Running all cores at 4.2GHz degrade the CPU ?

Recommended Posts

Posted · Original PosterOP

Hi

 

I found in my motherboard X570 that I can select optimal CPU performance option for my 3800x and after I select it I found that in fact it adjust multiplier to 42 and I dont know if voltage changed it is at 1.29v . Will the cpu degrade because of this ?

As far as I'm aware there's no direct inherent risk to running at higher than stock speeds.  The issues come in through indirect means - to achieve those speeds you may need more voltage, and this can either harm the chip directly if you exceed roughly 1.35v (varies depending who you ask), or indirectly by simply making it too hot (but this can be solved by having a better cooler).

If you can read this you're using the wrong theme.  You can change it at the bottom.

so I still have room to raise current voltage up to 1.35v and make it run at higher speed ?

Max safe voltage (in short bursts) for Zen2 would be 1.425v. For long term I would say no higher than 1.375v.

 

Zen2 out of the box will use ~1.51v for lightly threaded stuff when it boosts to 4.6-4.7GHz, and that’s out of the box.

Provided that you can cool it at that voltage, I suppose so.  Personally I might hold it to 1.3 but as I said, different people will give you different numbers.  If you want to be super safe, I would feel reasonably comfortable claiming that virtually 100% of people would say that 1.25 is 100% safe for 24/7 use.

 

Also, 4.2 is far from pushing a 3800x.  I know a 3600 that's doing 4.4 all core on 1.25v.  Feel free to at least try for the max rated boost and go from there.

If it boosted up to 4.6-4.7 I would shit my pants, and if it’s consuming that much voltage I would be worried too.

Yeah I personally dialed mine back to not go over 1.375v because those short bursts can’t exactly be good for it, but it is supposedly normal stock boosting behavior.

 

But you have to remember that’s on single  and dual core boosts, it will NOT draw that much on all core workloads or for very long. Most of the time it will stabilize around 1.35-1.4v

I’m able to keep my 3600 at 4.4ghz 1.35v stable all day long, highest temps it hits is in cinebench r20 but I haven’t passed 85c, with a hyper 212, I would say I’m quite lucky.

That’s a really good 3600 for all core, so congrats on that. My 3900X I just let PBO do its thing and it’ll mostly do 4.275-4.325GHz all core with around 1.28-1.32v roughly, but when it boosts a core or two to 4.5-4.625GHz it’ll go to 1.39v but usually never over that. I mainly just focused getting my RAM to 3800MHz (16-16-16-36) with 1900 fclk from its stock 3600MHz and that was probably the biggest jump for me in terms of performance.

 

The hardest part was probably stabilizing 1900MHz fclk as that I had to significantly adjust the voltage.

 

-Edit: I forgot to mention i’m on Corsair H100i v2, so temps are largely in check as I have the fan speeds controlled by my fan controller.

in previous experiment I got same numbers with 3800x , 4.4GHz at 1.35v but with stock cooler. The stock cooler of 3800x is completely different it has copper pipes and many heat dispensers, it is very similar to my Noctua U14 but in horizontal position. However I really afraid and worried to work on 4.4GHz all cores again.

how you do it ? I cant do my 3200 RAM to 3600. I have gskills ripjaws v

The cooler (wraith spire?) has copped heat pipes too, it just wasn’t enough for stable folding, I highly recommend that you check your temps in a bench mark as 4.4ghz can’t be healthy on the stock cooler.

So return to 4.4 on your responsibility ? :)

No I was just saying, 4.4v on the stock cooler can get toasty.

4.4GHz at 1.35v
