M.2 not showing after CPU upgrade

Nayrol
 Share

Hi there I have been doing a bit of internet sleuthing to see if anyone else has had the same issue as me and I can see there are some people however not to the same extent which is why I thought id make this post.
I Upgraded my CPU from a Ryzen 2700x to a 5600x on my existing Asus prime X470 Pro. Before doing so I made sure the bios was at the latest version (as of writing Version 5861 is the latest and I had to go all the way from 4011) install the CPU everything boots up and straight into bios not problems at all until it gets to setting boot options I can see both my HDD and SSD are there no problem at all however the M.2 is not showing, I swapped the CPU out to the old 2700x and it booted into windows straight away with no issues I can see there have already been some suggestions on threads which I have followed as well such as making sure to enable UEFI however so far nothing seems to have helped so I am at a total dead end and feeling pretty rotten about it so any help is appreciated.

You may didn't set up UEFI correctly. Try this one:

 - Open your bios

 - Boot

 - CSM (Compatibility Support Module)

 - be sure that Launch CSM is enabled

 - Boot Device Control should be set to UEFI and Legacy OPROM

 - Boot from Storage Devices should be set to UEFI only

 - Also, make sure that your boot order is correct

 

I hope you all the best ❤️

Thanks for reaching out I was fairly certain I had already done what you suggested but I though it better to try again any way just to make 100% sure I put in the 5600x again and followed your instructions and it still only shows two of my drives issue with this being the one drive that isn’t showing (the m.2) is the drive that has my OS on it so either way my boot order will be wrong. 
 

Thanks for responding though ❤️

Which M.2 slot did you put the SSD into?

IDEALLY, you want to use the top-most slot -- the slot underneath the "M.2 HEATSINK" cover.

 

The top slot runs the M.2 slot at PCI-E 3.0 X4 speed, with the lanes coming directly from the CPU.

The bottom slot is only up to PCI-E 3.0 X2, and it coming from the X470 motherboard chipset.

Plus, the second M.2 slot shares bandwidth with the SATA ports.

It’s installed in the top M.2 slot under the heat sink 🙂

Oh!

The Ryzen 5600X supports PCI-E 4.0, but your motherboard is only up to PCI-E 3.0.

There should be a setting in the BIOS to change your PCI-E lanes to run at [Auto] / [3.0] / ???

Try that if you haven't already.

Did you clear cmos? 

 

If yes or that didn't work, unplug the other drives and try booting. 

 

Maybe reinstall the cpu or ensure proper cooler installation.

I didn’t even think to check that actually! Just had a look now and all the settings are set to auto the only other option I had was PCIe raid mode so that’s a dead end as well I’m afraid

yeah I did a cmos clear that was my first assumption and looking at other threads that and removing all other dives was suggested as well so thought I better do that as well before posting.

 

cpu has been reinstalled same with cooler multiple times today just for my own sanity so that is all ok

If you are using 4 ram sticks, try 2.

 

Did you try a clean install onto the m.2?

Using 2 ram sticks.

can’t do a clean install onto the m.2 as it won’t show when I have the 5600x installed if a switch to the 2700x it’s there but with it being the drive that has the OS on it i second I do anything OS related it wont let me because it’s “in use”

Did you try an older bios?
