    Intel DH87RLwith 16 GB Kingston Memory KHX1600C10D3B1

      Hi,

       

      I have an Intel DH87RL Desktop Board with a 16 GB Kingston Memory Kit KHX1600C10D3B1K2/16G. This is a kit of two KHX1600C10D3B1/8G modules. The KHX1600C10D3B1/8G module is listed on the tested memory list from Intel for the DH87RL with module speed 1600 MHz(see http://www.intel.com/support/motherboards/desktop/db-dh87rl/sb/CS-034215.htm). The full specification for the kit is: Kingston HyperX Blu DDR3 16GB Kit 1600MHz , 2x 8GB, CL10 (10-10-10), 1.5V, 240Pin. The board is updated to the latest BIOS Revision 323 (RLH8710H.86A.0323.2013.1204.1726).

       

      How do I properly set the BIOS so that the memory runs at 1600 MHz (2*800) DRAM Frequency?

       

      BIOS memory settingMHz in BIOSMHz in CPU-Z
      Automatic1.33*10 = 1333661.1
      XMP-1600 Profile1.33*12 = 1600661.1
      Manual (increase 10 to 12)1.33*12 = 1600799

       

      Using "XMP-1600 Profile" does not work. (Is this a bug in the BIOS?)

       

      Using "Manual" works, but which values do I set for all the many other settings? In CPU-Z it is shown as 9-9-9 which is above the specified 10-10-10.

       

      The SPD has the following timing tables:

      JEDEC#4XMP-1600
      Frequency685 MHZ800 MHZ
      CAS# Latency9.010.0
      RAS# to CAS#910
      RAS# Precharge910
      tRAS2527
      tRC3436
      Command Rate(empty)(empty)
      Voltage1.50 V1.500 V

       

      Thank you for your help.
