Core Voltage too high for i3770K

I just built a new RIG with following SPECS ( be advised nothing is Overclocked )

INTEL 3770K (w/ Intel Stock Cooler)
MSI Z77 MPOWER (Bios v17.5)
MSI GeForce 680 LTNG

After installing Windows 8 and running PRIME 95(30min) I realized the Core Voltage reported in CPU-Z is v 1.240 and Temperature reach to 87c quick under load . I am worried as to why my Core Voltage under full load ( 3.9 GHz ) is 1.240. I thought these 3rd Generation chips use less voltage then my old 3930K.

Is 1.240 Core Voltage normal under load for these chips or did I just got a bad chip? I haven't even tried to overclock it yet. While the system is idle the Core Voltage seem to be fixed at 1.096 which is still high.

I almost feel like it might have been a bad idea selling my Intel 3930K with Asus sabertooth x79 I used to have.

That's higher than average, but it's not terribly unusual. It could just have a very conservative VID and still be able to overclock just fine. I'd get an aftermarket cooler before I tried overclocking it though.
 
If the cpu Vcore is set on "Auto" that is most likely the reason it is using such a high voltage..My cpu only takes 1.272V to reach 4.8Ghz Prime stable, so that is right in the area you are running..

I will say this, get used to the high temps unless you want to de-lid the cpu like most of us that want high overclocks without a throttling chip have done..Why on Earth would you have gotten rid of a 3930K and excellent MB to jump to a Z77 setup? I wish I had known, I would have traded you mine:p!
 
After playing with new MSI MPOWER and 3770k I figured it was a bad idea to get rid of my old i3930K and Sabertooth. These new IVY Bridge 3770K chips runs very hot even with slight overclock. At stock speed these chips are great with power efficiency and temperature, but these aren't designed for OC at all. 3930K was a great chip and sabertooth X79 was awesome board. Intel did a terrible job designing 3rd Gen i7 Chips. Lets see what IV-E has to offer. Performance wise i3930 was easily OC'd to 4.8 GHz and had great benchmark scores.

It's higher than average. At 1.24 I was able to run a 44x multi.
 
okay I was able to set the Voltage to MANUAL at 1.050v . During PRIME95 test no crashes were observed at 1.050v voltage which is great, but Mainboard refuse to put CPU in idle state when I switch the settings from AUTO to manual. All the power saving features go out the window with manual.

Any Ideas ? I heard some issues with MPOWER Z77 mainboard.
 
While all processors are different I havent heard of an Intel® Core™ i5-3570K or Intel Core i7-3770K that is only hitting 3.9GHz at 1.25v. I was able to hit 4.6GHz with my Intel Core i5-3570K and was sitting at 1.25v but I didn't like the temperatures. So I would check to see if I could test the processor on another board. May a local shop will have a test board you can test it on.
 
Something doesn't seem right with that. Have you cleared the CMOS and reseated the CPU and HSF yet? Have the latest BIOS release?


After the CMOS clear, only set date and time and rerun the test.
 
I am running my 3570k at 4.8, 1.3v in the bios and max temps I saw was 82. Still well below the 105 max.
