My i5 with Cooler Master 212+ on it is at 1.240 volts at STOCK speeds, everything in the BIOS is set to AUTO. Is this NORMAL?

ALSO, whenever I overclock to 4.5 GHz and i set VCORE to 1.250 or even 1.280 i get BSOD. I set it to AUTO and it boots perfectly but after boot when i check the VCORE it says 1.400.



CPU: i5 2500K
Mobo: Asus P67 Sabertooth
RAM: 2x4 GB G.Skill Sniper 1600 MHz 1.5 V
GPUs: Asus GTX 560 1 GB
Evga GeForce 9600 512 MB
PSU: Antec EarthWatts 750w
 
Solution
When you set your BIOS to auto settings it will tend to send more voltage than it really needs. 1.4 Vcore is extremely high for an overclock of 4.5ghz (as a reference, I was able to oc my i5 to 4.6ghz using approximately 1.320 Vcore. I would suggest working up in 1-2 increments from 1.280 until you don't get a BSOD. Afterwards, stress test your new overclock with a cpu stress testing program (I use prime95) overnight to test your cpu's stability under load.

Btw, I have a similar setup, I am also rocking a Coolermaster 212 in push/pull...so you should get decent temps even at 4.6-4.7.

Good luck!

Edit: Forgot to ask, what are your other settings in BIOS? Are they all default as well?
Alright, thanks to both of you. I will start Overclocking but first I think I am going to remove my CM 212+ see what I did wrong and re-paste it and set it back up again. Really helped with everything, thanks!

best of luck on your oc, if you can keep us updated on how it goes!

edit: if you have to room in your case, a very cheap upgrade is to get a second fan for your CM and use a push/pull system. this should knock your temps down several degrees
