HELP OC'ing I5 3570K on Gigabyte UD4H

I am new to OC'ing. This is my first OC ever.

System:

Gigabyte Z77 UD4H
I5 3570K
G.SKILL Ripjaws X Series 8GB (2 x 4GB) DDR3 SDRAM DDR3 1600
OCZ 700 W psu
EVGA GTX 670 FTW 4GB
SAMSUNG 840 Pro Series 256GB SSD
Cooler Master Hyper 212 EVO
+ 3 Case fans. (not sure the sizes, maybe 2x120mm and 1x180mm)

Question is.. I went into the bios and set the multiplier to 45 and left the voltage settings to auto.

I am using easytune6 software to monitor voltage and temps, prime95 for stress test. I have been stress testing for almost an hour and my temp is between 65c and 70c, Voltage at 1.248 may have went almost to 1.3v at the first but pretty much staying at 1.248v now.

beside of my cpu voltage it shows voltage for ddr a/b voltage @ 1.536v (idk if this is good or not) on the easytune6 software.
I also have the task manager open and its showing speeds of 5.90 to 5.94 GHZ at 100% loads.

Does everything sound ok? from what I've read it seems ok.. but I'm no expert. any info would be appreciated

Sorry, unless you are cooling with liquid nitrogen, there is no way you can get that fast. Something is up.

I don't know what that task manager on the left is telling you, but on the quick summary on the right you have your answer.

Note that your Bclock is 100.32MHz, that's right.

Note your multiplier is 45.

So the CPU is running at 45 X 100.32MHz or 4.5144GHz

That's a great boost. Those Cooler Master 212 EVO's are the best cooling per dollar. How does it sound? Is the fan maxed out?

i can hear it a little.. the gtx 670 fan gets a little loud after a hour or so of gaming... I wasn't sure about the task manager either.. if i'm just streaming a video it shows around 4.0 to 4.6 but when I was running that prime95 it would say 5.90 and 5.94. I ended up setting it back to stock speeds until someone said if there was anything wrong or if it was all good... the windows 8 rating went from 7.9 w/ stock cpu to 8.1 with the boost.

You're set with the CPU overclocking. I hear that auto voltage usually sets the voltage too high. You may want to lower the voltage a bit keeping the overclock the same and see if you can get away with it. Your CPU will last longer and you save power.

I see that you bought a 670 with a reference cooler. Yeah, they tend to run a bit noisier. Maybe next time you can get one with a custom cooler like you have on Gigabyte or MSI.

I might try to lower the voltage then.. when I set it back to stock speeds i get .780v to .876v average when its pretty much idle. when I stress test at stock speeds I get 1.068v. So I guess that would be a good starting point.

here is a 4.2ghz oc... I changed the voltage a little .. 1.068v under full load with prime95.. idle at 0.756v to 0.976v

task manager was still showing higher speeds though (about 5.14 to 5.17 ghz)under full load..

when I oc in the bios i am changing each core to 42... I can do a screen shot of it if u think it might help to see whats going on
