Thanks for the confirmation Fernando, I will try again.

I Have a Intel S2600CP and added NVME support by adding NvmExpressDxe to the bios, however after each reboot I get stuck on the Windows Logo, right after it's initializing usb devices etc. If I then reset the system it gets stuck during post (Can't enter bios etc). Bios is set to UEFI Mode only for the record.

However if I remove the power from the system and do a cold boot all works again. I tried disconnecting all USB devices and other PCI slots but it's always the same.

Any one encountered this before?

How did you flash the modded BIOS? Are you really sure, that the flashing procedure has been successful?

Dunno about that hardware in particular.
Anyway, some cheap M.2 adapter uses the wrong path on the PCI-express causing all sort of issue till the impossibility to shutdown the system ( mainly duo the USB routing )
If you made the correct changes, EG: you made the right DXE dependency over the driver ( if required by the bios format ) then remove any other PCI-ex card from the board and try a know adapter.
If nothing else, update the XHCI driver. Be aware that you will likely lose the S3/S4 state.

If the installer is letting you select the NVME disk: the driver is loaded correctly.

Anyone ever here of the Asus P9X79 WS/IPMI motherboard? I got one on the way but now realize it is slightly different than the rest of the P9X79 series boards and has a third Ethernet socket for remote management. I am assuming the bios modules may be different than the standard and i have yet to find this board ANYWHERE on the Asus website. I would like to modify this bios for NVMe support but would like the latest bios in it.

I have a Supermicro X9DRi-LN4F+ motherboard and I have modified the BIOS with the first NVME option and successfully flashed it.
The device shows up as P ATA SS: in boot, perfect.

On my X9SRA motherboard i had to select "Windows Boot Manager" to get my board to boot from the NVMe drive. If i study the POST screen the actual model of my SSD shows just before boot starts as well.

Hello everybody! First of all, i want to say Thank You to Fernando for his amazing job and more importantly for his personal TIME that he is spending here helping people. Secondly, i wanted to report that i finally recieved my adapter(Jeyi SK9 pro from Aliexpress) and 960 evo 250gb version(from local store). I followed all the instructions and successfully made my 960evo a bootable device on Asrock Z77 Extreme4 motherboard(on my first try! :)). Everything works perfectly, expect the fact that I'm getting half of a queue depth(4k q32t1) speeds. After that, I followed ALL the instructions in "How to boost the AHCI/NVMe performance of Intel Chipset systems" thread, reinstalled Win10 twice, reinstalled AHCI and NVMe drivers and etc., but unfortunately nothing changed. Here is my CrystdalDiskMark 5.1.2 results.

Sequential Read (Q= 32,T= 1) : 3220.901 MB/s
Sequential Write (Q= 32,T= 1) : 1398.198 MB/s
Random Read 4KiB (Q= 32,T= 1) : 326.525 MB/s [ 79718.0 IOPS]
Random Write 4KiB (Q= 32,T= 1) : 262.842 MB/s [ 64170.4 IOPS]
Sequential Read (T= 1) : 1974.741 MB/s
Sequential Write (T= 1) : 1389.528 MB/s
Random Read 4KiB (Q= 1,T= 1) : 44.498 MB/s [ 10863.8 IOPS]
Random Write 4KiB (Q= 1,T= 1) : 151.206 MB/s [ 36915.5 IOPS]

Test : 1024 MiB [C: 53.5% (124.2/232.2 GiB)] (x5) [Interval=5 sec]
Date : 2018/02/16 18:31:44
OS : Windows 10 Professional [10.0 Build 16299] (x64)

I would appreciate any advice and help. Thanks in advance!

Why you don't use CDM v5.50 or better CDM v6.0 tools ?

With 960EVO 250GB you should obtain less performance than with a 500GB model as specified by Samsung.

I didn't use CrystalDiskMark v6.0 because all of the benchmarks(on the internet) of 960 evo(250 gb) were done using older 5.1.2 version. So i used 5.1.2 for direct comparison. Here is my results. I used all the programs that you used
