Overclocking i7 6700K help

[Ayousry]

Hi guys ,

Am very new to overclocking , and after watching a utube video i did the following:

Open Gigabyte bios menu
Changed CPU freq ratio from auto to 44=4.4ghz

Changed vcore From auto to 1.275

Now i dont know how to do a stress test but i did stressed cpu via cpuz
For 1 min then ran a very demanding flightsim to check volts and temps

I got it bet 1.200 to 1.29v
And temp 50-65c

Is it safe to keep these settings ?

Secondly i tried 4.5ghz and win10
Started normally and even temp and volts was fine but when i started the same flightsim win10 crashed!!!

Why did it crash when i hv stable volts and temps?!

Thanks

The new i7 when overclocked doesn't increase gaming performance much:

But this is a good guide to follow to learn with:

Remember overclocking is more about the process and procedure of arriving at your final overclock, than it is about hard and fast numbers that you enter.

Because it was not stable.
You fixed the voltage, and the temp could be good but when you changed the cpu core from 4.4 to 4.5 you reached a somewhat unstable status, probably on high cpu loads you will crash.

Test the cpu stability not with a game but with a proper test, CPUz or whatever, as games usually are more stressfull for the GPU than for the CPU.

Go back to 4.4 and run CPUz for a period of time, 10 min for example for stability and temperatures and if its stable then go to 4.5 with a slightly more value on vCore.

For the vCore you are almost on stock values, the max i would use is low-mids 1.3s, close to 1.4 probably you will shorter the CPU lifespan.

before and after the cpuz stress test VCORE was bet 1.248-1.26 max and temp 30-34 max

I ran the test for 15mins ,VCORE stayed at 1.200v all the time ,didn't change at all
and temp was bet 50-65max also VID was bet 1.26-1.34v

am not planning to overclock more than that ,doesn't worth the risk and time.

now, am I considered stable at these readings ?

is only the VCORE and TEMP is what matters and should keep an eye on them?

They are very conservative (65º at max and 1.2 give you still room for more overclocking) but they are good and if they are your first overclocking i think is worth to stay on the safe side.

Mainly yes, the only think you could look into (and is worth it) is the memory. If not using a Xmp profile or changed the default values probably you are running the memory at stock values (and lower than the potential maximun speed for the RAM).

You could look into more parameters of the bios and tweaking for more extreme overclock, but as i said before i think is nto worth it.

On the temps take a look into the Tcore and Tcase because they are not exactly the same values but if the max for the burning test is 65º i would bet you are really on the safe values for temp.

Maybe take a look also at the CPU fan settings in the bios if you want to decrease temperatures at the cost of more noise or the inverse, lower the noise at the cost of increased temperatures for the CPU.
