And thanks very much to @Fernando for all the help and for providing some updated driver for us with this OEM Samsung thing! You're my hero!

Yeah, yeah! I read that thread too, but it didn't work for me, unfortunatelly. I changed the lines in the file, like someone explained and all (even cared to change the line that would corrspond to my 256 ssd), but I've got a greyed update button. So I am still researching how to do it. Dell could simply release a software for that and simplify life for us.

Just feed back about the correct driver for the Samsung PM981: the one that works for me is the "Dell Express Flash NMVe PM1725 1.6TB PCIe SSD Controller". Other ones I tested made my Start Panel work incorrectly. I hope it helps you people that have the same SSD.

Hello,
I would like to ask what driver to use for Patriot Scorch 256GB nvme drive with Phison® 5008 controller? Thank You.
edit:
So since there is no advice, I helped myself. I measured performance in CrystalDisk Mark and Generic OFA NVMe driver v1.5.0.0 and Standart Nvme driver in Windows have the same results. In addition, after installing the OFA driver, my disk mounts as removable which I do not want. I have tried Intel NVME and it has problems, so I am happy with the standard nvme driver.

@Fernando . There is no other site like this one. And you are one of a kind sharing your hard work.

Thank you for sharing with us your drivers.

Can you recommend me a driver, please? What is the best NVMe Controller Driver? I get increased error s.m.a.r.t values on the latest win10 builds.

Really thankful that Lost N Bios did a bios mod for me. :)
System Asrock x79 Extreme 4 and latest Windows 10 build.
MP600 Corsair. NVMe
NVMe is new bought two recently. One MP600 and one MP510


Because on the latest Windows 10 build 10.0.18362 Version 1903 (May 2019 Update) the Error log in the Smart Options "Number of Error Information Log Errors" increases everytime i restart the pc. and only when I force to restart it. (Taskbar > Restart).

Then I noticed when switched back to Windows 10 build number 10.0.17134 aka Redstone 4 the "Number of Error Information Log Errors" does not increase anymore.
Also tried Windows 8.1 and the count does not increase as well.

I can pinpoint it to Win10 build Version 1903 (May 2019 Update) and Version 1809 (October 2018 Update).

(I also observed that on the windows version which do work and the count does not increase every time I reboot. The application HD Sentinel was unable showing driver information. on both win10 and win8.1
On the Windows version where the count increased there is driver information hd sentinel was able to display. By that I mean the status of the SSD was known. Maybe just a coincidence )

I was even thinking about copying the stornvme.sys driver from version 10.0.17134 to the latest win10 build Version 1903 (May 2019 Update) which is producing me strange "Number of Error Information Log Errors" everytime I reboot.
But in these case I would have to sign it.

What your take? Should I try it or could you please recommend me a driver. I am willing to test and report back.

Because seeing the "Number of Error Information Log Errors" Count increase everytime I reboot makes me depressed. Not knowing the reason why.
I get these error on both ssds and only on these two windows versions Win10 build Version 1903 (May 2019 Update) and Version 1809 (October 2018 Update).
I also noticed slower performance (longer loading times) in games there.

Hello Fernando,

you are correct, i tried importing the 17134 driver onto the win 1903 OS. Well it does boot successful but has the same behavior.

I am also speculating that it is not NVMe Driver related but could be any other system32/driver interfering. Because Like I said it does not happen in the previous windows versions. How can one explain that?.

I briefly tried the OpenFabrics Alliance Driver they do not work. Windows doesn't boot. the .sys filenames are also different and do not match with standard microsoft nvme driver.

Dear Fernando,
I am having an issue installing the "64bit OFA NVMe Driver v1.5.0.0 for Win7 x64 mod+signed by Fernando.rar" in Windows 2008R2 sp1.
I have repeated a few times and verified the Win-RAID CA exists using Certmge.msc before installing.

Following the guide I installed the Win-RAID CA Certificate and rebooted.
Checked the Cert.


Then installed your signed OFA NVMe Driver, however I get an error 52 - "cannot verify the digital signature".



What could I be missing???

Thank you Fernando for explaining once more. Didn't event went to bed. Because if the m2 is faulty I can still send it back and get.my money back.
It was really pricey
I did all these steps before. Got the matching 64bit drivers
After the reboot i see the Windows Logo but then abruptly that loading circle stops/freezes.
Could you please link me to the v16 driver. I did try the x79 Enterprise drivers without success
I disabled driver enforcement via gpedit and cmd this i can rule out

@cstang67 if you dont care you ciould try disabling it altogether.
(Windows is telling that it doesnt see the cert, i guess)

StormRaider,
Thanks for the tip...
I was able to install the drivers, however after reboot it starts up in recovery mode.....
So I guess the OFA drivers do not work with 2008R2...
The Microsoft NVMe driver Hotfixes for Win7/Server 2008 R2 on Page #2 does work with my new MVMe PCIe adapter.
After reading the NVMe performance thread I was going to test the OFA drivers...

Thanks again

StormRaider,
I can confirm that I also see "Number of Error Information Log Errors" increase on every boot also.
I believe they increase with the Microsoft Hotfix drivers and for sure using the Intel drivers I just installed from page #1. I learned from one of the threads that the intel drivers work for all SSD's so I edited the .inf file and added the PCI/VEN code for my Sabrent 256gb ssd. Installed fine...

@cstang67 Thank you very much for letting me know.
You also get these? So, this is indeed strange. I can assure you this increased count does not happen on Win8.1 latest Final build and Windows 10 build number 10.0.17134 aka Redstone 4.
And where these happens I observed I got lower loading times performance in games (e.x Just Cause 4)
@cstang67 a thought comes to mind.
"however after reboot it starts up in recovery mode." somehow your windows is refusing too boot in test mode even with driver enforcement disabled.

I am pretty sure it is OS dependent. And it is indeed not the nvme driver at fault like Fernando wrote. it is some different .sys driver interfering. (found in C:\Windows\System32\drivers)
If I find a workaround for Windows Server 2008R2 I will let you know. I used to use this OS back in the day.
I am also on a PCI-E Adapter card because my x79 motherboard Asrock extreme 4 does not support it out of the box.
I tried different nvme card like the asus hyper m2 but I got the same results.
Wondering what Fernando's reply will be.

//I was not able to install the OFA NVMe driver v1.5.0.0 I will give it another try.
Fernando are you sure it doesn't matter that the original file is called stornvme.sys the filepackage of OFA NVMe driver v1.5.0.0 does not contain a file called stornvme.sys

Keeps increasing like Hell? Can this value be ignored at all? or is a function having trouble executing? Like SSD TRIM?


//Fingers crossed:



restarting now.

//edit no luck keeps freezing the loading circle just freezes. It stops.



Restoring now.


Any Idea what to try next?
