Hi,
I'm building my new computer and I think I'm having compatible issues between my motherboard and my RAM.

The computer doesn't boot at all and I can't access the bios. On the motherboard, the DRAM Led Red Light is opened. I read it's an issue with the RAM.

In my motherboard's manual, it's says that I need 4 memory sticks of the same kind if I want to reach 2400MHZ.

As I wrote in the title, I have a Sabertooth 990FX R2.0 Motherboard and Corsair Vengeance Pro Series 16GB (8x2GB) 2400MHZ.

I can't find the problem.

FX CPUs have weak memory controllers. What CPU do you have? They are rated at up to 1866MHz memory. It is next to impossible to run 4 sticks at higher than 1866MHz. FX CPUs have enough trouble with running two at higher than 1866MHz much less four. Try one stick, then two if you can get any stability. You're gonna have to OC the CPU too, to run memory faster than 1866MHz.

EDIT:
According to Asus, that board supports up 1866MHz memory with the right CPU.

+1 Spooky nailed it What CPU? Is it OCed? Might start at 1600 and try to get them working at that prob 9-9-9-27 1.55, if you can get them stable, then try 1866.....let us know what you try (timings/freq/voltage and we can go from there
