That is normal, uninstall the other one (v17.9.1.1009) and the new one should start working...

@Fernando

That makes a lot of sense. Thanks!

@Fernando
I tried your procedure without success, the Samsung NVMe devices are definitively seen as 'not connected' after using v17.9.1.1009.
Coming back to a logical coexisting drivers (Intel RST RAID to handle a SATA RAID0 and Samsung NVMe SSDs as before installing any Intel v17.9.xx branch) is IMPOSSIBLE.
The 2 Samsung NVMe devices are 'hidden' and seen 'disconnected' (err45):

No hidden option display:


Hidden option display:


I don't see how to get back to a 'normal logical' situation.

Yes, i undesrtand your tip.
I'll try it when I get time to go back to v17.8.xx branch which is working fine on my other Z390 machine which I never been installed a v17.9.xx branch version and where Samsung NVMe drive does handle in parallel all non RAID devices.
Thanks again for your help.

@Frames
i do agree with you the Intel v17.9.xx branch driver versions are absolutely not recommendable.

Intel RST v17.9 branch drivers (for modern PCs) may be a "not bad" solution only for only very restricted configurations such as no NVMe SSDs (whatever the manufacturer are) or only for Intel NVMe RAID Array but without SATA (simple mode or RAID mode) connected devices.
I do prefer previous v17.8 branch drivers which does offer more flexibility and better performances when using proprietary NVMe drivers (for instance for Sansumg NVMe SSDs devices).

@100PIER @Fernando:

I figured it out with the help of the Station-Drivers forum. Turns out the 17.9.xx RST drivers are automatically modifying the bios settings. Here's what I had to do the fix it and get the correct drivers back for my NVMe SSD:

1. In your bios settings, under wherever your "SATA and RST Configuration" menu is (mine was under IO Ports for my Gigabyte AORUS Z390 Pro), change the option labeled "PCIe Storage Dev on Port X" (Mine is Port 9) from "RST Controlled" to "Not RST Controlled":



2. Reboot your computer. Windows won't load but we want to force it into Recovery Mode. You may have to restart it a couple times to trigger the recovery menu.

3. Once in Recovery Mode, follow the steps here to boot into Safe Mode.

4. In Safe Mode, open your Device Manager and under Storage Controllers it should now show your NVMe SSD and with Microsoft's "Standard NVM Express Controller" driver loaded:



5. Update the NVMe driver to your liking. In my case, I updated it to the modified Intel NVMe driver v4.4.0.1003.

6. Reboot into normal mode and your chosen driver should now show up properly:



You could also save yourself a few steps by configuring Windows to load into Safe Mode before modifying the bios setting.

@Fernando Intel VROC / RSTe drivers 6.3.0.1031 dated 13.02.20 can be found here- it's the complete installation package including preboot- files.

Hello everyone,

Hope everyone stay safe during this time of pandemia.

I do hope anyone can help me out.
I am having issues also with the Samsung 960 PRO 1TB not showing up on the storage controllers.

I was using the RST v17.9 Series drivers until I saw yesterday here that some were saying that it mas missing from within the Storage controller in windows, I checked and was a surprise to find out that it was missing.

I am using the current configuration at this moment:

1: Intel 900p main OS
2: Intel 750 storage

I have tried disabling my Intel optane (only reason why I use raid at this time so I could speed up my HDD) with 17.7 Series drivers and v17.8 Series drivers and still I cant manage to make the Samsung 960 PRO controller to show up.
Yesterday I installed the nvme driver 4.4.0.1003 for both my Intel 900p and Intel 750p and still can not make the Samsung controller to show up.

Either way I am going to install windows from scratch and I would like to ask some questions about all of this.

1: Which RST version does not interfere with the Samsung SSD controller?

2: I only used Intel Optane to speed up one of my HDD where most of my games are installed and I was thinking of make a RAID 0 while using my current 960 PRO 1TB and the new 970 evo pro 500GB just for that; I understand that RAID 0 is quite dangerous but since my main OS will be installed on my 900p and most of my games are saved on my NAS I should not worry if something gets corrupted as I back everytrhing.

3: Which driver works best for these 2 Intel SSD's I have got? - Either the 4.4.0.1003 or the generic 17.7 Series drivers and v17.8 Series?
I will not use the 17.9 until further notice.

4: I have also discovered that Intel MAS does not work well with 17.7 Series drivers and v17.8 Series but with the nvme driver like 4.4.0.1003 it does work just fine, it allows you to TRIM and to check for any firmware update.

Thanks to Fernando for this website anyt everyone here helping each other.
