stress test g3258

[Babtsa]

Hi there!instead of overclocking my new g3258 i ran a stress test yesterday and i realized that when everything was on stock my cpu temps were too high..(about 68-70C)..im using core temp on windows 7...i have X.m.p enabled and i have r9 280 ..is it ordinary?

[MrBucket101]

You didn't give us any additional info

 

what stress test, what case, what cooling setup.

 

We need A LOT more info

[Glenwing]

Hard to say if those are normal temps or not if we don't know whether you're on a stock cooler or liquid nitrogen

[Ostwind]

70c is not dangerous.

[Babtsa]

well sorry for the 1st post....i am in stock cooler on a corsair 240 case with z97 gryphon motherboard and r9 280 vga...+thermaltake 630se..i ran it through prime95

[Glenwing]

For a stock cooler, seems like pretty normal temperatures under high load to me

[Babtsa]

i read too many posts that this cpu can be overclocked with stock cooler over 4.0 ...but how? if i get 70C on stock how i supoose to overclock it over 4.0?

Something Is definitely causing trouble, it's a matter of finding out what.  You should be at around 27c stock.  Might have to go through the routine; update bios then reset bios defaults, make sure HSF is installed securely, fans working & use right amount of thermal compound.

is core temp a reliable program?i've just set up this pc and i used the stock amount of thermal compound of the stock cooler

 

27C on prime95?really?

[Newbisgood]

Core temp is reliable.

No. 27C under synthetic load is not normal. @Newbisgood seems to have made a mistake. When the room temperature is ~20C, you can't expect the CPU to be at 27 ffs.

70C in prime95 would mean about 60C under heavy load in a real world program, e.g. decoding a video. Which isn't that bad.

You might not need to increase the voltage in order to achieve higher clocks, so you might not get higher temps. Just try overclocking, anything that is under 90C in prime95 would be acceptable FOR ME.

when i run prime95 should i put fans on max load? i wanted to go for 3.8 or 4.0 with my stock cooler but now i'm a bit worried!

You shouldn't be worried. If it is still only 70C, you have some headroom to increase the voltage. If you increase ONLY the multiplier for start, you won't see much heat increase.

So try to increase the multiplier first, then see if it's stable. If not, increase the voltage a bit, and repeat until the stress tests become too hot. The web is full with Pentium "K" overclocking guides

The way I've always done and recommended overclocking is boost the clock till it fails a stress test, then boost the voltage until it can pass. 

Also, if it goes up above 80C with a mild OC (3.7ish), reapplying thermal paste and the cooler can't hurt. 

*EDIT*

Let the CPU fan curve take care of itself or boost it a small amount, just make sure the rest of your case is getting rid of hot air. 

Do you know about positive vs. negative air pressure in your case? 

[ThomasD]

What sort of case fans are you using?

 

No air cooler works well unless fed a steady supply of fresh, cool air.  

 

So even before I changed the stock cooler I'd try adding additional case fans - it's cheap and easy.

Agreed, however the corsair 240 comes with 2 intakes and 1 exhaust, which are pretty descend for a freaking Pentium build . So I don't think that's the case here.

The temperatures aren't that high, and we don't know anything about the ambient temperature.

[runit3]

1) don't use P95. Go with AIDA or Intel XTU, much more reasonable stress tests.

2) Any temperature result is meaningless without knowing the voltage. 70C at 1.3v is good, 70C at 1.05v is terrible.

3) Make sure your voltages are set to manual for all synthetic benchmarks.

Yes, that is what the case comes with, but until he says that is what he is using then it's just an assumption.

 

For all we know he bought the chassis used and the prior owner stripped the fans.

You're right. Assumptions are a bad thing.

[Newbisgood]

For me when using prime95 under full load I'd get about 56C.

That's a pretty terrible temperature for Prime95. My G3258 would run in the 50s on the stock cooler at stock speeds when running Prime95 SmallFFT (their hottest stress test). It didn't start hitting the 70s until about 4.2 GHz and hit the low 80s at 4.4 GHz (I didn't want to push it farther). It sounds like you lost bigtime in the silicon lottery. Another reason to never recommend the G3258. 

[vembutech]

68-70 C are not much more harm to your PC. Change the thermal paste and check the temperature is reduced or not. 

[Babtsa]

Ηi again! Well i overclocked my g3258 to 4.2 ...i changed only the cpu ratio to 42 and nothing else(+xmp enabled) can i reduce Vcore now for better temps?i didnt changed anything on V...but in cpu z it says 1.224V ..max cpu temp on realbench is 77C

[Babtsa]

plus i dont want to overclock it further because i am in stock cooler and it is summer!!
