I am just saying,you need to remember,unstability is not predictable,you can't say "ok I ran prime for 3 hours and now every game need to work for atleast 3 hours too not a minute less"
If you think this is not correct,then indeed you are wrong
There you are again telling me that what I'm saying is wrong. Never once have I ever told you that what your saying is wrong. Your epeen must be showing pretty hard, pulling out experience and what not. You don't know me, you don't know anything about me or my experience in overclocking at all but yet your so quick to tell me that I'm wrong because my logic does not match yours. Look my friend, this is getting futile. You stick to your and I'll stick to mine. 3hrs stress test is good enough for me. Never had a had a rig bsod during anything after I've set the overclock. If your trying to belittle my knowledge in this then your wasting your time. Your words do not effect my mind, my money, or my overclocking ability so I really, truly don't care what you have to say.

10 Runs of LinX is good enough for me. The only thing that even uses my CPU to max is Video convention. I could tell my CPU was not stable just buy doing my everyday stuff.

Sometimes I wonder if the so called "Windows rot" is caused by people with unstable overclocks on their computer.

72hours what??
holy smoke people are crazy..
if is stable then .. i call you professional geek.. no offence!

i did for 12hours over night

This is really ironic considering the replies in this thread. I just jumped on that deal from directron for 6GB of ram for $25 shipped to replace my 3GB.

I set the ram to my previous settings and tightened the timings a bit, booted into windows and ran four instances of HCI memory test as a quick check to see if each stick was working. Each instance passed 300% without an error.

Then I fired up IBT, set it to maximum and let it run 30 passes, which took almost two hours. "Congratulations, you passed without errors! your PC is stable!!!!"

Then I fired up a custom Prime95 blend to use most of my new 6GB and I get a rounding error within TEN MINUTES. Booted back into the bios, bumped the ram voltage one tick and its currently running well passed the spot where it had an error.

12 hours of Prime95 blend is absolutely needed if you want a somewhat stable PC.

In your example,you play games a few hours a day.So you test your oc also few hours a day.But that's wrong way to do it. Why ? Because system stability has nothing to do with how long you play your games.So you test prime95 for 3 hours and it passes. You conclude your system is stable,but yet it is not. You continue to use your pc,and one day it can crash/bsod/restart only 5 or 10 or whatever random number of minutes after you start your game
just because system is stable on prime for lets say 3 hours,it does not mean it will be always stable for 3 hours in games or other software
So even if you want to play games only 3 hours,you must run prime ( or other testing software ) for a lot longer to see if you system is stable or not
How long you play games or use other software has nothing to do with how long you should run prime.System instability is unpredictable.3 hour of prime stable can crash within 5 minutes next time you run prime again.Or in games or any other software
you just said yourself that "system instability is unpredictable" so by that logic even if you ran prime for 3 days you could still crash. Therefore theres no point to running prime that long because it will still crash

Stability tests are so overrated. Really just another epeen show. Run IBT 10 times and use your computer normally. If you get instability, adjust accordingly.

72 hours of Prime, jeez...
post #59 of 63
If ive just built a new rig I dont want to stress test it for 24hrs, I want to use and enjoy it. So I do 50 runs of Intel burn test with all RAM tested which takes about 2.5hrs then I spend the rest of the day ENJOYING useing my machine.

Ive never had a BSOD from testing that way, Heck I've never had a BSOD from just doing 5 runs.

Prime95 is too old for these new processors. With load line calibration enabled my Vcore jumps up 1.52v while stressing with Prime. With Intel burn test it shoots up to 1.56v showing that its putting more stress on the overclock.

imo.. as long as you compartmentalize your overclocks, that is you keep everything else at stock and focus on one component... ex. only cpu, then an hour should be enough with something very cpu intensive like large ffts, or LinX.

Then overclock your ram after wards with your known stable cpu clock... run super pi 32m, and hci mem test (300 percent pass is good enough for me) and tweak your vtt/qpi as needed maybe even vdimm and your done.

All in all it does not take 12 hours

This method nets me very stable systems... don't bsod at all unless i'm tweaking blck for ln2 or max clocking my ram
