EX58-UD3R keeps rebooting

[Tribesone]

Hello I've recently purchased these items:

EX58-UD3R - http://www.newegg.com/Product/Product.aspx?Item=N82E16813128375]

OCZ platinum 6 gigs DDR3 1600 - http://www.newegg.com/Product/Product.aspx?Item=N82E16820227381&Tpk=OCZ platinum]

i7 920 CPU

Corsair 650 TX - http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005]

Nvidia 260


The problem I am having is that upon starting up the system, within about 1 minute it will always turn itself off. According to the gigabyte manual going into the bios and setting "Load fail-safe defaults" should help, but this didn't do anything for me.

One that I noticed was that the voltage for the DD3 in the bios is set to 1.5v, while the OCZ ram sticks have a 1.65v label on them, would this be a problem? Unfortunately I cannot see any way to change the value from within the bios, as the method mentioned in the manual simple doesn't exist in the version I see(something called Extreme Memory Profile).

I've also gotten the following message when entering the bios menu(Was after I lowered the multiplier and increased the timings on the DD3 to see if it would help):

"The system has experienced boot failure because of overclocking or changes in voltage."

Of course I was actually underclocking ... and everything else is on default settings..

Anyone have any suggestions? I'm pretty lost..

Thanks

Check the CPU temps in the BIOS.

Sorry I don't have an answer, but could you help me with something? I tested a UD3R and found that Vista Sleep mode doesn't work if Bclk is above 195. Can you test this and let me know if SM works at high Bclk on your board? Rumor is that SM has been fixed with a bios update. Also, hyperthreading must be disabled. Thanks.

Sounds like a classic thermal shutdown; pull the MOBO and check to see that all four retaining pins on your fan/heatsink are properly seated and locked - 90% of the time with this problem, oops - one isn't fully seated... Best way to get 'em in properly is to lock diagonals first, then do the other two. IMHO, this is the best benefit of GB's 'ultra durable' design - these MOBO's will take the pressure to get the pins locked properly without giving you the sinking feeling that you're a half pound of pressure away from a sickening 'crack' noise!
