memory specification for my motherboard is 2 x DIMM, Max. 8 GB, DDR3 1800(O.C.)/1600(O.C.)/1333/1066 ECC,Non-ECC,Un-buffered Memory. It was working fine at 1866mhz but unfortunately it has stopped working and it now only working with 1333MHZ.I have also tried new RAM of 1866mhz and 1600mhz. Can anyone suggest me what is the solution so that it could work with higher frequency as before
