E6600 + P5W Overclocking help needed please !

[villain1]

I have my e6600 +P5w running stable at 3.0 ghz but no matter what i try i just cannot get it running stable any higher.
Can anyone with similar setup help me get stable at at least 3.2 ghz.

CPU Model: E6600
CPU Vcore: Auto
Multiplier and FSB used: 9 * 333
Clock Speed: 3000MHz
Dram Freq: ddr2 833
Motherboard: Asus P5W DH
RAM: 2Gb GSkill HZ PC2-6400

MCH Chipset Voltage: 1.5
ICH Chepset Voltage: 1.05
Method of Cooling: Zalman 9500

I am new to overclocking so might be something simple i am missing here,i am raising the fsb and upping the cpu vcore volts but just cannot go any higher.

Thanks for any help you can give.

Ive managed to run orthos for 8 hrs without fail at 3.20 by upping the ram voltage to 2.15 and changing the ram settings to 5-5-5-15.
My only concerns are my temps were peaking at 60 deg after 8 hrs of orthos and at around 40 idle.
I have an Antec p180 case along with a zalman 9500at cooler on the CPU which has been treated with AS5.
Are these temps to high for everyday use ?

Managed to lower vcore slightly and now in orthos is at load between 50-55 deg which i am happy with.
Have now managed to break the 16000 barrier in 3dmark05


Thanks all for your help
