here is my setup

e6600
evga 680i a1
bfg 650w psu
g. skill 2x1gb 6400
tuniq 120
antec 900 case
bfg 7950 gtoc
voltages: cpu:v1.50 ram:v2.225
at first i had something caled vdroop where the cpu voltage wouldn't stay the same, but it went away when i lower my voltages a lil.
i was hoping to be stable at 3.6ghz but nowhere near stable, orthos gives me a fatal error or restars my pc. when not testing stablility everything seems fine, playing games, watching movies, conveting movies. with the tuniq my temps are exremely low(FYI incase anyone was deciding whether to get the tuniq or not, its excellent temps dropped atleast 17°,after lapping the cpu and tuniq).um so far all i've done is set the fsb 1600 bump the volt. to 1.5 and set my ram 400mhz at 2.225. i am aiming for 3.6ghz stable with ram at 1:1 ratio. i'm not quite sure if i should have messed with the other voltages.
pls no one bag on me if i made a mistake somewhere, its my first OC attempt. any help or opinions is appreciated.

oh yeh i dont kno what load and under load means but. when i power on my pc its at 21°, and at 41° when i'm playing a game or converting movies when it set to 3.6

Losen up a little the memory latences. You didn`t mention what is the northbridge voltage.

Ok.First you need to make sure that coolnquiet is disabled in your bios.Leaving this active will cause instability and make your system crash.Next you have to make sure your v-core voltage is right.The more you push the fsb the higher you need to put the cpu voltage.If your voltage is 1.33 at stock 2.2ghz,then at 2.5ghz,your voltage should be around 1.4-1.45 to maintain stability.Now some will say to drop the multiplier on your hyper transport from 5x to 4x.With some boards this is a necessary piece of the puzzle for stability.But I also know from personal experience that it is not always necessary.In fact I ran my X2 4400+(toledo core)at 2.7ghz stable on 1.55volts for more than 3months with no hassles,on my EVGA nf4 MB.Anyways,hope it helps you some.Goodluck.The last piece of the puzzle is adequit cooling.Without good cooling you'll find your machine crashing and freezing.

If your CPU volts are 1.5, then that is more than sufficient. I've gotten many e6600's to 3.6 on less voltage than that. I would say this instability is the result of some bios settings that affect either the NB or memory. Loosen you RAM timings. Raise your MCH voltage by at least .1V. Disable all the NB functions, EIST etc. Finally, it is possible you just got a not-so-hot E66 and you need to back down the overclock a little bit. I doubt that, but it is possible. Good luck, keep tweakin.

bobbys, That is one nice setup you have their. I have an EVGA T1 board and I love it. So far I have hit 3.7Ghz with my set up. Also what is the batch code of your chip. Depending on what week it is also has alot to do with its overclocking abilities. Here is a link that I used that helped me a bunch with my overclocking. Also instead of a 1:1 ratio make sure you choose linked & synced in your bios. It is also a 1:1 but for some reason this board likes the Linked & Synced setting.

this is the error orthos gives me, setting my ram to 5-5-5-15 but no luck.
