Can't Overclock!

I am having one hell of a time trying to overclock this system. I have never been able to boot into Windows 7 at anything higher then 3.5ghz with all Auto voltages. Everytime I try pushing it further with the voltage/FSB...the board starts to act very weirdly.

The normal procedure for this board to reset the CMOS due to a bad overclocking is as follows. I can hear my 5670 fan rev up like its going to POST. Wait 30 seconds, and this repeats 2 more times. The system will then finally POST @ stock settings. What usually happens, is the system will power on and just sit there, never attempting to reset the CMOS, or will do it once or twice. I'll power off/on, and this will repeat 5-8 times. Once it's done doing that, it will POST @ my OC and try to boot into Windows. Instead, I'm greeted with the dreaded blinking underscore. I'll reboot 3-4 more times, and this will stop happening. Instead, it will POST @ my OC and say "WAIT..." I "waited" for 30 minutes, nothing. Turn the system back on/off, 2-3 more "WAIT..." later and the CMOS will finally reset.

I've read a few things about the 4 phase power control on this board not being able to handle the 1055T very well, or any 6 core CPU for that matter. Also heard that I should be upping the VDD and not the CPUv?

Funny story: During one of my 4ghz attempts, I peered into my opened case side, and saw an amber light. The board does NOT have any amber lights, unless its a transistor on fire. I then panic and spray dust off at it, the propellant fuels the fire and 2-3 more transistors light a blaze surrounding my 5670. Yanked the PSU cord and it eventually fizzled out.

Don't you hate it when that happens! That board obviously had some issues... maybe a bad MOSFET or voltage regulator?
 
yes i would agree that board had a fault in it.. yes the msi boards do have issues with the 4 phase power mostly because they are using cheap ass mosfets that cant handle the power needed for the x6's..


honestly thats not the procedure to reset the cmos.. thats called being lazy and hoping the motherboard clears it for you.. its quite simple to clear the cmos.. takes a whole 45 seconds.. unplug the psu from the wall.. pull the cmos battery for 30-45 seconds.. put the cmos battery back in and plug the psu in.. boom cmos is reset..

as far as acting weird and auto voltages.. well theres your problem right there.. you should not be using auto voltages.. you should be manually setting them.. cpu voltage should always be set no matter what.. never trust a bios to set the voltage correctly because it never will.. as far as the overclocking goes are you dropping the multiplier on the ram as you increase the FSB(HT)?

btw i really hope HWmon is wrong on that +12v 13.9v holy crap.. my 550HX never went over 12.25v on any monitoring program..

Google what are reasonable voltages and set them manually. When your clocks get high the board wont be able to guess how to set the voltages.

I may have been adjusting the wrong things when overclocking, I've never overclocked with an AMD system, just Intel. What should I be manually setting for the overclock to raise the CPU voltage?
