Fx-8320 Prime95 problem

[Fideliis]

hi guys.

So a few days ago i made a post about my cpu getting to hot to fast. all the information of that post you can find here ---> http://www.tomshardware.co.uk/answers/id-2742022/8320-temps-rise-fast.html

There is some important stuff in there but I dont want to type everything again.

Long story short i think my cpu temps rise way to fast. You can find my temps in the other thread.

Basicly I want to do some overclocking on my fx-8320 with an h55 closed loop cooler. But whenever i want to test it with prime95. The temps reach 62 package temps and over 60 cpu temps within seconds). I cant even run the test properly. ( in the other thread i said a few minutes but aparently it is a few seconds. They suggested waiting till the thermal paste has settled in. But I see so many people overclocking right a way and it shouldn't rise this fast even with prime95.

So please check out the other thead for more information. I still think its the thermal paste because the temps rise so fast but idle between 35 and 40.

Hardware:
-Case : Bitfenix Neos. 2 Corsair sp120's intake fans in the front.
-Cooler : Corsair h55 Pushing air out in the back of my case as Push/Pull with 2 Corsair sp120's
-Motherboard : m5a97 evo r2.0
-Gpu : Radeon r7 265
-PSU : Seasonic 600w Bronze

Hope u guys can help me

Whats your clock speeds and voltages.

Understand that your CPU operates on millionths of seconds. So to you, a couple of seconds is almost no time at all. But to your CPU, a couple of seconds is millions and millions of instructions processed. And as the node size shrinks, the heat is concentrated into a smaller and smaller space. The FX-8320 is based on 28nm technology. But it can still heat up tremendously in a quarter of a second, especially if all four cores are working hard.

Then consider that NOTHING else will ever work your CPU harder than Prime95 does. Absolutely nothing. So what you are doing with Prime95 is not based on anything that will ever happen in real use. So if you are only getting up into the low 60c with Prime95, instead of worrying, you should be jumping up and down celebrating that it only reaches 60c or so.

Thermal paste that is a good quality paste does not need time to settle in. And I have yet to see a quality cooler that came with bad paste. Yes, some thermal pastes work better with some type of cooler or another, but the differences are just a few degrees, so nothing to loose sleep over.

I don't know where you get the impression that your CPU temperature should not rise as fast as it is with Prime95. That is exactly what the program was designed to do. Work your CPU harder than anything else will ever work it, and as a result of that, to raise the temperatures of your CPU very, very quickly, and to keep them there.

I know what the AMD pages say about not going over 62c or 70c. I like to think that you are safe if your CPU stays below 70c. No matter who makes it. But anytime you are running something artificial like Prime95, you must expect your system to get hot. FAST!

If you mount cooler correctly this can be faulty Corsair h55.
About FX max temps 62C for Cores , 72C for Package.

What's your voltage and clock speed?

The H55 is a mediocre CLC. It runs around 6-8c warmer than an H80i. This makes the H55 worse than several air coolers.

To cool an FX 8 core effectively, you need to invest in good cooling. A budget cooler or CLC will only get you so far.

Also, don't ever use the auto-tuning function in motherboard BIOS for overclocking. They usually use far too much voltage, which will generate a tremendous amount of waste heat.

Hi man

I know prime95 makes your system run very hot. but it reaches 62 package temp in 2 to 10 seconds. wich is the max for the package. how am i suposed to stress test if it reaches the max so fast. they recommend 10 to 15 minutes stress test. But I dont have reach 1 procent of that time. Thats why I am under the impression its running hot to fast.

Also i put new thermal apste on it when I changed my mtoherboard - Artic silver 5. it was my first time applying thermal paste so I made did it wrong but i dont think so . i used the pea method.

Hi .

Ive been thinking about getting the hyper evo but i dont know if it will be that much better + I dont think it fits in my case.

I have turned off turbo boost. i even undervolted the system. Its running 1.3 voltage on 3.7ghz. and the standard settings are 1.35 voltage and 3.5 ghz

I have this Cooler for more then a year already. and in my old case and old motherboard wich was 4+1powerphase it didn't have the problem with getting so hot.

Now i have new case. for my new motherboard because becasue i had a matx case and the mb did'n't fit in that.

-Old case setup corsair 350d : h55 as intake in the back with the standard fan (corsair recommends as intake) one 140 mm intake fan in the front and one 120mm in the top as exhaust.

-New case Bitfenix neos : h55 push/pull as exhaust 2 fans, and 2 front 120mm intake fans. no fan slots left.

HWmonitor shows Cpu temps and package temps, Cpu temps is always higher then package in gaming. but wth prime95 package reaches 62c and cpu also 62c in a matter of seconds.

 

[Fideliis]

Whats your clock speeds and voltages.

Clock 3.7ghz voltage 1.3

Standard settings for fx-8320 are clock 3.5ghz and voltage 1.35

 

[madmatt30]

^ voltage 3.35!!!!! No mate that'll burn a board & chip out in a flash.

