I have overclocked my 4670k on msi z87 g45 mobo and currently running under following settings

CPU Ratio: 44x
Ring Ratio: 35x
VCCIN Voltage (CPU Input Voltage): 1.9v
CPU Core Voltage: 1.32v
CPU Ring Voltage: 1.2v
CPU Ratio Mode set : Fixed
cpu core voltage mode : override
ring voltage mode : override

Though i set the modes to override,when im stress testing the cpu in AIDA64 i can see the voltages going over 1.3v(1.36 max)..im aware that this voltage is too high for the CPU but i cannot maintain a stable overclock while the cpu core votage is below 1.3v..(1.2-1.29 etc.)..does this mean i cannot O/c this cpu to 4.4 GHz?or what can i do to make this overclock stable whie keeping the voltages below 1.3v

When you set a voltage through the BIOS it is not 100% guaranteed that's what you'll get. Usually you should expect ~0.02-0.04 difference between the voltage you want and the actual voltage. So when you set it to 1.32, you are actually setting it to 1.36. And if you set it to say 1.26 you are actually setting it to 1.3. These voltages are a bit high (also depending on your temps), and in a 24/7 use are not recommended. Try going for a more mild overclock, and lowering your voltages, your CPU will thank you for it!
