Maybe the issues are the same, but every board has a different BIOS, and it could be confusing looking for a BIOS version that doea not exist!

At worst, if you do manage to start a BIOS update that is not for your board you will probably brick your board.
Anyway, is 4.6 the latest version for your MB ? If so, is there a later BETA BIOS at the bottom of the list? If so, try that.
Do a CMOS clear  before updating, just good practice to do so.

You sure it is the same motherboard?   We are talking about the X70 Gaming ITX, and there is no BIOS version P4.60 for  that board

Thanks JohnM,  that behaviour plus the further issues that you outline  in your post in the BIOS thread mirror the problems I am having, exactly.
Although the problem is enough to prvent me from using that machine, it is a relief that I am not the unwitting cause of the problems.

PS: Have to add that these issues under BIOS 4.4 were not present with the CPU prior to the 2400G.
I was running an R3-1200 and it performed perfectly well, no issues at all, the finger is firmly pointed at the 2400G, or the 2400G and its performance under BIOS 4.4 that being the problem.

This is a known problem with UEFI BIOS P4.40. It affects some NVMe devices (eg. Samsung 960 EVO) but not others (eg. Toshiba OCZ RD400). They are not recognised in the M.2 socket. The problem has been reported to ASRock by a number of people and they have reproduced it. If you have an M.2 to PCIe x4 adapter card you can use your SSD in the motherboard PCIe slot as a temporary work-around. There is a beta BIOS on the web site but the links don't work. I think this will be resolved quite soon.]]> Tue, 20 Feb 2018 15:42:16 +0000 https://forum.asrock.com/forum_posts.asp?TID=7725&PID=45510&title=2400g-installed-now-lost-m-2-boot#45510 <![CDATA[2400G installed, now lost M.2 boot : That actually makes a huge difference....]]> https://forum.asrock.com/forum_posts.asp?TID=7725&PID=45479&title=2400g-installed-now-lost-m-2-boot#45479 Author: nanohead

That actually makes a huge difference.  It is actually mirroring the behavior I had when I swapped in the 2400G for the R5 1600 yesterday.  

A couple of questions.   Can you get into BIOS?  And if so, can you see the M.2 in the drive table?

There is something oddly quirky about the 4.40 BIOS.  I have an M.2 that works fine, but I have a SATA SSD as my second disk that is sometimes there and sometimes not in BIOS.  It always shows up in Windows, but not always in the drive table in BIOS, which is odd.

Drives have 2 distinct states. One is to the hardware (in BIOS/Firmware) and the other is in the OS.  It is entirely possible that the motherboard/firmware see it fine, but windows is puking on it because of a corrupt signature file because of all the change that image of windows has had (1200, B350, then 1200 X370, then new CPU with integrated GPU.    It might seem like you never get to Windows, but in reality, you're failing when UEFI turns over control to Windows, and the signature is corrupt.  Might be a stretch, but seen this happen loads of times when new hardware is introduced to an existing Windows installation.

MisterJ,  OK, thanks, I will do that.it will be tomorrow now.
Thanks for offering to have a look.

SoniC.
As a very last option yes, but I am always careful to just let the CPU drop in under its own steam, if it hesitates it is positioned wrongly......I would never use the slightest force etc. But as a very last option, it would be inspected, so yes, thanks.

@stree when everything else fails, try to carefully remove, check the AM4 socket under a magnifying glass and re-seat your CPU.

And I really mean when you are out of other options (posted by other friendly users here) and just before RMAing your board .
Memory problems and PCIe Problems can indicate some bent pins. Especially with SR4/TR4 socket, but also AM4 is prone to this.
