    Prime95 Vs. IntelBurnTest

    Hello friends,
    I have recently started with the studies of an Overclocking. I want to know that which is the good utility for an overclocking, is it Prime95 or the IntelBurnTest..?? Since, I am not having much knowledge about it, I expect some useful information about that utilities from you members. So tell me something about the Prime95 Vs. IntelBurnTest.!! Hope that someone over there might be interested in sorting out my doubt.

    Prime95 : The software commonly used as a test of stability, Prime95 has been updated to version 25.6. If you are overclocking and just want to test the stability of your setup, so GO! The changelog of this version is not great since the bug corrected main problem relates to a function at the SSE2 factorization above 2 ^ 64.
    In my own experience, I Used Prime95 on my Q6600 with Small FFTs, Which Showed That It Was stable for 10 hours overnight at the current voltage. However, running Linpack with the most available memory I Had (I Have 64-bit XP, so I see all 4 GB of my RAM), it Indicated Instability. I Had to raise the voltage up a couple of notches To Get Fully it stable. This will Ensure me that it's now at least 24 hours Prime95 stable, if Not 100% stable.

    The classic Prime 95, but now with support for dual core, this program performs multiple mathematical calculations that require high precision, comparing the results obtained with previous findings that already have in your database, and if there is any inconsistency, the program informs you and shows the error. For this you need to activate the option: Round Off Checking, on the progress. With different types of test, where you can Stress, either the FPU, the maximum heat generation, or a combination of CPU / Memory. This test is very curious, being in most cases, show instabilities in the first 5 minutes, but some cases may show errors up to 6-18 hours of execution, the ideal to know that your system is 100% stable , is 24 hours.

    You can also go for the OCCT. An excellent program to test the stability of our PC, among other things I love because it is very robust, very fast, and extremely sensitive to the stability (Especially the new version 2.0), also at the end of the test, with an integrated monitoring system, although it remains fully compatible with Everest, SpeedFan or some more programs, sends some interesting graphics, with readings of voltages, and temperatures. It is also worth noting its intuitive interface and support for multiple cores and platforms. Already in practical use, if your PC is not completely stable, in 5-10 minutes, I detected. The default test is 60min, being sufficient in most cases, now if you are unsure of complete stability are ideally 6-12 hours.

    We use these programs because they are most stressed and better use instructions to the microprocessor. Programs like "Prime95" we can have 48 hours you can get stable, but with 3 hours of "SP2004" or 5 past the "IntelBurn Test" we jump with errors. Also the temperature difference between these programs FULL I use and the other is around 10 ° C-20 º C, this is not my invention is simply because they make full use of all instructions of the microprocessor. This is simply to rule that any application or applications running, even CPU-consuming, never stress as a test made for the purpose. With this we know for certain that this temperature is never reached.

    The following are the steps for using the utilities :
    • It is recommended to use a 64bit system to achieve even more accurate and reliable. On 32bit system, due to a limitation of Windows, it is not possible to test more than 2GB of ram.
    • Used the maximum RAM possible (IntelBurnTest the fact alone, the more memory used, the more reliable the result will be).
    • Choose the number of times the test will be performed (5 registered, 10 have more reliable results, not necessary 10 +).
    • Run the test. The window should display some things, similar to :
      Code:
      Size LDA Align. Time (s) GFlops Residual Residual (norm) 
      10000 10000 15979 4 41.7337 1.012665e-010 3.570760e-002 
      10000 10000 15119 4 44.1087 1.012665e-010 3.570760e-002 
      10000 10000 15216 4 43.8254 1.012665e-010 3.570760e-002
    • The above values indicate that the test was completed successfully without instability, but, conversely, values below indicate instability of the system.

    The instability can not necessarily at the beginning of the test. This can happen in the middle at the end, etc.
