G3258 OC - is this normal?

[BallOfPanda]

My Pentium G3258 was running at 4.3 GHz stable at stock voltage (1.25v). To reach 4.4 GHz stable I had to increase the voltage to 1.33v. This seems very excessive for an additional .1 GHz, so is this normal? Should I just leave it at 4.3 for the sake of heat and longevity? It is watercooled, so heat is not an issue, but cooler is always better anyway.

youre doing something wrong because if you had actually set the voltage to 2.33v then your CPU would die instantly

Fixed. 1.33v.

yes, this is a normal function. not all silicon has the same voltage patterns. luck of the silicon lottery.

some can delay voltage to multiplier jumps, some just get hot quicker using the same voltage/coolers.

ah ok lol

 

at some point a CPU requires a lot more voltage for very little gain

thats when you know you reached the limit

and no, .1GHz is not worth it, stay at 1.25v

Alright. I'll probably do that tomorrow.

Interestingly I almost made the same mistake but while ACTUALLY changing the voltage.. I very nearly set it to 1.90v

It just seems amazing to me that an extra .1 GHz requires a .8v increase.

mine goes 5.2GHz at 1.58v and under load clips 90° on h100i with OE fans at full 12v.

5.0GHz 1.45v under load sitting at 78° on h100i with hyperborea fans at silent. ambient on both is 24°

4.6GHz 1.295v 69°

1.58v? I would never risk that unless by accident

it is a $60 thrashing CPU to see what it is capable of.

Ah, you meant your G3258? I assumed you meant a 4670/90k or 4770/90k. Still, wouldn't risk it for more than a few minutes.

"I tried to go past 5.2ghz."

Me when I almost fed my CPU 1.90v..

This is what the overclocking world calls "the wall". It's like @Enderman said. When your next multiplier takes way more voltage than the last, you've reached that point. Most of the time, it's just not worth it. Maybe for a quick benchmark, sure, but not for 24/7 use. 

 

The exact moment you reach "The Wall" depends on a few factors. Cooling solution, delid/lapping, motherboard/bios, silicon lottery, etc. However, one thing is for certain. No matter what combination of board and CPU you use, even with the best cooling, everyone hits the wall. It's just a natural part of overclocking.

Completely normal across all cpus... you usually come to a spot where you moderately have to increase voltage for minimal gains... then you reach a point where you have to realllly crank it up to get gains. I have to go from like 1.362v at 4.3 to 1.45v to get 4.75 out of my Xeon. It's just not worth the extra heat and reduced life in my case. So I run a lighter more moderate OC as my 24/7, nothing at all wrong with playing around with it and saving multiple BIOS profiles.

4.2GHz on a 3.2GHz chip is pretty good though. Not a bad overclocker.

 

My system hit the wall and I literally can't get past it. Mine is at 4.2GHz and there is nothing that I can do to push it past that threshold. I've heard of people taking the same chip to 5GHz with no problem though.

Fed my cpu 1.6V by accident. I can tell you i wasn't stable at my regular OC after that.

[sgloux3470]

This is pretty normal when overclocking.  Once you start to reach the limits of your chip it can take a ton of extra voltage for minor 100 MHz bumps.

 

The sweet spot is to find that spot where the required voltage skyrockets and stop there.  So stick with the 4.3 GHz 1.25 v setting.

same here, i give my g3258 1.4volt @ 4440mhz since a full year now... 60bucks what should go wrong??

voltage/frequency relationship is exponential. 

 

The higher the clock, the more and more voltage you'll need.

Just wondered if you took an i5 instead of G3258 and slap watercooling somewhere down the line.

?? I got the G3258 then a year later added the water cooler.
