ustech@gskillusa.comDear Customer
I can surely help you get your system running properly. The issue you were having is insufficient QPI/VTT Voltage. Although the XMP detected memory settings, the CPU voltages to sustain an overclocked CPU were not embedded in the XMP profile. As a result, manual voltage setting is needed.
With the XMP profile, simply set QPI/DRAM Voltage to 1.60V for DDR3-2000. In order to operate DDR3-2200, it may require slightly more than this so you will need to test for the lowest voltage. Note that you will need to watch CPU temperatures as it can get quite hot with these high voltages. For DDR3-2000+, we suggest aftermarket CPU coolers.
BIOS should look similar to the following:
In MIT (MB Intelligent Tweaker):
CPU Clock Ratio - 21x
QPI Link Speed - AUTO
Base Clock Control - Enabled
BCLK Frequency - 143
Performance Enhance - Standard
Extreme Memory Profile - Disabled
System Memory Multiplier - 14
Uncore & QPI Features
Uncore Frequency - 4000
DRAM Timing Selectable - Manual
CAS Latency Time - 9
tRCD - 9
tRP - 9
tRAS - 24
Enter these for the other three as well.
Channel A Timing Settings
Advanced Timings
Command Rate - 2
Advanced Voltage Control
Load-Line Calibration - Disabled
CPU Vcore - 1.32V
QPI/VTT Voltage - 1.60V
CPU PLL - 1.900V
PCIE - AUTO
QPI PLL - 1.300V
IOH Core - 1.400V
ICH I/O - 1.600V
ICH Core - 1.300V
DRAM Voltage - 1.640V
Rest to AUTO
Let me know how that goes.
Thank you
