Please help with overclocking q9450 on an Asus P5N-D

Hello, I am new here and was wondering if you could help me out with the problem I am having. I have a p5n-d (750sli) board. I am running gtx 275 sli and I just got the q9450 as an upgrade from E5300 clocked to 3.3mhz. So far I had no luck at running at anything but the stock speed. I have tried many different set ups that people have tried on the forums and nothing has been succesfull. I have 8gb DDR2 Ram. If you know what to do please help. Here or some options
Vcore - ?
Dram Voltage - ?
HT Voltage- ?
NB Chipset Voltage- ?
SB Chipset Voltage- ?
FSB Memory clock mode - ? (tried linked most of the time)
Memory Ratio - ? (tried 1 to 1 and sync)
Do I do anything in the chipset options?

Thanks for your help

PS. I have just tried
Vcore - 1.32500
Dram Voltage - 1.910
HT Voltage- 1.32
NB Chipset Voltage- 1.40
SB Chipset Voltage- Auto
FSB Memory clock mode - Unlinked (1600 for FSB and 800 RAM)
Memory Ratio 1 to 1
I also disabled all the CPU options where Multiplier is and I put 5-5-5-15 ram setting in the chipset menu


My Specs Are:
Windows 7 64bit Home Edition
Q9450 CPU
P5N-D Mother Board
Corsair TX 950 non modular PSU
Antec 902 Case
Xigmatek HDT-S1283 CPU Cooler with a the backplate mounting kit
DDR2 8gb of RAM running at 667.0 MHz according to system info from 3d vantage test software.
