My pc crashed after 11 hours of testing with prime i am stable? - Page 5

post #41 of 66
11 hours is a long time. I doubt you'll even use it that long before shutting it off for the night or rebooting. Of course if you leave it on 24/7 doing stuff then bump vcore etc

The thing is if his system crashed after 11 hours, it could crash in 30 min next time he runs, or 6 hours or whatever. Just because it takes longer to crash does not make it necessarily more stable. I say it that way because obviously a crash within 10 minutes is more unstable. But once you get past about the second set of test, which takes about 20-30 min, its just a series of test that loop random commands at the cpu and memory over and over and a crash at 11 hours is no more stable then a crash at 1 hour, but you are close. And you are probably fine for games, but you never know, you may get a random crash one day. How stable you need to be is a different answer in everyone's opinion. It matters highly on what you need to be stable for. Playing games, surfing web, not needed to be 24hr P95 stable, Folding, very much so.

Normally I prefer IBT or LinX, since it's a much quicker and more efficient alternative to Prime95.

Passing just 4 hours of linpack you can pretty much be assured of stability to an extent.

These posts really summarize it. A CPU is in working order when it never faults. If it faults, it's not stable, and it's as simple as that. It may have no erred until after about eleven hours, but that's not the point. The point is, it erred. It's not stable. It may have taken eleven hours in that case, but that instability could show up any time. It is not stable, and that's the end of it.

I had what I called a "100% boringly stable" PC for over a year, maybe a year and a half. Back when I was messing with it, it did Prime 95 overnight (can't recall how many hours exactly). It never crashed in games, so I was stable... until a year and a half later, surprise, I had a crash/BSOD during The Sims 3, which ended up pointing to the CPU. I didn't know of Intel Burn Test when I was doing my testing, but someone recommended it, and it caught an instability after two runs (on the seventh pass). Degradation? Never stable all along? Small mix of both?

Either way, it was no longer in a state I could call stable. I bumped Vcore three notches (never again just one, that "right on the line" is risky business itself). Now, it's stable again.

A CPU is deemed stable simply when it's not proven to be unstable. You could run it for one hour or one thousand, it's stable unless/until it's unstable. I'd run some good stress tests for more than a hour, of course, but the point is, it didn't matter when it happened. Your CPU isn't consistent. It's unstable. I'd bump it up two notches and put it through Intel Bun Test, then Prime 95 over night again. If it passes then, I'd say you're good.

just because he ran it for 11 hours doesn't mean it error after 11 hours it mean it can error any time an hour or even 2 seconds, it chose to error after 11 hours just cause.

cdoublejj has a point.
If it crashed in 11 hours, it can crash next 5 min, next 20 hours anytime.
Just test int Linx or IBT its way better then Prime.

pretty stable is NOT stable. I always run 24hrs of prime95 before I even think about calling anything STABLE. Simple as this. if it crashes..its NOT stable. 11hrs is not enough at all. my personal sig rigg has endured 50hrs on a single prime95 run and was stable and never got above 60* C. on coustomers PCs when they ask for OCing i will do a 24hr prim495 run AND an intel BurnTest just to be sure.

Always simple solution. if it crashes..its not stable lol
