Q9650 Overclocking Advice

I'm hoping someone can help me. I've had my Q9650 CPU for several months and I decided to try overclocking it. From reading different websites I got the impression it would not be difficult to get it to 3.6 GHz stable by just increasing the FSB. Here are my specs:

MSI P45 Neo 3 motherboard
Samsung M378T2863QZS-CF7 1GB X 2 DDR2 RAM
Windows 7 64-bit
Hard Disk 250GB
NVIDIA GeForce GTX 285
Corrsair TX750W PSU with 60A on a dedicated single +12V rail

Here are the settings I have in the BIOS:

Multi-step OC Booster - MODE 1
D.O.T. Control - Disabled
Intel EIST - Disabled
Intel C-STATE Tech - Disabled
Adjust CPU FSB Frequency (MHz) - 400
Adjusted CPU Frequency (MHz) - 3600

Advance DRAM Configuration - Untouched
Enhance Setting - Auto
FSB/DRAM Ratio - 1:1:00
Adjusted DRAM Frequency (MHz) - 800

Clock Gen Tuner - Untouched
Adjust PCI Frequency (MHz) - Default
Auto Disable DRAM/PCI Frequency - Enabled

CPU Voltage - 1.33 - 1.36
DRAM Voltage - 1.90 - 2.00
MCH Voltage - 1.10
VTT FSB Voltage - 1.25
ICH Voltage - 1.50

Spread Spectrum - Disabled

My PC is able to boot to Windows with no major problems. However, if I run Prime95 or OCCT one of the cores will cause a hardware error and will fail the test. I have increased the CPU voltage as high as 1.36 and Prime95 can make it to the 5th Test before there is a hardware error. Do I need to add more CPU voltage, or am I overlooking something else. The CPU temperatures seem fine judging from Core Temp.

Any advice would be appreciated.

Try adding a bit of MCH voltage...

Check out the overclocking guide in my signature...

Like ED mentioned, increase the MCH voltage to ~1.34V, CPU voltage to 1.35V, and ICH voltage to 1.55V. VTT FSB Voltage should be fine at 1.25V and a FSB of 400MHz, but manually adjust the four primary timings to 6-6-6-18 and 1.8V (or whatever timings and voltage the modules are rated at).
