@Fernando
Thanks for the extra Follow-Up - I used the driver 3.3.0.2003 - I think its the unmodified - at least the linked page I downloaded it from did not say anything about modified (I remember having seen that from a link much further up in the thread, the one I used though is from the link just couple pages prior to this).
I now downloaded the toolbox and could confirm Firmware is current - I think though I would not trust it to upgrade firmware since it identifies my Optane totally wrong with wrong size and wrong drive letters and displays my Storage Space HD 12TB set-up (used as NAS Back-up space) as a Sabrent Rocket 4.0 - who knows what that tool would try to flash. I assume the tool would do just fine in a clean Sabrent Only environment, but mixed hardware does seem to stress it out somewhat.

I did read the post originally from the beginning but not with an eye on the detailed results, more to find hints towards my original issue - I then went for the Samsung drivers based on the conclusions section that it was a driver with amoung the best performance and no hick-ups after installing it - which I can confirm, works like a charm, even on the Optane 905p drive.
Even though I might gain a couple extra percent trying some of the other drivers, I am not trying to test my luck and instead enjoy the stable fast system I now have again.
Cheers, Andreas

Hi, the Optane 905P is not the hybrid acceleration version for Intel Only - it is an Optane based NVME SSD which is available as 380 (M2 form) 480 (U2 Form) and 960 (PCIE Slot form factor) - I had a great opportunity to get one at a reasonable price from a system pull. The benefit is extremly fast small file random R/W also at low que depth (good but not amazing in sequential large files - here Rocket 4 is clearly better) and the response I am seeing in the 24 hours using it is just great - its like launching every application from a huge Ram disk - is it worth the 3x normal SSD price (or 6X without a good buy opportunity) - likely not, its more the fun of a really responsive system. To my own surprise (and initial shock) the X570 xtreme seems to be optimized to take it on. When I inserted it in the M2A slot the slot came up empty in BIOS (and it still does) - however a complete new section appeared in the BIOS showing all the Optane Drives Characteristics and only with CSM enabled it then also came up as a configurable boot drive. None of that is documented in the Gigabyte manual - hence my initial shock to have M2A showing empty just after physically installing an expensive SSD in it.
Attached the storage controller section - now shows 4 Samsung (2 Rockets, one Samsung, One Optane):

Attached a CrystalDiskMark comparison (Rocket completely empty - just wiped after moving Windows to Optane) - it does not tell the full story since the extremely low latency giving the snappy instant performance is not fully reflected by this.
Use Case ? I intend to use the Optane as System and Program drive where the strength of small file access and low latency fully shines and the Rockets for about anything else with large data files.

For better comparison to your @fernando results in the thread, here the anvil runs:

hello, how can force the installation of intel nvme driver? the version 3 is not for download

how can force the installation of intel nvme driver?

If you should mean a specific and not a generic Intel NVMe driver, you can force the installation of an NVMe driver, which natively doesn't support the specific NVMe Controller's HardwareIDs, by using the "Have Disk" option and pointing to the matching *.inf file.

the version 3 is not for download

---

Please be more precise. What ido you mean with "version 3" and why are you searching for such version?

@pipes80:
Attached is the desired 64bit Samsung NVMe driver v3.2.0.1910 WHQL for Win10 x64, but why do you prefer this driver, although a newer and probably better v3.3.0.2003 is available?

the problem comes with choosing the device, from a list of nvme intel. have to choose someone or is it indifferent?

---

It probably doesn't matter, because the INF file entries are valid for all listed Intel NVMe Controllers. While using a Samsung NVMe SSD, I always have chosen the "Intel(R) Solid-State Drive P3700/P3600/P3500/P3520/750 Series".

today testing various drivers, the nvme of microsoft, samsung and ofa, trying conquered by you i find the system no longer bootable, crashes when loading windows

---

Did you disable the "Secure Boot" and "Fast Boot" options within the BIOS and the "Hibernate" option from within the OS before you started the driver update?

@pipes80
I think you should first inform yourself and read the forum a bitt more in-depth, since it is obvious you don't even know what you are asking...

I search the intel nvme version no samsung

Which one?
Why did you change your mind? You asked >here< explicitely for the Samsung NVMe driver v3.2.0.1910.
