You obviously confused JMicron with Micron.
JMicron and Micron are completely different manufacturers of different Storage Controllers. Only Micron is offering NVMe Controllers and NVMe drivers.]
Here is my late answer (unfortunately I missed your question):
- In January 2022 I tested the Intel RST NVMe driver v17.11.0.1000 dated 09/30/2021, because it was the latest Intel RST driver at that time.
- The NVMe performance of the v19 platform Intel RST drivers cannot be tested, because none of them supports NVMe.
- Today I have done some new NVMe benchmark comparison tests with my X570 chipset PC running Win11 v22H2 and this time I have included the latest v17 and v18 platform Intel RST drivers v17.11.3.1007 and v18.37.4.1007. The results are below.
@all
As an update of the start post I have done today some new benchmark comparison tests with my AMD X570 PC by using a rather similar configuration.
Test system:
AMD X570 chipset PC (with Ryzen 5 5600X CPU + PCIe 4.0 support) running Win11 x64 Pro v22H2 Build 22621.900, freshly installed onto a 1 TB Samsung 980 Pro NVMe SSD.
These were the drivers I have tested now:
- Microsoft’s generic Win11 in-box NVMe driver v10.0.22621.755 named STORNVME.SYS dated 11/10/2022 (the shown date is wrong)
- Samsung’s NVMe driver v3.3.0.2003 WHQL dated 01/21/2020 (installation had to be forced)
- Phison’s generic NVMe driver v1.5.0.0 WHQL dated 02/23/2018
- Micron’s NVMe driver v2.1.18.0 WHQL dated 03/02/2021 (installation had to be forced)
- Intel’s RST NVMe driver v17.11.3.1007 WHQL dated 09/30/2022 (installation had to be forced, matching are the iaStorAC.inf file and the device “Intel(R) NVMe Controller”)
- Intel’s RST NVMe driver v18.37.4.1007 WHQL dated 06/08/2022 (installation had to be forced, matching are the iaStorAC.inf file and the device “Intel(R) NVMe Controller”)
Here are the benchmark results I got:
(left/upper Pic: generic MS in-box NVMe driver, right/lower Pic: Samsung’s specific NVMe driver v3.3.0.2003)
(left/upper Pic: generic Phison NVMe driver v1.5.0.0, right/lower Pic: Micron NVMe driver v2.1.19.0)
(left/upper Pic: Intel RST NVMe driver v17.11.3.1007, right/lower Pic: Intel RST NVMe driver v18.37.4.1007)
Evaluation of my test results:
- All 6 tested drivers could be installed and used without any problems. They gave my AMD X570 PC the expected very good benchmark numbers.
- The overall performance of all tested drivers seems to be rather similar, but there are noticeable differences between the upper 2 “Sequential” (SEC) and the lower 2 “Random” (RND) Read/Write results, if you compare them between the respectively in-use NVMe driver.
- Among my test candidates the MS and Samsung NVMe drivers gave my AMD system the worst Sequential Read/Write numbers, whereas the Intel ones were the worst regarding the Random Read/Write numbers.
- So the choice of the best performing NVMe driver depends on what the user needs/prefers for his/her PC work.
If there should be interest in similar tests with an Intel Z170 PC, please let me know it.

