AMD A10-7870K 2400MHz Ram Problems

[wiculek]

Hello, my pc specs are:
-G.SKILL 8GB 2400MHz TridentX CL10 (2x4096)
-Gigabyte GA-F2A68HM-DS2 (A68H PCI-E DDR3)
-AMD A10-7870K 3.90GHz 4MB BOX
-Corsair CX500M 500W Bronze BOX
I've bought this set like 2 months ago, but from the beggining I had one problem - When I set Ram to 2400 MHz, the computers crashes after few minutes of usage of graphics card, like games or test programs. I've tried changing Ram Voltage, CPU Voltage etc, but it still doesnt help. Sorry for bad english, it's not my native language

Not all motherboards can handle 2400mhz RAM as it is technically overclocked. Some can't handle 2133mhz RAM.

When you go on the motherboard's spec sheet on the manufacturers website is your RAM kit listed?
