2 x Cubix Xpander problems or MB

Hi Everyone,
I got two Cubix Xpander that are attached to my Motherboard (ASUS X99A - 5960X and 64GB RAM).
No matter what I do my system fails to boot with more than 5 GPUs.
I got 1 x 1080 connected directly to PCIe in Motherboard.
I also tried to connect just one Cubix and use the other PCIe Slot on MB for other 1080, but even then the system boot fails.
Could it be the motherboard restriction?
Is there anything in BIOS I have to change?
Please help.
Thanks

hi there
I've already responded on facebook group to Your question, but try to go thru bios options or manual & see if You can find 4G option to enable. Some ASUS motherboards have this & usually it solves the problem. Let us know how that goes =)

How did you go??
In the bios do you have these 2 options? -
MMIOH Base =???
MMIO High Size = ???
Along with above4g what are those settings?
When i got 8 running in my supermicro my settings had to be
MMIOH Base = 512G
MMIO High Size = 256G

Hey Tom,
Yup that's me, I tried to change the username here... it's not some seduce the nerd strategy

Hi elisabettagiovi,
Did you solve your problem?
If you have not solved with 4G, could you kindly make a test?
Could you remove a video card and put your GTX1080 in xpander?
Everything works correctly?
Let me know about this, please.
