Overclock E8400 to 3.7GHz {+Help} (Stable at 3.6GHz thanks to you guys)

[IRoHellsing]

Sup guys, I am here once again to ask for help to increase my overclock just a little bit, 4months ago you guys helped me to set my E8400 stable at 3.6Ghz and a few days ago i've bought 2 new sticks of memory Corsair Dominator DDR2 1066Mhz (Sold the old Kingston DDR2 800Mhz) and now i want just to get Stable at 3.7Ghz w/ my E8400 and 1100Mhz w/ the memory.

Detailed information about my computer:

Intel Core2Duo E8400 C0 @ 3.6GHz {400x9} 1.26850v + Cooler Extream Ice Cube SF-901 w/ Artic Silver 5
Motherboard Gigabyte GA-EP43-DS3L @ F9C
2x 2GB Corsair Dominator DDR2 1066Mhz [5-5-5-15 2T] 2.1v {400x2.66D}
4,25TB Storage
Powercolor ATI HD4850 PCS+ 1GB DDR3 700/1960
PSU Corsair 450VX
Case Elegance [3x 80mm + 3x 92mm + 3x 120mm]

Stable configuration at 3.6GHz w/ the new Corsair Dominator and in bold is my first attempt to increase my over with no sucess.

I'm using Windows Vista SP2 Ultimate x86

Infos w/ Everest Ultimate Edition 5.01

Temperatures w/ over at 3.6GHz:



Infos w/ CPUZ:



O Core Voltage keeps changing from 1.232 to 1.248 this is normal? cus i don't remember...



Some screens from the bios:








Thank you all for the help!

followed your method as decribed with e8400 3.0ghz core duo cpu
gigabyte ga-ep43-ds3r/ds3 motherboard
4 gig ocz reaper pc8500/1066 oc memory
and has clocked to 3600.2 mhz
system 38c cpu 26c @ idle with stock cooler
thanks to all for the info and what a fantastic site this is

ok not that its a bad thing but you have the CO stepping(i do also) 3.6ghz is the sweet spot for that chip, yes it can go higher but will take some work at getting it there. from what i see in your settings the first thing you might want to do is change your mem multiplier from 2.66d to 2.00d. yes it will under clock your mem but it will also help you get the CPU stable first then you can tweak your mem once it is stable.
second thing. i just learned this myself trying to OC my Q9550 on my GA-EP45-DS3R mobo. in bios in MIT to the right click on enable optimized default settings. this makes a big difference. then go back to the top of MIT and set your ROBUST GRAPHIC BOOSTER to "FAST" setting the optimized default make pre adjustments to the mobo that isnt normally done when not OCing. take a look at this link here. it is where i was shown about the optimized default settings.

id say do those things first and see what you can do with it. id say you will be pleased. hope this helps some.
