Safe cpu voltages?

[Madluri]

Hi I got my i7 4770k overclocked for 4.6 ghz with 2.275 volts. I have been surfing the web, and some people say that anything above 1.225 volts is dangerous. I dont think cooling is an issue because im getting 37 degrees Celsius at idle with my corsair h100i. I just wanted to know If anything above 1.225 volts is dangerous.

what are load temps? Idle doesn't mean anything when overclocking.

2.275 volts? Are you sure thats your vcore voltage? That is insanely high for any CPU and it should definitely not be getting any sort of reasonable temps

Ill get back to you with that im stress testing

Im sorry i mean 1.275

I'm sure he meant 1.275v, if it were at 2.275 it's not the temps of his CPU he'd have to worry about, it would be the rest of his house catching on fire.

1.275 is actually very good for 4.6 and is perfectly safe. I try and stay under 1.3v but the chips themselves are supposed to be good all the way up to 1.5v. Anything past 1.35v I've heard is where you start seeing the life of your CPU shorten by quite a bit.

Ok thanks

Here is some stuff from the Intel Temperature Guide which talks about vcore.

 

 

Overclocking and Vcore

Power dissipation can reach 130% to 150% of your processor's TDP envelope (Thermal Design Power) when Overclocked with either Auto or Manual Vcore settings, so high-end cooling solutions are required. Regardless, excessive Vcore and temperatures will result in accelerated "Electromigration", which prematurely erodes the Traces and Junctions within the processor's layers and nano-circuits. This will in turn eventually result in Blue-Screen crashes, which will become increasingly frequent over time. Therefore, Vcore settings should not exceed the following:

45 Nanometer 1st Generation Core i ..... 1.40 Vcore
32 Nanometer 2nd Generation Core i .... 1.35 Vcore
22 Nanometer 3rd Generation Core i ..... 1.30 Vcore
22 Nanometer 4th Generation Core i ..... 1.30 Vcore

3rd and 4th Generation Core i processors use a poor quality, unevenly spread Thermal Compound between the top of the Cores and the underside of the Integrated Heat Spreader (IHS). Consequently, some processors show a wide variation between Core temperatures, or one Core which runs significantly hotter than it's neighbors.

This has prompted some enthusiasts to "de-lid" or remove their processor's IHS to replace Intel's Thermal Compound with a high quality Thermal Compound. However, 2nd Generation Core i and earlier processors don't suffer from these problems, as Intel used fluxless solder, which provides efficient heat transfer.

so atm your right is you are 1.275.
