In my first attempt to overclock this x58 ud3r combo upon first restart the my computer just kept turning on and shuting off repetitively. I couldn't even get back to the bios and had to reset the CMOS which got me back to square one. After reapplying my previous stable settings which was basically all stock with my memory timings set to their specs it's fine now. All I did, and this wasn't even aggressive, is to change my qpi to 32x, my uncore mulitplier to its lowest frequency, changed my ram back to 1066 which is going from 2x12 to 2:8. I kept my DRAM voltage at 1.5 which is what my ram is rated for and never touched the vCORE which was stock @ ~1.3 and my other voltages were not touched. I disabled turbo boost and as a first step increased the BSCLK by only 10mhz from 133 to 144 and upon reboot is where it just kept on cycling on to off.

I'm not sure what my next approach should be and was wondering if anybody had any ideas with experience or who is familiar with this board in overclocking it? Any help would be great. Thanks.
