Answer 1

You are trying to run XMP profile memory which is meant for Intel systems and not AMD. Courtesy of Hardware Canucks, the explanation is a s follows:

By now, we should all be used to Intel’s Extreme Memory Profiles (XMP) which basically sets aside a pre-selected space within memory modules for specific SPD profiles. This benefits everyone from overclockers to novices as it gives them pre-defined values for specific usage scenarios.
Following in Intel’s footsteps, AMD has now introduced Black Edition Memory Profiles or BEMP. While BEMP certainly doesn’t have a particularly sexy ring to it like XMP, its functionality is virtually the same and can be controlled directly by the user. One of the main differences between XMP and BEMP is the way profiles are stored; XMP uses a portion of unallocated space within the modules themselves, AMD’s solution uses online profiles for the memory. This allows for the memory manufacturers to add additional profiles once their products have shipped but it also means BEMP is tied at the hip to AMD’s Windows-specific Overdrive utility. Once set up properly, these memory modules will effectively increase memory frequency, lower timings and bump the Northbridge frequency for additional performance.
You can try and manually find memory settings that will work, but I shall refrain from guaranteeing stability.
For a start I would use only one module and set the DRAM ratio manually so that your mem runs at 1066. Suggested timings as per the JEDEC#2, i.e 8.8.8.22. You should be OK with the CR at 1 at 1066 but you may have to change that to 2. Start your OC attempts from there and let the mem gradually increase as you increase your FSB/HTlink. Once your mem gets closer to 1333 change the timings to 9.9.9.24 as per JEDEC#3. You can also use those timings right from the start to avoid any instabilities as the DRAM freq increases from 1066 to 1333.
