    Not sure for a 4700k didn't know they made such a beast. As for disabling HT and what temp, Vcore drop you get not sure. I think I tried to disable HT and saw 0 improvement but I was still learning (not that I have finished learning) how to overclock haswell. I could try again since I need to retest settings for new bios came out. A lot has changed since the first "i" series cpus (socket 1366).

    Disabling HT on my 4770k so far with LinX did not try others seems pointless. little to no temp drop and vcore I was able to drop from 1.21v to 1.20v

    Has anyone tried LinX with the newest Linpack (11.0.5.009) on default settings? I get the same crash after one rep that I do with an OC'd rig.

    Linpack 11.0.5.009 does make it through when I use the Linpack sample script, but then it stops using 2 cores during the middle of the run, with lower Gflops -- around 100 or so. When I run LinX + Linpack 11, during the single run it does work, it uses all 8 threads at 160 GFlops.

    What am I doing wrong?

    Based on some advice, I disabled HT, then ran Linpack 11.0.5.009 from its batch file. LinX with Linpack 11.0.5.009 has been crashing after 1 rep, and that is why I went with the batch file. For now, CPU is at default. Here are the results:

    So I upped the cpu to 4.4GHz, but it still got too hot and I had to cut Linpack short. So I dropped the cpu speed to 4.2GHz and reduced some Voltages. Linpack still got too hot, but I was able to grab one rep before I killed it:

    Linpack does not have a GUI. LinX and IBT and OCCT provide GUI's for Linpack.

    I cannot get my LinX to work with Linpack 11 more than one rep, even at default speed. Hence my using the script.

    I modified the data input file to this:

    Code:
    Sample Intel(R) Optimized LINPACK Benchmark data file (lininput_xeon64)
    Intel(R) Optimized LINPACK Benchmark data
    1                         # number of tests
    25000 # problem sizes
    25000 # leading dimensions
    20    # times to run a test
    4     # alignment values (in KBytes)
    Note that the name of the file is lininput_xeon64. You may wish to copy and rename the original as lininput_xeon64_old or some such. Also, I had to disable HT. Finally, do nursemaid the initial runs with something like Real Temp. It doesn't take long (50 seconds per rep at 4.2GHz) but the system gets really hot really quickly -- hotter than with Linpack 10.
