hi Guys been a while
 
I am after any info on the possibility of been able to boot windows from a PCIe drive, I understand that NVMe support is limited on the x79  but have reed some tales online of modded bios modules which to be honest is a little above me.
Have any of you guys tried or know of any success?

There is a guide here but since it involves modifying your BIOs I can't officially support it:
 
http://www.win-raid.com/t871f16-Guide-How-to-get-full-NVMe-support-for-all-Systems-with-an-AMI-UEFI-BIOS.html
 
Otherwise install a normal SSD if you boot from a normal mechanical Hard Drive.

i have seen that page and i am not to keen to go down that path like yourself

I am using a Samsung 950pro in one x79
And HyperX Predator in another X79
The HyperX is faster than my SATA3 6gb and the Samsung is faster than the HyperX
I did not have to do anything special to get them to work. Going to put one in my X58 Classified3 too
Find them used on Ebay or a forum to get cheaper prices, shop around.

I'll do the 950pro later, it was a bunch faster than the hyperX, the hyperx is gen2, still faster than sata3 SSD

That was from a standard sata3 spinner disk 7200 rpm
 
 

I edited that post to make it more clear that there was 3 tests with 3 drives done.
A spinner SATA3 6gb HD 7200 rpm
A SATA3 6gb SSD
A Hyperx predator PCIE SSD in an adapter.
It turned out the HyperX is around 50% faster than the regular SSD
The Samsung is just about twice as fast as the hyperx, I have to retest it, can't find the file.

This is the Samsung 950pro on my Asus x79 WS

After building my new PC, I will risk doing this BIOS mod on my Rampage IV Gene.

Check out this thread, I believe he already modded a bunch of Asus BIOS that you can download
I do believe he added the NVME info
Have to use the flashback method

Yup
Saw that when was browsing the web on this specific subject. Already saved the link.
Thanks Bill 

I just bought a Optane SSD 900P Series, Sounds like no luck in having it a bootable drive.  I really don't want to ditch the 3930K.
