Hello Fernando

I tried to install windows starting from the usb, in bios I only appear the usb or dvd. And when I try to install no unit appears to me.

As for what we talk about replacing the Body of nvmeexpress, I must extract the body when I have the cursor on nvme. Or should I just replace the pe32image section?

When I look for Nvme through uefitool, I count entries in:
DevicePathDxe, Dxe driver
Setup, Dxe Driver
Nvmeint13, Dxe driver
Nvme, Dxe driver
Nvmesmm, Smm module

With only the nvme replacement, Dxe driver should recognize the samsung 960 Evo.

I'm trying to asus, give me some solution to my probema.

Thank you.

You think I'd learn my lesson and stop trying to install NVMe drives on older motherboards. :) Here's my latest challenge.

Gigabyte GA-B75M-D3H Motherboard
SilverStone ECM20 M.2 Expansion Card - Plugged into the one PCIe 3.0 x16 slot on the motherboard
myDigitial SSD BPX 120 GB NVMe SSD - Inserted into the 'M-Key' / PCIe Ms SSD slot on the Silverstone Card.

I was able to update the latest BIOS for the motherboard and insert the uncompressed NVMExpressDxE_2 module as directed in the intial post and flashed the motherboard. After that, I was able to install Windows 10 Pro to the NVMe drive (in UEFI Mode) and it boots without a problem. My issue is, I'm not getting the speeds I should be getting. The 120 GB drive should be able to get about 2300 MB/s Reads and 1200 MB/s Writes but I'm only seeing about 1300 MB/s Read and 900 MB/s write.

I did turn off the Windows write-cache buffer in the drive policies, but not sure what else I could try. Anyone have any thoughts?

What PCI-E slot have you installed the card into? You say its first and only one 16x slot? Could be the card not wanting to go into pci-e 3 mode. Some firmwares might default to 2.0 speeds on older hardware. Not much you can do.

For those struggling to get NVME working on the Gigabyte GA-Z87X-UD4H, here is my little contribution to this thread

==> Gibabyte GA-Z87X-UD4H NVME bios (based on 10p)

This is a fully-working-modded BIOS, based on Z97-related one, without support of wake on lan features, in order to get space for NVME-related code. I run it with a samsung 960 evo 500GB, placed on second PCI-E slot (to get 3.0 support and the 3GB/s of read-bandwitdthd).

Done, thanks for advise

Hi guys, I´m so frustrated cause this works for me before, but now I can not make it work . This is the problem:

I did a formatting of m.2 for reinstall windows 10, everything ok, but the big trouble is that i can´t boot in UEFI mode. The big and disturbing message appears again and again NO Booteable device is dectected. System will enter the bios Setup Utility. So I try CSM enabled and SS PATA: appears in boot menu, I setup windows 10 but the installation won´t start, the next message appear 'Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure the disk's controller is enabled in the computer's BIOS menu. Ok I reset the PC, select UEFI compatibility but I can´t access to the disk always say the same thing No booteable device Found.

I reflashed bios 2 or 3 times, I try in different pci-exp ports, but nothing work. Just say No booteable device Found. So sad
please help me thank you guys

Today I did the mod and it works with my Samsung 960 Pro 512 GB NVME drive and Asus Maximus VI Extreme mobo! I was busy so I couldn't do it sooner.

Thanks for the excellent guide and caring more than the actual mobo manufacturers to get NVME working properly on older mobos!
