Initial vs Eventual CPU input voltage

Hi, I have my i7-4790K OC'ed at 4,5GHz both core and cache.
Core voltage set to: 1.270
Core cache set to: 1.250

Initial CPU input voltage at: 1.990
Eventual CPU input voltage at 1.990


Does it look good, or am I doing something wrong?

Am guessing you are talking about the the voltage for your motherboard.

more info required from you.

Like what test you did and what heat you are at ect. Check some guides on YOU TUBE. If something is not clear after that. You can ask more specific questions.

GL HF on your OC !
Try more, Try harder, Try and previal

Hi... a bit of an update.
I have done some changes since last time I posted... I am now at VCore 1.280 and Core cache 1.260 (still 4,5 GHz)
I also upped the Initial and Eventual CPU input voltage to 1.2020

Reason I did is I am running BOINC-projects... I had a crash since I posted my first in here.
My CPU temp is now at 33-34 idle and while I'm running BOINC (stable now) my temps reaches around 60 and everything is stable 🙂

UPDATE #2... (about my 4,5 GHz OC)

There's no one speaking in here. I just made a few more changes...
I've been stresstesting my i7-4790K for 20 hours now without a crash and I'm running CPU cores @ 100%

Temperature: 88C (full load)
Temperature: 32-35 (idle)

Cores: 45 @ 1.290
Core caches: 45 @ 1.270

Initial CPU input voltage: 1.2060
Eventual CPU input coltage: 1.2060


Reson I'd like some feedback is that I know some people might think my Initial and Eventual
voltage might look very high, but the fact is, my system will crash if I'm around the 1.9's!

Hi,
Have you run realbench ?

Haha, went back to Initial and Eventual to 1.990 for better temps and also the instability before was only becasue of not enough voltage to the cores. I now have them set on 1.300 and core cache at 1.280. Perfectly stable now and even cooler. I've been running BOINC @ 100% for 17 hrs now and counting... I feel very satisfied with this now. Also my motherboard keeps cool at ca 23 degrees.

Battlefield 1 gives me crazy good FPS too, if that counts on ultra 😉
Also, thanks for the link. I will check that out!


Funny fact...
I actually built this rig in January 2015 but I have been... *blushing* using a bit of a too low voltage setting before and didn't realise it until now. The only thing I've upgraded is the GFX card cause my GTX Titan Z started burning the other week lol...

Hi,
4790k is supposed to be a great oc'er
You're pretty much on a basic oc x45
I'm not aware of the terms you're using
Crank the vcore up[
vccio & system agent voltage and enjoy

Here's mine sometimes you just have to unleash the beast no need to get fancy 🙂
