Help! Need to overclock my E 6400 and dont have a clue.

I am attempting to breath new life into my sysem, so I got an eVGA 8800GTS and some more, faster RAM, and sinse Gigabyte just unlocked my mboareds overclocking features with their latest BIOS I also would like to pump some more juice out of my CPU to go with the uogrades.

RAM: CORSAIR XMS2 (2 x 1GB) DDR2 800 (PC2 6400)4-4-4-12

CPU: Intel E 6400 with a thermaltake cooler. idels at 25 and load at 34

I found someone had posted an excellent guide with a system very similar to mine only hid ram is slower, sinse I dont understand the basics of overclocking maybe someone can be kind enough to run the figures and tell me what numbers to change?

7. Enter the MB Intelligent Tweaker (M.I.T.) section and do the following:
- Set CPU Host Clock Control to Enabled
- Set CPU Host Frequency (MHz) to 376
- Set PCI Express Frequency(MHz) to 100
- Set System Memory Multiplier to 2.00
- Set DRAM Timing Selectable to Manual
- Set CAS Latency Time to 5
- Set DRAM RAS# to CAS# Delay to 5
- Set DRAM RAS# Precharge to 5
- Set Precharge dealy (tRAS) to 12
Most RAM will actually work at 4-4-4-12 but this is a guide for lazy people so I figured I'd go with 5-5-5-12 since it's bound to work.

I would love to get my processor to 2.9 but would be satisfied with 2,6. Thanks for any and all help!!!!!!
