PC crashing in Prime95

[phoon]

I've been troubleshooting this PC for days.

 

It has an i5-6600 w/ stock cooler. I'm testing out both the CPU and RAM w/ prime95 and temps hit 100C and CPU throttles (26C on idle) sometimes it crashes before I can stop the prime95 test. Swapped out the RAM but Its doing the same thing.

 

Is it normal for temps to 100C on stock cooler.

 

It starts hitting these these temps on test 2 in prime95,

 

Doesn't even blue screen anymore just shuts off.

And you're surprised it shuts off? Would you prefer the CPU taking serious damage? I mean, what do you expect from the stock cooler? Throwing repeatedly Prime95 at a system that struggles to stay cool and stable is not really sensible. The Tjunction of that generation of desktop chips is 100°C. Idle temps are mostly irrelevant. 

 

If you suspect some defect you need to fix the thermal issues first before torture testing it with Prime95.

Why are you running prime95 with a stock cooler? Your hitting the thermal max for the CPU which will shut down the PC.

no. try to repaste it and clean the fans

The old Intel stock cooler is terrible, as in literally garbage.

Is that so alright I'll retry with an AIO

Any program I can use to test out the system, something other than prime95?

Well hold on there, it's not just one or the other.
- Hyper 212
- NH-D15

These have better performance than most AIOs

 

And for reference Prime95 is literally a torture test, not a realistic test of daily use

Superposition is free but it's mostly gpu heavy

Depends on what you want to test. If it's memory you're trying to test: MemTest86. Cinebench is a viable overall test scenario for CPU and memory. Furmark is a torture test for the GPU, 3dMark is a viable overall performance test.

 

You have not specified an error to make any recommendations.

Corsair H100i v2?

What is the issue with the system? You're about to just throw money at a system to fix an unspecified error.

It just crashes on CSGO.

 

I thought Prime95 was like any other stress test but I've learned today that it's what you can a torture test

I have an H110i

Can confirm any NH-D15 model will give this thing a run for it's money (I'm using a 3900x and the D15 is still a solid consideration, think about that)

I already have it but I swapped it out because I was afraid the pump would soon die out on me

Oh you don't need to worry about that. The pumps run at a static speed regardless of the water temp and they're rated for at least 45 c

All the cooling is done on the radiator. imo throw that sucker on and you'll probably fix the high temps issue

No, 100C is not normal...it is throttling and probably shutting off to prevent itself from burning up. 

 

Prime95 is probably crashing because of this...even if it's something else causing this, the thermal issue is something you will need to fix. Intel stock coolers are crap, but should be sufficient. I'd remove the cooler, clean the CPU with isopropyl alcohol and reapply quality thermal paste.

So what are the temps during CSGO gaming sessions (CPU, GPU, system)? Use HWInfo64 and have it monitor the system in the background. Make it write a CSV log.

 

The Intel stock cooler is a bad joke for anything else then light office use.

 

If your CPU reachs mid to high 90s then you definitely need a new cooler asap and you have probably found the cause of your issues. If it isn't going over 90°C then you have a different issue. Make sure memory is fine with memtest86 (will boot from a USB stick an test for a while).

Why did you think that? Any symptoms in that regard?

This. The important part here is you don't do anything with the stock cooler after removing it

that is literally stock cooler, atleast AMD's stock coolers (wraith prism) performance. that is nowhere close AIOs.

I just need to make sure that the memory isn't the issue here.

 

Do you think it's fine to run memtest86 on the stock cooler or should I install the AIO?

Perfectly fine.

Well fuck beside a 6th gen intel stock cooler it might as well be

 

 

You are hilariously correct

i did not know i was that close lol

Does sound like multiple layers here. Throttling might be expected as described, but crashes and shutdowns are not. What is the rest of the system spec?

 

Check the cooler is mounted correctly. The stock cooler has several split pins that should go through the mobo. Especially if the cooler has been used before, it is easy to bend one of the retaining bits so it catches on the wrong side of the mobo, causing an uneven fit.

 

Is there plenty of airflow around the cooler? Try running with the case lid off and see if that makes a big difference. If it does, look at case airflow.

 

Assuming we get past the cooling, it would be interesting what errors are found by prime95. Depending on the FFT size it failed on, we can deduce where it is more likely to have happened. Generally, smaller FFTs stress the core. Bigger FFTs stress the IMC and ram more.
