So i have a i5-7600k and at stock it says 3.8 ghz, yet in task manager it says im running it at 4.14 ghz even though i havent oced or anything, if i overclocked to 4.6ghz would that mean it would be overclocked by .8 ghz or .4 ghz, because if its .8ghz i dont want to burn out my cpu in a few months, and when i actually do overclock, what values and settings do i have change? Does it have to be in bios or can it be in the Intel Extreme Tuning thing?

The task manager is probably looking at your turbo speed. The base is 3.8, but it will turbo higher for certain task.

If you bump your clock up to 4.6ghz it would be an increase by .8ghz. But high clocks do not fry a CPU. What fries CPUs are high temps and high voltage. How clocks come in to play is for high clocks, you have to increase the voltage. When you increase the voltage, you increase the temps.

With that being said, you should not have any temp issues running that chip at 4.6 with reasonable cooler. You may be able to hit 4.6 on stock voltage, which would be a free performance increase.

I like my average temps under load to be under 80C and I like to keep my voltage below 1.35. If I were you I would go to the bios and...

I like my average temps under load to be under 80C and I like to keep my voltage below 1.35. If I were you I would go to the bios and just change the frequency multiplier to 46 and boot your PC. Run a bench and see if the system crashes. Watch your temps during the bench. You want the average temps to be below 80C. It may spike above 80C, that is fine for me as long as the average stays below 80C. If the system crashes you have two options, one is to lower the frequency multiplier to 45, they other is to increase the v-core volts. Increasing the volts increases heat which can shorten the lifespan of the CPU. But if you keep your average load temps below 80C then the CPU will become obsolete before it reaches the end of it's lifespan.

Cinebench is a very popular CPU benchmark.

I also recommend Intel Extreme Utility (XTU). Intel designed it for use on their chips. It also provides a stress test and you can easily monitor temps all on one screen.

80c for the internal temp or package temps? The only settings i have to touch are frequency multiplier and (maybe) volts? And should i do anything with the xtreme memory profiles or uncore freqencys? What should i set the volts to if it doesnt crash? Im not planning to go above 4.6

80C for package temps. If it spikes above 80, its fine, you want to look at averages. You dont want the chip to run at high temps for extended periods of time. Anything below 90C is considered "safe". So I am a bit conservative when I go with 80.

Yes, for a simple OC of 4.6, all you will have to change is the frequency and the v-core. All the motherboard bios are different, I suggest you google the name of your motherboard and OC and watch some videos. Jayztwocents has some very good videos that have good content. This is one on how to overclock, it will teach you enough to get to 4.6.

Yes, want to run XMP (extreme memory profile). XMP is just a one button click OC of your memory. It is literally one button and your memory will be OCed. But dont expect much, as Intel CPUs run great at base memory frequency.

The uncore is for the cache ratio. You dont need to OC the cache ratio for a 4.6 OC. Just leave everything else alone except for the frequency multipler, v-core, and XMP. Dont worry about crashes or messing up. Even if your chip gets to hot, it will shut itself down to prevent damage. They make them pretty hard to screw up. If you crash, restart. If windows does not load, go to bios and restore to default settings (removes all changes). If it gets in a loop and you cant get into the bios, clear the CMOS. Pending on your mobo, there may be a button to clear CMOS. If no button you will have to clear the jumper or remove the battery on your motherboard for a couple of minutes.

If it does not crash at 4.6, you can undervolt the chip (v-core), but I would just leave the voltage at stock settings.
