My overclock is stable when I'm using the pc, but if I levae it alone for more than 15-20 minutes, it always bsods and restarts. Settings are:


CPU Level Up = Auto
Memory Level Up = Auto
AI Overclock Tuner = Manual
CPU Multiplier = 8
FSB - Memory Clock Mode = linked
FSB - Memory Ratio = Synced
FSB (QDR) MHz = 1600
MEM (DDR) MHz = 1600
LDT Frequency = 5x
PCIE Bus Slot 1 & 2 MHz = 101
PCIE Bus Slot 3 MHz = 101
SPP<->MCP Ref Clock, MHz = 201
SLI-Ready Memory = Disabled

Memory Timing Setting
P1 = Auto (I will enable this when i'm stable)
P2 = Auto (I will enable this when i'm stable)
tCL ( CAS Latency ) = 9
tRCD = 9
tRP = 9
tRAS = 24
Command Per Clock (CMD) = 2t
tRRD = Auto (6)
tRC = auto (41)
tWR = Auto (12)
tWTR = auto (18)
tFAW = auto (31)
tRD = Auto (11)
tRTP = auto (6)
tRFC = Auto (88)
tREF = Auto (7.8)

Over Voltage
CPU Voltage = 1.4
Loadline Calibration = Disabled (Random bsod on idle when this is enabled, so upped vcore for time being)
CPU PLL Voltage = 1.5 (1.52)
CPU VTT voltage =Auto (1.42/44)
Memory Voltage = 1.6 (1.66/68)
NB Core Voltage = Auto (1.32. I have also set this to 1.44, same problem)

SB Core Voltage = Auto
CPU GTL REF0 Ratio = Auto
CPU GTL REF1 Ratio = Auto
CPU GTL REF2 Ratio = Auto
CPU GTL REF3 Ratio = Auto
NB GTL REF Ratio = Auto (Don't know when this is needed to be changed)
DDR3 CHA1 Ref Volt = Auto
DDR3 CHB1 Ref Volt = Auto
DDR3 CHA2 Ref Volt = Auto
DDR3 CHB2 Ref Volt = Auto

CPU Configuration
CPU Internal Thermal Control = Enabled
Limit CPUID MaxVal = Disabled
Enhanced C1 (C1E) = Disabled
Execute Disable Bit = Enabled
Virtualization Technology = Disabled
Enhanced Intel SpeedStep(tm) Tech. = Disabled
CPU Core 2 = Enabled
CPU Core 3 = Enabled
CPU Core 4 = Enabled

Spread Spectrum Control
CPU Spread Spectrum = Disabled
PCIE Spread Spectrum = Disabled
MCP PCIE Spread Spectrum = Disabled
SATA Spread Spectrum = Disabled
LDT Spread Spectrum = Disabled


So, in summary it;s stable on load, but will have restarted itself when I leave it alone for a while. Please, any ideas?
