I ran prime95 for 13 hours, 17 minutes without any errors or warnings.

Then, just the other day, I ran it again and had worker #2 fail after 5 hours, 4 minutes.

This build is barely 3 months old. What is going on? I'm told prime95 should never crash. Why do I keep getting mixed results?

Thank you for your help.

Welcome to the forums.

OK, the system is testing as unstable. Step 1 is to test the system under default settings, we usually use Prime95 to test the stability of overclocked systems. If you are failing Prime95 under default settings, then maybe start looking into the cooling situation, what your case/CPU temperatures are...

Hey, thanks for you message. It's good to be here.

I used prime95 under default settings. My CPU temperatures are around 34 degrees Celsius, I'm guessing it could be a little cooler or the air flow isn't ideal. Would the application of the thermal coolant have anything to do with it? I thought I put it on correctly, but I guess I'll check again...

Also, I just heard about motherboard monitor, I figured I'd look into that as well.

Do you know if the Hyper 212 coolant fan is sufficient for my system? My chasis has multiple fans as well, it's a corsair obsidian 750D, I figured in total it would all be enough, but now am wondering if I should invest in something more thorough.

Any other thoughts?

We typically say that 2hrs of Prime is stable for most tasks.

Are you having crashes in your daily use? If no, then just leave it alone.

That would be a separate topic when it comes to how high you can overclock. For now, you should be stable at default settings with your default setup.

Although a two hour pass of Prime95 is an indication of some stability, the correct time frame for indication of full stability is 12-24 hours of Prime95 Torture Test. Really 24 hours but people don't want to tie up their rig for a full day, so at least overnight 12 hours should pass before you can feel confident to fully stress the overclocked system...

You should not be failing at default values.

I assume Memtest ran from startup media (not Windows) has been done? Here's a decent temperature monitor: http://www.techpowerup.com/realtemp/

And here's Super Pi, which is a quicker indicator of (in)stability:

Thanks for the links.

The first time I did the test, it was for 13 hours at default settings, so I felt assured after that.

Then, just the other day I was on youtube and it started making some erratic humming noises, so I had a look at performances on task manager and it showed a lot of random spikes going all the way up the top. I wasn't doing anything stressful to the system, just simple navigation.

So, I ran prime95 again, that's when the worker crashed after 5 hours. Hence, my confusion.

As for Memtest, I ran it soon afterwards and got 5 successful passes, no errors.

I can't say accurately whether or not I've been having daily crashes, I got all worked up when I saw that prime95 had failed. My browser is the latest IE, I've had that stop responding a few times.

Just the other day, I could hear my fans going on and off sporatically, so I checked the perfomances on talk manager and saw a bunch of random spikes topping the charts. I wasn't stressing the system at all, it was simple net navigation. That led me to run prime 95 again, then I encountered the failed worker.

The new IE is not that great, I've had it just lock down on perfectly stable systems.

Did you think that might have just been something running in the background on the computer, not failing hardware?

 

[GaldedRaw]

Too me, hearing weird noises like that may be an electrical problem. Is everything set properly? Maybe some wires got lose.

 

[Mandrake4565]

Try this, download HWmonitor and Cpu-Z. Then open HWmonitor and run prime blend 20 minutes. Post back screen shots of Hwmonitor and the following tabs in Cpu-Z, Cpu, Spd and memory. It will give us a look under the hood so to speak. Here's how to host the pictures to the forum.

Good to know I'm not the only one having some issues with the new IE. It could've been something in the background, I didn't think it wouldn't be that enough stress to cause a program to crash.

Good call. I'm going to double check the wiring just in case.

Just as I was getting ready to post those, I realized I hadn't done the tests after running prime. I'm taking care of that right now. Should have it posted in about 20mins.

IE really bites, go back to 8 or nine, still better is firefox.

Ok, here are the results for HWMonitor and CPU-Z after about a 25min run on prime95:

Yeah, I've been using IE forever. I tried Firefox, but it start bugging on me, so I switched back. How about Chrome?

 

[Mandrake4565]

I don't see anything that stands out in the screen shots. Maybe try pulling out 2 sticks of ram and see if the issue persists. Not say the ram is bad but maybe the IMC is struggling to run all 4?

Would it not be able to handle all 4? I thought I matched everything correctly when making the build. And the motherboard's supposed to be able to support up to 8 sticks, I never figured I was anywhere close to utilizing its full capability with just 4.
