Those are the EPP profiles for the memory.

http://en.wikipedia.org/wiki/Enhanced_Performance_Profiles
Enhanced Performance Profiles (EPP) is a memory technology for PC's delevoped by NVIDIA, primarily designed to make overclocking easier. It is a feature of the nForce 5 and nForce 6 chipsets. Corsair, along with NVIDIA, were the primary parties in developing the specification.

EPP will likely be available only for DDR2 memory modules. It requires support of both the motherboard and the memory module. It uses unused space on the SPD. EPP handles many factors, including memory timings to potentially improve performance. Data can be used by the motherboard's BIOS to automatically configure the system. EPP can handle clock speed, CAS latency, tRCD, tRP, tRAS, memory voltage, and command rate. In addition, a fully enhanced profile will be able to handle drive strengths, fine delays, setup times, write recover time, and tRC. It can also enable the user to overclock the computer's CPU and memory at the same time.

NVIDIA's name for EPP memory that has been qualified for performance and stability is "SLi-ready memory".
You can try different timings, but might need to increase the voltage to the memory.

Watch your subtimings...if it sets the bottom three to 10-10-10 you are going to have to discover them with Memset. Asus boards aren't reading several brands subtimings correctly when you go to "manual" on RAM timings. On auto it reads the SPD correctly apparently.
