MSI X99A Gaming 7 RAM issue

[FLACS]

Hi There,

I'm facing system boot issue (cycle cocde 19 B0 55 19)

If i boot with one 8 gb RAM stick it boots and works perfectly, and then i swap with 4 8gb stick it works.

 

But if I use all 8 * 8GB RAM stick (64gb total) it cycles 19 B0 55 19 and do not boot, sometime i have remove one random stick it works or two random sticks it works.

This my system Spec

CPU: Core i7 5820K (NOT OVERCLOCKED)
RAM: Corsair Vengence LPX 64 GB (each 8 Gig Kit) (XMP off)
GPU- Titan X (Maxwell) (NOT OVERCLOCKED)
Motherboard: MSI Gaming 7 X99A
PSU:  Corsair HX1200i

Please, anyone, tell me what would cause this issue?
