I bet it's your ram. FSX is prolly the only program you run thats eats up so much ram. Your ram prolly isint stable at those higher speeds. Run Memtest or Orthos with ram checking

goto control panel -> system ->advanced tab -> startup and recovery button.  uncheck the 'automatically restart' button. This will stop the computer from automatically restarting during a crash. But be careful!!  If you leave it on this blue error screen too long it could start burning up your hardware. If you are away from your computer and it crashes... come back later.. be prepared to find a dead computer. So after you've troublshooted it make sure to turn it back off.

You probably need to up the voltages to your ram. Should fix your problem.
Some ram just can't handle it though. Good quality memory can make a world of difference. I suggest corsair xms.. it's made for overclocking and is the most stable stuff that I've ever used.

A powersupply that isn't strong enough can cause this problem as well.

Also, be careful.. it sounds like your temperature sensor on your cpu might not be functioning properly. (this is quite common) check temps right when the computer is turned on after being off for a long time.. then check it again under full load to see how much it has moved. If not much.. it probably doesn't even work.

You should probably create another threat for this but oh well... to clock your cpu you can increase the processor bus. That will also increase the memory speed so you'll probably have to slow the RAM speed down a little bit. The trick is finding the sweet spot: good cpu clock and good memory clock... and good FSB : DRAM ratio.

I don't think its your overclock check your PSU because it can go on and off.
