Hey there community...

I just wanted to hear your oppinion:
I'm quite new to OC-ing with this recently-made rig, so i was wondering if I did this correctly... (just cranked up the multi to x40) and set the RAM to 1866MHz...

The CPU cooler I'm using is: CM Hyper 212X.
PSU: ThermalTake SmartSE 630W

Is that CPU Voltage O.K. at this frequency or I can lower it. I've read somewhere that this ECS mobo isn't that good for overclock.
I have read here (http://www.tomshardware.co.uk/forum/281579-29-overclocking-2500k-4ghz#) that @4.0GHz it usually is fine operating at Vcore of 1.150V. I can not find the option to manually adjust the voltage in BIOS.

I've ran the AIDA64 FPU Benchs and they're quite close to i7-5820k (6436) and i got 6401. Woow, that really surprised me.

Looking forward for the community response :D

Here is the link from my imgur album of the AIDA64 readings:

2500k is getting a bit long in the tooth! [ but I still run 2600k so it will work ok just not cutting edge n e more! :) Your CPU voltage [vcore] is high for what you are doing [1.356V] Having said that it still should be fine to run all day long at that, provided it doesnt get to hot?! ie if you have decent enough cooling! you will probly be able to run it at 1.2V at 4.0Ghz ! which will help with the cooling too!
i looked up your mb manual and it lists Vcore adj in M.I.B III section . looks like you have quite a few adjustments which should be plenty good enough to overclock just fine!

You also have fast ram for...

You also have fast ram for the time ! listed on your provided pic is your psu 12v which is at 18.351V which is extremely high or an error?
For Vcore i always work on the 10% theory! if you dont go beyond 10% of your default Vcore you should never run into trouble for 24/7 use! :)

max Vcore is 1.5V but the general recommendation is to stay under 1.4V for 24/7 use!
Good Luck !

Thanks for your answer.

I'm not sure about that 18+ reading on the 12V-rail... The computer would already have been shutdowned, due to PSU's over-voltage protection... or something would be fried (I guess). Must be a diagnostic error... I had no app/game crashes, reboots, or BSODs so far.

About the Vcore setting... It is only listed under Advanced - PC Health Status - it just shows the values of different voltages - No option to set them up.

M.I.B. 3 under CPU settings also has nothing I can set, besides the "Voltage offset option"... Seems like I'm stuck with MOBO deciding the voltage by itself. :( Any software tools that are good i can use (it's not really recommended to do it in Windows OS, from what I have read)?
...
I've just downloaded the Intel Extreme Tuning Utility, and it also doesn't offer CPU voltage to be changed (only increased - Additional Turbo Voltage), which i suppose is directly dependent on the motherboard's BIOS settings :(
