Sabertooth x79 Slot DIMM_D1 not working.

[Dawnde]

Greeting,

I just upgraded to 64GB of Corsair Vengeance Pro Memory 64GB Kit 8 (CORSAIR Vengeance Pro 64GB (8 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model CMY64GX3M8A2400C11R)

(Pervious RAM kit was a 12GB Corsair Vengeance 4x4x4.)

I understand that the board is rated lower and purchased this speed for scalability.

I have tested all eight sticks in all 8 slots. All memory registers in BIOS in all the slots but DIMM_D1. I even have other types of memory I have tested in this slot and it does not even register.

SABERTOOTH X79 BIOS 4801 (is current version running)

Processor is a Intel i7 3930k.

Does anyone have any ideas?

Respectfully,

Dawnde

Might try raising the VCCSA voltage to 1.2 , which can occasionally help , but sounds like a dead slot
