IntelBurnTest - The new stress-testing program

[LoneWolf]

Great program guys, thanks!

One question --is this an ideal program for burn-in testing mainboards too (not just CPU/RAM), or is there an alternative I should check out?

[The-Fox]

It's only using 50% CPU on my i7 (HT enabled) - all 8 threads show activity but none are peaking out. Most of my (12GB) of RAM is being used, I selected option 1, Maximum stress, and am running 64-bit version on Vista 64. Any suggestions?

Having the same issue right now.
Vista64Bit, Linpack only uses 50% CPU with HT on.
I can swear it was using 100% at lower CPU clocks, at about 3800 Mhz, but at 4200 Mhz it started using only 50%.
I don't recall if the CPU settings were identical though.

Any known fix/workaround ?

I still can't run "Maximum stress" but the rest looks ok.

Cool program, thanks!!
Failed the last one, needed 2.15v on the mem to pass.

Well that was depressing...I finally got my E3110 (E8400) to get through 5 passes but it required adjusting a bunch of voltages and dropping it to 3.66Ghz.
I'm starting to think I might be at least partially limited by my cooling since my CPU was bouncing off 93C even after I turned up the fan and lowered the clock speeds...I wasn't running RealTemp before when testing at 3.8 (it crashed pretty fast) so I can only assume that it was dangerously close to TJ Max. Guess I might have to finally upgrade my old Zalman CNPS9500

But either way great tool, definitely a lot faster than Prime for bringing my system to it's knees.

As sad as it sounds that's exactly why I love it. My new testing regime is IBT "Custom" w/ 10 passes minimum, Prime95 "blend" overnight and if I'm still concerned about memory Memtest86+ overnight.

Great stability tester. 25 loops is more than enough for everything I need And it takes just 30 minutes

[WaterFlex]

50 loops are needed

[davidk21770]

50 loops are needed

Beyond 15 is just wasted. Switch to something that tests memory and NB at that point: prime95 blend/OCCT mix

[WaterFlex]

I use 200 loops to make sure my CPU is absolutely stable often When I am sleeping, my CPU does a huge-hard-imba work

[radaja]

man waterflex i would hate to be your cpu.work work work work....... just wondering does it ever get a break?

[WaterFlex]

Nope I noticed:
When my pc just download smth during the whole night, the room temperature is 20-21 degrees. But there is a winter in my country, -10 degrees outdoors, so I am a little cold.
So I use CPU+Termochill+Linpack to keep up my room temp at 23-24

I saw you saying that 15Loops are ok, taht is what i made to test my system.

Now i saw you too saying to test with prime95/OCCT.

Why ?

Is IBT not stressing the Ram too ?

Do i need to test my Ram with one of the mentioned programs too after passing 15 Loops ?

If yes which program must i use and what am i looking exactly ?
The Ram or NB ?

Personally I don't think 15 IBT passes is enough.

I always test mine with a minimum of 30 runs of IBT coupled with overnight passes of Prime95 small fft and blend (min 8 hours) for a 24/7 computer.

[GrossmeisterB]

How many loops are really "OK" now?? Does IBT test RAM, too? Taskmanager shows that it is using a lot of memory, seems like it's all of my free memory!
So what's better to test stability? IBT oder P95? Or can I use OCCT?? I don't really trust P95, it often gives me errors, also if IBT and OCCT works "forever" without crashes or errors!!

IBT doesn`t stress RAM at all. Also it doesnt stress NB. IBT stresses CPU only.
If you want to test your RAM<-->NB you should use Windows MemTest 3.8. This small program stresses RAM and NB like hell. And finally, use OCCT/Prime to stress the whole system. Just let it run for 8 hours while you are sleeping.

Really? OK, so I will try MemTest...because P95 "small FFTs" is stable (just like IBT), but P95 custom isn't...

[jess1313]

Thanks for the program.

I will concur with the others, this is terrifying to run though. 13c Hotter than P95 for me.

I didn't read the whole thread, so my apologies if this has already been addressed, but I do wonder about the safety of repeatedly shocking the core from 60c to 42c between tests. I goes up sooooo fast. Could this eventually lead to cracks in the die, or are CPUs simply designed to withstand this kind of torture?

[GrossmeisterB]

You don't have to worry about those increases!! It won't hurt your CPU!!

[WaterFlex]

Any news?

I have a small problem while launching Memtest 3.8. I launch 2 sessions when i start the test my computer starts not responding and Memtest tries to fill the swap file of the system too. I wanted to stop Memtest but there was no way to stop the 2 sessions,only a forced reboot helped.
Any suggestions ?

awesome program for overclockers who really care about stability of their system. i love it

[Oats]

I started using this when I got my E8400, it works great for testing the CPU but temps start to scare me when they get into the 70s. And you need something else to test the memeory/nb, I passed 30 rounds of ITB and prime blend failed instantly until I lowered the fsb.

[BababooeyHTJ]

Wow, I honestly found prime to be a better test on my dual. I recently upgraded to a q9650 and WOW. I ran prime for a hours with no errors. I went and loaded this up and BAM BSOD. I had to bump up my VCC and now I seem to be stable (Im in the middle of a 40 run test). This test is no joke.

[Falkentyne]

If prime is stable, you dont need to increase your vcore. It's unnecessary if everything is stable under prime and all other applications, but not under linpack. There isn't a thing that can bring your computer down if all your other programs work fine.

I'm rock solid under prime@4 ghz and 1.3625v (1.352v load), but linpack needs 1.375v (1.360-1.368v load) for stability. That's only because linpack heats my CPU up to around 69-71C. Nothing in the world can heat the CPU that high..do you see the point? But I would never need to run my qx9650 @ 1.375v @ 4 ghz with my TRUE (my tuniq couldnt handle the heat) as nothing would need this vcore except linpack. So 1.3625v is fine for me. (I actually use 1.35v if im not using a heavy stress game).

To keep your cpu running healthy, lower it back to what you needed for prime. But you can rest assured that when you are linpack stable, that cpu will never crash under any circumstances (as long as your RAM/northbridge is stable).

Remember the reason you crash is because linpack heated up your CPU higher than what Prime could do. No program can cause that type of stress...
