Please help Fernando, I'm going to upgrade my SSD for bootable OS, but I don't know witch one is working the best for my MB Asrock X79 Extreme9 and CPU Xeon E5-2667 v2 ES LGA2011. Should I buy XP941, SM951 NVMe (AHCI hard to find, was replaced by NVMe on the market where I live) and I prefere 950 Pro NVMe, but will it work for my MB ? Do I have to flash modded BIOs (Please link me to how ? I'm a newbie to this). By reading all the posts..is it true that my MB does not support NVMe ? is there any modded BIOs that can make it to supports 950 Pro NVMe..? I already bought the PCI-E 4X for M.2 SSD ADAPTER card. Thank you..Any suggestions are welcome...Please.
Kind regards. Jen

Thank you very much for your help and fast respond..I'll learn how to flash modded BIOs.

hi everyone

I have the P9X79WS and Zotac Sonix pcie 480MG Nvme , recognizes , but does not let me boot with Win 10.
I have seen that you can update the bios , I could help with that.

thnkss you

Hello, guys. Searching about NVMe devices I have found this forum. I see you have gather a lot of knowlage and I hope you will be able to enlighten me.
I have an Asus B85PRO-Gamer motherboard. I have also ordered m.2 to NVMe adapter and think to buy some m.2 SSD like A-Data SP550 240GB(yeah i know its tlc). My questions are do you know if this motherboard support booting from NVMe or I will need to modify the BIOS. Also will there be any difference in read/write speed when using a regular m.2 drive with NVMe adapter? Thank you in advance.

Hi, thanks for replying. This is the adapter I have ordered -> https://www.aliexpress.com/item/JEYI-SK7...2663265346.html . And I really have no idea if A-Data SP550 have legacy mode or not as for my bios. And I want to use it under Windows 7 as I have seen some videos and guide that it is indeed possible for Windows 7 to boot from NVMe, but it was a samsung one...
P.S. So if I understand this correct there are regular m.2 drives(designed to be used on m.2 slot) and m.2 drives designed for NVMe? And if I used m.2 device designed for m.2 slot it won't make any difference in speed even using it with an adapter over PCI slot?

I have a doubt... I have flashed a modified BIOS file with the NVMe modules with the AFUWINGUI aplication, checking the "Recovery" option for step a "18 - Error: Secure Flash Rom Verify fail". I rebooted the PC, and when I open AFUWINGUI again and click "Save" for verify if the new BIOS has the NVMe modules incorporated, I can not find them. How can I be sure that I have correctly flashed the new modified BIOS and it has the NVMe modules incorporated?

I have tried to flash the BIOS with the ASUS USB BIOS Flashback too, because the ASUS EZ Flash give me an error "Secutiry verification failed" and when I go to verify with AFUWINGUI I still can not find the NVMe modules in the BIOS file. I need to be sure that I have flashed correctly the BIOS.

After 3 days of following this guide, learning, testing, switching and changing, I finally installed a bootable Windows 8.1 on a OCZ RD400 256GB on my ASUS Sabertooth X79 and got the fastest System I've ever seen! Thank you so much, Fernando and the others, for working out this great guide. Toshiba itself claims that on X79 this Drive could not be booted and as I saw that ASUS did not update BIOS Versions since 2014, I nearly gave up hope...

I did not read all 60 pages of this Thread, but I had some struggle while trying this: every time, I changed the CSM settings to UEFI Boot, there was only a black screen, so I later found out that this setting is unimportant. I had to add the Patition Table to the drive with gparted and no other way worked.

Here my benchmark result:

Another, maybe easier method would have been to create the bootable USB Flash drive containing the OS image by using the tool Rufus and to choose the "Partition Scheme" option "GPT Partition Scheme for UEFI".

I mean adding a GPT Table to my SSD. But I have to say I had another working Windows Installation which I booted inbetween and while booting there was every time a scan on this drive and that changed the partition of the SSD. In gparted I could see then a small system partition on this drive. Creating the installer-stick with Rufus went fine by the way :)
