How's that? I think I got it ... hopefully :)

@Fernando
2 FFS file including compressed. I can not say what kind of assembly, and whether it will work. Unfortunately I did not check, because there is no correct controller and the disk.

Found EFI AMI NVMe Driver GUID 634E8DB5-C432-43BE-A653-9CA2922CC458

Quick question,

I have seen two ways to add NVME support. The first (yours) is to add the the module from the first post. The second is to pull three NVME related modules from a Z97 BIOS, and insert those. I was wondering if there is a difference in the result of the two methods?

I am trying to add NVME support to a ASrock z77 Extreme9 with an i7-3770k, in order to add one of the new 600p SSDs. Thanks for all the work you have put into this!

So these NVME drivers are basically proprietary and they can't be touched or edited, is what I think you told me.

I appreciate the response :) and it's good to know if that's the case. This way I don't go and do something stupid - and believe me, I am the dumb.

I added a module "NVMeExpressDxE.ffs" Dell Precision T5600.
Boot works well. But speed is not perfect.


1. Samsung sm961 256gb nvme installed gpu second slot. PCIe v3 x16.
2. Windows 10 1607 64bit GPT uefi and samsung nvme driver.
3. Bios settings: Intel SpeedStep and C-States control disable.
4. Write caching enabled and write-cache buffer flushing disabled.

Can someone help?
The problem is: 4K Q32T1 test

EDIT by Fernando: Attached picture optimized and reinserted as 2 "screenshots"

I have tested various installations:
1. clean Windows installation, samsung driver and nvme slot is "PCIe v2 x8" seq speed of about 1500MB / s
2. clean Windows installation, samsung driver and nvme slot is "PCIe v3 x8" seq speed of about 2500MB / s
3. clean Windows installation, samsung driver and nvme slot is "GPU slot4 pcie v3 x16" seq speed of avoit 3300MB / s

All the same problem. Q32T1 4k read / write speed. about 150 MB / sec -- 200MB / sec. :(
My graphics card is slot2 pcie v3 x16.

Today we make a new test.
screen controller "slot2 v3 16x" and nvme "SLOT4 3v 16x" ---> Cross ---> display driver "SLOT4 v3 16x" and nvme "slot2 v3 16x"

and a clean installation of the drivers.

same problem. 4k Q32T1 is very slow.

I have not tried without a graphics card.
this is not integrated graphics.


I tried without a graphics card.
I was using Windows Remote Desktop.
No effect on performance :(

Both cards:
sm961 nvme 128GB and sm961 nvme 256GB. The same problem "4K Q32T1" is 150MB / s - 200MB / s.

Hi guys.
I have made a regristration to that site because I have a simple question for you.
I bought a Samsung 950 Pro 512gb for my new PC that mount what i've written in my sign here. The MoBo I've chosen is the Asus H170 Pro Gaming.
I have been googled that thing but i've read that this SSD works only with Z chipset or in other forums also with my MoBo. In one of them i saw a link to an Asus site into wich it seems that on my MoBo (H170) this 950 Pro works at its full potential. So, is that real or I've made a mistake?

Please let me lnow what's the truth :)

My Asus ROG Z170 has NVME support. I don't know about plain boards.

It may be possible, that ASUS inserts the required EFI NVMe module(s) only into the BIOSes of their Z170 Chipset mainboards, but I think, that you will get the Samung 950 Pro SSD working with your H170 Chipset system as well.
My tip: Open the latest BIOS for your mainboard by using the AMI Aptio V MMTool and check, whether there are NVMe modules in it.
If yes, the Samsung NVMe SSD will be bootable from scratch, if not, you will have to insert the required NVMe EFI module according the start post of this thread.
