    It did not. I was getting a random BSOD while surfing the web and moving files from one drive to another.

    I eventually found that the BSODs were caused by Voltage Offset setting it self. By switching back to manual Voltage setting, the BSODs were gone.

    I updated my LinX to the latest linpack, and if I just place linpack_xeon32.exe and linpack_xeon64.exe in the folder it complains that a DLL is missing (libiomp5md.dll). If I place this DLL in the folder linpack errors out as follows, this is at stock speeds btw:

    Same issue.

    You can still run Linpack from the command line if you wanna heat your Haswell

    Download Linpack from Intel:
    http://software.intel.com/en-us/arti...npack-download

    Unpack and go to folder (this is for version 11.0.5.009):
    w_lpk_p_11.0.5.009\linpack_11.0.5\benchmarks\linpa ck

    Edit lininput_xeon64 file, for example, for 4GB RAM the problem size is 23118 (you can check Linx which problem size you wish to run):
    Code:
    Sample Intel(R) Optimized LINPACK Benchmark data file (lininput_xeon64)
    Intel(R) Optimized LINPACK Benchmark data
    1                        # number of tests
    23118 # problem sizes
    23118 # leading dimensions
    30  # times to run a test
    4  # alignment values (in KBytes)
    Run runme_xeon64.bat

    Results will be in win_xeon64.txt file

    That's it

    I tried several different version combinations of Linx and the latest intel linpack library but I kept getting out of memory errors, even with something absurd like 32 megabytes selected. Finally a combination worked.

    I used this linx version from post 838 in this thread: http://www.mediafire.com/?7w8xpkd233i85f8

    And then I copy pasted the xeon64.exe ONLY from the latest linpack library (as at time of writing) into the folder that contains linx.exe

    for reference, with approx. 12 GB selected for memory, I'm getting ~200 gflops on my 4770K with HT disabled and 4.2 GHz. With HT it drops down to ~165.

    For AMD users who might face with the Non-Loading issue with the latest Linpack v11.0.1.005,
    I have come up with a patch to resolve this problem.

    LinX 32-bit


    LinX 32-bit log


    LinX 64-bit


    LinX 64-bit log


    For the AMD patch I changed the hex byte 75H (JNE) to EBH (JMP), ie I forced the code
    to jump straight to the Linpack Math library routine regardless of the CPU type whether
    it's Intel or AMD. Nice, right?

    Some hash values and short DisAssembly explanation to the original and patched files,
    32 and 64 bit.

    linpack_xeon64.exe (Intel CPU only)
    CRC-32: ee84f31b
    ---MD5: ea2c1ed5d9ea12a3df2e47ee7666ab12
    -SHA-1: a4f9effd7b23afc85b8b3858ff44c9764c580f8c

    00046C 85 C0 Test EAX, EAX......................; Not Zero = Intel, Zero = AMD
    00046E 75 2B JNE Some Memory Address.....; Intel, so go to Math Routine

    linpack_xeon64.exe (Patched, Both Intel and AMD)
    CRC-32: 3f167792
    ---MD5: 4032d811603594a0785c7bb1dd67bf7b
    -SHA-1: 8a7f62581846bd33be45161f09738f348e07882c

    00046C 85 C0 Test EAX, EAX......................; Not Zero = Intel, Zero = AMD
    00046E EB 2B JMP Some Memory Address.....; Don't care just go to Math Routine

    linpack_xeon32.exe (Intel CPU only)
    CRC-32: c184babb
    ---MD5: ab203fd622c162782933591e273cc880
    -SHA-1: 6a0f78d647ff3fc60a8972939326b9048af283d4

    001038 85 C0 Test EAX, EAX......................; Not Zero = Intel, Zero = AMD
    00103A 75 2B JNE Some Memory Address.....; Intel, so go to Math Routine

    linpack_xeon32.exe (Patched, Both Intel and AMD)
    CRC-32: e84cd5c4
    ---MD5: 60882e2d5024364fab26910daa815b4b

    00103A EB 2B JMP Some Memory Address.....; Don't care just go to Math Routine

    The short DisAssembly explanation might be wrong or inaccurate but I think you get
    the general idea.

    Credit to AgentGOD (IBT creator) who I think to come up with this brilliant idea and
    be the first person to do this patch years ago. ;-)

    For AMD users who are creative enough you can use this latest Math library with IBT v2.54
    too by copying and renaming the appropriate files. Don't forget to copy the Intel OMP
    Runtime Library (libiomp5md.dll), 32 and 64 bit version to the appropriate folder also.

    Datafilehost :
    Code:
    http://www.datafilehost.com/download-d5b49d25.html

    Thanks a lot! What software did you use to edit the exe?

    Hey everyone. It's been a while.
    I was told that LinX is having trouble coping with latest Linpacks, so I tried to fix it.
    I also uploaded the source to GitHub in case I decide to take another leave. It's ugly as hell tho.
    Anyhow, here you go, v0.6.5. Linpack binaries themselves haven't been patched for AMD compatibility, but I see that this problem has already been solved here.

    Updated 1st post as it appears that it actually works not only on my Windows VM.
