Overclocking Intel Core 2 Quad Q6600

[MatressGiant]

SUMMARY:

I am in the process of attempting to get a little bit more out of my CPU.
The CPU and cooler are from 2008 and the GPU is from 2009. All other items were from 2011 (MOBO, PSU, RAM).
I have recently cleaned out my case, etc. for noticeable temp drop (few degrees C).

Let me know what if any additional information is required.


HARDWARE:

CPU: Intel Core 2 Quad Kentsfield Q6600 HH80562PH0568M
(according to CPU-Z Stepping B Revision G0)

MOBO: GIGABYTE GA-P45T-ES3G LGA 775 Intel P45 ATX Intel Motherboard
Link to manual: ftp://download.gigabyte.ru/manual/mb_manual_ga-p45t-es3g_v1.3_e.pdf OR http://www.gigabyte.us/products/product-page.aspx?pid=3857#manual if that doesn't work.
Also note that the BIOS in the manual is not EXACTLY the same as mine. I think the one you see is either the most updated version or for a SLIGHTLY different board. Its just to give you the main idea of how it looks.

RAM: G.SKILL 8GB (2 x 4GB) DDR3 1333 (PC3 10600) F3-10600CL9D-8GBNT

GPU: EVGA 896-P3-1265-RX GeForce GTX 260 Core 216 896MB 448-bit GDDR3

PSU: CORSAIR Enthusiast TX750 V2 750W ATX12V v2.31/ EPS12V v2.92 80 PLUS


CURRENT SETTINGS:

Refer to page 33 of the mobo manual if it helps (there are pictures).

CPU Clock Ratio: [9X] (was at 8X)
Other settings in this category: Auto/Default

***Clock Chip Control***
CPU Host Clock Control: [Enabled]
CPU Host Frequency (Mhz): [333]
Other settings: Auto/Default

***DRAM Performance Control***
Performance Enhance: [Standard] (was at Turbo. Can't overclock hardly at all with this set to Turbo, aka slight RAM overclock?)
Other settings: Auto/Default

***Mother Board Voltage Control***
CPU Vcore: [Auto] (I tried changing this to normal, which would be 1.325v, but got an error on one of my cores after some hours of stress testing. Auto works with no errors, but my CPU reaches temps of 59° C w/ Auto Vcore of 1.360-1.392v (according to CPUID HW Monitor, which always has a lower Vcore value than in the BIOS settings. EX: If I set Vcore to 1.325v in BIOS it will say its 1.29v or something like that.))
Other settings: Auto/Default


QUESTIONS:

Obviously I could set my Vcore manually to a value higher than 1.325v until I get a stable voltage, but are there other BIOS settings I should be altering?
Should I be messing with the other voltages or changing anything of the RAM settings, voltages?
Should I be changing any of the settings from default in the Advanced BIOS Features page? (refer to page 41 of the manual for picture)
Am I doing something wrong?

Any and all comments and suggestions are appreciated.

CPU Cooler: ARCTIC Freezer 7 Pro Rev.2 with 92mm PWM Fan

EDIT:
I went through this whole guide before making this post: http://www.tomshardware.com/forum/259899-29-core-overclocking-guide

I am currently running 3.05 GHz with a Vcore of 1.375v (CPU-Z claims its 1.296-1.312v) with no errors.
I am going of the assumption that < 65°C is probably okay based off said guide (One specific test got temps up to 63°, but Cores 0 and 1 average at 59° under full load and don't go above 59° during practical use. Cores 2 and 3 are almost always 3-7°C lower than Cores 0 and 1).

Still looking for anything that could help me keep my temps down, settings to tweak, thoughts, comments, suggestions.