Nice! Thanks for all your efforts!! 
Is there any driver compatible with the Samsung NVMe SSD 990 PRO 1TB?
@Dekal
All NVMe drivers, which are listed within the first post of this thread, are compatible with the NVMe Controller of the Samsung 990 Pro SSD, but the big majority of them can only be used after having forced the installation.
Here are the benchmark results I got with my AMD X570 chipset mainboard after having installed the Micron NVMe driver v2.1.19.0:
Ok. Thank you very much for the fast reply.
I would like to see the 990 Pro @ PCIe 4.0. Maybe that would be possible if I could solve the following problem…
NVMe SSD Settings
Default Settings
You have everything in place for PCIe 4.0 support (as I wrote in the other thread). Is your BIOS (Gen3 - Gen4) set correctly? Could there be a PCIe lane conflict?
For example.
Look here: https://www.tomshardware.com/news/asus-b450-x470-motherboards-pcie-4.0-support,39859.html
That’s why I want to mod the motherboard BIOS as I described in the other thread.
It was removed on later updates by new AMD AGESA implementation, what do you want mod if you cant touch the AGESA firmware.
I see no reports on latest bios versions that even with a Ryzen 5000, that the B450 will support Gen4 PCIe or M.2 PCIe Gen4.
So your stuck with a Gen4 NVMe in @ Gen3 bandwidth, the CrystalDiskMark bench numbers are correct in performance.
@westlake The publication in TOM’s is back from 2019 and no timestamp on the EDITs on that post… so for all that matters all that info on the subject suggests that was only high speculation during that period, my opinion only.
Sorry, but I still don’t understand why PCIe 4.0 shouldn’t work with your configuration. The linked article doesn’t describe anything like that, in fact it says it works.
That’s all I can add to the topic. Nowhere have I seen any comments that PCIe 4.0 is generally disabled in new BIOSes for cheaper PCHs. It is odd, though, that within a given line (e.g. B450) it works with some motherboards and not with others. Anyway, this topic is not relevant here, there is another topic for it.
In addition to my knowledge that PCIe 4.0 does not work with this mainboard when using the latest BIOS version, further statements from users of the mainboards with B450 and x470 can be found on the net, which suggest that PCIe 4.0 with the newer BIOS versions versions was really switched off again. This can also be read from the text.
Quote1:
Users today may find a PCIe 4.0 option available in their pre-X570 motherboards. However, users should expect this option to be disabled when final retail BIOSes are released to implement full performance and stability for new 3rd Gen Ryzen processors.As pre-X570 motherboards were not designed with PCIe 4.0 in mind, their designs may be incapable of running PCIe 4.0 signaling with the requisite stability and performance. To ensure a reliable and consistent experience in the field, PCIe 4.0 will not be an option ultimately available to pre-X570 motherboards. Users may continue with a beta BIOS if they desire, but performance and stability cannot be guaranteed.
I haven’t seen this said beta BIOS until today. Even a request from Asus for such a BIOS has not been successful so far.
Quote2:
Edit: These BIOS revisions will likely be used widely to unlock PCIe 4.0 on these motherboards, but to retain that functionality, you will not be able to update to newer firmwares in the future that lock out support. That means you’ll eventually lose out on the performance-boosting BIOS updates that AMD is known for.
These statements are very speculative. But there is also a direct answer from AMD on the net, which clearly proves that PCIe 4.0 has been deactivated again for these chipsets.
For me this is known. I know how to evaluate the benchmark values correctly.
MeatWar is most likely right. But let’s discuss this further in the thread I opened:
I’m not giving up on getting a BIOS MOD just yet.
I ran 2 different benchmarks in CrystalDiskMark.
1.) In the “Settings” menu, selected “NVMe SSD” + Benchmark
2.) In the same menu “Default” + Benchmark

Thank you very much for your quick reply. Your information was very important for me, because I hadn’t yet realized this specific CDM “Settings” option for tests with an NVMe SSD.
As a result of your useful post I have instantly done some new CDM tests with my Samsung 990 Pro and got nearly unbelievable results:
Maybe I should do some new performance comparison tests with the optimized CDM settings.

You’re welcome! 
Here I have a few more registry entries for unlocking settings in the Windows power options.
So one can better tune/test the SATA/NVMe drive.
NVMe Registry Settings - Power Plan.rar (5.5 KB)
EDIT: I think these settings only work when using the Windows driver, but I don’t know for sure.

With modern Windows Operating Systems it can be done much easier by doing a right-click onto the “Start” button and choosing the “Power Options”. Look here:
Interesting. Is that Windows 11?
Even if I hardly expect any performance differences, I would like to install a different driver for my Samsung NVMe SSD 990 PRO 1TB for testing. I want to test the Phison and Micron driver…
Currently, my system boots in non-RAID mode using the Windows Storage driver. AMI Native NVMe Driver Support is enabled in the BIOS.
What is this option for anyway?
What confuses me a bit is the following…
To find out whether a specific “Storage Driver” will work with your currently in-use AHCI/RAID/NVMe Controller, you should extract the downloaded driverpack, open its *.INF file(s) by using any text editor and looking for matching VendorID (VEN_xxxx) and DeviceID (DEV_xxxx).
Both a different VendorID and DeviceID are displayed in the device manager. Is it still safe to test these drivers? Or could it happen that Windows no longer starts?
@Dekal
Yes, I am running Win11 Version 22H2 Build 22621.1192.
Just to show, that a Samsung 990 Pro SSD user cannot expect huge performance differences by changing the in-use NVMe driver, here are the benchmark results I got with my AMD X570 chipset system.
These were the drivers I have tested:
- Microsoft’s generic Win11 v22H2 in-box NVMe driver stornvme.sys (wrongly dated 06/21/2006)
- Samsung’s NVMe driver v3.3.0.2003 WHQL (dated 01/21/2020, install has to be forced)
- Intel’s RST NVMe driver v17.11.3.1007 WHQL (dated 09/30/2022, install has to be forced)
- Phison’s generic NVMe driver v1.5.0.0 WHQL (dated 02/23/2018)
- Mikron’s NVMe driver v2.1.19.0 WHQL (dated 08/03/2021, install has to be forced)
Here are the benchmark results I got:
To prevent any problems while trying to change the in-use NVMe driver I recommend to set a Restore Point before starting the tests. Don’t try to delete any storage driver!
