This is my PC Specs - https://www.youtube.com/watch?v=k9jTesHddgU as you can see its running at 1333 Mhz, I just got new ram today that can run up to 2400 Mhz without overclocking it & the ram I did have ran at 1333 Mhz, I have tried changing it in the bios & I don't know if I am doing it wrong or not but it either freezes at the windows logo or I just get a black screen & have to turn it back to auto which makes it 1333 Mhz, I have tried it with 1866Mhz & 1600 Mhz & the same thing happens, Any help on this? Much appreciated
I think you can't run a 2400MHz ram on a FX cpu. The highest you can get away is 1866MHz. If you want stable system, turn it up to 1600MHz and increase the voltages with the smallest increment. Tradesman1 will give a better answer than mine.
