My opinion it is a good idea to re-add the Intel NVMe drivers v3.2.0.1002 WHQL to the start post. It is a quite stable version and performant version.
If you look at in detail the ATTO test result, there is a severe performance issue for v4.0 version (I have paint in yellow the abnomaly).
This issue is permanent and can reproduce easily. I have done the test multiple times under W10 RS3 and W10 RS4.
I don't understand the source of the problem.
If you have the opppotunity to test on your machine this will definitively demonstrate that it is a pure driver issue.
Coming back from V4.0 to v3.2.0.1002 WHQL on the same machine I no longer get the abnormal low performance really visible for the user.
For instance a system (i750 device) backup operation is significantly longer when using v4.0 version.
May be v4.0 is optimized for new Intel SSD, but for old Intel SSDs device Intel NVMe v3.2.0.1002 does offer performance and stability.

@soupiraille
Is it possible for you to post the ATTO bench result for your Optane 900P ?

Sure @100PIER. I re-did the ATTO benchmark for v3/v4 just after a fresh Windows restart (in my previous test, I didn't do the v3 ATTO bench after a fresh restart), now the results are roughly the same.

v3.2.0.1002


v4.0.0.1007

Thanks @soupiraille . The ATTO results are quite perfect for the both Intel NVMe drivers versions driving your performant 980 SSD model.
The v4.0.0.1007 problem for i750 SSD model does remain a myster for me.
So, I do use only v3.2.0.1002 at the moment.

@100PIER > by the way, if you read previously, Intel has silently updated the NVMe drivers v4.0.0.1007 on 04/25/2018, while keeping the exact same version number. So if you still have the February v4.0.0.1007 version, it may be worth trying the April v4.0.0.1007 (which is on the first post of this very topic or here).

Thanks @soupiraille , in fact i used the latest v4.0 version modded recently by Fernando.
I have downloaded few minutes ago the version Client x64 version offered on Intel site and installed it, rebooted the PC, and started ATTO bench.

Definitively this v4.0.0.1007 is a disastear for my i750 400GB device as you can observe the huge abnomalies (yellow):

-for Transfer Size > 4 MB the Read and Write performances are a disastear.


So, definitiveley I forget this v4.0 branch which does seem optimized for Intel Optane SDD devices only !
Nota: for small transfer size this device does offer better Write performance than Read performance.

Hi

I have a HP Zbook G3, I am looking to install win 7 64bit, via SCCM 2012 R2, all I am looking for is a driver that actually works with these drives, so I can load win 7 onto it, is there an actual extracted driver that works ie contains the .inf and .sys file, the .exe is no use, I have any tried so many methods to make this work but nothing seems to help.
any help appreciated

Cheers
Paul

Hi Fernando

first of all thank you for replying very grateful.

I am building the Hp zbook G3 via SCCM 2012 R2 and every time I build it cannot see the drive, I believe I need a NVMe driver so it works write after the build, apparently like many people the problem is first to get the install to see your NVMe drive, then the next issue is to stop it blue screening after its built, I have checked logs in the client as in smsts.log file and all I have is, I think I need to interject different drivers into the build so it stops blue screening

Shellexecute raserver failed. 0x80070002, but I think this is red herring

Cheers

@Fernando,
I have tested Intel NVMe driver v4.0.0.1007 BUILD_2 WHQL offered on by Intel (27april18).

It is a disaster when driving a i750 NVMe:


I highly do recommend to use v3.2.0.1002 for non Optane Intel SSD devices.

Hello, could somebody please help me with my doubt? I have a motherboard (http://www.asrock.com/mb/Intel/Fatal1ty%20P67%20Performance/) mounted on an old PC, for which I'd like to replace the HDD with a brand new 860 EVO SSD, but I don't know which SATA port and driver I should use.

It has x2 SATA3 managed by Marvell controller and x4 SATA2 managed by Intel chipset. My question is: should I use the Marvell SATA3 or Intel SATA2? Also, can I use Intel RST drivers on the SATA3 ports instead of the Marvell drivers?
