I've also tried to manually update via device manager, but I get the message that the drivers for the device are up to date. Any ideas?

Microsoft win 10 Nvme driver is good enough for SM951 nvme, so why change?

Or is this not good enough?

Those results are using default Windows 10 driver but you have 'Turn off Windows write-cache buffer flushing' enabled correct?

That is not considered ideal, the Samsung NVMe (950 PRO) driver works perfectly with the SM951 NVMe and does not require this setting to be changed smile.gif

Have had no issues installing the Samsung 1.0/1,1 driver by simply execution the .exe file with administrative privileges...

Hey there, just came to share my experience with 256 nvme on a Gigabyte Z97 SOC FORCE.

On a side note, I bought a cheap ($6.85 shipped) pcie adapter and it's just perfect. With the drive at €129, that was the cheapest significant upgrade I ever made.

I had W10/64 installed on a sata SSD, CSM on, MBR. Cloned the drive twice for safety : Windows Image and acronis 2016. Burnt 2 uefi boot cards (CF on USB3 reader) for these tools (from W10-th2 iso, not the original one). Samsung nvme driver in both of them, just in case. I had tested the drive before and I confirmed that the Windows driver does hinder performance.

In Bios, disabled csm, put boot mode to "w8" and secure boot on. The cheap adapter card lets the bios detect the drive as nvme and pick it for boot.

Windows install boots from CF UEFI. Starts copying files at CF speed. Select the Samsung driver and create a simple GPT volume from scratch. Will repartition later for multiboot and such. Then the magic begins... before I know it, the windows desktop appears and it's doing its update thingy, already whining about activation. new side note : I entered my old w8 upgrade key, all good. Check Samsung nvme driver still loaded.

Reboot on Acronis UEFI card. Restore in file mode -NOT FULL DISK, leave EFI partition alone ! Reboot on Windows install disk, go to command line and do the diskpart and bcdboot things to fix the c: drive letter and point to the efi partition. Done, I converted my old windows install to uefi, which was only needed for booting from nvme. They won.

The improvement in boot speed is noticeable (already was stupid fast anyway) but day to day operation is a lot smoother. After repartitioning and pointing my browsers profiles to the m2 drive, I can tell when firefox starts up with all its tabs and extensions loaded. I used to leave it opened at all times, not any more. A lot smoother. Windows operation feels somewhat better too. I did a HDsentinel read test. That was funny...

This drive is indeed hotter that the hard disks or even the MX100 but the case has good air flow. I make sure to close the side panel and check fan operation. So far, idle is at 32 (24 in the room) load at 40. 45 max in lifetime (24 hours) but I installed Windows with panel opened, hence no fan.

Conclusion, I'm a happy camper, that was a well spent €135. Only disappointment is that Samsung software doesn't like the drive, pretends it's OEM, which is weird since I bought it in a store. No firmware upgrades on such new tech is not good by my standards. But i expect this first large scale nvme drive to only be the first in a fast growing series and soon be outperformed until those 4 pci lanes are the bottleneck. Then what ? a X16 lanes adapter for $ 6.85 ?

Me liky cheap upgrades: strong the cheap (and force) factor was with this one.

I'm not entirely sure what secure erase actually is, but would sdelete -z (or any other utility that can write zeroes) do the same thing ? i did a quick HDsentinel surface test on my 256 nvme and all affected sectors did display nothing but zeroes. Is secure erase something different ? I know next to nothing about ssd's so that might be useful info to me. Thanks.

No, not the same sadly.

Thanks. That was interesting. I understand the main issue to be wear leveling.
I really need to look on how ssd controllers work, as I sense a significant shift in data security here. Surprised I didn't pick on this before. Never too old to learn smile.gif
Thx again.
Edit:
Now I'm double disappointed not to have access to the Magician util. Nasty Samsung.

Monitoring.
I found a couple of questions about temp monitoring on this drive, since the Samsung software is not supported.
I have Hard Disk Sentinel. Since v4.70 or so, SM951 is supported, provided the Samsung driver is installed.
http://www.hdsentinel.com/revision.php
Checking on the fan cooling efficiency in a small atx case, I did a couple of fan 100% adjustments (front and then side) with the drive in idle state and ran crystaldiskmark once I found which fan was which smile.gif. The graph ends with side fan being returned to normal mode (50%).
The drive is mounted on a pci-e adapter, the side fan is not straight on top of it but close enough. both fans are 120mm PWM. It appears that the front fan, cooling the hard disks bay does drop the idle temp but to a lesser extent than the side fan. It's probably good enough, even at 50%, to prevent load overheating and throttling. The side panel fan is merely a nice to have and will remove even chances of high temps at sustained loads.

Hello,
I just made the downgrade asus x99 de luxe bios 3101 to 2001 for me the most stable and efficient,
as with samsung 951 ahci I have problems to restart the pc hangs just load the drivers in windows in the post asus UEFI
however, beyond that with the 3101 performance in overclocking fell and I had to raise volts for both cache per processor not to mention the ram that no longer support overclocking to 2666
we await the next bios this is indecent for my components
any of you encountered these problems?

I'd like to ask you if you have any idea or tip, what else can i try.
The thing is that 2 months ago when i posted that benchmark was working better than now.
For example if i had :
seqQ32T1 = 2000, now i have arround 1850
or
4kQ32T1 = 720, now i have arroung 590-610.

It's quite some new, fresh install of windows 10 64bit, all i was playing arround was loading applications and few drivers , while i was figuring out,
why i have some problems while playing audio, cause i have computer for music producing.

What i have already tried now is,
-tried samsung drivers, 1.0, 1.1, default windows drivers, results are the same.
-updated chipset drivers and other system drivers, results shows that all drivers are updated and fine

Maybe settings in Bios ? before i'll load defaults in bios , i'd like to ask here first,
maybe it's software issue, or bios , or ...
any tips and suggestions are welcomed smile.gif

best regards
