For a start a big thanks to the people involved in modding the Z9PE-D8 WS bios enabling bifurcation - Its working well so far.
As for the next headache. I need Bifurcation on a P9X79 LE.
Is Bifurcation even possible on the LE? As I have only seen Bios done for the ws or deluxe.
Or should I just get a different 2011 socket motherboard?
Thanks for any assistance.
@WalkerCorp - Great to hear the Z9PE BIOS is working well for you! 
See post #2 for BIOS you wanted here - [Request} Need BIOS Dump from Someone for P9x79LE
It’s stock BIOS Mod, so flash ONLY using USB Flashback
Two drives now showing in slot 1 and 4 of a 4 way nvme pci-e card. The fact that slot 4 is working I would assume 2 and 3 will if ever need.
Big Thanks.
@WalkerCorp - You’re welcome!
No, all Asus X79 can only use x3 NVME, some BIOS bug or something, all models are affected from what we’ve seen in testing, unsure if anyone tested LE about this, but I assume same as all the others.
If you do end up testing with 4 NVME and it works, let us know, thanks!
