I was told that running multiple 8 hour tests does nothing in prime95 since its the same test, just wondering if I have been wasting cpu life all this time by doing multiple overnight tests. Also how long have I killed off my 3570k by running prime95 for over 400 hours? Temps are always under 75c Vcore is 1.280v. I say 300 hours beacuse it seems like I have been running it overnight alot to test stablity ( new bios fixed issues but changed my stabilty and Sp1/AVX changed stabilty aswell )

Also I plan on doing a 24 hour run while I am away this weekend but I need prime95 to terminate or stop after 24 hours if possible. thanks

Using Offsets aswell

That chip will be long obsolete by the time it gets close to dying.

Your chip will not degrade with 300 hours. If im honest, anything more then just a few hours is pointless in a way. Some people who prime for 24+ hours crash a few hours after playing a game.

I ran prime on my fx 6300 @ 4.6ghz for 1 hour without errors and has been stable 24/7 with the longest time running without rebooting being 36 hours with around half of that gaming.

If your system has managed to run 8 hours of prime then i suggest using the pc how you intend to use it and if its completely stable without any crashes i would not bother with prime.

One other suggestion though is to open WHEA (windows hardware event architechture) as this can show errors that prime95 does not show.

yea prime runs flawless its whea errors im on the look out for, I will probably do 1 24 hour run and be settled. The 300 hours were of prime95, that shouldn't have harmed it right?

I'll say 400 hours to be safe might be less or more, just scared all this testing will quickly degrade my chip. Running offsets and havign temps pretty low (under 65c in games ) helps life expectantancy right? What degrades more? Voltage or Heat?

Consider this, there are servers worldwide that are pegged to 100% CPU almost 24/7. How often do you hear of CPU failures?

A few Prime95 runs really does not concern me at all.

After 2-3years of my Q6600 running at around 80c 24/7 I had to bump the voltage up two notches (0.010v ish?), the horror!

Anyhow, to kill Prime95 while you are away for the weekend you could perhaps schedule a system shutdown.

400 hours won't hurt that chip. I'm temped to say it will outlive you, but I don't know anyone can say that for certain.

 

Temps and volts both hurt, but less so on Intel temp wise. I have heard of intel chips running 100% load 24/7 at 90C for over 5 years. I think you're ok.
