Is it necessary to stress test for hours? - Page 3

post #21 of 32
this has been discussed many times and its always interesting to see peoples opinions of it.


I suppose It's a preference thing, but I've had errors show up after 6+ hours of prime, and that error could have meant corruption in a file or miscalculating a render/protein fold. duckieho is right, though - nothing is perfect enough to calculate everything perfectly all the time.

The OP has an AMD system. If he overclocks the CPU/NB, IBT or LinX are useless.
I use to run P95-blend(version 25), for 8 hours, at least.

For me, stress testing is some what over rated. Except, for what I want my computer to do. The most stressful thing I do on my computer is play BC2. As long as I dont have any problems playing BC2 with my overclocks, I dont need to run any other testing.

My system will fail Prime95 and get errors in OCCT pretty quickly, but I have no problems in BC2. I am sure I can pass these tests by lowering my overclock or by raising voltages, but for now I am content right where I am.

Until I start having problems in BC2, I will leave everything alone. This is just me and I am sure others will disagree. To each their own.

So, passing stress tests, no, as long as my computer does what I want it to do.

This is a very good point. I ran prime for only 3 hours and it was fine. I have since gone through and played every game, used every program, and done my day to day activities without issue. Besides, prime has always given me BSOD within first hour of testing (usually first 30 minutes) if not stable.

If you can do everything you need to be doing with the rig w/o any issue, why stress test for hours on end?

Not required,

Shortens life of components

The only stability you need is running the most demanding application you use.

That app. is the best stress test 100% of the time and it is different for everyone,

I use prime 95 and LinX for testing different settings for quick results

hour on prime a 20 passes on Linx.

You can argue that you may error out after 12 hours ..... keep arguing as that is rediculous.

Who cares unless you plan on running your CPU at 100% load in real world apps for 12 hours ....

The point of stress testing is to gain a certain confidence level of stability. If stress testing for a long time is perceived as unfruitful, why stress test at all? If you do not believe in stress testing for long periods of time, then why stress test for short periods of time?

I could just stress test for one second. One minute stress tests take too long.

Just do not stress test at all and have no idea how "stable" is your computer.
post #27 of 32
Its up to each individual IMO. I run IBT at max for 10-20 runs and thats it. I've never had a BSOD in normal computing (but my OC isn't very aggressive)....
post #28 of 32
I would honestly say, unless your messing with voltages you should be ok. I'd say the likelyhood of it crashing at 3.6mhz or so would be about the same as stock

I'll literally stress test for about 20 minutes, then consider my system as stable as can be.

Why? because:

1.Continued stress testing will gradually make my temps increase, bringing on instability and an inevitable BSOD. 20 minutes is usually as much as i can get out of it before it reaches dangerous temps.

2. It's always been sufficient enough, i've never experienced a BSOD unless it was triggered by high temps.

I've always struggled to keep temperatures under control on Umbra. Even after new fans, additional rads, and new blocks. QX6700's just run extremely hot. But they can take it.

I also agree with the gaming comment on the first page. Prime would put my 3.9mhz oc (on air) at 59c. However I gamed for 4+ hours on black ops with cpu id in the open. When i was done gaming the max temp reached was 50c. I think it has alot to do with what your doing. I've since went back to 3.6 since the only thing that improve was my windows score, nothing noticable enought to subject the cpu to that lvl other than putting it there. However i will probably see how high I can get it before it bsod's anyway because the price i paid for my 955 is cheaper than what the 965's are going for now lolz
