Hi, I have been getting stability issues (crash with very little stress) when booting with memory upwards of 1800Mhz on my i7 920, through a 180 bclock and 20x multi. Turbo OFF, HT off.
I have the same settings as proposed on the UD3 motherboard, expect for the specific memory timings (in red), which, when inputted manually caused the computer to crash. I did not pin point which of all, if not all the settings caused the instability, and the baseclock & cpu multi (in blue). I am currently running a stable
In MIT (MB Intelligent Tweaker):
CPU Clock Ratio - 20x
QPI Link Speed - AUTO
Base Clock Control - Enabled
BCLK Frequency - 180
Performance Enhance - Standard
Extreme Memory Profile - Disabled
System Memory Multiplier - 10
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
tRC - 27
tRRD - 4
tWTR - 4
tWR - 8
tRFC - 60
tRTP - 4
tFAW - 20
Command Rate - 1
Round Trip Latency - 42
Advanced Voltage Control
Load-Line Calibration - Disabled
CPU Vcore - 1.30V
QPI/VTT Voltage - 1.55V
CPU PLL - 1.900V
PCIE - AUTO
QPI PLL - 1.200V
IOH Core - 1.400V
ICH I/O - 1.600V
ICH Core - 1.300V
DRAM Voltage - 1.640V
Rest to AUTO
Thx for the advice.
