Is this typical?

[flibberdipper]

So in order to try and keep temps down (and the fan speed on the stock heatsink) until I can get my CM Hyper 212 EVO, I dropped the voltage on my G3250 down to 1.000v. Is this fairly typical? I've only played with the voltage for 10 minutes at the very most (trying to figure out the UEFI BIOS and stuff, I'm a little new to this), and so far I'm impressed.

What is the stock voltage?

What is the stock voltage?

Stock voltage of G3258 is 1.267V.

Undervolting can reduce temps, at the cost of reduced stability.

You should torture-test the system and see if it crashes your os before staying at a lower voltage level.

[flibberdipper]

What is the stock voltage?

No clue. I wanna say 1.2.

 

why are you worrying about temps my friend overclocked it to 4ghz on the stock cooler and undervolted it (24 hours stable with intel extreme tuning utility). it never breaks 50C. in answer to your question yes that voltage could easily run that pentium.

The other main reason is I'm using a crappy HP power supply which only has 1 4-pin EPS connector... I really don't wanna burn out my precious.

 

Stock voltage of G3258 is 1.267V.

Undervolting can reduce temps, at the cost of reduced performance and stability.

You should run prime95 and see if it crashes your windows before staying at a lower voltage level.

Prime95 and Haswell/Devil's Canyon don't mix. Makes voltage go wonky. Right now I'm watching 4K videos in Flash with IE.

[WoodenMarker]

It's normal to be able to run stock clock speeds at 1v or less. You should be impressed if it can go below 0.9v

Stock setting is auto.

Chips can have different stock voltages.

Trying to get under 1.0V would be good.

you guys bash the stock cooler on the pentium way to much ask @vishnureddy17 how his is overclocked on the stock cooler.

We're not bashing it...

[imthewalrus]

Have you done any sort of stability test? It is very common for it to boot up and do everything fine but most of the time once you load a game or stress it, it may crash. 

[flibberdipper]

you guys arent directly bashing it but your making it sound insufficient for what its meant to do. You might be hurting its feelings.  

Are you serious?

I was playing 4K video in Flash. Now I'm trying to figure out why my damn wireless card is being an asshat.

Playing 4k video does not demand anything on the CPU, the iGPU or GPU does all the decoding. Run prime 95

I know. And Prime95 makes voltages go nuts. Come on peeps.

 

Even then, nothing is really set up, and I'm trying to do Windows updates.

Prime 95 doesn't change your voltage, your processor will never go above the voltage you have set on the BIOS, if it does it is probably by a small bit. Your CPU should be able to withstand prime 95 even with the stock cooler, the pentium aniversary I had with the stock cooler never got over 62 without overclocking.

Prime95 is perfectly fine to use, you just have to set your voltage to manual/constant/override/static, or whatever your motherboard calls it.  Its the people that don't do this one simple step that have problems of overvolting and insane temperatures.  Be a pro and use manual voltage to stress testing.  Anyways, if you want to find out what the stock voltage was, go back into BIOS and hit F5 to reset to default.  See what it was and report back.  Also, the stock cooler is plenty for a Pentium.  This is only a dual core chip that doesn't get very hot.  You can probably push 1.3v and still keep temps within the safe range (<85C).

In that case, I would have been fine. I ran 10 runs with Intel Burn Test (1024MB), and it was fine. Hottest core was 47C, I want to say. Fan speed topped out at 1250-ish RPM. But I really don't wanna burn anything out.

[harrynowl]

Yep. My 4690K does 3.4GHz @ 0.86v.

 

I was kind of blown away coming from 1.4v+ AMDs

[Faceman]

Every chip is different and characteristics of each are unique. For instance my i5-4670k is able to underfoot and overclock at 4.2Ghz, but if I want 4.5Ghz I need to add more voltage than stock. When overclocking you have to figure out the characteristics of your specific chip and go with what works best for you. Lots of trial and error to say the least.

Yeah. Now it's just sitting at .951 volts. Haven't bothered to go lower.

[WoodenMarker]

hell no it is not 1.267 its around 1.1

The stock setting is auto and will vary from chip and motherboard.

Prime95 is perfectly fine to use

I've been told by Slick and others who know better that Prime95 isn't exactly safe for modern cpus and that a proper explanation of why is super long.

avoid turbo voltage by setting voltage to manual! Its adaptive voltage that causes overvolting.

He's not referring to the 'turbo voltage' setting but the new turbo system that modern cpus use. The new system is better but not for 'synthetic BS' like Prime95.

Its negated by using manual voltage.  When you use adaptive voltage your voltage goes up by as much as .1v.  When you use manual voltage it will only go up by .002v.

 

Prime95 is perfectly fine to use, you just have to use the correct voltage setting.  For any stress test, it is recommended to set voltage to manual.

 

If people don't want to use P95 because they don't like the high temperatures or they don't know how to safely use it, that is fine.  But to say P95 is bad is not true.  Its the person sitting in the chair(PSIC) that causes the problem.

 

I personally like P95 because if I'm stable in P95 with these settings:  Threads = 4, Min FFT Size(in K) = 8, Max FFT Size(in K) = 4096, Memory to Use(in MB) = 1600, Time to Run Each FFT Size(in Minutes) = 3, and I run this for 20 minutes, then my overclock is rock hard stable.

It's not a motherboard setting but a different voltage system. Go ahead and take what I mentioned with a grain of salt--I haven't read the supposed ~60 page explanation from Intel that would explain why Prime95 isn't exactly safe.

Intel uses an iteration of P95 in IBT and XTU.

[flibberdipper]

Well guys... I'm at .922 now. Still gonna try to push lower.

 

 

EDIT: Aaaand... I'm happy.

Thats an awesome underclock.  Have you tried overclocking it yet?  It probably clocks like a dream.