All chips have different stock volts anyway.
My cherry picked 8320 does 4.3@1.332v (that is stock voltage on mine) ,@3.7 I could get it down to 1.2875

62c is too high even for a prime test with an h55 - not dangerous but higher than it should be & leaves literally no room for over clocking.

They who?

Let it run for a 10 seconds. See if the temperature stabilizes. There is going to be a point, if you have a good enough cooler, where is does stabilize. But do not expect it to be below 70c on Prime95. Everything else you run should be below 70c, but Prime95 is more than likely going to get your up above that a little bit. Remember, it is an ARTIFICIAL test. I actually do not understand why people worry about Prime95. When you buy a new car, do you take it to the race track and drive it at 150 MPH (240 KPH) to make sure it can? No? Then why do you do this to your computer?

Have you loaded up the games you play and checked the temperatures that you are getting in those? What were they?

And I guess its hard to get your head around the fact that a CPU can jump from 30c to 70c in less than 1 second, but when you slam the accelerator on your CPU to 100% on all 4 cores, its going to get hot in less than one second. At at less than 70c, its warm to the CPU, not hot. I start worrying about my Intel CPU at 80c. With an AMD CPU, I would probably start worrying at 75c. You say you are not getting there.

Sorry man in ment 1.35 stock voltage 😛

And indeed thats what i mean how can i overlcock if it is 62 in prime already. and thats after 10 seconds. So what will the temps be when i do it 10 to 15 minutes if you know what i mean.

but i should be able to with this cooler. at least that is what i see other people doing.

 

[madmatt30]

How hot is your h55 rad to the touch when the cpubis hitting those temps??

I just felt it when gaming. The radiator feels hot but not so hot that i couldn't put my fingers on it. But i have a fan on both sides so i cant feel the inside of teh radiator. I will do it again with prime95 on when i am back home because i have to go now.

Man i keep hitting this shitty solution button This is not a solution.

Let me be clear i Perfectly know cpu's can get so fast in a matter of seconds. I am just asking here why I am not able to do a stresstest within these limits of the cpu this is the first time using this program and i am looking at guides for overclocking wich all tell me ot do a stresstest for 10 to 15 minutes. And i am not shure if letting it go higher then the max temps for the fx8320 is a good idea, Not everyone knows everything about cpu's and other stuff that you know. please consider that.

In games the max i have seen was in guild wars 2 and advanced warfare at 60 to 62c for the cpu, and in advanced warfare while loading maps 62c for the package to.

Feel the water block & tubing all the way along from the water block to the rad & back from the rad to the block - while it may be a little warmer near the CPU block it shouldn't be excessively so ,the return tube should be significantly cooler than the outlet one.
It should be a fairly uniform temp all over though.

This whole problem stinks of a faulty pump to me mate in all honesty.

Next time you test use amd overdrive thermal margin.

At 3.7ghz on prime I would honestly expect a thermal margin of a clear 20c+ at least - your temps are absolutely 100% not normal.

I mentioned about this 4 hours ago 😉

If you mount cooler correctly this can be faulty Corsair h55.
About FX max temps 62C for Cores , 72C for Package.

Hi man thanks for helping me like this. I felt the tubes and one is not hot wich i am guessing is the cool water to the cpu. and the other one is realy hot. So to me it seems like nothing is wrong but i could still be wrong.
Also i have amd overdrive and the temps on that are like 5 c higher then the cpu temp is showing in hw monitor. Right now at this moment i just started my pc and went to this site to respond. My cpu temp is 42c in hw monitor . the package is 26c and in amd overdrive all the cores thermal margin are jumping from 42c to 46c all the time. when i run the overdrive stresstest they go to 18c on the thermal margin realy fast and is still going down its on 13c thernal margin after 3 minutes.

Edit : I did the overdrive test for 12 minutes. The cpu temp was 72c in and package temp 60c in hwmonitor. And the thermal Margin in amd overdrive was 10c. hope this is some usefull information.

What brand model you use thermal compound ? * maybe I miss this info but please tell me this 😉

Artic silver 5. I also put my fx 8320 factory cooler on my little brother his athlon cpu. with artic silver 5 and he idles 40 c in games on load 😱 dont know if there is alot of difference in the cpu thermals of the athlon and fx8320 . + his room is always way hotter then mine.

 

[DeathRabit]

What method you use to apply thermal past on CPU, credit card, line or green pea method ?
Because your CPU temps look like poor heat transfer from CPU to CPU cooler.

I used the pea method

I just did the overdrive stress test for 12 minutes. The cpu temp was 72c in and package temp 60c in hwmonitor. And the thermal Margin in amd overdrive was 10c. Thermal margin in amd overdrive was to 18c in a few seconds after starting the test. and it dropped from 18 to 10 in the next minutes. However the prime95 test does this even faster. wich i have not tried with the thermal margin temps yet.

 

[DeathRabit]

FX-8350 Core is really big http://www.xtremesystems.org/forums/attachment.php?attachmentid=132018&d=1407413194
And pea method sometimes not cover entire core area, every core have this same temperature ? * thermal margin
I more comfortable wit credit card method.

Yes every core has the same thermal margin. And it said on artic silver 5 website to use a peamethod with fx processors. so thats why i used that.
