Intel Burn Test

I've just recently finished assembling my new build and was doing some tests on it last night. This is my first overclock so I very well might be doing something wrong but for some reason Intel Burn Test just fails immediately out of the gate (2nd pass) with stock settings. I'm using RealTemp and at stock settings nothing gets above mid fifties on IBT or Prime95. After playing around in Prime95 I found 4.5 GHz ran for 2 hours without errors with an increase in voltage of about 0.5. I'm running the same test while I'm at work today to see if it's still going when I get home but I'm still confused about IBT failing with stock settings?? Could it be my memory?

I'm using an H100 for cooling with stock fans.
 
Temps according to RealTemp max out at about 63 and usually hover in the mid fifties under OC 4.5 with voltage at 1.15.

I just don't understand why it's failing so fast at stock settings but Prime95 seems okay for hours on end. I know IBT is supposed to compress Prime95 results into a fraction of the time but I'm not even getting past second pass as opposed to 2 hours of stress under Prime95
 
Make sure you update your linpack libraries for IBT.
Google "Intel math kernel library download"

Get the release that's correct for your system(32/64 bit), then just overwrite the files in your IBT folder with the new ones.

Lastly, make sure you select the largest amount of memory possible. Doing a 1GB test on a 4GB system doesn't prove stability.
 
Thanks, that sounds like it could definitely contribute to the problem I'm having. I'll try that first thing when I get home.
 
Figured this list might be helpful to you also.

Overclocking BSOD code list for SB/IB:
0x124 = add/remove vcore or QPI/VTT voltage (usually Vcore, once it was QPI/VTT)
0x101 = add more vcore
0x50 = RAM timings/Frequency add DDR3 voltage or add QPI/VTT
0x1E = add more vcore
0x3B = add more vcore
0xD1 = add QPI/VTT voltage
“0x9C = QPI/VTT most likely, but increasing vcore has helped in some instances”
0X109 = add DDR3 voltage
0x0A = add QPI/VTT voltage
 
Is the system stable if it passes normal on like 25 runs but fail on Maximun?

Well, it`s not 100% stable then. However, IBT loads CPU/Memory much more than any application you use every day is likely to, so your current overclock should be pretty stable anyway. I remember once I had an OC`ed system which would fail IBT, but it was perfectly stable with all real world applications like games or heavy video encoders.
 
I had the same problem with IBT - increasing memory voltage a touch fixed it right up.
 
Yes, sorry it took me so long to post but this weekend was busy. After I upped the voltage to 1.5 everything performed fantastically. I'm now stable at 4.5 GHz at about 1.2 volts. Thanks for the help guys!
 
I would ignore the IBT. I've found the prime95 works the best. I've had stability issues while passing the LinX, IBT, but all the issues were gone once I passed the prime blend. Try to run a custom test with the 1792 FFT size. Should determine the stability within the 30min. Once you pass that, you can do a prime blend.

Anyone who thinks prime is a good testing program fails at overclocking. It doesn't test any real level of stability on modern CPU's. If you had stability problems in LinX and IBT after updating your linpack binaries, your overclock was unstable. Pure and simple.
 
The last few versions of Prime has issues with stability so at this point it's not really a great tool for stability.

Looks like they may have finally nailed it down -

Prime95v.27.7 Build 1 (32/64-bit)
ftp://mersenne.org/gimps/p95v277.zip
ftp://mersenne.org/gimps/p64v277.zip

- Torture test on small FFTs gets round off errors or crashes after a while. In very rare cases, regular tests could crash or raise a round off error. Fixed in version 27.7.
- Multithreaded FFTs could deadlock. Fixed in version 27.7.

But they thought they had it fixed in the last version so who knows....

Prime95v.27.6 Build 4 (32/64-bit)
ftp://mersenne.org/gimps/p95v276.zip
ftp://mersenne.org/gimps/p64v276.zip

- Mprime -v does not print out the build number. Fixed in version 27.6 build 4.
- Torture test on small FFTs gets round off errors or crashes after a while. Fixed in version 27.6 build 4
 
EDIT: Well my reading comprehension is not as good as i thought it was...I see that you do not pass even at stock settings. Not to sure about that but i would think that if you are not able to pass IBT with stock settings then i would think something may be wrong with your hardware. Have you tried MEMtest to see if your memory is ok.
