Is Prime95 safe?

post #1 of 8
Thread Starter 
According to my crash dumps, my CPU might be causing BSODs that I have been getting about once a month ever since I built this PC in July. I am really new to PC's and was wondering if running Prime95, as I was suggested to elsewhere, is safe. As in, even if it doesn't get too hot, will running it reduce the lifespan of the CPU? I don't want to run it, find out my CPU is fine, and then end up regretting running it (my severe OCD is the one to thank here that makes me feel this regret, even if the effects are negligible). Anyways, any input is appreciated. Thanks.

Nope. It cannot stress the cpu over 100%, which is absolutely fine.

Itll get hot tho. Check temps at all times by keeping a monitoring-program on top just to be safe smile.gif.

KK thanks, at what temp would you begin to worry with an i7-4770K? Would you just go buy its tj max?

Id say keep it under 90c.

And thats talking about peaks. The haswells have different levels of load, from time to time itll fidget itself up another 5-10c. So try to be stable at the low 80s tops to avoid peaking over 92c (which is what Ive decided is max since most start to throttle about thereabouts).

Thanks, one final thing though. Not sure which test to do to just focus on my CPU. Which do you think would be best?

Edit: also how long's it take? that is all!

Thats really up to you.

They all stress the **** out of your pc. If you want to look for what components are giving you the BSODs youd better just check for error codes or overclock one piece at a time.

I run for 1 cigarette smile.gif.

If it works I jump another 100mhz. And for stability I check for about 30 minutes and then just play games for a week or two. No BSODs = Stable.

Then read up on it and do it after smile.gif. Since its such a personalized process what with different benchmarks, settings, steps towards your goal, max values, max temps etc... nobody can really help you 100% of the way, youll need to read up.
