4790k and over clocking

[JBIZZL3Y]

Hi everyone, happy new year to you all,

 

me and my brother are putting a PC together (which will be for gaming and video editing) and are thinking of using the i7-4970k, as this is our 1st build we are wondering if we will be able to go into the bios a few months down the line and over clock the CPU once we feel a little bit more comfortable doing so? or if this is not such a good idea?

If you get a CPU like that, I would be INSULTED if you didn't overclock it at least a bit

 

Just make sure you get a good cooler and you can really push a lot more out of those. Don't be nervous, there are many safety feastures that prevent you burning it out. Just follow a guide somewhere

Yeah sure its not a problem, especialy with 4790k i have it myself it was a treat OCing it, 4.4 is base overlock with a guide ocing it to 4.6 with good cooling is easy as hell 2/10 i would say the level how hard it is. With proper AIO, or waterloop i am sure getting it to 4.8 is also very posible with a little bit of playing around with voltage etc

Go for it its a magnificent CPU for gaming also. 

 

But if you want to have temps rly rly down, like 45ish get 240 rad AIO

 

i have air cooler CM GTS V8 which is kinda bad for that money i just love the looks and i got 4.6GHZ stable out of it with temps maxed at load at 82 degrees which is acceptable

Thank you for the advice! Having watched a couple of guides I have a few questions, does anyone have/know of a good guide I could read as I'm getting a bit confused about a few things,

such as how OC'ing the CPU will affect other components.. I don't intend on OC'ing anything else i.e ram (gpu will come factory oc'd) but will the ammount I oc my cpu affect how it interacts with the ram, gpu etc? Or the speed of the ram I can use?

I don't know if I'm totally lost here sorry.

Thank you in advanced for reading these ramblings... We'll get there in the end.

Nope ocing your cpu doesnt affect your other components, its only affects the effectivity of handling for example the extra ram, so if you oc a CPU and add extra ram that ram is to be faster used making the for example Rendering procces faster. 

 

The only problem is the more you OC you CPU the lifespan of it can decrease but ocing 4790k its ok because the K stands it was made for OCing just remember the magical frequency when you are dealing with shorter lifespan is around 4.8 so i would recomend ocing max to 4.8, 4.7 just to be sure It will run as long as its cool and with propper voltage just fine as would stock one.

 

Now to RAM dont oc that, its not realy needed, you can check linuses videos just on that, ocing ram doesnt increase the performance by much, if by any %. +1000MHZ 

may increase the speed of some tasks by some 1% thats nothing so dont do it its too time consuming to get everything right so it will run crashing. If you got it by accident OCed and everything is stable then sir good for you leave it  

 

And to the GPU now, even when it comes OC from the factory there is nothing said about not OCing it a bit more

Overclocking is easy nowadays. What UEFI BIOS will you get? Asus, Msi, Gigabyte, etc.

Thank you for the advice bughtoo that clears a few things up! I think Ill still be watching a few of linus' guides before we take the plunge though!

We'll be using asus bios (maximus vII ranger) our full parts list can be seen in this thread:

The only time OCing your CPU affects RAM is when adjusting the base clock (bclk) of the system. RAM runs off the bus speed there; therefore raising the bclk will raise the RAM speed. You would not be aiming to adjust bclk however; you'd be aiming to adjust the core multiplier of your CPU. If you do not wish to use the BIOS to overclock, another utility is Intel XTU which is free.

Hi i don't know if it fits in here but i'm having trouble with my 4790k. I can run it at 4.6GHz with 1.180v with manual voltage (be quiet! Dark Rock 3 73°C) but when i'm setting it to Adaptive voltage it pulls between 1.213 and 1.280 volts and then it starts to get to 90°C but i don't know why it's doing it.

 

hope some one can help me out :-)

[bughtoo]

what adaptive voltage did you set? what offset did yo uset? everything is on default?

[MrTweedels]

I set adaptive voltage to 1.200 the offset on auto and the rest on default.

[bughtoo]

set the offset max to 0.100 thats why its going of the hood up

[MrTweedels]

ohh thank you so much

[bughtoo]

ohh thank you so much

sorry

set it to 0.05

[bughtoo]

my bad 0.1 wouldnt change anything set it to 0.05 that should alright if its still to much for the heat, set it even lover

[MrTweedels]

hmm didn't help

 

When i set the the core voltage to 1.180 and the offset to 0.05 it still goes to 1.280

[bughtoo]

Oh Rly? thats weird and did yo uset it in bios? or in windows in some tune program?

[MrTweedels]

i set in AI Suit III

[bughtoo]

oh well i am lookign at it right now i have the same thing when i set voltage to 1.2 and offset to 0.05 during aida64 performance test i got 1.3volts i guess its the motherboard preinstalled capabilities to increase it so it is more stable.

[MrTweedels]

Well that's unfortunate.

[bughtoo]

but trust me, the bigger OC the bigger voltage you need, the more voltage you need the more heat it outputs, the more heat it outputs the better cooler you need

So OC only in the range of  your cooling posibilities
