RAM: 2x 8GB set Crucial Ballistix Sport DDR4 BLS8G4D240FSA
Motherboard: AsRock Z170 Extreme4
Processor: Intel i7-6700k
RAM and motherboard are compatible in dual channel according to here. However, whenever I place both sticks of RAM in dual-channel placement, the PC fails to boot even into BIOS.
The motherboard has the four memory ports, from left to right: A1 A2 B1 B2
The following combinations give:
A1 A2 - PC boots normally. 16GB of single channel RAM.
A1 B1 - PC fails to boot. Dr Debug displays error code 4C.
A2 B2 - PC fails to boot. Dr Debug displays error code 4C.
B1 B2 - PC boots normally. 16GB of single channel RAM.
Single stick in A1 or B1 or A2 or B2 - PC boots normally. 8GB of single channel RAM.
The problem obviously does not lie with any one memory port or stick, but rather with the dual channel arrangement.
Any suggestions as to the cause and/or solution? Thanks.
EDIT: I have tried Tradesman's suggestions of raising the DRAM voltage to no effect. I have also tried reseating my CPU and checked for bent pin without any luck.
