Overclocking a Intel 5930k

[mansonn]

Hello everyone. I currently got my new rig 5930k with dual 980TIs on an Asus x99 Sabertooth.
Since i got a H110i watercooling the cpu, i should maybe do some minor overclocking since i play alot and the cpu core clock is only 3.5.

What do you consider is a minor and safe overclock? Maybe 4.2?

And how do i start it? Put in bios sync all cores on 42 multiplier and thats it? Should i manually change the v core?

If someone could explain, please talk to me like im really stupid haha

This will be my first overclock

 

OBS: I have looked on the web about overclocking so much but i simply cannot understand... People start talking about pll,bslk etc etc..

Im completely lost

How about you just follow the instructions? Start at 5:40

I ´ve seen it. But he says to put 1.3 voltage. And if it passes, should i just leave it at that? Shouln´t i try lowering it? Like i said, im really stupid with overclocking.

put the voltage to 1.3v and increase the cpu speed until it crashes. then lower it back down a bit so it doesn't crash.

Depends. If you want, you can just leave it at that. Lowering will reduce heat, but also reduce stability. It MAY make your OC unstable if you reduce it, in which case you should leave at 1.3. BUT, it may also still be solid, even when reducing voltages. If that's the case, then you should reduce it.

 

If you'd like fine tuning, lower the voltages as much as you can (remember to do various stress tests).

You mean the multiplier? Start increasing from 41? than 42,etc..? Ty for the fast reply

Oh ok.. But 1.3 voltage is considered safe? And the multiplier and voltage is all i have to change?Im just looking for a minor oc since i got an awsome watercooler

You are actually doing the other way around: you get a WC because you want to make big OCs, not the contrary.

 

At any rate, yes, 1.3 is considered safe. And if you really don't wanna spend much time on this, just change multiplier and voltages and be done with it. You'd have to invest some big time into getting the max out of your hardware.

yes you can just change the multiplier. i would start at 42 and work your way up from there. i would think you'll hit 4.5-4.7ghz as the 5930k tends to be pretty good. keep an eye on the temps though. if they get over 85c then lower the voltage a bit to 1.275v or something like that.

I dont even want that much. Lets say i only want a 4.2 Ghz,which is pretty safe i would guess, how much voltage do you recommend i put on it?

But when i lower the voltage,i have to lower the multiplier too right?

Cause when i put multiplier of 45, it will always boot up using a 4.5 clock right?

yes. but a h110 should be fine with 1.3v. i would cross that bridge when you get there.

My guess is that unless you got a very bad chip, aiming directly at something like 4.3-4.4GHz isn't that far-fetched. IMO, just try 4.4GHz with 1.3V. The H110 is completely capable of handling that kind of volts. My H110 keeps the 5960X I have at 4.5GHz with 1.32V at happy 80-85C under stress testing which is perfectly fine. 

 

If 4.4GHz proves to be unstable, just either bump up the voltage by 0.01 increment until you get it stable or, back off the multi. Also it is a good idea to check the CPU Input Voltage as on some motherboards it comes preset at a too low of a setting causing instability while overclocking. Anything from 1.90 to 1.92V is considered the sweet-spot. 

 

You only need to touch the BCLK if you want to mess up with the RAM clock speeds and stuff. However, I strongly recommend not doing so, since you seem an inexperienced overclocker and overclocking RAM is not for the fainthearted, since it involves much more than simply increasing its speed and voltage. It is also very dependent on the type of RAM you have installed in your rig and if said RAM is officially supported by your motherboard. 

 

If you have any more questions, feel free to ask!

Thank you so muchy for your help.Thanks to everyone in this post you really helped me out.

I was able to get 4.3ghz at 1.2v is that good? I stress tested for like 20 minutes with a maximum of 71C.

Should i try to get 4.4? Thx in advance sir

The faster the processor, the better your PC performs. I would definitely try 4.4GHz. However, since you have it somewhat stable at 4.3GHz with 1.2V, you can try the 4.4GHz with 1.275V. My guess is that it will be sufficient. After that stress test the processor for for a minimum of 6 hours (12-16 hours is usually recommended though). For stress testing you can use either Intel's own software - Intel Extreme Tuning Utility, or Aida64. I usually use Aida64, but that is personal preference. After you pass your stress testing, if you still want to tinker around with your system, you can move on to overclocking the cache of your 5930K. 

 

With overclocking cache the values that matter are:

 - CPU Cache Ratio - That is basically the multi for the cache. 

 - CPU Cache Voltage - Self explanatory, what this is. (Maximum safe amount of volts is 1.3-1.35V)

 - CPU Input Voltage - However if you have previously set it to 1.90-1.92V you should be good to go. 

 

Overclocking the cache is like overclocking your processor but easier. The reason for this is that instability is almost always immediately shown.

If you want to have a bit of extra protection checkout the Intel performance tuning plan:

 

I am experienced and now use it so I can push 1.425V

1.425 is in the hardcore degrading stage...

Aye; thats why I am using it with PPTP; new chip in ~1yr or so when there are better batches or broadwell around..
