I posted (#502) my P8Z77 experience on how to get a SM950 boot (W10 x64) drive.
Hope you finally succeed also.

Hey... you inserted the uncompressed Sonix (GUID 9A4713C2) NVMe module [b]uncompressed[/b (= normal insertion)?
Are there any differences if i insert it compressed on an ASUS Z77 board?

Do you use a PCIe 3.0x4 or 2.0x4 slot?

@pfinchen
My ASUS P8Z77-V Deluxe configuration is:
PCIEX16_1 slot for eVGA GTX 770 SC Gen 3 X16 but -> X8 due to a Dual Configuration PCIe card
PCIEX16_2 slot populated with DT-120 add in card to support SM950 PRO 512 GB NVMe boot (W10 x64) media, Gen 3 X8 -> X4
PCIEX16_3 (Gen 2) slot is populated with Silverstone ECM20 add in card to support one SM951 512 GB AHCI M.2 (X4) and one Samsung 850 EVO 500 GB SATA M.2 6Gb/s.
PCIEX1_1, _2, _3 and _4 slots are not used.

I tryed to mod the lates X79 Deluxe Bios but this didnt work out. I didnt brick the board but the Intel 750 wont boot nor would Windows install on. No boot actually worked with the modded bios not even my old Samsung 850 evo so i went back to stock.

I wonder if i should send back the 750 since i wanted it as system drive. Maybe you guys have an idea what else i could try.

Fernando,

Think you should refer to the Nvme-Express driver as the Clover team one. They deserve the credit.

great to hear :)

well you got a ECM20 too. Why do you use it not as the 'main" AddIn card for your 950 PRO? Does ist not give the full speed at PCIe3.0 ans 2 SSDs installed because of the two m.2 interfaces (bus splitted)?
I want to use the ECM20 with one single 950PRO ... is ther any performance impact to the DT-120?

@pfinchen
When I bought first Lycom DT-120 add in card Silverstone ECM20 was not available on the market !!
DT-120 and ECM20 are strictly performant equivalent.
Both are PCIe Gen 3 x4 compliant.
You can use one or other one depending on your budget.
You can use ECM20 as the 'main' add in.
Absolutely no performance impact when you use one ECM20 or one DT-120 or both of them.
The benefit of ECM20 is to offer an additional M.2 port (mechanical and power supplying) for a pure SATA III device (such as SAMSUNG EVO 500 GB M.2 SATA device).
You have to connect a SATA III 6GB/s to the SATA M.2 port on the ECM20.
Data transmission thru this SATA III cable has absolutelty no impact on PCIe bus data transmission !
There is absolutely no PCIE bus split on ECM20 !!
PCIe bus data transmission is one thing, SATA bus data transmission is another thing (cable).
So, you have the choice: one DT-120 or two DT-120 or a mix DT-120 and ECM20 or two ECM20..
The important thing is the best choice of PCIe slot where you plug in them on your motherboard.
On my P8Z77 motherboard some PCIe slots are Gen 3 some others are Gen 2 only..
On modern motherboard you have more PCIe slot Gen 3.

@Fernando, @pfinchen
I used the procedure according your guideline.
I have not tested the 'compressed' option because the 'uncompressed' option works fine for me.
I don't understand what mean "differences".
For me modding to insert a module is possible or not. It is a question with a binary response: yes or no.
May be 'uncompressed' works fine also it depends of the BIOS.
The best pfinchen has to do is try first 'uncompress', if modding does not work try 'compress'.
Usually we can observe or measure "differences" on performance aspect, but in this case 'compress' or 'not compress' has nothing to do with performance aspect.

Thank you a lot for your advice!

Following your instructions i was able to install windows 10 in UEFI-mode from an USB stick on my Samsung 951 NVMe disc.
I'm using a Gigabyte Z77X-D3H and a Delock PCIe-Adaptor.

And yes it boots from the SSD!

@Fernando,
Yes, exactly for GUID 9A4713C2
I used:
APTIO Tool v4.50.0.23, NVMeExpressDxE.ffs file.
This file is uncompressed, and I used it for normal insertion with compression option as the Aptio Tool works and does (by default I think).

Works like a charm... but i noticed that the 950PRO is not supporting Rapid Mode?!
