When I go to BiOS and push the 'OC' button to overclock the computer just goes black immediately and turns off. Is this a power supply issue probably? If so is there a particular power supply voltage that will take me to 4+GhZ?

 

I don't know if anyone can explain why there is no multiplier setting to easily OC to say 4.2 and stepwise up?

 

Lastly I plan on buying a GT 660Ti card is this overkill?

 

Thanks so much

The auto-overclock routines will generally reboot the computer several times so they can set and test various clock speeds, so turning itself off is part of the process but it should turn itself on shortly afterwards.

 

What motherboard are you using?

 

A GTX660Ti isn't overkill for FSX in fact most people will recommend a GTX680 with a GTX670 being viewed as the best price/performance compromise.

It didn't seem like it was about to do that. It went black and I turned it back on. Maybe I will try waiting. But there was no warning that it would reboot; it happened literally the moment I pushed enter.

 

My motherboard is an ASUS P8Z77-V LX.

Like PieEater said, some boards will cycle looking for a bootable config. Your motherboard does that cycling. Like suggested, try letting it cycle and if it doesn't after a minute or so, then make sure your memory settings are correct.

Actually I found this on Tom's Hardware:

 

This hasn't been talked about a lot, but every overclocker has to appreciate the fact that Intel allows Ivy Bridge-based K-series parts to change their multipliers during operation. It's no longer necessary to reboot between modifications. We've been doing this with our AMD chips for a while now, so kudos to Intel for catching up. Using Intel’s Extreme Tuning Utility, a well-designed utility, we're able to tune our Core i7-3770K from within Windows.

 

 

Will have a look at that. 

 

Sorry what do you mean by "memory settings are correct"? I'm a newbie
