Last night i did my first attempt at overclocking my cpu. It's an i7-2600k, i got it to 4.4ghz by just increasing multiplier 1 at a time then running prime for 15mins each time until i got to 4.5 where prime caused a BSOD. At this point i tried increasing the vcore, however where it was normally set to 1.255 after the BSOD it had been auto changed to 1.37 which i thought was to high so i put it back to stock then slowly increased it to try and boot into windows, however i couldn't get passed the windows loading screen (i got the vcore back up to 1.3 before stopping) at this point i set the vcore back to stock and multiplier to 4.4 then ran prime all night. It appears stable at this settings but I'd like to go higher, i've read guides that say to change a bunch of settings in the bios for overclocking, and then seen other people saying that you should only need to do voltage and multiplier. Is there something i need to enable/disable to push past 4.4? or did i just not put the voltage high enough? I should also note that the highest peak temp was 67 degrees Celsius when i ran prime over night, the shorter prime runs peaked at about 64, idle was 35~40 across the cores.

Also after i started overclocking i also started getting a usb overvolt warning, not sure what's causing this or how to fix it.

What are you using your computer for?
4.4GHz not enough?
Another 0.1GHz is going to make a huge difference? No.
USB overvolt warning. Sounds like you've been messing where you shouldn't have.
I'd suggest not taking your voltage up so high (I personally don't feel comfortable above 1.31)

The guides that you're reading, you need to make sure you're doing exactly as they say, especially if you don't know what you're doing.
Disable what it tells you to, enable what it tells you to. Unless you know for a fact differently.
It'd really suck to fry that cpu! :( 
This is a good place to start, here

With that mobo and the 2600K, you should be able to go far higher.

At this point it's all about e-peen. Machine is primarily gaming rig which i code on as well though my compile times are fast enough that I'm not concerned about making it quicker for that purpose. The thing is with the overvolt warning I haven't touched anything, being a newby at it i literally have only touched the multiplier and vcore for fear of the unknown. I read through that guide before but i might just go back through and do some googling of each of the bios options it want's me to enable/disable so i understand what's going on.

The voltage is the thing that scares me, it's why i set my goal for 4.5ghz instead of trying to push 5ghz (probably would be hard with air cooling anyways) keeping it close to stock voltage makes me feel more comfortable about the whole deal and i know that the voltage is the main reason at higher overclocks you get alot higher temps.

Your right that .1ghz wont make much of a difference so if i can't get there it's not a problem, I just wanted to hit the target I set and i know my rig should be capable of it.

Most of the time you should be able to just bump your volts to get it to post. I would set your bios to default setting then start over with your overclocking and see if that fixed the usb overvolt warning. You might have better luck with lowering your multi a notch then increase your chips ratio. Good luck
