Well, SATA ports work fine for HDDs, and those are still fine if you need bulk TB storage.]]> Wed, 13 May 2020 05:39:39 +0000 https://forum.asrock.com/forum_posts.asp?TID=14356&PID=75400&title=m2-nvme-not-recognized-on-most-cold-boots#75400 https://forum.asrock.com/forum_posts.asp?TID=14356&PID=75395&title=m2-nvme-not-recognized-on-most-cold-boots#75395 Author: DonYenko

Thinking exactly the same. Also, why are SATA3-only M2 ports not a thing of a past too. ]]> Wed, 13 May 2020 01:17:33 +0000 https://forum.asrock.com/forum_posts.asp?TID=14356&PID=75395&title=m2-nvme-not-recognized-on-most-cold-boots#75395 https://forum.asrock.com/forum_posts.asp?TID=14356&PID=75382&title=m2-nvme-not-recognized-on-most-cold-boots#75382 Author: Synapse

Oh sorry, I thought SATA-only M.2 are a thing of the past.]]> Tue, 12 May 2020 21:27:20 +0000 https://forum.asrock.com/forum_posts.asp?TID=14356&PID=75382&title=m2-nvme-not-recognized-on-most-cold-boots#75382 https://forum.asrock.com/forum_posts.asp?TID=14356&PID=75378&title=m2-nvme-not-recognized-on-most-cold-boots#75378 Author: DonYenko

Why would I put a NVMe drive, into lower M2 slot which is intended for SATA3-only M2 drives?

If that would work for some reason, that is a 4 times drop in achievable speeds!]]> Tue, 12 May 2020 20:06:32 +0000 https://forum.asrock.com/forum_posts.asp?TID=14356&PID=75378&title=m2-nvme-not-recognized-on-most-cold-boots#75378 https://forum.asrock.com/forum_posts.asp?TID=14356&PID=75371&title=m2-nvme-not-recognized-on-most-cold-boots#75371 Author: Synapse

Try installing it into the lower M.2 slot. This way it'll be connected through the chipset's PCIe, maybe that'll make a difference.]]> Tue, 12 May 2020 18:55:30 +0000 https://forum.asrock.com/forum_posts.asp?TID=14356&PID=75371&title=m2-nvme-not-recognized-on-most-cold-boots#75371 https://forum.asrock.com/forum_posts.asp?TID=14356&PID=75363&title=m2-nvme-not-recognized-on-most-cold-boots#75363 Author: DonYenko

Hi all,

since I purchased the M2 NVMe SSD last year, I am having issues with cold booting and sometimes even rebooting the system. Have in mind that this is not a Windows booting issue, this is "MBO refuses to recognize NVMe unless CMOS is cleared and settings reloaded"!

Here are the (important) specs:

• ASRock AB350 Pro4 (BIOS 6.30)


• AMD Ryzen 3600 (Cryorig H7 with uprated fan)


• Sapphire Nitro+ RX590 SE


• 2x Patriot Viper RGB 3000MHz 8GB PVR416G300C5KW (Micron H-die)


• ADATA ASX8200NP-240GT-C M2 NVMe SSD (installed in Ultra M2 slot)


• Seagate Barracuda Guardian 2TB 7200RPM ST2000DM008-2FR102


• Fortron Raider II 750W 80S

Behavior is as follows: In 9 out of 10 cases, booting stops at "ASRock" logo and it shows A0 code (IDE initialization). Rebooting the system does not help. Unplugging the system for a while does not help. Interestingly, clearing the CMOS does help and when the system finally boots into Windows, it works flawlessly (no drive errors, no subpar drive performance, no BSODs, no hickups)... until system is turned off (almost every time) or rebooted (sometimes).

I have already tried:

• Boot the PC with only 1 stick of RAM and without other drives


• Set CSM to disabled and enable UEFI only mode


• Disable Deep Sleep (and FastBoot) in BIOS


• Reseat the CPU, reseat the GPU, reseat the NVMe drive


• Check the power-connectors

At first, I thought it was a faulty NVMe drive, but it booted in other PCs every single time in any scenario. It is very simple - I do not want to reset the CMOS before or during every single startup of my PC. Any suggestions?]]> Tue, 12 May 2020 15:45:45 +0000 https://forum.asrock.com/forum_posts.asp?TID=14356&PID=75363&title=m2-nvme-not-recognized-on-most-cold-boots#75363
