  • Help! F-3 12800 CL7D with Asus M4A79XTD EVO DRAM timing/driving configuration

    I'm waving the white flag. I'm over my head! ! I am trying to setup the DRAM timing/driving configuration for my new system, and I need help figuring out what to do.

    Motherboard: Asus M4A79XTD EVO
    Bios version: 0605 Build date 09/21/09
    CPU: AMD Phenom II X4 965 processor running XP Pro

    Here is the information in the bios that I need help with, this is in DRAM timing/driving configuration portion of my bios. Each of these items needs a setting. I am happy with what ever help anyone can give me. Thank you.

      uscool,
      Thanks for the bios tip. I upgraded and did the following from from G Skill:

      Dear Customer

      Simply set memory timings as follows:

      TCL 8
      TRCD 8
      TRP 8
      TRAS 24

      Memory Frequency DDR3-1600
      Memory Voltage 1.60V

      Once that is complete, everything should be fine. The reason why you can not use the rated timings is due to a BIOS limitation.
