My asus board RAM settings are as follows:
In the BIOS, go to ADVANCED, then CHIPSET. When you're there check to see if yours is the same as mine, which is this:
Configure DRAM Timing by SPD : Enabled
Performance Acceleration mode : Auto
DRAM Idle timer : Auto
DRAM refresh rate : Auto
That's the way mine is, and once again, the components in the actual stick didn't make a difference with mine, in fact they are different brands as well. Hopefully that can help you out!
