DZ77RE-75K & HyperX KHX2133 16GB Memory Kit Issues...

hi there...

just bought the dz77re-75k and a 16Gb set of kingston hyperx khx2133c11d3k4/16gx.

no chance to get it working...just have the 3x beeps at boot-up. Post-Failure in the LED Display varies from 46-50. Memory LED in blinking fast.

unfortunately i cannot test with another ram module cause i don't have any ;-) shops are closed until monday

so i cannot update bios.

tried every bank and just one chance...

any idea? or does someone got this combination working?

best regards Julian

Hello julian,

We would like to inform you that the memory controller on the processor will support 1600MHz at 1.5V. Since the memory you are using support different XMP profiles, we recommend using the following one to ensure compatibility:

JEDEC: DDR3-1333 CL9-9-9 @1.5V

Further information can be found on the memory datasheet:

Before updating the motherboard BIOS, try this memory profile first for testing.
