[Crashish]

System Details:

• Motherboard - Gigabyte GA-MA790XT-UD4P (BIOS F6)
• Memory - F3-12800CL9D-4GBRL - Retail
• CPU - AMD Phenom II X3 720 Black Edition Heka 2.8GHz
• Operating System - Windows 7 Ultimate Edition x64

Additional Information:
According to Newegg & CPU-Z specifications, this RAM should operate at 1.500V; However, 1.600V is the motherboard's default DRAM Voltage; 1.600V is the lowest possible voltage.

Current Memory Timings:

• DC Mode - Unganged
  
• DRAM Frequency - 669.7 MHz
• FSBRAM - 3:10
• CAS# Latency (CL) - 9.0 clocks
• RAS# to CAS# Delay (tRCD) - 9 clocks
• RAS# Precharge (rRP) - 9 clocks
• Cycle Time (tRAS) - 24 clocks
• Bank Cycle Time (tRC) - 33 clocks
• Command Rate (CR) - 1T

Current Memory Voltage:

• DRAM Voltage - Normal (1.600V)

Thanks for the quick reply.

Would you mind giving me the rest of the timings (in orange)? Not only will this help me, but I think it'll help many other people with the same hardware.
