Hi..

I'm fairly new to the world of Overclocking and would be grateful for a little advice please.

I would like to get my E6600 2.4GHz Conroe up to 3.6GHz on an air cooling system. However, I keep getting BSODs when testing with Orthos. I don't think it's a temperature issue as when the BSODs occur, it's usually at a temperature which hasn't caused a stop error on a 3.4GHz overclock. So before I go a little mental changing voltages, some pointers would be cool.

System Info:
P5K-E WiFi
BIOS 1102
2GB Corsair DDR2 XMS2-6400C4 (4-4-4-12) (currently in black slots)
Sapphire ATI Radeon x1950 Pro 512MB
Zalman CNPS9500 Processor Fan
4 LED Case Fans
550W PSU

Idle Temp @ 3.6Ghz - 27c (Core1 32C, Core2 34C)
Load Temp at time of BSOD - 58C (Temps taken from SpeedFan and CoreTemp)

Code:
BIOS Settings:
FSB Freq = 400
PCIE Freq = 100
DRAM Freq = DDR2-801MHz
DRAM Command Rate = Auto
DRAM Timing = 4-4-4-12

Transaction Booster = Disabled
Relax Level = 0
CPU Voltage = 1.4875V
CPU PLL Voltage = 1.60V
FSB Termination Voltage = 1.30V
DRAM Voltage = 2.10V
NB Voltage = 1.40V
SB Voltage = 1.05V
Clock Over-Charging Voltage = AUTO
Load-Line Calibration = Enabled
CPU GTL Voltage Reference = AUTO
NB GTL Voltage Reference = AUTO
CPU Spread Spectrum = Disabled
PCIE Spread Spectrum = Disabled
CPU Clock Skew = AUTO
NB Clock Skew = AUTO

CPU Configuration:
CPU Ratio = AUTO
C1E, Max CPUID, Vanderpool, CPU TM, Execute Disable Bit, Intel Speed Step = Disabled
Does anything there look like it needs tweaking?

Is it likely that 3.6Ghz is too much to expect from an air cooled system?

Also, when I initially setup the system, one of the first things I did was to update the BIOS to 1102. I haven't found any reference to that version being particularly buggy but have found plenty of threads/posts where people have been far happier with earlier versions (0603, 1012 & 1013). Would it be wise to try flashing the BIOS with one of those versions? Would that help me hit 3.6GHz in a stable fashion?

Thanks for any advice possible..as I said earlier i'm a bit of a noob so be gentle with me

Cheers.
