here is my setup.

asus p5w64 ws pro mother bord
Intel e6600
2 gig crucial ballistic
700 wat p/s
armor LCS water cooled case

if i leave the settings stock i have no problems. once i over clock the CPU to 3 ghz if i reboot the machine it will start and then power down and continuously restart and never boot. i have to let it restart and then shut it off just as it restarts to get it to boot again. when it does start up it says that the over clock failed and i go in to the bios setup and just save the settings and it boots fine. the machine is stable and runs at 47c under full load. i have it set at MHz front side at 1.35 Core volts and 2.2 volts for mem which is stock for my memory. i am going to call asus and ask them about this but i am sure the will just blow me off and say that they will not support anything over the stock speeds. so i look to the people of this forum for help. thanks to all that can give me help with this.
 
A reboot-loop without posting could be almost anything--low voltage, incorrect RAM timings, bad PSU...

My DS3 reboots like that when it doesn't like my OC settings, eventually returning to default settings. I would try upping your core voltage. You never told us what your FSB was, either.
 
fsb is 1333. i have set the core as high as 1.4 volts and it still has the same problem. i will try setting the timings a bit higher but the factory ones are 4-4-4-12 and that is what i have them at. the memory is at MHz/832 and i have pushed it to 1000 with no problems with the same timings. i have all the other setting set at stock so i don't know if i should raise the voltage on fsb, mch or ich. if anyone has a setup that works with this board i would like to see there settings. i really think this board has a problem and needs to be sent back. i have tried to re flash to a older BIOS but asus has made it so none of the programs that come with the board will allow this.
 
just got off the phone with asus. the guy i talked to was very nice and knowledgeable but he really could not help. he said if it runs at stock speeds there is nothing he can do. its sad that a $50 asrock mb overclocked better then this board. well not really. i can over clock much higher with this board it just wont reboot. oh and all you that reset the board by the jumper might like to know if you turn on the power and as soon as the power light come on hold down the power button till it shuts of it will start up next time. it might only be my problem that can be solved this way but give it a try. i can not find a way to flash to a older bios to see if this will fix the problem. i have tried the BIOS flash utility both in dos, windows, and the bios and they all say that the version is older then the one that is in the mb and will not allow me to flash to a older version. anyone know how i can flash to a older version? thanks.
 
just bumping this. i really need some help. if anyone has this MB and has there C2D overclocked pls chime in. i could really use some help on this problem. i can overclock the hell out of this CPU and run it stable but i need to find out how to stop this problem of the system shutting off when i do a windows restart and power cycling on its own. anyone know what the max safe setings are for the voltage on the chipset? ich and all the other setings in the bios? i did shut of hyperpath 3 as i have seen ppl have problems going over 300 on the fsb with that on. thanks. any help would be great.
 
Sounds like the same problem a lot of P965 boards have. One solution to that is a) give the chipset more voltage, some people go as high as +0.3v without problems and b) set the RAM timings manually as well as the RAM voltage.
