How do you check if the OC of a CPU is stable?

[podkall]

If I raise clock speed and little bit of voltage how can I tell if it's enough voltage?

 

Is the system not crashing while playing games enough of an indicator or is there something more to check?

 

Can not enough voltage hurt the CPU or performance in games?

 

Thanks.

A lot the time you won't even need to raise the voltage. Only raise the voltage if you run into instability. There are a number of programs that stress the CPU pretty well, the one I tend to use is Prime95, but Aida64 is another big one out there.

That's the first hurdle, but again, you want to run through a stress test. Long blender renders are another one that stresses the CPU a lot.

The voltage is really just to stabilize the CPU. Less voltage is actually better for the CPU in the long term, but not enough will usually cause crashing, so performance in games will therefore be pretty bad.

There are many, many OC guides on YouTube and the internet, and I couldn’t possibly derail everything here for you.

 

To overclock correctly, stably, and safely, it takes a good amount of reading and understanding. Thankfully, the internet is full of information. Don’t just overclock because you heard the word and think you can wing it, that’s a recipe for a fried CPU. You need to understand what settings your changing, have a plan to test for stability and how to adjust settings to gain stability, check temps, and most importantly check voltages.

 

Google around for OC guides for your socket and chipset; there will be lots of articles to read. Then once you sorta get what’s going on, you can start fiddling with BIOS settings

the BMW one?

Can side effect of not enough of voltage be occasional stuttering when playing game?

I already rolled my silicon dice, it's pretty decent as you can see in my signature.

I was asking because I only OC like half the amount for CPU demanding games and don't wanna hurt it in a longrun if if low voltage was one of possible ways to kill CPU, but thankfuly it isn't.

That's one of them

Not that I know of.

Is the question in regards to your sig rig? Ryzen 1200?

 

If so I've overclocked one. 4ghz is about the limit of this chip on ambient temps consuming nearly 1.40v for a steady 4ghz.

 

You probably won't find more performance from it. 

 

Low voltage typically results is a hang up. The pc freezes and sometimes accompanied by a black screen. 

 

Yes you may see degraded performance from a low v-core, but with early Ryzen chips I noticed the reference clock which should be 99 to 100mhz will often times dip even below 95mhz. In this case I was able to measure the performance loss with benchmarking.

Blender is not at all a stressful enough application to prove stability. A very unstable OC can pass blender. Unless you have properly stress tested your CPU, you don’t actually know where your chip lands… if it doesn’t pass blender, it’s guaranteed not stable, but passing it does not guarantee it IS stable. 
 

Not enough voltage could be stuttering, or crashing, or BSOD, or memory errors. Plenty of ways for it to “fail” when not stable, which is why properly stress testing is an integral part of the overclocking equation.

 

Low voltage I don’t believe can hurt the hardware, but it can cause corruption of software… no reason to “only OC half of what the CPU is capable of”, just have to actually thoroughly stress test and being the bolts down as low as possible to actually be stable. Assuming temps are ok at that level while in your every day workload, and voltage is within what is considered safe limits, the chip will be fine. My old 9900k ran at 98c while in aida64 FPU stress test for 4 hours, low 90’s with normal default Aida, and low 80’s for blender (blender isn’t very stressful….), but in the 60’s for games. If I was always doing renders or number crunching, I would have backed it off from 5ghz to something lower, but since my main use is gaming, and my voltage was not high but I had a hot running chip while in stress test but temps were fine in gaming, I stuck with 5ghz without issue. Just because the chip is hot in unrealistic stress tests doesn’t mean it’ll be dangerous since you are never in that type of workload...

Some things in my tool box for testing:

 

Linpack Xtreme

OCCT

TM5

SuperPi 32M

Some other crap.

 

Not Cinebench lol..

Well playing BR games gives my CPU quite the effort, basicaly constant 100% utralisation

Not Cinebench? damn, I thought it was decent since it runs the cpu at highest possible speed and utralisation, and takes little time

like for a quick test could be fine right? not for definitive answer of stability ofc

 

Btw @freeagent @LIGISTX values when Cinebench was running:

[freeagent]

You should use HWinfo64... its uber gooder.

Just because the CPU is at 100% utilization doesn’t mean it is being heavily worked. It’s all about the actual wattage load being placed on the chip. Games are no where near stressful enough to prove actual stability, and CB isn’t either. It’s just not enough of a wattage draw. If that package power is correct in your screenshot, it’s only pulling 65 watts of power. Try asus real bench, or AIDA64 with only the FPU option checked.

There is no "One" thing that can completely test it, as long as the system is running fine with no errors or crashing it's fine.
The usual suspects are Prime 95, OCCT and such but you have to be careful, some tests you can use are capable of doing damage to a system like Furmark.
Do not use Furmark and if you do, you've been warned.

This is the current and complete list of benchmarks ran at the bot: Overclocking, overclocking, and much more! Like overclocking.
Lots of stuff to try with some of it being free, some not but whatever tickles your fancy you can go for it if you want.
