Intel Burn Test + Prime95 = Error?

[ianmills]

I'm troubleshooting my system. I seem to have got it so it can run Prime95 without errors and IntelBurnTest without errors when I run them separately, but when I run them simultaneously IntelBurnTest always fails on the second pass (regardless of any bios settings I make).

Can anybody run IntelBurnTest and Prime95 simultaneously without errors?

Thanks!


edit: I have an i7 socket 1366 system

Does it do this when you run your system at stock everything?

From Dualist, the author of LinX, like IBT, Intel Linpack based with a different GUI.

Yep stock settings. I have also tried running things lower than stock...
MadScientist, I'm not sure how your post is related to the original question...?

It would be awesome if somebody with a stable system could run prime95 and intelburntest simultaneously and tell me if it works for them

what is the benefit of running them both at once

 

[ianmills]

Either my motherboard or RAM is bad. My store warranty is almost out. If I don't RMA either soon I will have to ship them back to the manufacturer which is a major hassle....

If I can get the RAM stable at lower settings I will be pretty sure the RAM is the problem (yes I've tried memtest!)

Please I asked a very simple question. I will be so happy if someone can answer it

memtest86 v4.00?

have you also done the os Memory test? i think vista has this feature... 'memory diagnostic tool'

all i know is with DDR2 and a 775 system you need to set the ram at 1:1 to test its advertised speed. if you can get someone to confirm the proper divider for DDR3... it might very well be the same... i don't understand how it would be any different but i know for sure thats the correct way to test on a DDR2 775lga system... no other way is better/ 1:1

EDIT: what do you mean by lower settings - going from CL7 to CL6? test everything at its rated speed, voltages etc.

explain to me why your running both tests simultaneously?

Yes i can see why your getting errors.

Lemme make an analogy for you.. your trying to sprint, when your already sprinting.
which makes no sense in why your running both stress programs at the same time.

Please I asked a very simple question. I will be so happy if someone can answer it

Ummm.. no your asking a very weird question.
No one on this forum would think of running 2 stress programs at the same time.
(your not understanding the reason for the programs to begin with)

It just doesn't make sense when both can do 100% and what your asking for is 200%.

You need to manually allocate your resources to each program so each program takes up 50%

kinda what i was thinking not to mention the maxing out of the ram anyways with one program then the other wants all that ram again... unless one is running small ffts and the other is using the full ram.. ???

no its because he has all his cores already loaded.

Then add another program that loads up your cores on top of that.
(one of the programs will be starved of the cpu time needed, and then error)

He's asking for 200%

 

[BTRY B 529th FA BN]

yes, it doesn't make any sense to do that, i asked him why but am still hopeful on a good answer

Based on the overclocking stability thread from over a month ago, you should RMA your CPU.
If your CPU can't easily pass a stability test at stock settings you should RMA to prevent silent data corruption.
It shouldn't matter if you're running 2 or 10 of those programs at once. The fact is your CPU isn't stable.

did u miss me saying in the last 2 posts..

no..

he would need to manually allocate the resources to each stress program so they took 50% instead of 100%.

The moment one of the stress programs tried to pull a core which is being used by the other stress program, it will not be able to pull a value, and will ERROR.

Which is why i said your not understanding what and how these tests are.

No, Aigo, it doesn't work like that. It shouldn't error, the OS will sub-divide the CPU times so that each program would get half the slices that it would get if it were running all by itself. That's what a multi-tasking OS does.

Something is unstable in his config.

Larry run both.

See if it works.

Set Intel Burn on 100% memory.. run it first..
Then run Prime95.

 

[Gillbot]

I can run OCCT fine and Prime 95 fine, when I try to run both one or the other errors. Explain that?

QFT LOL.

Come on Aigo you're full of wisdom, but this one exploded.

OP,

There's no point in running two stress tests, one stress test already has the capability of occupying 100% of your cpu time. It's no cause for concern that two tests together are failing, because your system should NEVER run two processes that both occupy your CPU 100%, you are doing something that neither the hardware nor the software was designed to do. Windows was designed to split the resources among different processes that require a portion of processing power, not between processes that require 100%. If you are running a process that requires 100% you shouldn't be running anything else.

 

[Meghan54]

I think what most fail to realize with these stress testing programs is that, left to their own devices and settings, act like black holes in your computer.

They're not written like normal programs and will take and hold onto every shred of resources, computing power, memory, whatever until they're stopped and resist allocating any resource they're stressing to the point of crashing/locking up your computer.

But, if they did reallocate their resource needs at the drop of a hat, what good would the programs be for real stress testing?

 

[ianmills]

So what you guys are teasing me about (but never saying explicitly) is that my computer SHOULD fail if I run both prime95 and intelBurnTest simultaneously?

NO. false. untrue. The OS should properly delegate tasks to the CPU. It'll take longer to process each FFT, but there is no reason why they should fail. Unless of course prime and linpack are written to ignore OS intervention and somehow address cores and memory directly.

 

[nova2]

here's what i suggest you do.

if you play Crysis (or play it inside sandbox2) and concurrently run prime95 on all cores, and Crysis works (albeit with lower FPS but still playable for me)
and does not crash (after 30-60 mins) then I don't see any reason why you should bother to be concerned about your stability for gaming/etc.

good luck.

 

[aigomorla]

Ok.. then someone run both programs and have a screen shot of it going in 15 min.

Unless of course prime and linpack are written to ignore OS intervention and somehow address cores and memory directly.

I think Linpack is.. that's why.

 

[VirtualLarry]

Wow, this thread is full of fail.

I started Prime95, small FFTs, and then I started OCCT v3.1.0, running the "Auto (1h)" Linpack test. I also have SeventeenorBust running in the background on both CPU cores.

Nothing's crashed yet, LOL.

Btw, IntelBurnTest is buggy as fuck if you set it to 100% memory. In fact, every time I've tried that program, on every computer, when you set it to 100% memory it fails right away.

[Hyperlite]

i'll elaborate on this later. goodnight.

 

[MadScientist]

Doesn't this whole thread boil down to the the question: Why would you want to run both simultanoeusly?
