Help overclocking e8500! - Overclock.net

So it's been a while, by a while I mean I can't even remember the last time I o'ced my system. My mobo caused everything to run hot so I could never o/c but now that I got a new mobo, cpu and ram and I want to o/c again.

These are my system specs...

Win 7 Pro X64
Gigabyte EP45-UD3R
Intel Core 2 Duo e8500
Xigmatek HDT S1284 Heatsink
GSkill 2x2gb DDR2 1066 PC2 8500
EVGA Nvidia Geforce 8800GTS 640MB (might upgrade soon)
Cooler Master eXtreme Power RP-600-PCAR 600W (might upgrade soon)
Cooler Master Cosmos Case

I currently have 3x 1200rpm coolermaster fans (I think the cfm is something like 40) which I am going to replace so I can get more airflow. There is 2 at the top blowing out, and 1 at the bottom blowing in. I plan on getting 4 of these http://www.newegg.com/Product/Produc...82E16835185060 (2 top - exhaust) (1 rear - exhaust) (1 bottom - intake)

I currently idle at 23c and max load at 40c after about 10 minutes. This is with the side doors off and it is around 65F room temp right now. I think the new fans should help it stay at these temps with the side doors on.

I really just need someone to help me go through the bios and let me know what needs to be changed and to what. Any help would be appreciated, thanks!

increase vtt a little, increase mch to 1.24-6 or so and LOWER gtlref values. Once you figure out the gtlrefs that work you should be good
