Hi all,

I've had my i5 3570k for nearly 5 years now (in July), and it's been serving me good at 4.3GHz around 1.21v.

Over the years I've done small upgrades, new GPU, RAM and HDD/SSDs but CPU's always been the same.


I'm at that stage where I've been pushing every component of my PC (in all honesty i'm just looking for a reason to build a new PC, and so pushing my PC as much as I can until it breaks).


Current specs:
i5 3570k @ 4.3GHz - 1.21v
MSI GTX 970 - 1530MHz core, 2000MHz memory, custom bios - 1.275v
RAM @ 1866MHz (from original 1600MHz XMP) - 1.64v


My goal now is to push my CPU even further.

At 4.3GHz 1.21v the temperatures usually max out around 67-70 when playing demanding games such as BF1.

I've managed to get it to 4.5GHz but had to push the voltage to 1.3V and that's increased temperatures to around 77-80c. Seems stable. [BF1]

I tried to push it to 4.6 but that would blue screen until I ran it at 1.37v, the temperatures were then more around 81-83c [BF1]. I believe around 87-95c when stress testing with x264.


I want to keep pushing it more, and really not too concerned about my CPU degrading, what I'm trying to ask is how much should I keep pushing my CPU?

Would it be best that I stay under 80c when gaming and be happy with my 4.3 > 4.5 increase, or should I push it and keep temps below 90c (when gaming) and aim for 4.6/4.7GHz. From what I've read around, 80c is usually the limit.

Another thing I did notice with 4.6GHz around 1.35v is under HWiNFO I did get a fair amount of Windows Hardware Errors, when stress testing with x264, but with 4.5 @ 1.3v I wouldn't even get close to that many errors, but very very rarely got 1 (only got the error when I was running x264 & trying to do other heavy tasks (opening my chrome browser and watching TwitchTV at the same time).

Should I be concerned about this, or is this just showing the number of errors that windows could recover from and I'm not completely unstable yet but close.

I understand that I'm not really stress testing my PC the correct way, but I'd prefer to just overclock and stress test using games. If I ever do crash I know what I'll be dialing down.

Apologies for my messy post.

Thanks for your help!

You can push it with vcore until either the CPU/mobo turns off the computer or it fries.

It is best to keep it under 80C so you've hit that wall and I doubt you want to pour more money into it for a better cooler/TIM etc...

Here is my Bios to where I got it stable @4.6GHz all those years back:

Save it and use it as a back-up computer and also store all your older games on it.

Thanks, I'll keep it at 4.5, had to bump voltage to 1.3v worriedsmiley.gif to keep it stable.

I may try push it further if I can bring temps down, or during winter season. redface.gif

Does anybody know if I should be hugely concerned if I get "Windows Hardware Errors" on HWInfo. (I only get them at 4.6/4.7)

If these errors are not much of a problem for gaming etc, I could try push for 4.6, 4.7 at 1.35v/1.37v

Currently, i'm hitting around 74-76c max temp when gaming at 4.5GHz 1.3v

I'm tempted to delid but at around 4.7GHz I couldn't get it stable, not even at 1.37v. I'm guessing even if I do delid, I shouldn't be pushing it to 1.4v, seems quite high.

Im running mine at 4.4 - 4.5 GHz at 1.38v fixed in bios (1.316 idle 1.368 load in system) for a year now without issues. Its a realy bad chip, hot as hell... Oh, after chainging the mobo ive gained another 100MHz (from asrock z77 extreme4 to banging MSI z77 Mpower)

Ryzen 5 2600 | Asrock x470 K4 Fatality | 2x8 3000Mhz DDR4 | GTX 1660 Ti | 480GB SSD | IN WIN 303 | be quiet! STRAIGHT POWER 10 500W

Oh damn, thanks for that. Now i won't worry as much haha.

Still curious about HwInfo WHEA errors if anyone can chip in. I've looked around but not getting any solid answers (a lot of the posts are referring to GPU Memory errors when i search)

You should avoid them, it's a sign that the CPU is a little unstable which will lead to further problems eventually

I don't believe in "good enough"~!!

240hz / gsync / low persistence is AWESOME

I've been running my 3570K highly overclocked for over 4 years now. thumb.gif

The first 2 years I was still on aircooling but it happely ran @4.5GHz (around 80° loaded).
Now I'm fully watercooled and its running 4.7GHz at a max temp of around 65°.
CPU has also been delidded and there's liquid PRO between the cpu and heatspreader.

Specs:

3570k @ 4.7GHz (1.365v)
Asus Maximus V formula
Gskill 4x4GB @ 2133MHz (1.635v)
2x GTX980 (SLI)

Tbh I would delid it and squeeze every last drop of performance out of it ! tongue.gif
Using it for gaming mostly and the cpu can still keep up with 2x GTX980's in SLI.

I'm still happy with the performance and will probably use this setup for another couple of years before upgrading.
