OCed RAM, Did I Do it Wrong?

A couple of weeks ago, I found the BIOS settings to push my Kingston RAM to the fastest, 533 MgHz. or 1066, speed. This was just pushing up the RAM voltage to 2.2 volts and adjusting the ratio setting. And I ran the system for some two hours and then had BSoDs. So, I set everything back to default and everything ran fine. Several days ago, I again, tried the RAM overclocking and the system ran 15 to 45 minutes and went through a single BSoD and recovered to repeat the process. Following the system overclocking guide from this forum, I adjusted CPU, MCH, VTT voltage to stop the BSoDs, at times it appeared, I extended the time between the BSoD happening, but didn't stop them. Then I had problems, that appear to be from file corruption and the system, OS, are pretty much bombed. In hindsight and the struggling experience from a NVidia 680i and 780i MBs, I think one or more of the memory modules,failed in the first try and the BSoDs were the result of. It appears moving back to the stock performance is fine. I tested the modules in a single DIMM and double DIMM mode for over 30 minutes, no overclocking, until my system fell apart. Did I do this process wrong or was it a failure of the RAM to tolerate overclocking?
 
Is the ram rated at 2.2 V ? ( I looked it up and it is- OK) but thats pretty high and more is not better with some ram. Do the test below at 2.1V and see if it will pass and if not then go to 2.2V.

...

Clear Cmos/Bios load factory defaults, go in and adjust whatever basic settings are needed, set it up to run stock making sure the memory is set (mulitplier) to run at 1066 with as much stuff on auto as practical and test your memory using memtest86+. Download the zipped .iso and burn a CD. Boot from the resulting CD and let it run 2 or more full passes.

...

The 4x1 GB might be some issue but the newer boards are not as "touchy" as older ones and I would think it should do stock timings and speed without an issue.

What I would like to know is a complete run down of all your OCing settings and voltages. Then we could offer constructive help.
 
In my first attempt, I disabled pretty much everything, MSI's D.O.T. and Intel EIST and just pushed the DRAM voltage, per Kingston to 2.2 volts. My second go round, I pushed CPU voltage to 1.34 volts and the MCH, Nothbridge, to 2.20 and a couple steps above, but it seemed 2.20 was the best setting. I adjusted the VTT and the Southbridge, but don't recall specifics. I never got to a Red setting in the adjustments or near, as I recall. I expect selecting those, put you at the point of damaging the board or components, RAM, CPU. I was so surprised and impressed with the board on the first go round, that I overclocked the RAM with such ease. I have the FSB jumper settings at max for 400 MgHz. and the system is pushing the CPU to 9X400, 3.6 GHz. all the time, as well as, doing this during my RAM adjustments. I have Spread Spectrum disabled all the time. On the first attempt I ran around two hours had a BSoD and booted to two more, and then went back to stock settings. Temps,reported by Core Temp were 107 to 109 F Running stock settings brings it down to 103 F. I used RAM settings of 5-5-5-16 to 5-5-5-18, during the first attempt the 5-5-5-18 were used at Auto setting, per CPUz.
 
I suggest you take a more methodical approach. Go slow, take notes, test between changing settings. It should like you should be able to get to 3.6 or near but finding the limit where issues like freezes and BSODs do not occur should be your goal. In general you set your ram to run stock or slower while slowly increaseing CPU FSB and testing. After determining where the cpu tops out you then go back and look at the memory system. Many guides on the net and stickly here.
 
My OC of the RAM was my attempt to just achieve the max SPD or performance profile of the Kingston HyperX. I am not looking to push the CPU to 4.0 GHz. and the RAM beyond the 533 Mghz. These specs are thrown down on the table by the RAM manufacturers and they make it seem this should be readily attained, pretty much like a stock setting. Add the OC adjustments of the MBs for accomplishing this, I, as a newbie, would think this is not a major OC project. But it appears there is market hype and the reality, which are two very different stories. When I did just push the RAM voltage to 2.2 volts in the BIOS Cell section it did report the RAM speed as 1066 being available in a grayed out area. I wonder if the MSI D.O.T. function would have recognized this and handled its OC duties accordingly?
