Since the memory controller is built into the processor it will support DDR3-1066/1333/1600 rated at 1.5V. Please make sure to run memory with such specifications to narrow the issue properly. Test with minimum memory installed as well and ensure your power supply is higher than 450watts. No BIOS update is required for this kind of issue.
it goes working me around the correct with the xmp profile.
that is everything.
the memory works however max. with 1866mhz and not with the xmp profile (2133mhz).
