Have you tested your memory with Memtest86+?? Memtest86+ - Advanced Memory Diagnostic Tool
You may need to raise the DRAM CTRL REF Voltage and or DRAM DATA REF Voltage value by a notch. I'm no AMD expert but the values should actually be a multipler and by increasing it you should be increasing the voltage to the memory controller. You may have to adjust these values for each memory channel being used.
The ram your looking at is even faster than the memory you have so I think you'll probably have the same problem.
Can you post a screenshot of HWMonitor
so we can see some voltage and temperatures?
And can you post a few screenshots of CPUID
The CPU, Memory and SPD tabs?
