I'm trying to make my system run properly, but in no case I can make my ram modules to run at 1600mhz. Already changed both modules. I cannot reach speeds over 1280 and SPD infos show 1333. System crashes before bios screen if upper speeds are set. Please tell me something.

This is my configuration:
Model Name : GA-X48T-DQ6
--------------------------
M/B Rev : 1.1
BIOS Ver : F4 (F4H already Tested)
Serial No. : SN081100054828

-------------------------------------------------------------------------------
VGA Brand : GALAXY Model : 8800GTS
CPU Brand : Intel Model : Q6600 Speed : 2400MHZ
Operation System : VISTA64BIT SP :
Memory Brand : Corsair Type : DDR3
Memory Size : 2X1GB Speed : 1600
Power Supply : 750 W


ddr3 modules: 2x CM3X1024-1600C7DHX

some pics assembling the system following.
Use the PINK DIMM Slots &
Try these settings for a start:

CPU Clock Ratio = 7x
CPU Host Control = Enabled
CPU Host Frequency = 400MHz
PCI Express Frequency = 105MHz
Performance Enhance = Standard
System Memory Multiplier = 4.00D
Memory Frequency = 1600
DRAM Timing = Manual
CAS Latency = 8
RAS to CAS Delay = 7
RAS Precharge = 6
tRAS = 21
tRRD = 7
Rank Write to Read = 7
Write to precharge = 7
Refresh to Act = 72
Read to precharge = 7
Static tREAD value = 7
Static tREAD Phase Adjust = 0
CMD = 2N
DDR3 Overvoltage = +0.3V
FSB Overvoltage = +0.2V
MCH Overvoltage = +0.3V
Loadline calibration = enabled

And place a fan above the memory to keep them cool.
Let me know if it worked for you.
