a moment when both SSDs were discovered because I thought that the slots would be mutually exclusive anyway.
As I said, I seem to remember that the same footnote was also on the X870E-E page initially and not just on the Crosshair's page but I can not be 100% sure. If I read the footnote correctly then the bug might actually be that both drives get discovered instead of the other way around 😉 , i.e. one drive disappearing might actually be "normal"(?).

According to the manual, before I got the board, I did the research. The way it is supposed to work is if m2-2 and/or m2-3 are occupied, your PCIe x16 primary slot runs at x8. But both drives should work. It also explicitly states in bios that the setting for "gpu+m.2 storage" SHOULD enable both m.2 drives at the same time while seeing the gpu slot to x8, but as I said in my research, it actually does the opposite, it disables both m.2 slots for me. Haven't had anyone else test it & reply back if it has a similar effect for them. I think Asus is trying to downplay this as not a widespread issue when it clearly is at least somewhat.
I'll report back tomorrow with news on what settings cause what when I start messing with things again. But in my recent usage, all 5 m.2 drives are still working, and I don't really know why lol

I have this EXACT same issue after updating to the 0606 BIOS on my Strix X870E-E Gaming Wi-Fi. Secondary NVME Drive does not show in BIOS or windows. It did before the BIOS update. I manually adjusted my DRAM timings and set my speed to 6000. Strange. This is a bug for sure and hopefully ASUS will rectify in the next BIOS update? Thanks for posting this, I don't feel as confused now.

Which bios version was it working on? Because I know in my experience thus far, 0606 & 0223 (the bios most boards ship with) both have the problem.
I can say that I've yet to have the drive disappear again. I'll be messing with it more tomorrow to see if I can get it to happen again then I'll RMA it with Amazon, hopefully a new board will solve the problem. Not looking forward to swapping it out though, giant pain in the arse.

Also think it's worthy of note, that M.2 temperatures are dependent on several things: Heatsink size, proper contact via thermal pad with the heatsink, and how the drive is setup (if it's dual sided or single sided, etc) - the thing that runs the hottest on most M.2 SSDs is actually the controller, Samsung Pros have 3 drive temperatures, Drive Temp 3 is the controller (which should be the warmest one).
As an example, here's what my drives are at right now, C, Z & T are under the thicker heatsinks (C is M.2-1, Z & T are M.2-2 & M.2-3), D & E are under the other thinner heatsink down at the bottom in M.2-4 and M.2-5... and then Q is in the Sabrent M.2 PCIe x4 4.0 card I have, which has a dedicated heatsink, I also have thermal pads on both sides of it so it's spreading it's heat-load to the heatsink as well as the card's PCB... which is why it runs cool:
E & D are getting the "benefit" of GPU airflow whenever I'm gaming, Q has a fan that blows on it directly (underneath, that also blows air at the GPU), and C/T/Z all have airflow from the fan I have positioned towards them & my System RAM (to keep it cooler because 2x48GB can run quite warm without airflow especially when you're pushing timings/voltage etc).
But C (the one under the primary heatsink) idles a good 4-5C cooler than D&E, and under load it's a much bigger difference, I tested that in CrystalDisk a bit, and it's upwards of 5-10C under load.
I also thought MAYBE the thermal pad being a bit thick for a double sided M.2 (which the Z: drive, ADATA 4TB, is double sided) might be causing the issue, but it occurred with a single sided M.2 in the slot previously during my trouble shooting with the Asus Tech... so, while I probably should make that pad thinner so it's not so squished (you can literally read the ADATA that's on the chips of the M.2, in the thermal pad, when I take the heatsinks off), it's not causing a 'problem' at least.

I have a x870e Hero and one of my m.2 drives disappeared anytime I messed with memory after a reboot. Going into dram timing and setting memory contextual restore to enabled fixed it for me. If I didn't do that, I'd have to change memory settings every boot and do a fresh training of my memory. The bug is memory related for sure.

I think in my case MCR is enabled by default, but I'll have to check it out...
Funny thing is... I literally can't get the error to happen again now. I've messed with voltages, RAM speeds, timings, FCLK speed, hell I'm even testing a ECLK OC that's putting my 7800X3D up to 5.25GHz max boost with ~5GHz all core max boost under Cinebench R23 load, and it STILL hasn't happened again.
Maybe, juuuuust maybe, it did have something to do with mounting pressure on the CPU after all, or it's just a random bug that went away? Really concerned it's going to crop up after my Amazon return window has expired, but I messed with the BIOS pretty extensively yesterday & the drive is still there.

So I have the Strix x870e-e and am having the same issue where my Samsung 990 pro intermittently does not show up installed in the m.2_2 slot. All my other NVME and SATA drives have not had issues, and I have nothing installed in m.2_3. After some time what I am noticing is that any time I plug in my monitor;s USB hub to the motherboard, I lose the Samsung drive in m.2_2 in the bios and in windows. If I unplug it and restart, it immediately comes back up. Its funny and sad, because this is an ASUS PG32UCDM monitor. I'm wondering if it may be the USB extension cable, as it may not be USB 3 cable capable of 10G speed? Also of note, this issue was present before I turned PBO on. I have all the latest drivers/bios and the USB firmware on the Asus site. I saw someone online post that their MSI tomahawk X870 had the same issue with a USB hub, with no resolution. Has anyone else noticed this?
I really hope ASUS comes up with a solution to the issue, as I'd like to use the USB hub on my new $1400 monitor.
My other specs:
9800x3d PBO
G. Skill Neo5 64gb 6000mhz CL30 in Expo 1
Crucial T700 Gen5 SSD in M.2_1
RTX 4090FE
