didn't work the drive keep disappearing didn't like that riser card oh well should have bought a Samsung live and learn

Hi Dieter,
i have a Samsung PM981 and i don't find your modded driver 2.3.0.1709 (your post #933)
In first page there is 3.1.0.1901 (official) and 2.0.8.1611 (modded). Which of them can i use?
Another question. If i install one of these driver, can i install latest version of samsung magician software?
Because i read that PM981 is not supported and it works with old version.
Thanks in advance

Hi Dieter,
I would like to test the OFA NVMe-Driver on my test-PC (AMD, FM2+, Win10 Pro x64)
Do those driver works with AMD and Samsung NVMe?
Thanks a lot.

Hi Dieter,
yes, it works, but on my pc it's a little bit worser then the Samsung-driver; have a look at the pictures.

Hi Dieter,

First of all, I don't use Intel!
My platform is AMD FM2+, one with A10-7890K/Asus A88X-Pro, which is my work-computer, and one with A10-7850K/G1.Sniper-A88X, which is my test-PC.
Even though I tried to follow your advice-list:

1: SSD connected trough PCIe on 3.0 x8 (work-PC) and on x16 (grafik-slot, test-PC).
2: Firmware is updated on both SSD
3: Not done, on both BIOS should be C6-Status
4-5: OS fresh installed, partition/format done with install routine (autounattend.xml)
6: No missing driver, OS up to date
7: Not done, but the drive is detected as SSD on AS SSD and Samsung Magician
8: Last NVMe-driver from Samsung
9: Tried, but no difference
10: No LPM on AMD (or I didn't found it)
11: Not yet tried
12: No Intel
13: Done, but no impact on benchmark
14: Anvil say "No device responded to TRIM-command, Samsung Magician says "TRIM Status aktiviert" and "Optimierung" works.

8: NVMe-driver from Samsung (last one)

Hey all..

i had a Problem with TRIM. I had a ASUS TUF B450-Pro Board und 2 SSDs (Muhkin Triactor 3DX and Western Digital 1TB)
With both SSDs will TRIM not Work.



Driver is AMD AHCI 1.3.1.277. Test it with MS Driver the same.. Installed Win10 fresh without any Driver. Trim will not work.

I hope anyone can help me.. Thx

@Fernando
Both SSD should be bad????
I can't believe it!
Both computer works properly and I do not have a more modern HW, sorry.
to a):
Work-PC, Win7, ASUS A88X-Pro, 2xPCIe 3.0 (x16 or x8 if both in use), CPU is FM2+ A10-7890K (for 3.0!), discrete grafic R7-250, Samsung 970 EVO Plus 1 TB on kryoM.2 evo card, NVMe protocol 1.3.
CrystalDiskInfo says: Transfer Mode 3.0 x4 actual, supported 3.0 x4.
AIDA64 detects the grafic-bus as 1.1 x8 (idle) and 3.0 x8 (load).

to b):
Test-PC, Win10, Gigabyte G1.Sniper A88X, 1 PCIe 3.0, CPU is FM2+ (A10-7850K), NO discrete grafic (only APU), Samsung 960 EVO 256 GB on kryoM.2 card, NVMe protocol 1.2
CrystalDiskInfo says: Transfer Mode 3.0 x4 actual, supported 3.0 x4.
AIDA64 detects the grafic-bus as integrated, idle or load.

Have a nice week !

@Fernando:
Issues are solved!!
Problem was the StoreIM Driver.. Back to MS.. now all ok

EDIT by Fernando: Unneeded fully quoted post replaced by directly addressing (to save space)

How do I roll back to the native Win 10 x64 driver from the OpenFabric? I switched to the latter and find the performance to be less.
