oc Can’t Get my 4670k to 4.8ghz

[LeviBW]

My 4670k will do 4.7ghz on 1.31v but as soon as I try 4.8 I get nowhere. I’ve given it up to 1.4v and it still won’t pass cinebench at 4.8. 

 

Anyone know of any tricks or tips to get it stable, right now I’m only increasing Vcore, are there other voltages I should be messing with

Your CPU isn't going to do 4.8.

[Enderman]

Buy a new CPU.

A 7700k or 8700k should be able to do 4.8 easily.

I’ve gotten it to 5.8 on LN2 so obviously it can. 

 

Right now im using a different board and I can’t seem to figure out why it won’t hit 4.8 on air. I think I’m forgetting a setting

That’s not the point. This isn’t my main pc. I have a 7700k system for my main rig. 

 

Im just benching this chip for Hardware Points on HW bot

If it takes 1.4V to boot, you aren't hitting 4.8 period.

 

LN2 is irrelevant to this.

You have reached the limits the cpu is capable of. Thats how far the cpu lottery let you go. Be grateful it went that far. I had a 4670k that couldn't get past 4.0ghz without using 1.45v. Way to high and way to hot for daily use.

LN2 is irrelevant to this.

First of all it boots at 1.32v it just crashes under load. Second, the fact that the chip can hit 5.8 is relevant because it proves that the chip is capable of higher clockspeeds

Isn't 4,7GHz pretty nice OC for that generation?

And do you even need those additional 100MHz out of your CPU?

 

It's just like my R7 1700. It works fine at 3,825GHz 1,35V, but won't post at 3,850GHz even if I put 1,45V on it.

Sometimes you just hit the wall. But that wall can be taken down with Ln2 like you said ... but that require high voltage and decent VRM.

LN2 is irrelevant because you're removing heat from the equation, you should know that if you've done LN2.

 

You also said you've given it 1.4V and it still crashes, you're not hitting 4.8 with it. Period.

For everyday use of course 100mhz is not worth the heat output and power draw. But I’m overclocking this chip specifically for an over clocking competition and right now there is only a 0.75% difference between me and the number 1 guy so I kinda need the extra 100mhz

Heat isn’t in the equation right now the chip doesn’t exceed 58c 

 

Also I got it working  sooooooo.... looks like you were wrong on this one 

 

1.39v 29 multiplier 167 bclk = 4.843 GHz

Let's see how long that's "stable" for.

Seems pretty Stable to me  - real bench stress 4hrs, xtu stress 2hrs, pass cine bench, pass firestrike and timespy, pass CPUpi. Max temp 78c
