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 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-ZAutomatic1.33*10 = 1333661.1XMP-1600 Profile1.33*12 = 1600661.1Manual (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-1600Frequency685 MHZ800 MHZCAS# Latency9.010.0RAS# to CAS# 910RAS# Precharge910tRAS2527tRC3436Command Rate(empty)(empty)Voltage1.50 V1.500 V
Thank you for your help.
The following documents may help you setting up the memory in BIOS:
http://www.intel.com/support/motherboards/desktop/sb/CS-020304.htm Desktop Boards; BIOS settings glossary
http://www.intel.com/support/motherboards/desktop/sb/CS-031689.htm Desktop Boards; Performance tuning guides
I managed to set the properties for the memory as follows:
- select the "XMP-1600" profile
- select "Manual"
- Save and Exit
Now the values as shown in the column "XMP-1600 (> Manual)" in the table below are active and also shown in CPU-Z.
The board runs stable with this settings.
I still think it is a bug in the BIOS that the settings cannot be done with the steps 1 and 3 only.
(I am no interested in overclocking the system/memory. I only want to run the memory with the tested settings from the manufacturer.)ProfileAutomaticXMP-1600 (> Manual)Frequency MHZ13331600TimingstCL910tRCD910tRP910tRASmin2427tRFC174208tRRD45tWR1012tWTR56tRTP56tRC3336tFAW2024tCWL78tREFI52006300Command Rate20 (CPU-Z: 1T)AdditionaltRRSR44tRRDR66tRRDD66tWRSR1820tWRDR55tWRDD55tWWSR44tWWDR77tWWDD77tRWSR910tRWDR910tRWDD910Dec-WRDXX
