Hi all, I have a problem with the motherboard, everything worked fine, and today is not the PC would not start. I saw that the problem is in RAM, 16GB(4x4), switched it with the help of MemOK, but only indicates that using 2 slots, and shows 8GB. I tried one by one ram and each worked well. I tried also 1-3 and 2-4 combination and also worked well. But when i throw in all of the memory, show only 2 slots to be used. I reset the bios, also tried to flash, but nothing has changed. I have no more idea. Do you have some idea. Sorry for bad english
